file_save(): make sure we always set an error on failure
file_save_dialog_save_image(): additionally, check that "error" exists
before dereferencing it.
... the XCF file
Add a "saving" signal to GimpImage, which is emitted when the image
is about to be saved or exported (but before it's actually saved/
exported). Connect to this signal in tool-manager, and commit the
current tool in response (unless its GimpToolControl::preserve is
TRUE).
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.
libgimp:
- 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.
plug-ins:
- follow the GimpPrecision change.
- TODO: everything else unchanged and partly broken or sub-optimal,
like setting a new image's color profile too late.
app:
- 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
GimpTRCType.
- TODO: the image's "enable color management" switch is currently
broken, will fix that in another commit.
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
...after exporting the image
Call gimp_image_name_changed() in both gimp_image_clean_all() and
gimp_image_export_clean_all() so we clear the cached displayed URI in
all cases, even if this means we're emitting "name-changed"
redundantly some times.
Optionally convert all imported (not XCFs) images to 32 bit linear
floating point, and optionally add a little noise in order to
distribute the colors minimally. The new options are on a new "Image
Import & Export" prefs page that needs a new icon. Original dithering
patch by pippin.
This got lost when dropping the file-uri plug-in and switching to
interal download using GIO. The file-uri plug-in would just download
whatever remote thing and open it locally, using local magic matching.
We now do the same internally and try the magic matching again on the
downloaded file.
do not access progress object after destruction.
silence warnings like:

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.
file-procedure.[ch] is gone and its functions moved to
GimpPlugInManager where they belong (the manager keeps around the
lists of load, save and export procedures).
Utility functions from file-utils.[ch] that have nothing to do with
image files moved to core/gimp-utils.[ch].
...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.
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).
Remove the check for opening a regular file from
file_open_dialog_response() and call the functions in file-open
unconditionally. This is the actual fix because the check was simply
bailing out with no message or anything when trying to open a
non-regular file, whereas the checks in file-open return proper error
messsages.
In file_open_image(), do the checks for being a regular and readable
file first, so we don't run into reading from other files when trying
to figure the file format.
We need to mount every non-native GFile's volume, regardless of
whether the file procedure uses GIO directly or needs file-remote to
download/upload the file. Move the entire mount logic to a new
file-remote function and change gimp-gui.c and gui-vtable.c to only
return a GMountOperation. Try to mount every non-native file in
file-open.c and file-save.c and bail out if mounting fails. Simplify
the uploading and downloading code accordingly.
- change start() and set_text() to use "format" and "..." instead of
"message", allowing to format progress messages in place
- s/cancelable/cancellable/
- move "cancellable" to be the second argument of start()
