Fix color managed layer previews when adding/removing alpha:
Implement GimpDrawable::alpha_changed() in GimpLayer and emit
GimpColorManaged::profile_changed() so all cached color transforms are
nuked.
...when a color profile is active
This commit adds more (still unused) infrastructure to fix this bug:
Ee now keep around color transforms from layer pixels to "R'G'B'A
double" (which is GimpRGB's format) and back. Also add utility
function gimp_image_color_profile_pixel_to_srgb() which converts a
picked pixel to GimpRGB, using the cached color transform.
...being displayed
Need to call gimp_image_flush() on all newly opened images so whatever
image states are properly updated:
Call file_open_sanitize_image() at the end of loading (after profile
import), and re-enable the flush() call in the function.
Also, don't fiddle with undo disabling and enabling in
gimp_image_import_color_profile(). Instead, disable undo before
calling the function.
gimp_drawable_get_sub_preview(): both the preview buffer's scale
factor and the src coordinates in the drawable were calculated
wrongly. Found by Massimo.
While loading an image with color profile, gimp offers the possibility to convert it to the builtin profile. Setting the new color profile before converting, deletes the old one and results in a segmentation fault.
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).
and change GimpImage and GimpItemStack to emit the "profile-changed"
signal when the image's profile changed. Also connect GimpViewRenderer
to "profile-changed" if the viewable is a GimpColorManaged and
invalidate the preview.
gimp_image_constructed(): connect to "notify" on GimpColorConfig
and call gimp_color_managed_profile_changed() on the image.
Remove the "notify" handler on GimpColorConfig from
gimpdisplayshell-handlers.c because it already connects to the
image's "profile-changed" signal.
Additionally, implement GimpColorManaged::profile_changed() in
GimpImage and invalidate the image and all layer previews. One step
closer to color managing image and layer previews.
which currently all end in a call to gimp_color_managed_get_color_profile()
except for channels and masks. This is currently unused infrastructure but
will be used for things like layer previews, and return NULL if called
on a mask or channel, or if color management is disabled, or whatever.
Call gimp_layer_update_mode_node() also when removing a mask, and
change it to only do its magic if there actually is a mask (don't only
look at the "show_mask" boolean).
gimp_image_duplicate(): set the new image's color profile *before*
copying layers to it, or the new layers will be automatically
converted to "no color profile aka sRGB", but then tagged with the
original profile anyway.
and call it when an "icc-profile" parssite is attached or detached.
This removes code duplication and creates a place to conveniently
update more cached profiles and transforms, such as from/to sRGB for
color picking and applying.
if the same name is set via gimp_object_set_static_name() or
gimp_object_take_name() (gimp_object_set_name() and
gimp_object_set_name_safe() already had the check).
Since this is a slight behavior change it might have subtle side
effects; it definitely fixes GimpThumbBox thumbnail state to not
always re-create the thumbnail on click, which was happening since
porting to GFile (which switched from gimp_object_set_name() to
gimp_object_take_name()).
...when a color profile is active
This commit doesn't fix anything, but it prepares the code to do the
right thing:
It passes the actual raw image pixels through the entire color picking
mechanism to the widgets which display colors, particularly
GimpColorFrame.
This is needed for GimpColorFrame's "Pixel" mode (as opposed to its
RGB, HSV etc. modes) which is supposed to show the raw pixel values
from the image.
Before this commit, it was recreating the raw pixel values from the
GimpRGB value it knows, which will become impossible when we correctly
pick color managed GimpRGB values soon.
Add gimp_image_import_color_profile(), a GUI vtable entry
query_profile_policy() and a new dialog which returns the profile
policy and the profile to convert to. Get rid of the wrapper that
calls the lcms plug-in for that dialog, the plug-in is now completely
unused.
This commit doesn't add any new features, it's just the former lcms
plug-in dialog implemented in app/ (except the little fix that it is
now aware of linear vs. gamma images).
Get rid of the "configurable RGB working space profile".
Instead, turn GimpColorConfig's "rgb-profile" property into a
"Preferred RGB profile" thing that is only a hint and never used
without explicit user interaction. Present it next to the built-in
profile in the profile combo boxes and call it "Preferred" in the
prefs dialog and its tooltip.
Most importantly, don't use it as the image's profile when the image
is not tagged with a profile. Untagged images are now always in the
sRGB or linear RGB built-in color spaces.
This commit reduces the "Apply color profile" dialog on file import to
a simple "Convert to built-in RGB", but that dialog is about to be
moved to the core and improved anyway.
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.
also add "GType old_type" to GimpItem::convert() so implementations
can do things depending on the type of the original item.
In gimp_layer_convert(), if the original item is also a layer, and
color management is not off (with a FIXME because this is the wrong
check), pass convert_profile = TRUE to gimp_drawable_convert_type().
There is no color profile conversion anywhere behind this, this is
just an API change commit.
gimp_layer_new_convert_profile(): if there is a profile, always use
lcms to copy between the buffers, to avoid the additional gamma
conversion gegl_buffer_copy/get() would do in some cases. This should
fix copying between linear and gamma images.
In gimplayer-new.c, convert new layers to the image's profile if color
management is not disabled in prefs. This should convert pixels from
whatever source if they have a profile attached. If they don't have a
profile, no conversion is done. I'm not entirely sure if this
automatic conversion is always the right thing to do, please test.
- gimp-image-set-filename PDB wrapper: implement the same there in
a few lines
- xcf-load.c: use gimp_image_set_file() instead, and get rid of the
last use of filename in xcf/ in favor of GFile
