Jermias,

unfortunately I have currently very little time, so no work done here.

cool to see that you are working on it. I'll try some tests, but it may be a while...

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). colors should now be properly mapped to the target device even if it's a

Max,


working on implementing some level of PDF/X-3:2003 support for FOP.
PDF/X-3:2003 because it can be used together with PDF/A-1. There's a
mean little detail in the PDF/X spec that says the output intent must

Since all Output Device Profiles I found so far are CMYK profiles I
obviously need to look into this a little. What I'm planning is to

sRGB to the target CMYK profile.

What I'd like to know is whether you've already done some work in the
CMYK area. Not that we duplicate our efforts.

I know you're interested in better color handling in FOP. I'm currently use an "Output Device Profile" which sRGB isn't (It's a Display Profile). properly map XSL-FO's sRGB values into proper sRGB color values in the PDF (by mapping DefaultRGB into sRGB). That way I can avoid converting colors early and still indirectly set up the color transformation from
