Add two private functions which are currently unused but will
become public once it's clear where exactly we need them:
gimp_color_profile_get_rgb_matrix_colorants(): returns a GimpMatrix2
with the RGB colorants.
gimp_color_profile_new_foobar(): takes an existing profile and creates
a new one with the same RGB colorants but a linear gamma TRC. To be
renamed and made more general.
Fix gimp_color_profile_get_format() to return the right format for
"cairo-RGB24": simply check for the more special cairo formats first,
then check for the general RGB models. Found by Massimo.
to not return a reference that has to be dropped. Also allow NULL to
be returned if the managed cannot have a profile. If it can have one,
get_color_profile() still always returns a profile (either the
assigned one, or a generated built-in one).
it used to be a typedef to gpointer and actually was a cmsHPROFILE.
Change its API to be more "standard", remove the public close()
function. The object caches both the cmsHPROFILE and the data/length
ICC blob, so conversions between the two become obsolete (simply call
get_lcms_profile() or get_icc_profile()).
Adapt everything to the new API, but port it in a naive way for now,
the code doesn't take advantage of the new possibilities yet (like
refcounting).
because it confuses gtk-doc and breaks some links. Also change the
"Index of new symbols in GIMP 2.x" sections to be what seems to be the
modern standard (looked at the GLib and GTK+ docs), and update some
other stuff.
which returns a GimpColorProfile instead of just an ICC blob like
get_icc_profile(). Also, it will always return a profile, as in
fall back to the built-in profiles automatically.
Which returns an lcms format given a Babl format. It also returns a
Babl format to be used instead of the passed format, but only if lcms
doesn't support the passed format.
Profiles from disk have a lower precision than those created from
scratch via lcms API. Ensure identical profiles by returning a
"loaded" profile from gimp_lcms_create_srgb_profile() (simply do a
save/load roundtrip in memory).
which returns a string meant to label the profile in the GUI, it's
either the profile's description, its model, or "(unnamed profile)" as
a fallback. Use the function instead of duplicating that logic
inconsistently and imcompletely all over the place.
The foo_DEPENDENCIES rule replaces the default dependencies, where
EXTRA_foo_DEPENDENCIES just appends to it. This was causing libgimp
and libgimpui to build out of order.
Add functions to get a profile's description, manufacturer, model and
copyright, and use them instead of implementing the same 10 times.
Also add a GimpColorProfile typedef which avoids both having to
include lcms globally or using a gpointer instead (which looks bad and
non-descriptive in an API).
