This new function allows to set a title with mnemonic.
But also it properly sets the frame label as the mnemonic widget for the
radio buttons, otherwise the mnemonic is mostly bogus and doesn't
actually give focus to the editable widgets (i.e. the radio group).
This includes a new function gimp_prop_choice_radio_frame_new() which
creates GimpIntRadioFrame from GimpChoice properties.
GimpChoice GimpProcedure arguments are still creating a combo box by
default, but it is now possible to override this default behavior to get
a radio frame by calling first:
```C
gimp_procedure_dialog_get_widget (dialog, "arg-name", GIMP_TYPE_INT_RADIO_FRAME);
```
There's no seemingly good reason for it not to be introspected, so let's
add it to the files. This also fixes an issue where the documentation
for it is not properly generated.
Some minor code style issues remained
that I missed in 8adcc0cd.
After further reflection, I also converted
the code to be a private/internal function.
gimp_prop_check_button_new () should
cover the majority of GtkCheckButtons,
and the function is currently only used
to fix the size of those widgets. We could
revisit it as a public function in the
future if more use cases are found.
Resolves#10026
Selecting a checkbutton makes the label bold. This increases the
width of its label, and if it's the longest item in a box, this
causes minor "twitching" and resizing of the dialogue.
This patch calculates the size of the label when bold and then
requests the label width be set accordingly to resolve the issue.
Per Pippin, the only color model that can
have double precision is RGB/A.
Therefore, we need to switch all others to
use float instead. This patch converts the
HSV and HSVA double babl formats.
- gimp_rgb_list_names() ported as gimp_color_list_names() using NUL-terminated
GimpColorArray.
- GimpColorHexEntry uses the new function (and is therefore now GimpRGB free!).
- gimp_rgb_parse_name() deleted as it's unused since my previous commit.
With all this, gimprgb-parse.c is now deleted from the repository! \o/
New functions with the same name as these functions are created, except without
the length argument (i.e. it's equivalent to calling these with -1).
The reason for this is that using strings with a length variant which may be
negative to switch to NUL-terminated strings are not bindable. At least in our
case, when testing in Python, the input string ended up as corrupted garbage and
GObject Introspection docs warns about such interfaces:
> In particular, avoid functions taking a const char * with a signed length that
> can be set to a negative value to let the function compute the string length
> in bytes. These functions are hard to bind, and require manual overrides.
(see: https://gi.readthedocs.io/en/latest/writingbindableapis.html#strings)
So instead, I create a simple version which runs on NUL-terminated strings only
and which is bound, whereas unbinding the generic length-version (making it
C-only, or maybe usable in some other bindings which ignore the (skip)
annotation; apparently some do this).
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.
For certain min/max values of the LabelSpin widget, in combination with
zero digits, it proves impossible to change the initial value.
The reason for this is that the step size may become less than 1.0.
In which case, stepping doesn't work because the number of digits is
set to zero.
Let's check for this situation and when digits is zero set the step
to 1.0 and make sure that page is at least the same value.
While testing this I also noticed another issue: when initializing
the upper value was set to 0.0 and the lower to 1.0 which leads to
a critical because lower > upper.
We fix this by switching the initial upper and lower values.
Build for macOS on CI breaks with:
> ../gimp3-2.99.19/libgimpwidgets/gimppickbutton-quartz.c:210:45: error: use of undeclared identifier 'monitor_profile'
> space = gimp_color_profile_get_space (monitor_profile,
Resolves#11246
On Windows, a CRITICAL was being repeatedly thrown if you
didn't have a monitor profile set. This is because we were trying to
pass a NULL value to g_utf16_to_utf8 () whenever we needed to
convert a GeglColor.
This patch fixes it by checking if the monitor profile filename is NULL
before trying to convert it.
We dereference "file" twice in gimp_prop_file_chooser_button_callback(),
once in the GIMP_IS_PARAM_SPEC_CONFIG_PATH () condition and then
at the end of the function. This is likely due to a similar structure in 2.10,
which did not have a second condition.
As a result, any Gegl filter which had a file property would crash if set from
a GUI. The first g_object_unref() is removed so we only dereference "file"
once.
Resolves#11146
As Idriss Fekir and I noted, 5ce128a9 added support for
receiving GeglColor data to GimpColorAreas, but
retrieving it still resulted in RGBA application/x-color
values being stored when dragged.
This patch updates gimp_color_area_drag_data_get () to
give the format and profile information along with the
pixel values.
Mainly fixing GimpRGB comments and
parameters that are unused (or in unused
functions).
GimpCircle and GimpGradientChooser
have color conversions ported to use
GeglColor exclusively.
While the buffer used by Cairo may have a rowstride bigger than 3 * width, our
internally stored buffer has the exact size required for drawing the scale.
When changing the selected color, we have no reason to redraw the Z preview.
This preview should only be redrawn if the allocation size changed, or if we
change the previewed model or the Z component.
As for the XY preview, it should only be redrawn if the Z value is changed (and
of course, similarly, if the allocation changed or if model or Z component
changed).
