 Ajuda del GSview
1Introducció
-Overview
?Introducció
 El `GSview` és una interfície gràfica per al Ghostscript sota l'MS-Windows,
 l'OS/2 o el GNU/Linux.
 El Ghostscript és un intèrpret per al llenguatge de descripció de pàgines PostScript
 que utilitzen les impressores làser.
 Per als documents que segueixen les convencions d'estructura dels documents 
 Adobe PostScript, el GSview permet visualitzar o imprimir-ne les pàgines seleccionades.
 El GSview 4.8 necessita el Ghostscript 7.04 - 9.19.

WP
 Es recomana que utilitzeu el programa d’instal·lació per instal·lar el
 GSview.  Les instruccions següents descriuen com instal·lar el GSview
 sense utilitzar el programa d’instal·lació.

 Definiu la variable d’entorn TEMP perquè apunti a un directori per als
 fitxers temporals. Per exemple:
   SET TEMP=c:\temp
 El directori ha d’existir i ha d’estar-hi permesa l’escriptura.

 Primer necessiteu instal·lar el Ghostscript, més els seus fitxers de biblioteca i fonts.
 Necessiteu la versió del Ghostscript que hi ha llistada a la `Introducció`.
 Aquesta versió del GSview no funcionarà amb d’altres versions del Ghostscript.
 Instal·leu el Ghostscript al directori c:\gs\gsN.NN
 (Reemplaceu N.NN per el número de la versió del Ghostscript.)

 Creeu un directori c:\ghostgum\gsview

 Després instal·leu
P
 el PM GSview copiant el gvpm.exe, gvpgs.exe,
 gvpmde.dll, gvpmes.dll, gvpmfr.dll, gvpmit.dll,

 i el printer.ini
WP
 al directori  `c:\ghostgum\gsview`.

P
 Inicieu el GSview i després seguiu les instruccions que es donen a l’auxiliar
 de configuració. Això configurarà automàticament la
 `Opcions` | `Configuració avançada`, copieu una llista de les impressores
 conegudes al fitxer INI,
 i creeu una drecera del GSview a l’escriptori.

 Si voleu executar l’auxiliar de configuració més tard, utilitzeu
 `Opcions` | `Configuració fàcil`.
W
 Inicieu el GSview i seleccioneu la versió apropiada del Ghostscript
 (normalment l’última). Per canviar-ho més endavant, utilitzeu
 `Opcions` | `Configuració fàcil`.

?Manual avançat d’instal·lació
WP
 En lloc d’utilitzar `Opcions` | `Configuració fàcil`, utilitzeu
 `Opcions` | `Configuració avançada`.

 Primer definiu correctament els tres camps de texts (vegeu `Configuració avançada`).

P
 Sortiu del GSview, i després afegiu el printer.ini al fitxer INI del GSview
 (c:\os2\gvpm.ini).

 Creeu una drecera a l’escriptori per al GSview, tot associant-la amb
 les extensions de fitxer .ps, .eps i .pdf.

W
 Al quadre de diàleg `Configuració avançada`, seleccioneu els quadres de verificació
 `Copia els paràmetres predeterminats de la impressora`, `Associa els fitxers .ps amb el GSview` i
 `Crea elements al menú d’inici`, o seguiu respectivament els següents tres passos.

 1. Sortiu del GSview, i després afegiu el printer.ini al fitxer INI del GSview
 (c:\windows\gsview32.ini)

 2. Afegiu els tipus de fitxer .ps i .eps (i opcionalment els .pdf)
 al `Registre`.

 3. Creeu un element al Gestor de programes o al menú d’inici per al GSview.
X
 Després d'iniciar el GSview, utilitzeu a `Opcions` | `Configuració avançada`.
 Definiu la versió del Ghostscript perquè coincideixi amb la còpia del Ghostscript.
 Si el `gs -h` us diu 5.50, introduïu 550.  Si el `gs -h` us diu 6.50, introduïu 650.
 Definiu correctament els tres camps següents (vegeu `Configuració avançada`).
E

 Si teniu alguns tipus de lletra Type 1 al sistema, és possible dir-li
 al Ghostscript que les utilitzi.  Vegeu `Fontmap.os2` i `Fontmap.atm`
 que es donen amb el Ghostscript per a exemples.  Vegeu el tema `Fonts`.

 Si teniu problemes, proveu de llegir el tema d'ajuda `Problemes comuns`.

3Instal·lació de xarxa
-Network_Installation
?Instal·lació de xarxa
?Perfils d'usuari
 Instal·leu el GSview a un directori de la xarxa.

 Quan un usuari iniciï el per primer cop, o iniciï el GSview
 després que el número de versió hagi canviat, el GSview configurarà
 l'ordinador local.

 L'ús d'un directori UNC quan s'instal·la el GSview no funciona
 des del Windows 3.1, però si des del Windows 95.

W
 El GSview intenta mantenir un fitxer de configuració per cada usuari.
 Si els perfils d'usuari s'estan utilitzant sota el Windows 95 o l'NT,
 el GSview emmagatzemarà el fitxer INI al directori del perfil de l'usuari,
 tal i com s'indiqui al registre.  Si aquest no es pot trobar,
 i la variable d'entorn USERPROFILE s'ha definit i és un
 directori, el GSview emmagatzemarà el fitxer INI a aquest directori.
 Si això fallés, el GSview emmagatzemarà el fitxer INI a la ubicació
 predeterminada, el directori del Windows.
 Si el directori del perfil de l'usuari existeix, però hi té protegida l'escriptura,
 el GSview tindrà un problema.

WP
 Si voleu que el GSview no us mostri la `Configuració fàcil`
 quan s'executa per primer cop, o sempre que s'actualitzi el GSview,
 situeu un fitxer INI al directori del GSview.
 `Recordeu suprimir aquest fitxer abans d'actualitzar el GSview en el futur.`
 Només hauria de contenir aquelles entrades que voleu sobreescriure
 a la configuració dels usuaris.
 La tècnica que es suggereix és instal·lar el GSview, i després configurar-lo.
 Copieu el gsview32.ini o el gvpm.ini del directori del sistema o del directori
 del perfil de l'usuari al directori del GSview, i després editeu-lo per
 suprimir totes les entrades excepte:
  [GSview-4.8]
  Version=4.8
  GSversion=853
  Configured=1
  GhostscriptDLL=e:\gs\gs8.53\bin\gsdll32.dll
  GhostscriptInclude=e:\gs\gs8.53\lib;e:\gs\fonts
  GhostscriptOther=-dNOPLATFONTS -sFONTPATH="c:\psfonts"
 Quan un usuari inicia el GSview, normalment s'utilitza el seu fitxer INI.
 El primer cop que s'inicia el GSview, o quan la versió del GSview no
 coincideix amb el fitxer INI, passa el següent:

 1. Es llegeix el fitxer INI al directori del GSview, tot substituint
 el fitxer INI dels usuaris.

 2. S'actualitza la llista d'impressores al directori
 del GSview.

 3. NO es fan o es canvien associacions dels fitxers (.ps, .eps, .pdf).
 Si les voleu canviar heu d'utilitzar `Opcions` | `Configuració avançada`.

 4. NO es canvien els grups del Gestor de Programes / elements del menú d'inici / 
 dreceres del programa.
 Si els voleu canviar heu d'utilitzar `Opcions` | `Configuració avançada`.
W

 Si l'esteu instal·lant al Windows NT4/2000, i seleccioneu "Tots els usuaris",
 llavors l'instal·lador escriurà aquest gsview32.ini al directori del GSview.
 Heu de tenir instal·lat el Ghostscript primer.

 Quan un usuari intenta utilitzar el programa de desinstal·lació del GSview, 
 s'intenta suprimir els fitxers del GSview i del Ghostscript a la xarxa.
 Assegureu-vos que els directoris del GSview i del Ghostscript no poden ser escrits
 pels usuaris.
 Per a més seguretat, podeu suprimir el fitxer `uninstal.txt` del directori
 del GSview.

 Alternativament, si voleu instal·lar el GSview a cada ordinador sense
 cap sol·licitud, descomprimiu l'arxiu autoextraïble i després executeu
 el programa d'instal·lació així:
  setup -nom "El vostre nom" -numero XXXXX-XXXXX "c:\ghostgum"
E

3Execució del GSview des del Gestor de fitxers o l'Explorador del Windows
-Running_from_Windows_Explorer
?Editor de la informació de registre
?Gestor de fitxers
?Explorador del Windows
?Registre
 Si heu utilitzat el programa setup.exe del GSview i heu contestat `sí` a
 a totes les preguntes, la configuració següent ja ha ocorregut.
 Si no vau actualitzar el registre durant la instal·lació del GSview,
 la informació següent us explica com fer-ho manualment.

 Per executar el GSview quan es fa doble clic a un fitxer PostScript al
 Gestor de fitxers, s'ha de seguir la seqüència següent per ensenyar-li
 al Gestor de fitxers quant als fitxers PostScript.

 Des del `Gestor de programes`, executeu l'Editor d'informació del registre
 `Fitxer `| `Executa...` i teclegeu `regedit`.
 Des de l'`Editor d'informació del registre` seleccioneu `Edita `| `Afegeix un tipus de fitxer...`
 i introduïu els camps següents:
  Identificador = psfile
  Tipus de fitxer = PostScript
  Acció = Open
  Ordre = c:\ghostgum\gsview\gsview32 %1
  Utilitza DDE = Sense marcar
  Acció = Print
  Ordre = c:\ghostgum\gsview\gsview32 /p %1
  Utilitza DDE = Sense marcar
 Llavors premeu `D'acord`.

 Des del `Gestor de fitxers`, seleccioneu `Fitxer `| `Associa` i llavors
 introduïu els següents camps:
  Fitxers amb l'extensió = ps
  Associa amb = PostScript (gsview)
 Desrpés premeu `D'acord`.

 Ja està! Ara quan feu doble clic a un fitxer PostScript,
 el `Gestor de fitxers` executarà el GSview.  Quan arrossegueu un fitxer 
 PostScript al `Gestor d'impressió`, el GSview imprimirà el fitxer.
 Si teniu una impressora PostScript, això no us serà útil.
 En aquest cas, haureu de suprimir l'acció Print
 del registre.

 Per al Windows 95, la configuració es fa amb l'Explorador
 del Windows.

