Method Details

isStandardICCCharacterization

private boolean isStandardICCCharacterization(String name)

validate

public void validate(PreflightContext ctx)
              throws ValidationException

Throws:

ValidationException

validateActions

private void validateActions(PreflightContext ctx)
                      throws ValidationException

This method validates if OpenAction entry contains forbidden action type. It checks too if an Additional Action is present.

Parameters:

ctx -

Throws:

ValidationException - Propagate the ActionManager exception

validateLang

private void validateLang(PreflightContext ctx)

The Lang element is optional but it is recommended. This method check the Syntax of the Lang if this entry is present.

Parameters:

ctx -

validateNames

private void validateNames(PreflightContext ctx)

A Catalog shall not contain the EmbeddedFiles entry.

Parameters:

ctx -

validateOCProperties

private void validateOCProperties(PreflightContext ctx)

A Catalog shall not contain the OCPProperties (Optional Content Properties) entry.

Parameters:

ctx -

validateOutputIntent

private void validateOutputIntent(PreflightContext ctx)
                           throws ValidationException

This method checks the content of each OutputIntent. The S entry must contain GTS_PDFA1. The DestOutputProfile must contain a valid ICC Profile Stream. If there are more than one OutputIntent, they have to use the same ICC Profile. This method returns a list of ValidationError. It is empty if no errors have been found.

Parameters:

ctx -

Throws:

ValidationException

validateICCProfile

private void validateICCProfile(COSBase destOutputProfile,
 Map<COSObjectKey,Boolean> mapDestOutputProfile,
 PreflightContext ctx)
                         throws ValidationException

This method checks the destOutputProfile which must be a valid ICCProfile. If another ICCProfile exists in the mapDestOutputProfile, a ValidationError (ERROR_GRAPHIC_OUTPUT_INTENT_ICC_PROFILE_MULTIPLE) is returned because only one profile is authorized. If the ICCProfile already exists in the mapDestOutputProfile, the method returns null. If the destOutputProfile contains an invalid ICCProfile, a ValidationError (ERROR_GRAPHIC_OUTPUT_INTENT_ICC_PROFILE_INVALID) is returned. If the destOutputProfile is an empty stream, a ValidationError(ERROR_GRAPHIC_OUTPUT_INTENT_INVALID_ENTRY) is returned. If the destOutputFile is valid, mapDestOutputProfile is updated, the ICCProfile is added to the document ctx and null is returned.

Parameters:

destOutputProfile -

mapDestOutputProfile -

ctx - the preflight context.

Throws:

ValidationException
