When opening this PDF in Photoshop(CS3) all colors are automatically inverted.
How can I change this behaviour? The file has correct colors when opening it with Adobe Acrobat.
The file is generated by ImageMagick 6.5.6-8 2009-10-20 Q16 Open MP.
Opening a 'regular' PDF file in Photoshop does not give me any problems.
Please correct me if I'm wrong, but I believe that ImageMagick is not properly embedding the color profile when generating the PDF. This is why Photoshop strips it, and turns it to negative.
Perhaps the reason why Adobe Acrobat shows it correctly is because it automatically fixes bad color profiles?