 Inicieu l'`Explorador del Windows`.  Seleccioneu `Visualització` | `Opcions`.  Seleccioneu la
 pestanya `Tipus de fitxers`.  Seleccioneu el botó `Crea un tipus`.
 Introduïu els següents camps:
  Descripció del tipus = PostScript
  Extensió associada = PS EPS
 Premeu el botó `Crea`, i introduïu
  Acció = open
  Aplicació utilitzada per dur a terme l'acció = c:\ghostgum\gsview\gsview32.exe
 Premeu el botó `D'acord`

 Premeu el botó `Crea`, i introduïu
  Acció = print
  Aplicació utilitzada per dur a terme l'acció = c:\ghostgum\gsview\gsview32.exe /p
 Premeu el botó `D'acord.`

 Premeu el botó `Tanca.`

 Premeu el botó `Tanca.`

2Registre
-Registration
?Registre
 Si voleu permetre el desenvolupament del GSview, o bé voleu inhabilitar-ne
 la pantalla empipadora, si us plau, penseu el fet de registrar-lo.
 Tanmateix, no teniu cap necessitat de registrar el GSview.
 El GSview està disponible sota la Llicència Pública Gratuïta d'Aladdin (l'AFPL, 
 Aladdin Free Public Licence), continguda al fixer `LICENCE`.
 Això permet l'ús gratuït, però en restringeix la distribució comercial.

 Ara mateix l'import del registre és de 40 AUD$.
 El GSview es pot registrar en línia a
  http://www.ghostgum.com.au/
 o enviant per fax o per correu el
 formulari de registre que podeu trobar al fitxer `regorder.txt`
 al directori del GSview.
 Ghostgum Software prefereix que utilitzeu el registre en línia.
2Convencions de l'estructura del document
-DSC
?Convencions de l'estructura del document
?DSC
?PostScript encapsulat
?EPSF
?EPS
 Adobe ha definit un conjunt de convencions de comentaris esteses que donen
 informació addicional quant a l'estructura de la pàgina i els requeriments
 dels recursos d'un fitxer PostScript.
 Si un fitxer conté aquests comentaris de Convencions de l'estructura del document (DSC),
 el GSview pot visualitzar pàgines en un ordre aleatori utilitzant `Vés a la pàgina` i
 pàgines en ordre invers utilitzant `Pàgina anterior`. Les pàgines seleccionades es poden
 extreure a un altre fitxer o imprimir-se.

 Si un fitxer no conté comentaris DSC, el GSview només pot visualitzar-ne pàgines
 en l'ordre original.

 Els fitxers conformes amb els DSC s'inicien amb la línia de comentari:
  %!PS-Adobe-3.0
 on el número 3.0 pot canviar i és el número de la versió dels DSC.
 Alguns programes escriuen fitxers PostScript amb un control-D com a primer
 caràcter del fitxer, seguit de la línia de comentari anteriorment esmentada.
 El GSview informarà correctament què aquests fitxers no són conformes amb els DSC,
 però tot i així els visualitzarà amb les característiques de selecció de pàgina disponibles.
 Queixeu-vos a l'autor del programa que va fer el fitxer PostScript.
 Per fer el fitxer conforme amb els DSC, editeu-lo i suprimiu-ne el caràcter control-D.

 Els fitxers conformes amb els DSC contenen línies com:
  %%Pages: 24
  %%Page: 1 1
 Aquestes línies diuen al GSview quantes pàgines conté un document i
 on comencen. El GSview utilitza aquesta informació per seleccionar pàgines
 individuals.

 Els fitxers PostScript encapsulats (EPSF) són documents d'una sola pàgina
 que contenen un subconjunt dels comentaris `DSC` i ordres PostScript.
 Els fitxers EPS s'inicien amb la següent línia de comentari:
  %!PS-Adobe-3.0 EPSF-3.0
 Els fitxers EPS s'utilitzen principalment com a inclusions en d'altres documents
 i per aquesta raó requereixen el comentari del requadre del límit:
   %%BoundingBox: llx lly urx ury
 on llx, lly, urx i ury són enters que donen les coordenades x i y
 de les cantonades inferior esquerra i superior dreta d'un requadre del límit que 
 tanca tots els elements de la pàgina.

 Alguns fitxers EPS contenen una visualització prèvia del document PostScript.
 Aquesta visualització pot ser un metafitxer del Windows, un fitxer TIFF, o una visualització
 prèvia d'intercanvi (format EPSI).
 Per als metafitxers del Windows o els fitxers de visualització prèvia TIFF, el fitxer EPS
 sota el DOS conté una capçalera binària que indica la ubicació i longitud de la visualització
 prèvia i les seccions de llenguatge PostScript del fitxer EPS.
 Per al format d'intercanvi, la visualització prèvia està continguda als comentaris DSC
 que comencen per
  %%BeginPreview: amplada alçada profunditat línies
 Un fitxer EPS amb visualització prèvia es pot crear des d'un fitxer EPS sense
 visualització prèvia tot utilitzant `Afegeix una visualització prèvia EPS`.

 El GSview pot donar avisos quan els documents contenen comentaris DSC
 incorrectes.  Això es pot canviar amb `Opcions` | `Avisos DSC`.
2Format de document portàtil (PDF)
-PDF
?Format de document portàtil (PDF)
?PDF
?pdf2ps
?ps2pdf
 El GSview pot visualitzar i imprimir fitxers PDF, tot i que hi ha un seguit de
 limitacions amb el mètode actual.

 Quan s'està visualitzant, el GSview ignora la mida de la pàgina del menú Suport,
 i en el seu lloc utilitza el /MediaBox del fitxer PDF.
 Si s'habilita el `Opcions` | `Retalla els EPS`, el GSview utilitzarà el /CropBox
 del fitxer PDF.

 El GSview necessita que feu `Obre` un fitxer PDF per comptar-ne les pàgines. Si
 feu `Selecciona` un fitxer, el GSview no serà capaç de fer `Extreu el text`,
 `Cerca`, `Vés a la pàgina` o realitzar qualsevol altre operació que necessiti
 saber quantes pàgines hi ha al document.

 La compatibilitat amb els enllaços pdfmark no és completa.

 Per convertir un fitxer PostScript a un de PDF, utilitzeu `Fitxer` | `Converteix`,
 i després seleccioneu el dispositiu `pdfwrite`.

 Per convertir un fitxer PDF a un de PostScript, utilitzeu `Fitxer` | `Converteix`,
 i després seleccioneu el dispositiu `pswrite`.

 `Fitxer` | `Extreu` no funciona pels fitxers PDF.
 L'extracció de pàgines PDF extreu més aviat PostScript que no pas PDF.


 Per convertir massivament diversos fitxers, mireu a
X
 ps2pdf.
WP
 ps2pdf.bat i pdf2ps.bat
 al directori del Ghostscript.
 Necessitareu utilitzar
P
 gvpm.exe
W
 gswin32c.exe
WP
 en lloc del gs.exe.  També necessitareu definir el directori d'inclusió 
 del Ghostscript utilitzant `-I` o la variable d'entorn `GS_LIB`.
E
2Obertura d'un document
-Open
?Fitxer
?Obre
?Selecciona un fitxer
?Anomena i desa
?Tanca
 L'ordre `Obre` al menú `Fitxer` obre un fitxer i en visualitza
 la primera pàgina.

 Si el fitxer conté comentaris `DSC`, les pàgines es poden seleccionar utilitzant
 `Pàgina següent`, `Pàgina anterior` i `Vés a la pàgina`.

 Si el fitxer no conté comentaris `DSC`, `Pàgina anterior` i `Vés a la pàgina`
 no funcionaran. No s'hauria de seleccionar un altre fitxer fins que es visualitzi
 l'última pàgina del document.

 Quan s'obre un fitxer, el GSview en visualitza el nom del fitxer,
 la pàgina actual (si està disponible) i mentre el cursor és sobre la imatge,
 la ubicació del cursor en les coordenades que s'han indicat
 a `Opcions` | `Unitats`.  Les coordenades poden ser punts del PostScript
 (1/72"), mil·límetres o polzades.
 La ubicació del cursor és útil per calcular els requadres del límit.

 L'ordre `Selecciona un fitxer` és similar a `Obre` però aquesta no visualitza
 el document.
 Aquesta ordre és útil per obrir documents abans d'imprimir-los.

 L'ordre `Anomena i desa` desa una còpia del document actual.
 Això és útil si s'està utilitzant el GSview com a visualitzador de PostScript per
 altres aplicacions i voleu desar el fitxer que s'està visualitzant actualment.

 L'ordre `Tanca` tanca el document obert actualment.
 Això s'haurà d'utilitzar abans que un altre programa canviï el fitxer
 actual.
 Si no voleu fer-ho i el GSview detecta que la mida o la data del fitxer
 han canviat, es tancarà el Ghostscript i es tornarà a escannejar el document.

 Vegeu també `Imprimeix`.
2Selecció de la pàgina
-Page_Selection
?Selecció de la pàgina
?Pàgina següent
?Pàgina anterior
?Torna a dibuixar
?Vés a la pàgina
?Visualitza
?Ajusta la finestra
?Pantalla completa
 `Visualitza` | `Pàgina següent` o el botó `+` mouen el document una
 pàgina endavant.
 Això funciona fins i tot si el document no té comentaris `DSC`.

 `Visualitza` | `Pàgina anterior` o el botó `-` mouen el document una pàgina endarrere.

 `Visualitza` | `Torna a dibuixar` o la tecla `F5` tornen a visualitzar i dibuixar la pàgina actual.

 `Visualitza` | `Vés a la pàgina` o el botó de la `mà que apunta` mostra un quadre de diàleg
 que us permet seleccionar el número de la següent pàgina a mostrar.
 El quadre diàleg `Selecciona la pàgina` mostra les etiquetes de les pàgines perquè acostumen a
 ser més útils que una numeració de pàgines seqüencial.

 `Visualitza` | `Pàgina següent i inicial` o la barra d'espai mouen el document a la part superior
 de la pàgina següent.

 `Visualitza` | `Pàgina anterior i inicial` o la tecla de retrocés mouen el document
 a la part superior de la pàgina anterior.

 Les ordres `Pàgina anterior`, `Torna a dibuixar` i `Vés a la pàgina` només funcionen si el
 document conté comentaris `DSC`.

 `Visualitza` | `Ajusta la finestra` o la tecla `F6` canvien la resolució de visualització
 per ajustar la pàgina sencera a la finestra actual. L'ús repetit
 fa que tant l'amplada com l'alçada de la pàgina s'ajustin a la finestra
 actual.

