      Initial space invasion commit in GIMP · e09e563a
      Michael Natterer authored
      All babl formats now have a space equivalent to a color profile,
      determining the format's primaries and TRCs. This commit makes GIMP
      aware of this.
      - enum GimpPrecision: rename GAMMA values to NON_LINEAR and keep GAMMA
        as deprecated aliases, add PERCEPTUAL values so we now have LINEAR,
        NON_LINEAR and PERCPTUAL for each encoding, matching the babl
        encoding variants RGB, R'G'B' and R~G~B~.
      - gimp_color_transform_can_gegl_copy() now returns TRUE if both
        profiles can return a babl space, increasing the amount of fast babl
        color conversions significantly.
      - TODO: no solution yet for getting libgimp drawable proxy buffers in
        the right format with space.
      - follow the GimpPrecision change.
      - TODO: everything else unchanged and partly broken or sub-optimal,
        like setting a new image's color profile too late.
      - add enum GimpTRCType { LINEAR, NON_LINEAR, PERCEPTUAL } as
        replacement for all "linear" booleans.
      - change gimp-babl functions to take babl spaces and GimpTRCType
        parameters and support all sorts of new perceptual ~ formats.
      - a lot of places changed in the early days of goat invasion didn't
        take advantage of gimp-babl utility functions and constructed
        formats manually. They all needed revisiting and many now use much
        simpler code calling gimp-babl API.
      - change gimp_babl_format_get_color_profile() to really extract a
        newly allocated color profile from the format, and add
        gimp_babl_get_builtin_color_profile() which does the same as
        gimp_babl_format_get_color_profile() did before. Visited all callers
        to decide whether they are looking for the format's actual profile,
        or for one of the builtin profiles, simplifying code that only needs
        builtin profiles.
      - drawables have a new get_space_api(), get_linear() is now get_trc().
      - images now have a "layer space" and an API to get it,
        gimp_image_get_layer_format() returns formats in that space.
      - an image's layer space is created from the image's color profile,
        change gimpimage-color-profile to deal with that correctly
      - change many babl_format() calls to babl_format_with_space() and take
        the space from passed formats or drawables
      - add function gimp_layer_fix_format_space() which replaces the
        layer's buffer with one that has the image's layer format, but
        doesn't change pixel values
      - use gimp_layer_fix_format_space() to make sure layers loaded from
        XCF and created by plug-ins have the right space when added to the
        image, because it's impossible to always assign the right space upon
        layer creation
      - "assign color profile" and "discard color profile" now require use
        of gimp_layer_fix_format_space() too because the profile is now
        embedded in all formats via the space.  Add
        gimp_image_assign_color_profile() which does all that and call it
        instead of a simple gimp_image_set_color_profile(), also from the
        PDB set-color-profile functions, which are essentially "assign" and
        "discard" calls.
      - generally, make sure a new image's color profile is set before
        adding layers to it, gimp_image_set_color_profile() is more than
        before considered know-what-you-are-doing API.
      - take special precaution in all places that call
        gimp_drawable_convert_type(), we now must pass a new_profile from
        all callers that convert layers within the same image (such as
        image_convert_type, image_convert_precision), because the layer's
        new space can't be determined from the image's layer format during
        the call.
      - change all "linear" properties to "trc", in all config objects like
        for levels and curves, in the histogram, in the widgets. This results
        in some GUI that now has three choices instead of two.
        TODO: we might want to reduce that back to two later.
      - keep "linear" boolean properties around as compat if needed for file
        pasring, but always convert the parsed parsed boolean to
      - TODO: the image's "enable color management" switch is currently
        broken, will fix that in another commit.

      Richard Kreckel authored
      This fixes many typos in comments and one in a user-visible string (msgid
      "center abscisse" changed to "center abscissa" in affected po files. too).

      Bug 756389 - Color-managing grayscale images · 50983384
      Michael Natterer authored
      Allow to set profiles on grayscale images. Change profile validation
      to check for image type and profile type. Actually the patch simply
      makes some pieces of code less restrictive. Change user-visible
      strings in the profile dialogs accordingly. Change PDB docs

      app: keep GimpImage's profile around as GimpColorProfile · 1715e1e6
      Michael Natterer authored
      not only as parasite. This way we avoid having to create the profile
      in each call to gimp_image_get_color_profile(). Also keep the built-in
      profiles around in gimp_image_get_builtin_color_profile(). Add/remove
      refs and unrefs as needed in all users of these functions.

      libgimpcolor, *: change GimpColorProfile to be a GObject · c102dde9
      Michael Natterer authored
      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
