> 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.
