Problematic PDF

Converting PDF to PNG produces incorrect colors compared to those of Acrobat which are correct. Adding option UseCIEColor, however, produces correct colors like those in Acrobat (but this option should not be necessary to use, AFAIK).

I am using revision 12309 (current head) with command line that causes incorrect colors:

gs -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dUseCropBox -r200 -sOutputFile=debug.png debug.pdf

Now, add option UseCIEColor and colors will be correct:

gs -dUseCIEColor -dSAFER -dBATCH -dNOPAUSE -sDEVICE=png16m -dUseCropBox -r200 -sOutputFile=debug.png debug.pdf

Without UseCIEColor, the black boxes (on which every price is placed on) will be purple-ish.

The problematic PDF has been attached.

I tried this file with the head and it renders correctly for me.

Michael, you're right, this has been fixed in HEAD
