which encapsulates a cmsHTRANSFORM and does all the pixel format
conversion magic. It has API to create transforms and proofing
transforms, and to convert pixels arrays and GeglBuffers.
Before, each place which has a transform had to keep around the
transform and its input and output Babl formats, and had to implement
lots of stuff itself. Now all that lives in GimpColorTransform,
removing lots of logic from many places, and pretty much removing lcms
from the public API entirely.
This removes including <lcms2.h>, LCMS_LIBS and LCMS_CFLAGS from
almost all directories and potentially allows to replace lcms by
something else.
Trick lcms into converting cairo-RGB24 pixels directly, by using
TYPE_BGRA_8 on little endian and TYPE_ARGB_8 on big endian. They have
the same byte order, and the alpha channel (ignored by lcms anyway)
takes the place of the unused byte of cairo-RGB24.
This saves two babl conversions around cmsDoTransform().
If a config is set, apply its settings when drawing the preview's
pixels. This is preparation for fixing:
Bug 467930 - color selectors are not color managed
Bug 556608 - Monitor color profile is not applied to filter preview
add 'pixel-perfect' 24x24px twins
gimp-info
gimp-user-manual
gimp-video
all current 24px icons from scalable icons-themes have now
'pixel-perfect' 24px vector twins.
Next step would be 'port' all remaining 22x22px icons to 24x24
(so 22x22 can be deprecated in future builds). As gimp refuses to use
24px for these icons, the 22px icons have to stay until gimp is ready for 24px.
which isn't really for "picking", but it just fits too nicely into
GimpPickable to not put it there.
Also add utility function gimp_pickable_srgb_to_image_color() which
takes a "real" (sRGB) GimpRGB value, transforms it to the pickable's
colorspace and puts it into an "image color" GimpRGB.
...when a color profile is active
Add GimpPickable::pixel_to_srgb() which puts a picked raw image
pixel into a GimpRGB. Default to gimp_rgba_set_pixel() but implement
pixel_to_srgb() in GimpLayer, GimpProjection and GimpImage and
run the pixel through gimp_image_color_profile_pixel_to_srgb().
Replace the 3-state "off", "display" and "softproof" radio items by
two toggles "enable" and "softproof". Also add separate controls for
display and softproof options.
Not only the logic was broken, a local variable was also shadowing the
"dest_profile" variable and preventing the broken logic to be applied
at all. Double fail.
They are unreliable because every type checking cast discards them,
they are useless anyway, visual clutter, added inconsistently, and
generally suck. Wanted to do this a long time ago, it was a bad idea
in the first place.