No custom conversion code anymore. This also fixes some bugs in HSV when
I was wrongfully multiplying the hue by 360 when mixing babl and custom
code paths.
Until now we only had the case of the CMYK color selector using the
soft-proofing profile. Yet this is also interesting for other color
selectors, in particular to show out-of-gamut colors. Indeed if we
enable soft-proofing on the active image, it is interesting to show the
intersection of the current RGB/Grayscale space gamut with the
soft-proofing gamut.
Right now, this is only used in GimpColorSelect when showing colors in
LCh color space.
This commit adds gimp_color_selector_set_format() which is meant to give
awareness of the target color format for which we are selecting colors.
Right now, I am only using this information on the Scales selection
method, which means that now colors you read and select are in the
target space. Even better, the out-of-gamut shown happens in the with
LCH scales is for the target space too. As tested, it already makes
quite a difference for an image in sRGB vs. say adobeRGB.
Note that right now, I only use the format information as a space, but
in fact, I made the API to be about a format because the actual format
can be used wisely too. First we may want to do different thing
depending on the color model itself (which the space may give away or
not, especially when using default spaces or when we'll have images
using models with no space in the future, such as CIE Lab). But also
whether the image is following the space TRC or is linear (or
perceptual) would change how we represent the data. If we were to show
non-linear values in the Colors dockable but when painting, the color
picker shows linear values for instance, it might be puzzling to people.
What this commit does is keep the same code logic while moving to
GeglColor. Yet it's not **really** space-invaded yet. What we need to do
now:
1. Take into account the image space, and this is what we must navigate
through, in particular for various representations of RGB or HSV.
I.e. that if the active image is in anyRGB, the RGB values shown must
be within anyRGB. Right now, everything is still shown/used as sRGB
(even though it's properly retrieved and transformed to the target
space thanks to GeglColor).
2. Show space info to make things clear and explicit, by adding some
label somewhere.
3. Allow to switch between image and softproof spaces, regarding
out-of-gamut display. I.e. that while RGB/HSV must be shown within
the image space (assuming it's anyRGB), we may want to show
out-of-gamut area (pink areas) within the softproof space. This may
mean adding a checkbox. Or maybe simply taking into account whether
we are in softproof mode or not?
4. We can likely move off gimp_widget_get_color_transform() into using
gimp_widget_get_render_space() for display drawing. We don't need any
soft-proofing or black point compensation for any of these widgets so
pure babl is fine. Indeed we want to show any in-gamut color
correctly (and not transformed according to specific intents or
through soft-proofing). We will take care of the proofing case with
out-of-gamut area showing only.
5. In the various drawing functions, we should move to
CAIRO_FORMAT_RGBA128F. The color selection area might be wide enough
that it makes sense to be more accurate, especially as we are
essentially showing color gradients in 1 or 2 directions in these
various widgets.
- New libgimpcolor functions: gimp_color_parse_hex() and gimp_color_parse_name().
- GimpColorHexEntry is now space-invaded. Though recognized color names
and hexadecimal syntax are sRGB only (because CSS and SVG
specifications explicitly say that this syntax is for sRGB values), it
is possible to enter non-sRGB values with
gimp_color_hex_entry_set_color().
- GimpColorSelection is now space-invaded.
The invasion extended to some core widgets too, in particular GimpColorPanel (a
subclass of GimpColorButton). There was quite a lot of code depending on these
widgets.
This includes improvements on the out-of-gamut colored corner being shown for
unbounded component types out of the [0; 1] range (with some small margin of
error to avoid e.g. a -0.0000001 value to show as out-of-gamut).
There are still improvements to be made on the color rendering. In particular,
it still draws as CAIRO_FORMAT_RGB24 cairo surface. We should probably move to
draw as CAIRO_FORMAT_RGBA128F eventually (more precision and even allowing to
draw unbounded colors with a possible option, instead of always clipping).
Also adding the libgimpwidgets API gimp_widget_get_render_space().
- New function gimp_cairo_set_source_color() which is meant to replace
gimp_cairo_set_source_rgb(a?)() eventually. This new function sets the Cairo
source color, using the target monitor's profile of the widget where the Cairo
surface is meant to be drawn on. It also uses the color management settings
(such as whether a custom profile was set, instead of using system profile, or
also simply whether color management was disabled at all). It doesn't
soft-proof the color yet.
- Padding and out-of-gamut colors drawing now use the new
gimp_cairo_set_source_color(). These don't need any soft-proofing anyway.
- Out-of-gamut color property in GimpColorConfig is now a GeglColor property.
We pass 2 GeglColor through the wire now. Since it is passed very early
(when sharing the configuration), I had some issues with initialization
order of GEGL, and in particular when calling gegl_init() before
gegl_config() inside _gimp_config(), I had a bunch of such criticals:
> Plugin script-fu: GLib-GObject: CRITICAL: Two different plugins tried to register 'GeglOpPlugIn-transform-core'
Anyway in the end, I store the passed colors as raw bytes and strings in
the GPConfig object, and re-construct the GeglColor last minute in
_gimp_config().
- 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.
