Hello Pierre-Olivier,

Thank you very much for the hint to use CGImage. That helped.

I am using Generic RGB Linear, because Generic RGB still produces wrong colours.

Well.. The documentations says:
"colorSpace:
A Quartz color space object. This must be an RGB color space. Pass
NULL to use the default RGB color space. The color space is used only
for the images produced by the output image ports of the composition.
For more information on Quartz color spaces, see Quartz 2D Programming
Guide."

Best Regards,

Jonas S.
