ValidationException

validateStreamObject

public void validateStreamObject(PreflightContext context,
                                 COSObject cObj)

checkFilters

protected void checkFilters(COSStream stream,
                            PreflightContext context)

This method checks if one of declared Filter is LZWdecode. If LZW is found, the result list is updated with an error code.

Parameters:

stream - the stream to check.

context - the preflight context.

checkStreamLength

protected void checkStreamLength(PreflightContext context,
                                 COSObject cObj)
                          throws ValidationException

Throws:

ValidationException

checkDictionaryEntries

protected void checkDictionaryEntries(PreflightContext context,
                                      COSStream streamObj)

Check dictionary entries. Only the Length entry is mandatory. In a PDF/A file, F, FFilter and FDecodeParms are forbidden

Parameters:

context - the preflight context.

streamObj - the stream to check.
