Hi Marti,
I'm currently create a program that converts the colorspace and layouts
of Grayscale, RGB, CMYK images.
Since some information (not color channels) is added to the trail of
the normal channels, the number of channels (both normal and extra)
are not fixed.
Although I've found that cmsSetUserFormatters is just prepared for this
purpose, it seems there're no variable that can be used within the
user program. For example:
LPBYTE MyUnroll(
register _LPcmsTRANSFORM info,
register WORD wIn[],
register LPBYTE accum)
{
MY_INFO *info = ...; // how to get my parameters?
for(size_t i = 0; i < info->channels; i++)
{
wIn[i] = info->convert2Word(accum);
accum += info->bytesPerUnit;
}
accum += info->bytesToSkip;
return accum;
}
For my purpose, I added a void * member variable to _cmstransform_struct
and it's enough for me, but someone may want to do something like it.
I'm happy if you plan to add a void * member to cmsHTRANSFORM.
Regards,
