I apologize for the discontinuity, I'm Working on multiple projects at the moment.

Anyway here you go..

The problem is while extracting CMYK image from a PDF file. If the file opened in Photoshop and invert it, looks fine and that is the result I am looking for.

As Aandi advised I tried unzipping the stream first, but the zlib::inflate function always fails. The reason is:unknown compression method( looks like the compression method used is not Z_DEFLATED ).

Could any body advise me how to proceed on this? Why zlib inflate fail on the image stream?

The image is DCTDecoded, colourspace:deviceCMYK and the decode array is [0,0,0,0,0,0,0,0].

Thanks
Las
