Examples with ICCProfileWrapper org.apache.pdfbox.preflight.graphic.ICCProfileWrapper used on opensource projects

Example 1 with ICCProfileWrapper

use of org.apache.pdfbox.preflight.graphic.ICCProfileWrapper in project pdfbox by apache.

the class CatalogValidationProcess method validateICCProfile.

/**
 * This method checks the destOutputProfile which must be a valid ICCProfile.
 *
 * If an other ICCProfile exists in the mapDestOutputProfile, a ValdiationError
 * (ERROR_GRAPHIC_OUTPUT_INTENT_ICC_PROFILE_MULTIPLE) is returned because of only one profile is authorized. If the
 * ICCProfile already exist 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.
 *
 * @param destOutputProfile
 * @param mapDestOutputProfile
 * @param ctx the preflight context.
 * @throws ValidationException
