Description Ken Sharp 2014-06-10 05:38:50 UTC
A collection of problems to address

There is no path to allow images with > 8 bits per component to be embedded in a PDF file.

Images with > 8 bits per component can't be converted to a different colour space.

It would be good to be able to convert ICCbased spaces from a PDF file into CIE spaces for ps2write.

We need to be able to ensure that ICCBased spaces are version 2 profiles, for PDF/A-1 creation.

We don't colour convert transparency blending spaces, see Bug #695306
Comment 2 Ken Sharp 2014-11-06 02:11:51 UTC
Shadings (type 2 patterns) are rendered to images if ColorConversionStrategy is not LeaveColorUnchanged. We should sample the functions, convert the resulting data to the relevant colour space and build a new sampled function for the shading instead.
