Comment (by cehoyos):

 Am I correct that "XYZ" is independent from 12-bit?
 If yes, is it possible to create a similar sample with 8bpp? The reason I
 ask is that I see three different problems with the sample you provided,
 the first being that the libopenjpeg decoder wrapper currently only
 supports 8 and 16 bpp and refuses to decode 12bpp. The second problem will
 be that the jp2 image does not say anything about its colour-space
 (OPJ_COLOR_SPACE == 0) so I suspect it will be detected as RGB, only the
 third problem will be the transformation from XYZ to RGB.

 (And could you create a 12bpp RGB sample?)
