Hi Poppler folks, I encountered a weird bug with some images in a PDF. It seems like CMYK data is being interpreted as RGB data, or something similar to that - the pixel stride is off causing the image to be repeated multiple times.
PDF Page file can be downloaded from: http://derp.ltd.uk/843-21307-16.pdf Example of problem image, extracted with pdfimages: http://i.imgur.com/YSTCKkb.jpg The image shows with `pdfimages` as: page num type width height color comp bpc enc interp object ID --------------------------------------------------------------------- 1 7 image 759 185 cmyk 4 8 jpx no 68 0 I have tested 2 versions of Poppler with 2 versions of LCMS and exhibit the problem. Google Chrome also has similar problems. - Evince from Ubuntu 12.10 (Poppler 0.20.4-0ubuntu1.1 with LCMS2 2.2+git20110628-2ubuntu4) without openjpeg - pdftoppm - Poppler 0.22.0 + LCMS 1.19 (custom build) - without openjpeg Example page images: - Ghostscript: http://i.imgur.com/dfLLptb.jpg - Photoshop: http://i.imgur.com/BylwJWW.jpg - Poppler: http://i.imgur.com/8cderTo.jpg (shows buggy image) The PDF was processed using SmartCreate by QuadGraphics, combined by Adobe Acrobat 8.0... unsure of the original software used to create the individual files. On a related note I'm unable to build the current Poppler from git, otherwise I would've tested with it too. Getting link errors like: Linearization.cc:(.text+0x4dc): undefined reference to `error(ErrorCategory, long, char const*, ...)
