Thanks for your reply.
FLTK on osX SL uses Generic RGB, which is not sRGB at all.
The situation for writers of colour managed applications is quite fuzzy
[1].
As a suggestion. FLTK might add an API to expose the used colour space.
On WIN32 and Linux it might return sRGB. On osX SL it can return the used
colour space. Thus interessted applications can query what to colour
correct to.
/* provide a malloced ICC profile block and its size */
int fl_color_space( void ** returned_profile_block,
size_t * returned_size );
The profile can on Linux be asked from the X11 server [2]. So
returning the first displays profile might be the right choice.
osX has shurely functions to convert a CGColorSpaceRef to a ICC profile
data blob.
kind regards
