Does anybody know how to use Littlecms functions in ImageMagick?
How to convert colorspace of Image object (c code api) with defined
profile (ICC) ?
This is done via a ProfileImage() function. The profile is supplied
as an in-memory BLOB. If the image does not already have a ICC
profile attached to it, the call to ProfileImage() simply attaches to
supplied profile to the image and no transformations are done to the
pixels. If the image already has an ICC profile, then ProfileImage()
invokes the CMS transform based on the two profiles to convert the
image pixels to the target space.
The functioning is really simple and is definitely not a "system" but
it works well in the hands of a CMS expert.
I still have problem with colorspace conversion and don't know how to
load ICC prifile from file. Which function does that thing? What is
exactly datum argument in ProfileImage() funciton?
Can you give me some example how to use this function and make
ColorSpace conversion...?
Thanks.