 `Visualitza` | `Pantalla completa` o la tecla `F4` visualitzen la pàgina a pantalla completa
 (sense la barra del títol, les barres de desplaçament, etc.).
 Per tornar a la visualització normal, premeu la tecla d'escapada.
2Informació del document
-Document_Information
?Informació
 S'utilitza una àrea d'informació breu a la part superior de la finestra del
 GSview per visualitzar el nom de fitxer del document, el número i etiqueta de la pàgina
 actual (si està disponible) i mentre el cursor és sobre la imatge, la ubicació del cursor
 (relativa a la cantonada inferior esquerra del paper) 
 amb les coordenades que s'han especificat a `Opcions` | `Unitats`.
 La ubicació del cursor és útil per calcular els requadres del límit.

 L'ordre `Informació` al menú `Fitxer ` mostra un quadre de diàleg amb la informació
 següent quant als comentaris `DSC` al document actual.

 El `Fitxer `és el nom del camí del document complet.

 El `Tipus` pot ser` DSC`,` EPS`, `Sense comentaris DSC` o `S'estan ignorant els comentaris DSC`.
 L'`EPS` és un fitxer PostScript encapsulat - un document d'una sola pàgina
 que conté un subconjunt de comentaris `DSC` i d'ordres PostScript.
 Els fitxers `EPS `s'utilitzen normalment com inclusions a d'altres documents.
 `S'estan ignorant els comentaris DSC` es mostra si se selecciona `Opcions` | `Ignora els DSC`.
 Aquests poden tenir el prefixe `Ctrl-D seguit de` o `PJL seguit de`.
 Els dos indiquen que el document no compleix amb els DSC
 perquè hi ha brossa al principi del document.
 Per arreglar el primer, vegeu `Problemes comuns`.
 Per arreglar el segon, no utilitzeu un controlador HP LaserJet quan creeu
 documents PostScript per a distribuir als altres.

 El `Títol` és un text que es pot utilitzar quan s'imprimeixen pàgines
 i per escannejar i reconèixer documents.

 La `Data` és la data de quan es va crear el document.

 El `Requadre del límit` delimita un requadre que tanca tots els elements pintats
 a la pàgina.  Els quatre valors enters són coordenades de les cantonades
 inferior esquerra i superior dreta del requadre del límit en les coordenades
 predeterminades de l'usuari (1/72 polzades).

 L'`Orientació `és la orientació predeterminada de la pàgina i pot ser tant
 `Horitzontal `com` Vertical`.  Vegeu el menú `Orientació`.

 L'`Ordre de pàgines` pot ser tant `Ascendent`, `Descendent` com `Especial`.
 Si l'`Ordre de pàgines` és `Descendent`, el GSview inverteix automàticament
 les pàgines quan s'està visualitzant, o quan s'està imprimint de manera que apareixen en ordre ascendent.  
 Quan s'extreu o s'imprimeix, el GSview pot rebre instruccions
 d'imprimir les pàgines en ordre descendent (invers).
 `Especial` significa que les pàgines no s'han de tornar a ordenar.

 El `Suport predeterminat` dóna el nom del suport seguit de l'amplada i l'alçada
 d'aquest suport en les coordenades predeterminades de l'usuari (1/72 polzades).

 Les `Pàgines` són el número total de pàgines del document.

 La `Pàgina` dóna l'etiqueta i el número de la pàgina.

 El `Mapa de bits `és la mida del mapa de bits que es visualitza, cosa que pot ser
 útil si copieu al porta-retalls la imatge que es visualitza.

2Impressió
-Print
?Imprimeix
 L'ordre `Imprimeix` del menú `Fitxer ` permet la impressió del document
 tot utilitzant el Ghostscript.  Hi ha tres mètodes que utilitza el GSview per
 imprimir: `Impressora Windows GDI`, `Dispositiu Ghostscript`
 o `Impressora PostScript`.

 `Impressora Windows GDI` utilitza el Ghostscript per crear mapes de bits per
 cada pàgina, i les imprimeix fent ús del dispositiu estàndard del Windows.
 Aquest és el mètode més lent, però hauria de funcionar amb la majoria d'impressores.

 `Dispositiu Ghostscript` utilitza els dispositius d'impressores del Ghostscript.
 Aquest és més ràpid, però necessiteu que el Ghostscript tingui un controlador de
 la vostra impressora i necessiteu saber com es diu.
 Per exemple, l'HP LaserJet 4 utilitza el ljet4.
 Vegeu la documentació del Ghostscript per a més detalls.

 `Impressora PostScript` no utilitza el Ghostscript per imprimir els fitxers
 PostScript. En lloc d'això, s'envia el fitxer directament a la impressora.

 Hi ha una quantitat significativa d'interacció entre els paràmetres
 al quadre de diàleg d'impressió. Per exemple, seleccionar `Dispositiu `
 inhabilita el botó `Propietats ` perquè no és rellevant.
 Hi ha més detalls als temes següents.

 Vegeu també `Conversions` i `Converteix`.
3Selecció de pàgines
-Select_Pages
?Selecció de pàgines
 Quan s'imprimeix, es pot seleccionar un rang de pàgines.
 Dins aquest rang, podeu seleccionar totes les pàgines o les pàgines parelles o imparelles.
 Si seleccioneu pàgines imparelles al rang de 10 a 20, la primera pàgina que s'imprimirà
 serà la 11.

 El botó `Selecciona` es pot inhabilitar si no és compatible amb el mètode d'impressió.

 El quadre de verificació `Inverteix` fa que les pàgines s'imprimeixin en
 ordre descendent. Això s'habilita únicament si el document conté comentaris `DSC`.

 Si voleu imprimir les pàgines des d'un document `DSC` que tingui un ordre de pàgines
 especial (per exemple, que les pàgines no es puguin tornar a ordenar),
 seleccioneu la `Impressora Windows GDI` i `Ignora els DSC`.
3Impressora Windows GDI
-Windows_GDI_printer
?Impressora Windows GDI
 Utilitza el Ghostscript per crear un mapa de bits per a cada pàgina, i
 aquests s'imprimeixen tot utilitzant el dispositiu estàndard d'impressió del Windows.
 Hauria de funcionar amb totes les impressores que són compatibles amb l'impressió de gràfics.

 Per defecte, s'utilitza un mapa de bits monocrom per a una màxima velocitat.
 Si voleu color, necessitareu habilitar-ho utilitzant el botó `Paràmetres `.

 Per controlar com gestiona les sol·licituts de canvi de mida de la pàgina 
 per als documents PostScript o PDF el GSview, vegeu el tema
 `Ajust de la mida de la pàgina`.

 Les `Opcions `normalment són buides, però poden contenir opcions en línies d'ordres.
 Utilitzeu-ho amb cura!

 Aquest mètode d'impressió permet imprimir les pàgines seleccionades, fins i tot si
 un document PostScript no conté comentaris `DSC`.  Ho fa
 mitjançant la representació de totes les pàgines, però només enviant a la impressora les que se sol·liciten.
 Podria ser molt lent.
3Ghostscript device
-Ghostscript_device
?Ghostscript device
?uniprint
 The `Select Ghostscript Device` dialog box allows selection of
 the Ghostscript printer device and resolution.
 The default list of available devices and resolutions is stored
 in the [Devices] section of gsview32.ini and is taken from the
 standard distribution version of Ghostscript 6.0.
 You can use other devices or resolutions.

 To control how GSview handles requests by the PostScript or
 PDF documents to change the page size, see the
 `Page Size Matching` topic.

 Some Ghostscript options may be added using either the` Options`
 field or the `Properties` button.

 The `uniprint` button selects the uniprint device and displays a list
 of available configuration files (*.upp) for the uniprint device.
 If you select one of these configuration files, the configuration file
 name will be placed in the `Options `field of the Printer Setup.
 See the Ghostscript file `Devices.htm` for details of how to configure
 the uniprint device.
3PostScript printer
-PostScript_printer
?PostScript printer
 If `PostScript Printer` is selected, the selected pages will be
 sent direct to the printer queue, without using Ghostscript.
 This is similar to `File `| `Print File`, except that you can specify
 which pages to print.

 When a PostScript printer is connected via a serial port, it sometimes
 requires a Ctrl+D character to be sent after the PostScript file,
 and depending on how well behaved other programs are, sometimes before.
 This is part of the serial communications protocol used by these
 printers - it is not part of PostScript.
 The `Settings `dialog allows you can choose to
 send Ctrl+D before and/or after the PostScript file.

 Some PostScript printers understand multiple languages, and
 require a prolog to enable the PostScript mode.
 For example, HP LaserJet printers (with the PostScript option)
 require the following prolog
  ^[%-12345X@PJL JOB
  @PJL ENTER LANGUAGE = POSTSCRIPT
 and the following epilog
  ^[%-12345X@PJL EOJ
  ^[%12345X
 The prolog and epilog files allow you to send a file to the
 printer before and after the PostScript file.

 Another use of the prolog might be to invoke duplex printing
  << /Duplex true /Tumble false >> setpagedevice

 If the document is `PDF`, Ghostscript will be used to convert
 the document to PostScript which will then be sent to the printer.
3Print File
-Print_File
?Print File
 `File | Print File` sends a file to a local port, bypassing the
 Windows printer drivers.
 This is useful for sending a document to a PostScript printer,
 or for sending an output file produced by Ghostscript to a printer.

 program for queuing print jobs.
E

 All pages, individual pages or any combination may be printed.
 The `All`, `Odd` and `Even` buttons provide quick selection of pages.
 If a single contiguous block of pages is marked, the `Odd` and `Even`
 buttons will select odd or even pages within this range.
 The `Reverse` check box causes the pages to be printed in
 descending order.

P
 The `os2prn` printer driver uses the OS/2 printer drivers
 and should work with any printer with raster capabilities.
 Printer resolution cannot be selected from within GSview; use
 the Printer Object instead.  The printer default settings
 must match those expected by Ghostscript; printer page orientation
 must be Portrait, printer page size must match the Ghostscript page
 size.  Setting the property -dBitsPerPixel=1 should speed up
 printing a little.

 With all other printer drivers, Ghostscript sends the output direct
 to the printer queue.
 If you have trouble printing you may have to `Print To File`
 and then `Print File` or use the OS/2 command `COPY /B FILENAME PRN`.
PX

 If `PostScript Printer` is checked, the selected pages will be
 sent direct to the printer queue, without using Ghostscript.
 This is similar to `File | Print File`, except that you can specify
 which pages to print.  The `Advanced` button allows prolog and
 epilog files to be placed around the PostScript being sent to
 a PostScript printer.

