I just went ahead and finished this as explained earlier. It was so easy to do. So, we now have initial support for PDF/X-3:2003 and improved PDF/A-1b support. Documentation will follow shortly.
I learned a lot about color handling while implementing this stuff. I think that having all standard colors properly defined as sRGB in PDF is a step further to ensure that FOP doesn't break the color intention from XSL-FO when it generates PDF (uncalibrated, device-specific RGB vs. sRGB). Together with the new possibility to specify an output profile, the colors should now be properly mapped to the target device even if it's a CMYK device (Confirmation from a professional pending, of course). :-) On 14.06.2006 10:29:21 Jeremias Maerki wrote: > Max, > > I know you're interested in better color handling in FOP.

Not that we duplicate our efforts. Jeremias Maerki
