When rendering a pdf to a png using the "png16m" or "pngalpha" devices, the colors in the output image are screwed up. In particular i've noticed that colors are a lot lighter, or at least greens are rendered a lot lighter than in the original file. I've seen this reported in many forums (without any workaround) but curiously enough this is not in the bugtracker... Example command: gs -dNOPAUSE -dBATCH -dUseCropBox -sDEVICE=png16m -r100 -sOutputFile=outputfile.png inputfile.pdf
Sorry yes it was in the bugtracker (692072) and it is fixed in the latest version. I did search, but the search engine only searches for open bugs by default, that's why I didn't find it :$ *** This bug has been marked as a duplicate of bug 692072 ***