 The list of available devices and resolutions is stored in the
 [Devices] section of

 The `uniprint` button selects the uniprint device and displays a list
 of available configuration files (*.upp) for the uniprint device.
 If you select one of these configuration files, the configuration file
 name will be placed in the `Options `field of the Printer Setup.
 See the Ghostscript file `Devices.htm` for details of how to configure
 the uniprint device.

 The `Printer Setup` dialog box prompts you for the name of a printer
 queue to which output should be sent.
 This queue will be saved and will be the default selection next time.

3Properties
-Properties
?Properties
 The `Properties` button allows some Ghostcript devices to configure
 extra properties and a page offset to be specified.

 A page offset can be specified for each device.
 The page offset is useful for correcting a mismatch between the page
 origin of a Ghostscript printer device and a particular printer.
 Increasing the X value will translate the image towards the right.
 Increasing the Y value will usually translate the image downwards.

 `Properties` are typically used to set BitsPerPixel for a colour
 printer, or other types of colour or density correction,
 or PDF distiller parameters.

 `Properties` are specific to a particular device.  Changing
 the value of the `BitsPerPixel` property on one device does not
 change it for any other device.

 When you press the `OK` button in the `Properties` dialog
 box, the current settings are written to the
W
 gsview32.ini
P
 gvpm.ini
X
 ~/.gsview.ini
E

 file.

 Some `Properties` are predefined in GSview, but these may not
 match those available in Ghostscript.  The `Edit `and `New`
 buttons allow you to modify available `Properties` for that device.
 See the `Edit Properties` topic for more details.
4Edit Properties
-Edit_Properties
?Edit Properties
 Not every device supports the use of optional `Properties`.  To find
 out which devices support `Properties` and which `Properties` are
 recognised by each device, read the Ghostscript
 file Devices.htm or look at the Ghostscript source code.

 There are two ways to add or edit `Properties`.

 The first method uses the `Edit `or `New` button on the `Properties`
 dialog box.

 Each property must be either a number or a string.  Number properties
 are equivalent to the Ghostscript `-d` command line option.  String
 properties are equivalent to the Ghostscript `-s` command line option.
 Each property consists of a `Name` and `Value`.  These are used as
 `-dNAME=VALUE` or `-sNAME=VALUE`.
 The `Value` is chosen from the comma separated list of `Values`
 entered into the `Edit Properties` dialog box.  Spaces must not
 be embedded in the `Name` or `Values`.

 To delete a property, select it on the `Properties` dialog box,
 then press` Edit`, then press the `Delete` button on the `Edit Properties`
 dialog box.

 The second method is to manually edit the GSview INI file.

 For each device, you must add two sections to the
W
 gsview32.ini
P
 gvpm.ini
X
 ~/.gsview.ini
E
 file.
 The following example shows how to add property information
 for the cdjcolor driver.
 First add a section which gives the current values.
 This section, after the first character is removed, gives the options
 that will appear in the `Property` list box.
 The first character is `s` for string or `d` for number.
  [cdjcolor]
  dBitsPerPixel=24
  dDepletion=1
  dShingling=2
  dBlackCorrect=4

 Next add a section which gives the values to display in the
 `Value` list box.
  [cdjcolor values]
  dBitsPerPixel=1,3,8,16,24
  dDepletion=1,2,3
  dShingling=0,1,2
  dBlackCorrect=0,1,2,3,4,5,6,7,8,9
 GSview will also add the value `[Not defined]` to the listbox.

 When GSview prints a file, it will give Ghostscript the contents
 of the [cdjcolor] section of
W
 gsview32.ini
P
 gvpm.ini
X
 ~/.gsview.ini
E
 as follows:
  -dBitsPerPixel=24 -dDepletion=1 -dShingling=2 -dBlackCorrect=4
 If the value of a property is `[Not defined]`, that property will
 not be sent to Ghostscript.
3Page Size Matching
-Page_Size_Matching
?Page Size Matching
?Fixed Media
?Fixed Page Size
?Variable Page Size
?Shrinkg to fit Page Size
 If `Fixed Page Size` is selected (the default), GSview will use the
 page size on the Media menu and will ignore attempts by PostScript
 or PDF documents to change the page size.
 This is useful for PDF files that contain a mix of portrait and
 landscape pages.

 If `Shrink to fit Page Size` is selected, any page size selected
 by the document that is larger than the selected media will
 be shrunk to fit the page size on the Media menu.
 This is useful if you want to print an A4 sized page on
 letter paper (although a better idea is to buy A4 paper).

 If `Variable Page Size` GSview will set the default page
 size from the Media menu, but allow the page size to be changed.
2Conversions
-Conversions
?Conversions
 There are several ways to convert PostScript and PDF files.

 `File `| `Convert` uses Ghostscript to convert PostScript or
 PDF to bitmaps, PostScript or PDF.

 `File `| `Extract` allows a range of pages to be copied from
 a PostScript document.

 `File `| `PS to EPS` allows the bounding box to be updated and
 allows the header to be changed from PS to EPS.
 Read the documentation thoroughly before using this.

 `Edit `| `Add EPS Preview` adds a bitmap preview to an EPS
 file.

 `Edit `| `Extract EPS` extracts the PostScript or Preview
 from a DOS EPS file.

 `Edit `| `Convert to vector format` uses pstoedit to convert
 PostScript or PDF to an editable vector format.

 `Edit `| `Text Extract` uses pstotext to extract text from
 a PostScript or PDF document.
WP

 `Edit `| `Copy` copies the display bitmap to the clipboard.
 `Edit `| `Paste To` copies a clipboard DIB bitmap to a file.
 `Edit `| `Convert Bitmap` converts a clipboard DIB bitmap
 to a clipboard device dependent bitmap.

3File conversions and tricks
-File_conversions_and_tricks
?File Conversions
?Tricks
 Some common file conversions that can be performed
 using GSview and Ghostscript are:

 Convert PostScript to PDF.
 File | `Convert`, select pdfwrite, 300dpi,
 With Ghostscript 5.50, fonts with non-standard encodings
 will be included as bitmaps.  If you choose 72dpi, fonts
 will look rough.  Ghostscript 6.0 will embed fonts.

 Convert PDF to PostScript.
 File | `Convert`, select pswrite, 300dpi.

 Convert Level 2 PostScript to Level 1 PostScript.
 File | `Convert`, select psmono, 300dpi,
 Instead of 300dpi, you should use the resolution of your
 printer.

 Convert to a bitmap.
 File | `Convert`, select bmp16m, 72dpi.

WP
 Convert to an editable vector format (pstoedit).
 Edit | `Convert to vector format` OR convert to PDF
 using the method above.

E
 Extract text (pstotext).
 Edit | `Text Extract`

 Add a preview to an EPS file.
 Edit | `Add EPS Preview`.   See `Add EPS Preview` for
 more details.

 Remove preview from an EPS file.
 Edit | `Extract EPS` | PostScript

 Display with smooth edges.
 Media | `Display Settings`.  Set `Text Alpha` and
 `Graphics Alpha` to 4.  You need a display with
 at least 8 bits per pixel.
WP

 Save the displayed bitmap.
 Edit | `Copy` to copy to the clipboard.
 To save to a BMP file, use Edit | `Copy` then `Paste To`...
E

 Create a bitmap with smooth edges (anti-aliasing).
WP
 1. Display with smooth edges and save the display bitmap.
 OR
 2.
E
 `Convert` using a bitmap device and set the following
 in the properties.
    -dTextAlphaBits=4 -dGraphicsAlphaBits=4
3Convert
-Convert
?Convert
 `File `| `Convert` uses Ghostscript to convert PostScript or PDF
 to bitmaps, PostScript or PDF.

 You need to select a Ghostscript output device and resolution.
 The default list of available devices and resolutions is stored
 in the [Convert] section of
W
 gsview32.ini
P
 gvpm.ini
X
 .gsview.ini
E
 and is taken from the standard distribution version of Ghostscript 6.01.
 You can use other devices or resolutions.

 Some Ghostscript options may be added using either the
 `Options `field or the `Properties` button.

 All pages, individual pages or any combination may be converted.
 The `All`, `Odd` and `Even` buttons provide quick selection of pages.
 If a single contiguous block of pages is marked, the `Odd` and `Even`
 buttons will select odd or even pages within this range.
 The `Reverse` check box causes the pages to be converted in
 descending order.

 To control how GSview handles requests by the PostScript or
 PDF documents to change the page size, see the
 `Page Size Matching` topic.

 See also `Conversions`.
3Extract
-Extract
?Extract
 `Extract` allows a range of pages to be copied from the current
 document to a new document.  For example, ten pages can be extracted
 from the middle of the current document and written to another file,
 which will later be sent to a printer.
 If you select `Reverse`, the extracted pages will be in descending
 order.

 See also `Conversions`.
3PS to EPS
-PS_to_EPS
?PS to EPS
?BoundingBox
 In general, it is not possible to convert a PostScript file to `EPS`.
 However, many single page PostScript files can be converted to `EPS`
 by changing the first line of the file to
  %!PS-Adobe-3.0 EPSF-3.0
 and then adding or fixing up the `%%BoundingBox` comment.

 EPS files are commonly used for inclusion in other documents and
 for this reason require the bounding box comment:
   %%BoundingBox: llx lly urx ury
 where llx, lly, urx and ury are integers giving the x and y co-ordinates
 of the lower left and upper right corners of a bounding box which encloses
 all marks made on the page.

 `When used incorrectly, the PS to EPS command can produce PostScript
 files with incorrect DSC comments.  Such a document will cause problems
 when you try to include it inside another document.`

 To convert a PostScript file to `EPS`, the original file `must` be
 a `single page` document.  If the document contains `DSC` comments
 and is multi page, extract the desired page with `File` | `Extract`.
 If the document does not contain `DSC` comments, you will need to
 edit the file by hand to extract the desired page.

 `EPS` documents `must not` use any of the following operators:
  banddevice   clear         cleardictstack  copypage
  erasepage    exitserver    framedevice     grestoreall
  initclip     initgraphics  initmatrix      quit
  renderbands  setglobal     setpagedevice   setpageparams
  setshared    startjob      letter          note
  legal        a3            a4              a5

 The following operators should be used with care:
  nulldevice   setgstate     sethalftone    setmatrix
  setscreen    settransfer   setcolortransfer

 It is `your` responsibility to make sure that the above requirements
 are met.

