Finally, resolved.

Convert used older version of Ghostscript when ran from PHP. Forcing it to use GS 9.10 made all the difference.

Thanks!

Thanks! Everything recomplied, I'm using gs 9.10 and libpng 1.6.8 on both systems now. I'm pretty sure exactly same icc profile files are being used but the results are still very different. On Mac I actually get very close to the desirable result but on the server the colors still look like crap ...

Hey guys, I'm converting CMYK to sRGB using color profiles and getting some weird results... Firstly, I'm almost sure my input PDF file should use US Web Uncoated SWOP V2 (though I can't detect profile using identify -verbose) but when I use that as an input profile and put sRGB as the output ...

Thanks!

If there's any image processing genius reading this who finds the problem interesting, would be able to puzzle it down and turn the resulting transformation into a single purpose program (written in language of your choice), please drop me a line at mirek@openbrand.com

I have some progress, however, still no results. I did some more experiments and read a bit only to learn this probably isn't just a spline mesh or a simple polynomial transformation. When I play a bit with the CPs in Photoshop I get this: https://dl.dropboxusercontent.com/u/3204447/Screen%20Shot ...

Thanks Fred, I just gave it a try and the result seems to be rather too triangulish :) https://dl.dropbox.com/u/3204447/triangular-out.png Do you guys have any ideas for other tools/libs that may be able to render this? I'm processing the whole job in a chain anyway and will use IM to decompose PSDs ...

Thanks! I'm going to experiment a bit further now, in the meantime... My original CPs: 0: 0 x 0 1: 122 x 0 2: 244 x 0 3: 404 x -100.00000000000001 4: 0 x 84.33333333333333 5: 122 x 84.33333333333333 6: 244 x 84.33333333333333 7: 366 x 84.33333333333333 8: 0 x 168.66666666666666 9: 122 x 168 ...

Hey guys, I'm building a rendering tool which uses PSDs as source templates and IM as a rendering engine. I've succeeded reverse engineering PSD format and now get 16 control points for warp transformation of each layer in the PSD. However, when I try to apply it to source data I get very different ...
