I don´t see any need to integrate a "color management of flag" directly into DeviceXXX PDF files.


How do you communicate to pdftoraster when /DeviceRGB means sRGB vs actually meaning /DeviceRGB?

For a PDF spool file, you can do this with /DeviceRGB without OutputIntent, vs /DeviceRGB with OutputIntent.

For PostScript you don't have OutputIntent, so how do you differentiate for PostScript?
