Error when decoding CCITT compressed data that contains EOLs, fill bits etc.
----------------------------------------------------------------------------
Key: PDFBOX-1086
URL: https://issues.apache.org/jira/browse/PDFBOX-1086
Project: PDFBox
Issue Type: Bug
Components: Parsing
Reporter: Jeremias Maerki
Assignee: Jeremias Maerki
The TIFFFaxDecoder class (originally coming from JAI via XML Graphics Commons)
does not handle cases like EOLs between lines and in front. But the PDF
CCITTFaxDecode filter needs to allow many different variants of the encoding.
Apparently, TIFF has a relatively restricted way of encoding CCITT data, so
TIFFFaxDecoder was not written to be as flexible as we need it. Ideally, PDFBox
should handle anything that gets thrown at it.
It apprears that it would be rather difficult to retrofit TIFFFaxDecoder with
the necessary flexibility. So, new decoders for T.4 and T.6 should probably be
written.
