Exporting ORA images involves first creating PNGs of
the layers. To do this, we create separate images for
each layer with Gimp.Image.new ().
However, if the original image was indexed, we lose
the palette when passing the temporary image to
the PDB call. This caused us to try saving a NULL
palette, which resulted in the crash.
This patch adds a check if the image is indexed, and
copies over the palette to the temporary image.
This patch creates a GimpExportOptions class in both
libgimpbase and in libgimp. Currently it is a mostly empty
object, but it will be added to after 3.0 to allow for
additional export options (like resizing on export while
leaving the original image intact)
libgimp/gimpexport.c was removed, and most of its content
was copied into libgimp/gimpexportoptions.c. gimp_export_image ()
was replaced with gimp_export_options_get_image () in all
export plug-ins.
GimpExportProcedure has a new function to set the default
image capabilities for each plug-in on creation. It also sets up
a new callback function, which allows the options to respond to
user setting changes (such as toggling 'Save as Animation' in the
GIF or WEBP Plug-in).
The original reason to skip these was because the new _list_ API were
introspected basically to a similar function signature, except with a
useless return value, at least in pygobject binding where the list size
was also returned.
Though it seems that in fact, only the docstring was wrong. The real
signature was apparently already the same.
See: https://gitlab.gnome.org/GNOME/pygobject/-/issues/352
Therefore since the _get_ naming is more consistent compared to other
existing function, let's re-integrate the _get_ functions for array of
items or images.
This basically reverts commit 15ec254148.
Port all plug-ins to retrieve the layers
directly from the image rather than
having them passed in. This resolves some
issues with introspection and sets the
foundation for future API work.
Resolves#10932
Since GIMP distinguishes between saving
XCF and exporting image like PNG,
we should change the PDB to show
export rather than save in the function
calls.
As usual, these got forgotten!
Also colorxhtml is actually deeply broken by commit 89c359ce47 which removed
gimp_drawable_get_pixel() (Niels thought it was not used, whereas it was simply
harder to spot with bindings!).
This will have to be fixed eventually.
Hence avoiding the stderr messages. These are going to be localized with
centrally installed catalogs "gimp*-std-plugins", "gimp*-script-fu" and
"gimp*-python".
We now handle core plug-in localizations differently and in particular,
with kind of a reverse logic:
- We don't consider "gimp*-std-plugins" to be the default catalog
anymore. It made sense in the old world where we would consider the
core plug-ins to be the most important and numerous ones. But we want
to push a world where people are even more encouraged to develop their
own plug-ins. These won't use the standard catalog anymore (because
there are nearly no reasons that the strings are the same, it's only a
confusing logic). So let's explicitly set the standard catalogs with
DEFINE_STD_SET_I18N macro (which maps to a different catalog for
script-fu plug-ins).
- Doing something similar for Python plug-ins which have again their own
catalog.
- Getting rid of the INIT_I18N macro since now all the locale domain
binding is done automatically by libgimp when using the set_i18n()
method infrastructure.
- Set the "gimp30-python" Gettext domain and bind it to the proper
locale directory as installed by GIMP.
- Localize various strings with gettext.
- Remove calls to self.set_translation_domain() in
do_query_procedures(). This is technically wrong right now but I am
going to get rid of the menu item localization for plug-ins done by
the core.
- Fix return value in error case: s/GObject.Error/GLib.Error/ and anyway
in this form, the error should be a string. Using the easier form
procedure.new_return_values() instead.
- "file-png-load" uses a GFile now (like all load procedures).
The Openraster plug-in calls file-png-load and
gimp-file-load-layer but didn't check if the result
was SUCCESS. Even though I haven't seen any
failures let's improve error checking by adding
a check for a correct result.
The current openraster specification only has a limited
number of layer modes. Let's improve things a little bit
by mapping both the current and legacy layer modes
to the same openraster composite-op where available.
For the other layer modes we could examine what the
closest composite-op is, or add a GIMP specific op
(which is what Krita seems to do). For now we set
all these to the openraster equivalent of NORMAL.
Let's use the non legacy layer modes when importing/exporting
openraster images. That way we are more likely to be able to
import the correct layer modes since openraster only has a
limited number of layer modes defined.
This fixes#5838 which was caused by an incomplete port
of this plug-in to the new introspection API.
For now we do keep the n_drawables parameter of save_ora until
issue #5312 is fixed. Not doing this would cause saving to fail.
Plug-ins that work from different bindings probably want to use their
own list-type to specify arguments, rather than working with a more
cumbersome `GimpValueArray`.
This new API should make it less verbose. For example:
```
args = Gimp.ValueArray.new(5)
args.insert(0, GObject.Value(Gimp.RunMode, Gimp.RunMode.NONINTERACTIVE))
args.insert(1, GObject.Value(Gimp.Image, image))
args.insert(2, GObject.Value(Gimp.Drawable, mask))
args.insert(3, GObject.Value(GObject.TYPE_INT, int(time.time())))
args.insert(4, GObject.Value(GObject.TYPE_DOUBLE, turbulence))
Gimp.get_pdb().run_procedure('plug-in-plasma', args)
```
becomes
```
Gimp.get_pdb().run_procedure('plug-in-plasma', [
GObject.Value(Gimp.RunMode, Gimp.RunMode.NONINTERACTIVE),
GObject.Value(Gimp.Image, image),
GObject.Value(Gimp.Drawable, mask),
GObject.Value(GObject.TYPE_INT, int(time.time())),
GObject.Value(GObject.TYPE_DOUBLE, turbulence),
])
```
Apart from porting, only code logics change is the whole
encode()/decode() code because it created a string vs bytes mess and the
zipfile API apparently didn't like to deal with bytes, even though the
docs say otherwise.
It's hard to test on my UTF-8 system, so please anyone working with
non-UTF-8 paths, we welcome reports if ORA load/save does not work
properly.
Other than this, load, save and load_thumb were all tested and working
properly so far.
