[poppler] lcms usage in poppler

[Thomas Freitag]

Hi Folks!

Can anybody tell me how I can really test the lcms integration in 
poppler? I thought it should work, but now I'm no more sure. Reason for 
the change of my mind is that I tried to implement the usage of 
OutputIntents. Motivation is the GWG, patch series 7 (07_OutputIntent), 
but the result of my first tests is not really satisfying, s. 
attachments. Of course it's a little bit better than without my 
implementation, see i.e. the shading cross. But it's not like it should 
be. So I'm wondering now if the reason for it

1. is my wrong implementation (but in the debugger I saw that the lcms 
transformation is called) or
2. is the integration of lcms in poppler, at least in the CMYK area (I 
need to test it there, because the profiles in the PDF are CMYK profiles) or
3. is lcms with this kind of profiles (the profiles are REALLY small for 
CMYK profiles, normally I see CMYK profiles with a size of at least 512 
kByte).

Cheers,
Thomas