 To test if a document contains any of the above operators, select
 `Options` | `EPS Warn` and then `Open` the desired document.
 After the page has been displayed, `Close` the document and
 then display the Ghostscript messages with `File` | `Show Messages`.
 If any of the above operators have been used you should see lines like:
  Warning: EPS files must not use ...
 If you find these warnings then do `not` use `PS to EPS`.
 Remember to turn off `EPS Warn` afterwards.

 A document must be displayed before `PS to EPS` is used.

 For documents without `DSC` comments, `PS to EPS` allows a bounding
 box to be specified, then writes out an `EPS` file consisting of
 an `EPS` wrapper around the original document.

 For documents with `DSC` comments, `PS to EPS` will change the
 first line of the file to
  %!PS-Adobe-3.0 EPSF-3.0
 then allows the `%%BoundingBox` comment to be changed or added.

 For `EPS` documents, `PS to EPS` allows the `%%BoundingBox` comment to
 be changed.

 `PS to EPS` does not clip the document to the `%%BoundingBox`.
 To do so would require changing the PostScript code itself.
 `PS to EPS` only changes the `DSC` comments.

 If `Automatically calculate Bounding Box` is checked, GSview
 will calculate the bounding box from the non white pixels.
 If unchecked, you get to choose the bounding box by clicking at
 the left, bottom, right and top.

 `PS to EPS` does not add a preview to a document.
 If you want a preview you add it with `Edit `| `Add EPS Preview` after
 first creating an `EPS` file with a correct `%%BoundingBox`.

 See also `Add EPS Preview`, `Extract`, `EPS Warn` and `Conversions`.
3EPS Preview
-EPS_Preview
?EPS Preview
?Add EPS Preview
?Extract EPS
?Preview
 `Add EPS Preview` takes a bitmap from the
 display and uses it to add a preview to an EPS file.
 `Add EPS Preview` can create a DOS EPS file with a
 Windows Metafile or TIFF preview, or an EPSI file with an Interchange preview.
 To use the `Add EPS Preview` command the following steps must be followed.

 1. Deselect `Options | Ignore DSC`

 2. Make sure the document has a correct bounding box.
 `Options` | `Show Bounding Box` is useful for checking the
 bounding box.
 A bounding box can be added or changed using `File` | `PS to EPS`.

 3. Select `Orientation` | `Portrait`.

 4. Select `Media `| `Display Settings` and set a suitable resolution
 for the preview.  If the resolution is too high
 it will make the EPS file excessively large.

 5. `Open` an EPS file that does not contain a preview.

 6.  Select `Edit `| `Add EPS Preview`, then the preview format,
 then the new EPS filename.  GSview will write a new file containing
 the original PostScript EPS file and a preview created from the
 display bitmap.
 The available preview formats are `Interchange`,
 `TIFF 4`, `TIFF 6 uncompressed`, `TIFF 6 packbits` and `Windows Metafile`.
 If adding an Interchange preview, the document must have an `%%EndComments`
 line, otherwise GSview may put the preview in the wrong place.
 An interchange preview is always monochrome.
 A TIFF 4 preview is a Baseline Bilevel Image (1 bit/pixel) with
 no compression as described in the TIFF 6.0 memorandum, but avoiding
 tags which are not described in the TIFF 4 specification.
 WordPerfect 5.1 requires a TIFF 4 preview.
 A TIFF 6 preview is a Baseline Bilevel Image,
 or a Baseline Palette-colour Image (4 or 8 bits/pixel)
 or a Baseline RGB Full Colour Image (24 bits/pixel)
 according to the TIFF 6.0 specification.
 TIFF 6 previews are either uncompressed or compressed with packbits.
 A Windows Metafile preview contains an uncompressed bitmap.

 7.
 Reset `Orientation` | `Portrait`, and
 `Media `| `Display Settings` to their previous values.

 To extract the PostScript or Preview section from a DOS EPS
 file, use `File` | `Select File` followed by `Edit `| `Extract EPS`
 then `PostScript` or `Preview`.

 See also `PS to EPS`.
3User Supplied Preview
-User_Supplied_Preview
?User Supplied Preview
 The `Edit `| `Add EPS Preview` | `User Supplied Preview` command
 allows an existing TIFF or WMF file to be added to an EPS file
 to create a DOS EPS file.
 This is useful if an application can export to an EPS file and to
 a WMF file, but cannot create a DOS EPS file with a WMF preview.
 The EPS file `must` contain a bounding box that corresponds with
 the TIFF or WMF preview file.
 It is not necessary to display the EPS file. `User Supplied Preview`
 can be used after an EPS file has been opened with `Select File`.

 You can add a preview that has no resemblance to the PostScript,
 which is most undesirable.
WP
3Convert to vector format
-PStoEdit
?Convert to vector format
?PStoEdit
 You can convert a PostScript or PDF file to an editable vector
 format using `pstoedit` by Wolfgang Glunz.
 `pstoedit` is licensed with the GNU Public Licence and is not
 included with GSview.  You will need to download it separately
 from the pstoedit homepage
  http://www.pstoedit.net/pstoedit
 or from
  http://www.cs.wisc.edu/~ghost/gsview/pstoedit.htm

 To use `pstoedit` from within GSview, use
 `Edit | Convert to vector format`.
 Three dialog boxes will be shown.

 The first dialog is for pstoedit settings.

 Select an output `Format`.

 `Draw text as polygons` should be selected if the PostScript file
 contains text and the output format does not support this, e.g. gnuplot.
 This might produce a large output file.

 When `Map to ISO-Latin1` is selected, pstoedit maps all character codes
 to the ones defined by the ISO-Latin1 encoding, which is used by
 HTML and MS-Windows.  This is the default.
 If you uncheck this item, the encoding from the input PostScript
 is passed unchanged to the output.

 If the output format does not support curves in the way PostScript
 does, all curves are approximated by lines. The `Flatness` option
 is used to control this approximation. This parameter is directly
 converted to a PostScript setflat command. Small values produce
 a more accurate approximation, but more line segments.

 Sometimes fonts embedded in a PostScript program do not have a
 fontname. For example, this happens in PostScript files generated
 by dvips. In such a case pstoedit uses a replacement font.
 The default for this is Courier.  Another font can be specified
 using the `Default Font` option.
 Some alternative font names are Courier, Helvetica and Times-Roman.

 Some of the output formats support extra options.  See the pstoedit
 manual for more details.  For example, the java output format
 uses `Driver Options` to specify the name of the java class.

 The second dialog (omitted if no page numbering is available)
 specifies the page to be converted, or if supported by the output
 format, a range of pages to be converted.

 The third dialog specifies the output file name.

 Not all `pstoedit` formats support bitmap graphics.
 If you need bitmap output, see `File conversions and tricks`.

 For more details please read the pstoedit manual.

 In general, extracting text from a PostScript document is not a
 trivial operation.  Words may be broken.  Text may be encoded.
 Ligatures may be used (e.g. replacing 'fi' with a single character).
 There may be no relationship between the location of a word in
 the PostScript file and its location on the page.
 Success in extracting text from a PostScript document depends
 greatly on the document itself.

 GSview has two methods of extracting text from a PostScript file.

 The quick method extracts all text from PostScript strings.

 The second method uses pstotext and Ghostscript to more accurately
 extract text from a PostScript document.

 The method used is selected by `Options` | `PStoText`.
 See the appropriate topic below:

 See also `Conversions`.
4Quick Text Extract and Find
-Quick_Text_Extract_and_Find
?Quick Text Extract and Find
 It is common for PostScript documents to contain text in the
 same order as it appears on the page, and for it to be given in
 PostScript strings, surrounded by parentheses.  Complete lines
 may be given in one string, or one word per string.  For this sort
 of document, extracting text can be done with reasonable success.

 `Edit `| `Text Extract` will extract text contained in strings from
 specified pages and write it to a text file.
 Line breaks in this text file correspond to lines in the document.
 Spaces in the text file correspond to spaces within strings, or to
 separate strings.  A more effective method of extracting text is to
 use ps2ascii.ps supplied with Ghostscript, or to use the `PStoText`
 program listed on the Ghostscript `WWW` page.  `PStoText` can be
 used from GSview by using `Options` | `PStoText`.

 `Edit `| `Find` will search for text and display the first
 page that contains the text.  `Find` asks for a search text
 and a range of pages in which to search.
 The preceding comments about extracting text from a PostScript
 document should be noted.  `Find` first extracts text from
 the document, then searches it ignoring all spaces in both the
 document and the search text.  Case is ignored when searching.
 Consequently the search text `these` would match both `These`
 and `The serial`.  No information is given about where the word
 is located on a given page because this information is not
 available without a complete PostScript interpreter.
 `Find` will not work for non DSC documents or DSC documents with
 special page order.

 `Edit `| `Find Next` will continue the search from the next page.
4PStoText Text Extract and Find
-PStoText_Text_Extract_and_Find
?PStoText Text Extract and Find
 This method uses pstotext and Ghostscript to extract text from
 a PostScript document.  Before doing any text extraction or
 searching, the entire PostScript document will be processed by
 Ghostscript and pstotext to produce a text index file.
 This may take a long time.  Once this has finished, text extraction
 and searching should be quick.

 pstotext uses the ISO-Latin1 character set.  See the pstotext
 documentation for more details.
  http://www.research.digital.com/SRC/virtualpaper/pstotext.html

 `Orientation` must be set to match the text direction of the
 document.

 `Edit `| `Text Extract` will extract text from specified pages
 and write it to a text file.

 Words can be copied to the clipboard using` Edit` | `Copy`.

 `Edit `| `Find` will search for text and display the first
 page that contains the text.  `Find` asks for a search text
 and a range of pages in which to search.
 The search text is first broken up into words.  For each search word,
 a search is made to find a match anywhere within a document word.
 Searching for` frog` would find` frog`,` frogs` and` bullfrogs`.
 The wildcards '*' (zero or more characters) and '?' (any one character)
 are supported, but it doesn't make sense to use them at the beginning
 or end of a word.
 Wildcards do not extend beyond the word being searched.
 Multiple complete words may be specified, e.g.  `GSview is a`.
 If the search text is found, the page containing the text is displayed
 and the first word highlighted.
 `Find` will not work for non DSC documents or DSC documents with
 special page order.

 `Edit `| `Find Next` will continue the search.

 For most PostScript files you should use
 `Options` | `PStoText` | `Normal`.

