This is meant to obsolete GeglParamColor with at least an additional argument
has_alpha which we need in GIMP. It allows to advertize when a parameter wants
an opaque color, which in particular means we know when displaying a GUI to pick
colors with alpha or not.
Resolves#10992.
GimpTextLayer's color attribute was
updated from GimpRGB to GeglColor,
but gimp-text-layer-set-color still passed
in GimpRGB. This patch updates the PDB
call to match the property type.
One of the big improvement in this commit is that text layers are now much
better at space accuracy. They were already space-aware, yet rendered as sRGB u8
only before being converted to the image's space. It means that text layers had
the following limitations:
* Any color out of sRGB gamut were trimmed.
* Precision was always 8-bit (even if the image was high-bit depth).
Now GimpTextLayout keeps track of its source space (for RGB and CMYK only, this
won't be as easy when we will support more backend, since Cairo has only RGB
support for image data) and the image TRC (in case it bypasses the color space's
TRB) and it draws within this gamut and space.
It means first that we are not limited to sRGB colors; we will draw text main
color in the full image gamut, with still 2 remaining limitations:
* Unbounded colors are impossible because Pango format (to color text) uses
hexadecimal (so even with half/float images, you can't draw out-of-gamut text
unfortunately).
* Main color precision is still 8-bit, yet a tiny bit better than before as we
at least follow TRC (so we avoid some of the precision loss when converting,
even though the bit-depth is still the biggest loss).
The outline color on the other hand is drawn through Cairo API entirely, in
float. This means that the outline color will now be without any precision loss.
Note that this depends on CAIRO_FORMAT_RGBA128F which is only available since
Cairo 1.17.2 which is not in Debian bookworm (our current baseline for GIMP
3.0). It means that the old precision will still happen with older Cairo
version, as determined by #if code at compilation.
- app: gimp_context_get_(foreground|background)() are now returning a GeglColor.
- libgimp: PDB functions named similarly in libgimp are returning a newly
allocated GeglColor too.
- A few other PDB functions (the ones using these functions) were updated and
their signature changed to use GeglColor too, when relevant. Plug-ins which
use any of the changed libgimp functions were fixed.
- GimpContext: signals "(foreground|background)-changed" are now passing a
GeglColor.
- libgimpconfig: new macro GIMP_CONFIG_PROP_COLOR using gegl_param_spec_color().
- GimpContext: properties "foreground" and "background" are now GeglParamColor
properties.
- app: All code interacting with GimpContext objects were updated to receive a
GeglColor (that they may still convert, or no, to GimpRGB for now).
- app: gimp_prop_gegl_color_button_new() was added as an alternative to
gimp_prop_color_button_new() when the property is a GeglParamColor. Eventually
the former should replace completely the latter.
- libgimpwidgets: gimp_prop_color_area_new() now works on GeglParamColor
properties only.
- libgimp: gimp_procedure_dialog_get_widget() will generate a GimpColorArea for
GeglTypeParamColor arguments.
This function is not perfect and in particular doesn't seem usable with binding
because of GimpUnit being some weird mix between an enum and some kind of class.
So this will have to be fixed too. See #8900.
… function gimp_font_get_pango_font_description().
Also updating file-pdf-save which is the only plug-in using these right now.
Note that I am not fully happy with the new function
gimp_font_get_pango_font_description() because I experienced some weird behavior
in file-pdf-save which is that some fonts were wrong if this is called after
pango_cairo_font_map_set_resolution().
But let's say this is a first step looking for improvements.
In GimpText, The font used to be stored as a string containing its name,
Now, it is stored as a GimpFont object, which makes more sense and makes
operations on fonts easier (such as serialization).
Now text layers are proper types, which means that the binding API will also be
nicer (e.g. `txt_layer.set_text('hello world')` in Python).
This commit also adds the param specs allowing to create plug-in procedures with
text layer parameters.
Finally it fixes the few calls in file-pdf-save (apparently the only plug-in
using specific text layer API right now) with explicit type conversion.
After re-reading #534, I realized I missed the discussion about unsupported
markup by the tool. Then I tested and confirmed what Ian Munsie initially said
in a comment: unsupported markups are properly rendered in the text layer, yet
are simply dropped when editing with the text tool.
This is actually the ideal behavior as it means that with the API, you can even
go further than what is currently possible with the GUI. So it gives nice powers
to people who can script GIMP. We still need some warning in the function
documentation to tell developers about this weakness in the tool GUI.
This complements the existing text_layer_get_markup function and allows
scripts to create and modify complex text layers.
It adds the <markup> root tag if it was not supplied and will run the
markup through pango_parse_markup() to check for errors.
Reviewer's (Jehan) note: this is a mostly untouched patch contributed in #534,
except that code moved around. I also fixed the header set in the .pdb, a link
to pango markup docs and added the meson changes.
Fix the dependency by making the stamp an actual (yet empty/no-op)
header file which is included by all generated source file. This way, we
ensure that meson rebuild .o files when the .pdb sources are changed.
This is the second solution proposed by eli-schwartz here:
https://github.com/mesonbuild/meson/issues/10196#issuecomment-1080053413
Turn all ID param specs into object param specs (e.g. GimpParamImageID
becomes GimpParamImage) and convert between IDs and objects in
gimpgpparams.c directly above the the wire protocol, so all of app/,
libgimp/ and plug-ins/ can deal directly with objects down to the
lowest level and not care about IDs.
Use the actual object param specs for procedure arguments and return
values again instead of a plain g_param_spec_object() and bring back
the none_ok parameter.
This implies changing the PDB type checking functions to work on pure
integers instead of IDs (one can't check whether object creation is
possible if performing that check requires the object to already
exist).
For example gimp_foo_is_valid() becomes gimp_foo_id_is_valid() and is
not involved in automatic object creation magic at the protocol
level. Added wrappers which still say gimp_foo_is_valid() and take the
respective objects.
Adapted all code, and it all becomes nicer and less convoluted, even
the generated PDB wrappers in app/ and libgimp/.
on behalf of plug-in authors who have no style or can't type.
Instead, simply reject non-canonical procedure names and remove all
code that keeps aroud the original non-canonical shit just to pass it
back to the plug-in.
Don't unconditionally overwrite all the proc's description, author
etc. Instead, try to preserve them and append the "Deprecated" notes
to the help texts and generated comments.
Only affects one procedure because we killed the meta info of all
other deprecated procs so far, but now we don't have to do that any
longer.
called GimpPDBItemModify that currently has one member
GIMP_PDB_ITEM_CONTENT, in order to be prepared for adding
the "lock position" feature from bug 674160.
Set the text box mode to "fixed", and convert the passed in pixels to
the text layer's unit when setting the text box' width and height.
