Subject Re: Having a problem using PDFParser
Date Fri, 09 Aug 2013 18:11:55 GMT
Hi Andreas,

in using PDFDebugger (great tool BTW) i found the following.

now please correct me if i'm looking at the wrong data,

i have found the filter used for the working PDF file is to be DCTDecode

and for the PDF files not working correctly, i have found a filter of jpxdecode and jbig2decode

i am using a fresh download of 1.8.2 


Thanks

Alain

I guess it depends on the used image encoding (CCITT, DCT, JBIG2, JPX etc.),
some are well supported others are not. Do you get some console log output 
(complains about unsupported filters)?