 `Options` | `PStoText` | `Dvips Cork Encoding`
 is only relevant for PostScript files produced by
 dvips from TeX or LaTeX documents; it tells `pstotext` to use the
 Cork encoding rather than the old TeX text encoding. Unfortunately
 files produced by dvips don't distinguish which font encodings were
 used.
3Clipboard
-Clipboard
?Clipboard
?Copy
?Paste To
?Convert Bitmap
?Bitmap
WP
 The GSview window can be copied to the Clipboard as a bitmap
 by selecting `Copy` from the `Edit` menu.
 The bitmap will be a Device Independent Bitmap (DIB/BMP format).

 An alternative way to get a bitmap output from Ghostscript is
 to use one of the BMP drivers.  See `Print`.

W
 `Paste To` copies a Device Independent Bitmap from the Clipboard
 (if available) to a BMP file.

 `Convert Bitmap` converts between a Device Independent Bitmap and
 a Device Dependent Bitmap.
 If the clipboard contains a Device Independent Bitmap (BMP format),
 this is converted to a Device Dependent Bitmap and added to the clipboard.
 If the clipboard does not contain a colour palette, one is created
 from the Device Independent Bitmap and added to the clipboard.
 This option is present because some applications (notably Windows
 Paintbrush) won't recognise a Device Independent Bitmap in the clipboard.
P
 `Paste To` copies the currently displayed image (if available)
 to a BMP file.
X
 There are no clipboard operations implemented in the X11 GSview.

 `Save Image as BMP` will save the currently displayed page
 as a Windows bitmap.
E

 If `Text Extract` or `Find` are used on a document with `PStoText` enabled,
 GSview creates an index of the words in the document.  If any words are
 marked with the mouse,
WP
 `Copy` will copy these words to the clipboard instead
 of copying a bitmap.
X
 these will become the current X selection.
E
 Text cannot be marked until either `Text Extract`
 or `Find` has been used with `Options` | `PStoText` enabled.
2Measure
-Measure
?Measure
?Calculate Transformed Units
 Lengths can be measured using the cursor location displayed on
 the status bar, or with the `Edit |` `Measure` dialog box.

 This dialog box shows the start location, finish location,
 difference between these locations and the length and angle
 between these locations.
 The start location is set when you click the left mouse button.
 The default start location is the lower left corner of the page.
 The units can be pt, mm, inch, or custom.

 Custom units allows you to display coordinates as they appear
 in a PostScript file.
 Custom units are usually specified by starting with an identity
 matrix and then performing a series of transformations.
 If a PostScript file invokes landscape orientation using
  90 rotate
  0 -595 translate
 then to display the user coordinates you would enter
 the following in the Calculate Transformation dialog:
  Custom
  initmatrix
  90 rotate
  0 -595 translate
  invertmatrix
  Ok
 The Current Transformation Matrix (CTM) is shown in
 upper part of the dialog.  You can enter a CTM directly
 if you like maths.
 It is easier to enter values in the Custom edit fields below this,
 but these have no effect until one of the transform buttons
 (translate, rotate, scale) is selected.

 See also `Units`.
2Options
-Options
?Options
 The `Options` menu has the following selections:
3Easy Configure
-Easy_Configure
?Easy Configure
W
 Easy configure allows you to select which version of
 Ghostscript to use.  It is assumed that you have already installed
 AFPL Ghostscript 7.04 or later.
 If you do not have Ghostscript installed, see the topic
 `Obtaining Ghostscript`.
 For more control over configuration of GSview, see
 `Advanced Configure`.

 Easy configure will set the correct paths for Ghostscript
 and copy some printer defaults to the INI file.
 It does not alter the registry or start menu.
P
 Easy configure starts a configuration wizard to select the
 Ghostscript version and file associations.
E
3Advanced Configure
-Advanced_Configure
?Advanced Configure
?Ghostscript DLL
?Ghostscript Include Path
?Ghostscript Options
X
 `Ghostscript Version` tells GSview which version of Ghostscript
 is being used.  5.50 should be entered as 550, 6.50 as 650.

 `Ghostscript EXE` tells GSview where to find Ghostscript.
 The default is `gs`.
WP
 `Ghostscript DLL` tells GSview where to find Ghostscript.
W
 The default for Win32 is
  c:\gs\gsN.NN\bin\gsdll32.dll
P
 The default for OS/2 is
  c:\gs\gsN.NN\bin\gsdll2.dll
E

 Enter the correct Ghostscript include path into the
 `Ghostscript Include Path` field.
 This include path must include the directories where the Ghostscript
 library files (gs_*.ps and Fontmap) and the Ghostscript fonts (*.pfb)
 are located. For example:
P
   c:\gs\gsN.NN\lib;c:\gs\fonts;c:\psfonts
W
   c:\gs\gsN.NN\lib;c:\gs\fonts
X
   /usr/share/ghostscript/6.0;/usr/share/ghostscript/fonts
 The default is blank.
E
 Do NOT put a `-I` before the include path.

 The `Ghostscript Options` field may be empty.
 If you wish to turn off the `Platform Fonts` feature under
 MS-Windows, put `-dNOPLATFONTS` in the `Ghostscript Options` field.
 If you wish to search for fonts not listed in Fontmap,
 add -sFONTPATH to this field.  For example
   -dNOPLATFONTS -sFONTPATH="c:\psfonts"

 If you do not get the `Ghostscript DLL` field correct, GSview will
 not be able to load Ghostscript.
 If you do not get the `Ghostscript Include Path` correct, Ghostscript
 will not initialise and will then unload.
W

 Selecting `Copy printer defaults` will update gsview32.ini from the
 file printer.ini.

 Selecting `Associate .ps files with GSview` will update the registry
 to associate PostScript files with GSview.

 Selecting `Associate .pdf files with GSview` will update the registry
 to associate Portable Document Format files with GSview.

 Selecting `Create Start Menu items` will add GSview to the start menu.

 There is no undo facility for the actions of these four checkboxes.
 The Associate and Start Menu actions are normally performed
 (with an undo facility) by the GSview setup program.
E

 See the `Installation` topic.
WP
3Sounds
-Sounds
?Sounds
 The `Sounds` option assigns sounds to various events.
 For each event the sound can be set to `None`, a `Speaker Beep` or
 a `Wave` file.

 You must have a sound driver loaded before using Wave files.
 Wave file sounds are not available under MS-Windows 3.0.

 The events are:

 `Output Page`: the PostScript showpage operator was executed.

 `No Page`: an invalid page was selected.
 For example, pressing `Prev` while on the first page of a document
 with `DSC` comments.

 `No Number`: a command required page numbering and the document did
 not have page numbering.
 For example, pressing `Goto Page` when viewing a document without
 `DSC` comments.

 `Not Open`:  a command required a document to be open and this was
 not the case.
 For example, pressing `Goto Page` when no document is open.

 `Error`: many types of errors.

 `Start`: GSview opened.

 `Exit`: GSview closed.

 `Busy`: busy at the moment, can't do what you asked.

 The defaults are for `No Page`, `Error` and `Busy` to be a
 `Speaker Beep` and all other events to be `None`.
E
3Units
-Units
?Units
 The `Units` option sets the units used to display the cursor location
 on the status bar.  Available units are PostScript points (`pt` = 1/72"),
 millimetres (`mm`) and inches (`in`).
 The default is `pt`.

 The resolution of the units can be increased by selecting
 `Units `| `Fine Resolution`.

 See also `Measure`.
3Language
-Language
?Language
?International
 GSview is available in English, Dutch, French, German, Greek,
 Italian and Spanish.
 To change the language use `Options` | `Language`.

 On Windows NT, all existing languages are available to be
 selected, independent of the regional settings.
 On other systems, the language availability depends on the
 selected regional settings, in particular the chosen locale
 or system code page.
3PStoText
-PStoText
?PStoText
 GSview has two methods of extracting and searching text.

 The `Quick Text Extract and Find` method does a simple extraction
 of PostScript strings.  This method is easily confused.
 This is selected by the menu item `PStoText` | `Disabled`.

 The `PStoText Text Extract and Find` method uses the external pstotext
 tool and Ghostscript to extract words and their co-ordinates.
 This method is more accurate, but there may be a long pause while
 pstotext and Ghostscript do the initial processing.
 After this, text extraction and searching should be quick.
 There are two modes of operation.  `Normal` should be used
 for most PostScript files.  `Dvips Cork Encoding` should be
 used if you have a PostScript file produced by dvips
 which uses Cork Encoding.

 The default is `Normal`.
3DSC Warnings
-DSC_Warnings
?DSC Warnings
 Some documents contain errors in the Document Structuring Conventions.
 The level of warnings provided by GSview can be set using
 `Options` | `DSC Warnings`.
 If set to` Off`, GSview will assume that the DSC comments are correct.
 `Errors` will notify you of errors in the DSC comments .
 `Warnings` will notify you of warnings and errors in the DSC comments.
 `All` will notify you of irregularities, warnings and errors in the
 DSC comments.  The default is `Warnings`.

 If you ask to be notified about errors and warnings, the DSC
 warning dialog box allows you to make the following choices:
 `OK` tells GSview to take a guess about what was probably meant
 (rather than what the DSC comment actually said),
 `Cancel` tells GSview to treat the DSC as being correct,
 `Ignore DSC ` tells GSview to ignore all DSC comments.

 If `DSC Warnings` is` Off`, GSview will assume `Cancel`.
 Documents with incorrect DSC comments will be likely to cause problems.
3Save Settings
-Save_Settings
?Save Settings
?Save Settings Now
?Save Settings on Exit
?Settings
?INI file
 The `Save Settings Now` option saves the GSview window position,
 window size, last used printer, last directory,
 all items on the `Options` menu and all items on the `Media` menu
 to the initialisation file
W
 gsview32.ini in the Windows system directory (or for Windows
 95 or NT 4 in the user profile directory if user profiles are
 being used).
P
 gvpm.ini in the OS/2 system directory.
X
 .gsview.ini in your home directory.
E
 GSview reads this file during startup.

 When the `Save Settings on Exit` option is checked, GSview will
 automatically save the above settings when you quit GSview.
3Safer
-Safer
?Safer
 When the `Safer` option is `checked`, GSview will give Ghostscript
 the `-dSAFER` flag, which disables the deletefile and renamefile operators,
 and the ability to open files in any mode other than read-only.
 This is the default.

 When the `Safer` option is `unchecked` Ghostscript can change
 files.
3Save Last Directory
-Save_Last_Directory
?Save Last Directory
 When the `Save Last Directory` option is `checked`, GSview will
 save the current directory when you quit GSview.  When GSview
 is started next, this will be made the current directory.
 This is the default.

