 PdfDictionary newDic,
 PdfReader reader)

PRStream

PRStream(PdfReader reader,
 int offset)

PRStream

PRStream(PdfReader reader,
 byte[] conts,
 int compressionLevel)

Creates a new PDF stream object that will replace a stream in a existing PDF file.

Parameters:

reader - the reader that holds the existing PDF

conts - the new content

compressionLevel - the compression level for the content

Since:

2.1.3 (replacing the existing constructor without param compressionLevel)

Method Details

setData

private void setData(byte[] data,
 boolean compress)

Sets the data associated with the stream, either compressed or uncompressed. Note that the data will never be compressed if Document.compress is set to false.

Parameters:

data - raw data, decrypted and uncompressed.

compress - true if you want the stream to be compressed.

Since:

iText 2.1.1

setData

private void setData(byte[] data,
 boolean compress,
 int compressionLevel)

Sets the data associated with the stream, either compressed or uncompressed. Note that the data will never be compressed if Document.compress is set to false.

Parameters:

data - raw data, decrypted and uncompressed.

compress - true if you want the stream to be compressed.

compressionLevel - a value between -1 and 9 (ignored if compress == false)

Since:

iText 2.1.3

setData

public void setData(byte[] data)

Sets the data associated with the stream

Parameters:

data - raw data, decrypted and uncompressed.

setLength

public void setLength(int length)

getOffset

public int getOffset()

getLength

public int getLength()

getReader

public PdfReader getReader()

getBytes

public byte[] getBytes()

Description copied from class: PdfObject

Gets the presentation of this object in a byte array

Overrides:

getBytes in class PdfObject

Returns:

a byte array

 int objGen)

getObjNum

int getObjNum()

getObjGen

int getObjGen()

toPdf

public void toPdf(PdfWriter writer,
 OutputStream os)
           throws IOException

Description copied from class: PdfDictionary

Writes the PDF representation of this PdfDictionary as an array of byte to the given OutputStream.

Overrides:

toPdf in class PdfStream

Parameters:

writer - for backwards compatibility
