[Lcms-user] 32-bit integer ICC profile conversion

[Elle S. <l.e...@gm...>]

Hello all,

I'm attempting to add to Gimp the ability to do ICC profile
conversions on 32-bit integer images. I saw in the lcms2.4
documentation a reference to some macros for defining a new formatter.
But I haven't a clue how to use those macros.

I looked in lcms2.h at the #define statements and hazarded a guess
that putting the following line:

#define TYPE_RGB_32
(COLORSPACE_SH(PT_RGB)|CHANNELS_SH(3)|BYTES_SH(4))

in the Gimp color conversion code might do the trick. But it didn't
work. Any pointers on how to add support for 32-bit integer profile
conversions would be very welcome.