 When `Save Last Directory` option is `unchecked`, the current
 directory when GSview is started will be the current directory
 of the program that started GSview.
3Button Bar
-Button_Bar
?Button Bar
?Magnify
 When the `Button Bar` option is `checked`, GSview will display
 a Button Bar
WX
 at the top
P
 down the left side
E
 of the window.  This is the default.
 The Button Bar contains the following items in order from
WX
 left to right:
P
 top to bottom:

E
 `Edit `| `Find Next`

 If using the increase/decrease resolution buttons, `Auto Redisplay`
 should be set.  Instead of using these buttons the
 `Media `| `Display Settings` command can be used.
 When the `Button Bar` option is `unchecked`, GSview will not
 display the Button Bar.
WP
3Fit Window To Page
-Fit_Window_To_Page
?Fit Window To Page
 When the `Fit Window To Page` option is `checked`, changes to the page
 size or orientation will cause the window size to be enlarged or
 reduced to suit the page size.
 Whenever the window is resized, GSview will force it to be no larger
 than the page being displayed.

 Changes in the window size will only occur when the window is resized
 or the page size changed; it does not happen immediately after this
 option is changed.
 Fit Window To Page is ignored for a maximized window.

 If `Fit Window To Page` is `unchecked`, GSview will not resize the
 window and areas outside the page will be drawn in light grey.
 This is useful if you do not wish the window to shrink when looking
 at pages at low resolution.  This is the default.

 See also `View` | `Fit Window`.
E
3Auto Redisplay
-Auto_Redisplay
?Auto Redisplay
 When the `Auto Redisplay` option is `checked`, GSview will
 redisplay `DSC` documents when the `Orientation`, `Resolution`,
 `Depth` or `Media` are changed.
 This is the default.

 For `non-DSC documents`, if `Auto Redisplay` is `checked`,
 GSview will `restart at the first page`.

 If `Auto Redisplay` is `unchecked`, the `View` | `Redisplay` command
 must be used to redisplay a document after changing the
 `Orientation`, `Resolution`, `Depth` or `Media`.
3EPS Clip
-EPS_Clip
?EPS Clip
?PDF Crop
 When the `EPS Clip` option is `checked`, GSview will clip the
 display bitmap to the bounding box of an EPS file instead of using the
 page size specified on the `Media` menu.  This is useful when
 adding a bitmap preview to an EPS file.
 If a PDF file is being displayed, `EPS Clip` will cause the
 display to be clipped to the PDF crop box.

 If `EPS Clip` is `unchecked`, GSview will use the page size
 specified on the `Media` menu for EPS files.  This is the default.

 `EPS Clip` does not alter the original document, it only affects
 how much of the document is displayed by GSview.
 It does not affect printing.

 See also `Edit `| `Add EPS Preview`
3EPS Warn
-EPS_Warn
?EPS Warn
 When the `EPS Warn` option is `checked`, GSview will write a
 prolog to Ghostscript when each file is opened.  This prolog will
 produce warning messages in the `File `| `Show Messages`
 window if any PostScript operators that should not be used in `EPS`
 files are used.  An example warning message is:
  Warning: EPS files must not use /initgraphics
 `EPS Warn` is not infallible.  It is possible to access restricted
 operators without `EPS Warn` producing a warning.
 If you do get a warning, do NOT used `PS to EPS`.

 The default for `EPS Warn` is `unchecked`.

 See also `PS to EPS`.
3Ignore DSC
-Ignore_DSC
?Ignore DSC
 Some documents incorrectly claim to conform to the Adobe Document
 Structuring Conventions.  Attempting to display one of these bogus
 documents will probably leave GSview horribly confused and unable
 to display the document.  If `Ignore DSC` is `checked`, GSview
 will treat the document as if it does not contain DSC comments
 and will only display the pages in the original order.

 The default for `Ignore DSC` is `unchecked`.
3Show Bounding Box
-Show_Bounding_Box
?Show Bounding Box
 Selecting this option causes a dashed rectangle to drawn over
 the image, showing the location of the bounding box.
 This bounding box is only drawn on the display, and does not
 affect printer output.
 The bounding box will only be shown for `DSC` documents (non
 conforming documents don't have a bounding box).

 The default for `Show Bounding Box` is `unchecked`.
2Page Orientation
-Page_Orientation
?Auto Orientation
?Orientation
?Portrait
?Landscape
?Upside-down
?Seascape
?Swap Landscape
 The `Portrait`, `Landscape`, `Upside-down` and `Seascape`
 (reverse Landscape) commands on the `Orientation `Menu select
 the page orientation used by the display.
 `Landscape` implies a clockwise rotation of the paper by 90 degrees.
 `Seascape` implies an anti-clockwise rotation of the paper by 90 degrees.
 These orientation options only affect the display and do not affect
 the print commands.

 If the `Auto` command on the orientation menu is checked and
 a `DSC` page orientation comment is found (%%Orientation or
 %%PageOrientation), the orientation will be selected automatically.

 When the `Swap Landscape` option is `checked`, GSview swaps the
 meaning of Landscape and Seascape.
 Most of the Landscape documents that I have encountered require a 90
 clockwise rotation of the paper to view.
 However, there is no standard and some documents need to be rotated
 the other way.
 The `Swap Landscape` button allows GSview to automatically rotate the
 document the right way in response to the `%%Orientation` comment in the
 PostScript file.

 See also `Page Size` and `Display Settings`.
2Display Settings
-Display_Settings
?Display Settings
?Resolution
?Zoom Resolution
?Depth
?Alpha
?Anti-aliasing
?TextAlphaBits
?GraphicsAlphaBits
?Draw Method
 Some settings for display only can be set with `Media` | `Display Settings`.

 The `Resolution` field sets the display resolution in dots per inch.
 The default for a VGA display is 96 dots per inch.
 This can also be changed by the resolution changing buttons on
 the button bar.

 For DSC conforming files, pressing the right mouse button will
 `Zoom` into the page at what is usually printer resolution.
 Pressing the right mouse button a second time will zoom back out to
 normal display resolution.
 The `Zoom Resolution` field sets the zoom resolution in dots per inch.

 The `Depth` field sets the page bitmap depth in bits per pixels
 for the display.
 Default will select the highest depth supported by your display
 driver.  In general, you shouldn't set this higher than your
 actual display depth because doing so will use extra memory
 for the page bitmap but won't improve the display.

 The `Text Alpha` field sets anti-aliasing for fonts.  The default
 (use anti-aliasing) is 4 bits.  To disable anti-aliasing of fonts,
 use 1 bit.
W

 `IMPORTANT`: If you use `Text Alpha`, GSview will disable
 `Platform Fonts` by doing the equivalent of adding
   -dNOPLATFONTS
 to the `Options `| `Advanced Configure` Ghostscript Options field.
E

 The `Graphics Alpha` field sets anti-aliasing for graphics and
 also for text that is too large to fit in the font cache.

 Using anti-aliasing slows down drawing.
 Text and Graphics Alpha can only be used if your display depth is
 set to 8bits/pixel or higher.
P

 A number of buggy display drivers have been written for OS/2.
 Many of these have a non-functional GpiDrawBits() API.
 The default `Draw Method` is to use GpiDrawBits() for most
 displays, and a slower double buffering method using
 WinDrawBitmap for VGA (4bit/pixel) displays.

 If your display has problems drawing the bitmap (usually
 seen during scrolling) or a SYS3175 (memory access violation)
 occurs in the display driver, then try explicitly using the
 GpiDrawBits or WinDrawBitmap method.

 If you have bugs in your display driver, please complain to
 the company that wrote it.
E
3Zoom
-Zoom
?Zoom
 To enlarge a displayed feature, position the cross-hair mouse pointer
 over the feature then press the right mouse button.
 The window will swap from normal display resolution to zoom
 resolution and the status line will have the word `Zoomed` appended to it.
 The zoomed feature will be in the centre of the window.
 To cancel `Zoom`, press the right mouse button again or select
 any command that redraws the page (e.g. `Redisplay`, `Next Page`).
 By default the zoom resolution is 300 dots per inch but this can
 be changed with `Media` | `Display Settings` dialog box.

 `Zoom` will only work for `DSC` conforming documents.

 To enlarge or shrink the entire page, use the `Resolution`
 on the `Media` | `Display Settings` dialog box, use the magnifying
 glass toolbar buttons.
2Page Size
-Page_Size
?Page Size
?Media
?User Defined
?Rotate Media
 The `Media` menu also allows selection of page size.
 Available page sizes are:
  11x17          11   x 17   inch
  A0              840 x 1189 mm
  A1              594 x 840  mm
  A2              420 x 594  mm
  A3              297 x 420  mm
  A4              210 x 297  mm
  A5              148 x 210  mm
  B4              257 x 364  mm
  B5              182 x 257  mm
  Ledger         17   x 11   inch
  Letter          8.5 x 11   inch
  Legal           8.5 x 14   inch
  Note            8.5 x 11   inch

 A user defined size can be specified in PostScript points (1/72 inch)
 with the `User Defined` command.  A size of 480x360 points at 96 dpi
 will give an image size of 640x480 pixels.

 If a `DSC` media comment is found, such as
  %%DocumentPaperSizes: a4
  %%DocumentMedia: a4 595 842 80 white ( )
 the page type will be selected automatically.
 If the media specification is not one of the above page types,
 the `User Defined` size will be set.

 If `Rotate Media` is checked, the width and height of the page
 are exchanged.  The image drawn on the page is not rotated.
 This affects both display and printing.
 Selecting `A4` and `Rotate Media` is equivalent to selecting
 `User Defined` with a size of 842 x 595 pt.
 It is more common to use the settings on the `Orientation` menu
 than `Rotate Media`.

2Command line options
-Command_line_options
?Command line options
 GSview ignores the case of options:
 -p is the same as -P.  On Windows or OS/2, you can also
 use /p or /P.  In the samples below, replace `gsview` with
 `gsview32` on Windows and `gvpm` on OS/2.

 Usage:
  gsview [-d] [-t] [-f[DEVICE]] [-p[QUEUE]]
    [-mPAPERSIZE] [-oORIENTATION] [-rXDPIxYDPI]
    [-geometry WIDTHxHEIGHT[+XOFF+YOFF]] filename

 Options:

 `filename` To start GSview and display filename.ps:
  gsview filename.ps

 `-p` prints filename.ps using Ghostscript.
 This is similar to `File` | `Print`, except that you will
 not be prompted for a printer (it will use the printer most
 recently used by GSview, or the printer name you provide)
 and GSview will exit after printing has finished:
  gsview -p filename.ps

 `-f` converts a PostScript file (not PDF) filename.ps
 to a file using Ghostscript (`File` | `Convert`):
  gsview -f filename.ps

 `-m`PAPERSIZE sets the paper size.  Any of the predefined
 sizes on the media menu are valid.

 `-o`ORIENTATION sets the orientation and may be one of
 `auto`, `portrait`, `landscape`, `upsidedown` or `seascape`.

 `-r`XDPIxYDPI sets the display, convert or print resolution.

 To display a file with A4 paper, landscape orientation
 and 96dpi:
  gsview -ma4 -olandscape -r96x96 filename.ps

 `-d` Debug mode.
 In debug mode GSview will `not` remove its temporary files.
 This is to allow inspection of these files after GSview has finished.
 Debug mode also produces more verbose output for `File `| `Show Messages`.
 To write debugging output to
WP
 c:\gsview.txt
X
 standard output
E
 use -d9

 `-t` Multi-threading.  GSview by default runs multi-threaded,
 except for Windows 3.1/Win32s.
 To change this, use `-t` to toggle the threading mode, use `-t0` to select
 single-thread mode and `-t1` to select multi-thread mode.

W
 Windows supports a few additional command line options.

 `-s` spools a file directly to the printer, without using Ghostscript.
 GSview will exit when the file has been spooled.
 Some examples are:
  gsview -s filename.ps
  gsview -sLPT3: filename.ps
  gsview -s"HP DeskJet Portable" filename.ps

 `-e` uses DDE to open a file in an existing GSview, or if GSview
 is not already running, in a new window using.
  gsview -e filename

 `-x` uses DDE to tell an existing GSview to close.
  gsview -x
X
 On GNU/Linux you an also use:
  gsview -v     (display version)
  gsview -h     (display help)

3Dynamic Data Exchange
-Dynamic_Data_Exchange
?Dynamic Data Exchange
?DDE
 GSview implements a DDE server, service="GSview and topic="GSview".
 The XTYP_EXECUTE commands that are recognised are:
  [FileOpen("filename")]
  [FileExit()]
  [NextPage()]
  [PrevPage()]
  [GoBack()]
  [GotoPage(5)]
  [ShowWindow(nCmdShow)]
  [Minimise()]
  [Maximise()]
  [Command("command line")]
 The [Command()] command only understands "filename" or "/P filename".

 Don't sent multiple commands together.  GSview won't complain,
 but the multithreaded asynchrononous execution within GSview
 means that the first command won't have been completed before
 the second command is received.  If you need to send multiple
 commands, send them separately with pauses inbetween.

 There are two command line options to cause GSview to send a DDE
 command to another copy of GSview.
 The /E command line option uses [Command("command line")][ShowWindow(1)].
 The /X command line option uses [FileExit()].

 `Problem:` Can't load Ghostscript DLL ...

 GSview requires the Ghostscript DLL
 (gsdll2.dll for OS/2, gsdll32.dll for Win32).
 This error message usually occurs if you don't have Ghostscript,
 or if GSview can't find Ghostscript.

 From the GSview menu select `Options` | `Advanced Configure`
 and enter the correct `Ghostscript DLL` path. For example
P
  c:\gs\gsN.NN\bin\gsdll2.dll
W
  c:\gs\gsN.NN\bin\gsdll32.dll
WP

 This message also occurs if Ghostscript cannot find its
 initialisation files (e.g. gs_init.ps).  Set the
 `Ghostscript Include Path` correctly.

W
 If using Win32s, make sure you don't already have a copy of
 the Ghostscript DLL loaded by another copy of GSview.
 Only one copy of Ghostscript DLL can be loaded by Win32s at a time.

WP
 If you can't get GSview to run Ghostscript DLL correctly, make sure
 you can configure and run Ghostscript on its own.

 `Problem:` Ghostscript Messages window says
 `Can't find initialization file gs_init.ps`.

 Set the `Ghostscript Include Path` to point to the directory containing
 the correct gs_init.ps.

 `Problem:` Ghostscript Messages window says
 `gs: Interpreter revision (XXX) does not match gs_init.ps revision (YYY)`.

 Set the `Ghostscript Include Path` to point to the directory containing
 the correct gs_init.ps.
 Don't try to display a PostScript file in the directory of an old
 version of Ghostscript (which will cause the old gs_init.ps to be
 loaded irrespective of the `Ghostscript Include Path`).

 `Problem:` Ghostscript Messages window says
 `Wrong version of DLL found.  Found version XXX  Need version YYY`.

 GSview found the wrong Ghostscript DLL.  Install the required
 version of the Ghostscript DLL.  Make sure you have only one copy
 of the Ghostscript DLL on your system.

E
 `Problem:` GSview says that a multipage PostScript file produced
 by MS-Windows contains 0 pages and will only show the first page.

 This is because the document does not have correct DSC comments.
 From the Control Panel, select `Printers`, `Options...`, then in the
 `Print to` group box click on the `Printer` radio button.  You cannot
 use the `Print To` `Encapsulated PostScript File` for printing
 multipage files.  The correct method is to connect the printer
 to `FILE:`.
 In addition,
 from the Control Panel select `Printers`, `Options...`, `Advanced` and
 then check `Conform to Adobe Document Structuring Convention`.

 The DSC comment `%%Pages: 0` means that the document does not produce
 any pages.  That is, the PostScript `showpage` operator is not used.
 If you find a PostScript document that has multiple pages and contains
 the `%%Pages: 0` comment, change the first line from `%!PS-Adobe-` to `%!`.
 GSview will then ignore the DSC comments and allow you to view all
 pages, but only in the original order.  Complain to the author of the
 program that produced that PostScript file.

 Some PostScript printer drivers include code that is specific to
 a particular printer.  The PostScript output from these drivers may
 be unportable and may not display in GSview.  If you are having this
 problem, try using a reasonably generic PostScript driver such as
 `Apple LaserWriter II NT` for PostScript level 2 printers, or
 `Apple LaserWriter Plus` for PostScript level 1 printers.

 For Windows 95, open the printer properties then select the
 PostScript tab, then select PostScript Output Format =
 `PostScript (optimize for portability - ADSC)`.

 `Problem:` GSview says "Page ordering is Special..."

 Your document used the DSC comment `%%PageOrder: Special` which means
 that pages can not be reliably reordered.  This may prevent GSview
 from displaying pages in any order other than the original order.
 If you continue and reorder the pages, PostScript errors may occur.
 The only way to fix this is to regenerate the PostScript without
 special page ordering.

 By default, Windows 95 creates PostScript files which use special
 page ordering.  To disable this, open the printer properties then
 select the PostScript tab, then select PostScript Output Format =
 `PostScript (optimize for portability - ADSC)`.

 `Problem:` PostScript files produced by MS-Windows start with a Control-D.

 For Windows 3.1:

 Since this occurs even when the PostScript printer
 `Conform to Document Structuring Convention`
 checkbox is checked, this must be considered a
 bug in the MS-Windows PostScript printer driver.
 The bug fix is documented in the MS-Windows PRINTERS.WRI file.
 Edit the win.ini file and search for the PostScript printer section.
 There may be more than one.  In each of these sections add
 `CTRLD=0` as shown below.

  [Apple LaserWriter II NT,FILE]
  CTRLD=0

 For Windows 95:

 The PostScript printer driver setup has an option
 (Properties, PostScript, Advanced) for suppressing
 a ^D at the start of a document.
 Fortunately the default is do not send ^D before job.

 `Problem:` PostScript files produced by Word for Windows 6.0
 cause a "Missing %%Pages comment" message box.

 Congratulations.  You have just found a mistake in the DSC comments
 when Word included an EPS file.  Word should have surrounded the
 included EPS file with the lines
  %%BeginDocument: filename.eps
  %%EndDocument
 Because Word didn't do this, GSview can't tell how many pages
 are in the document and where they are located.

 Please complain to Microsoft.  There is a problem in the EPSIMP.FLT
 filter version 2.01 which Microsoft needs to fix.

 In the interim, you have two solutions:

 1. Select `Options` | `Ignore DSC`

 2. Edit the PostScript file to correct the DSC comments.
 Search the PostScript file for all lines containing
   %MSEPS Preamble
 From each of these lines, search forward for the start of the
 included EPS file which should start with a line like
  %!PS-Adobe-3.0 EPSF-3.0
 Above these lines add the line
  %%BeginDocument: AddedByHand

 Then search for all lines containing
  %MSEPS Trailer
 Above these lines add the line
  %%EndDocument

 GSview should then be able to display the file correctly.

 `Problem:` GSview doesn't recognise the DSC comments in files
 produced using the Adobe PostScript driver 4.10 for Windows 32-bit.

 Do not use Tagged binary communications protocol.
 Change this to "Printers | PostScript tab | Advanced... |
 Data format group box | ASCII data"

 `Problem:` Trying to open any file gives
  `Unrecoverable error: configurationerror in setpagedevice`
  Failed to open device or install ViewerPreProcess hook: returns -26
  Page size may have been too large or resolution too high.
  Resetting page size and resolution

 Either the problem described in the error message has occurred,
 in which case you should reduce the page size, resolution,
 depth or a combination of all three.
 Alternatively, you may have used `-dFIXEDMEDIA` in the Ghostscript
 environment variable GS_OPTIONS.  When using GSview, it is safest
 not to use GS_OPTIONS at all and to use `Options` |
 `Advanced Configure` | `Ghostscript Options` instead.

 `Problem:` GSview hangs or takes a very long time when displaying a file.

 Resolution may have been set too high or page size too large.
 Reduce the resolution to the default 96dpi using
 `Media `| `Display Settings`.
 Change the page size with the `Media` menu.

3Internals
-Internals
?Internals
WP
 GSview uses the AFPL Ghostscript DLL to render PostScript files.

 Under Win32s, the GS DLL can be used by only one application at a
 time.  Under Windows 95, Windows NT and OS/2, the GS DLL can be used
 by many applications at a time (provided you have enough memory).
 When using Win32s, GSview must unload the GS DLL while it is being
 used by gvwgs.exe for printing.

 gsv16spl.exe is a 16 bit Windows application used by GSview to spool
 files from GSview Win32s.  gsv16spl can not be used on its own - it
 must be started by GSview.  It is not used by Windows 95 or NT.

 gvwgs32.exe (Windows) and gvpgs.exe (OS/2) are GS DLL loaders for
 printing.  It would be possible to use them from the command line,
 but since they delete the files listed on the command line
 it would be safer to use gswin32.exe (Win32), gswin32c.exe
 (Win32 console) or gsos2.exe (OS/2).
