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.
The two threshold color pick buttons needed to have
a GeglColor parameter for their GimpPickerCallback
rather than a const GimpRGB.
This also fixes a crash caused by trying to free the GeglColor
rather than unreferencing it.
In particular, the Curves, Levels and Operation tools method implemented
are updated. Also GeglColor arguments in GEGL operations are not
transformed into GimpRGB arguments anymore in GIMP. GeglColor GParamSpec
stay GeglColor now.
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().
… gimp_prop_widget_set_factor() to libgimpwidgets.
Now that GimpSpinScale is in libgimpwidgets, it's time to move the
associated prop too, to make it a prop widget with such a widget easily
creatable by plug-ins.
While doing so, I update both these functions logic, binding properties
together with the g_object_bind_property*() APIs (as we do already in
some other recent prop functions) rather than connecting to signals
ourselves. It makes for much simpler code.
There is really nothing specific to the core application, it is quite a
generic widget, so it would be nice for plug-ins to be able to use this
widget.
Reported by Massimo, though this one is wrong, as far as I can see.
`ninja scan-build` apparently reports `result` as being returned after
being freed here. But actually since we are setting the `error` with
g_set_error() in the same time we free `result`, we would also enter the
`if (*error)` block a few lines later, which would return NULL and not
`result` anyway. I guess the static analyzer could not see that far.
Still, set the pointer to NULL with g_clear_pointer(), which should be
enough to make the static analyzer happy.
Since it appeared with GLib 2.68.0, we could not change this until we
bumped the dependency which has only become possible a few days ago
(since Debian testing is our baseline for dependency bumps). Cf.
previous commit.
As this is a drop-in replacement (just a guint parameter changed to
gsize to avoid integer overflow), search-and-replace with:
> sed -i 's/g_memdup\>/g_memdup2/g' `grep -rIl 'g_memdup\>' *`
… followed by a few manual alignment tweaks when necessary.
This gets rid of the many deprecation warnings which we had lately when
building with a recent GLib version.
... by grouping the geometry options, which can be controlled
through the on-canvas UI, in an expandable frame, which is
collapsed by default. The shape option is not part of the group,
and is moved to the top.
In _gimp_prop_gui_new_generic(), when a pair of consecutive
properties have "range-start" and "range-end" roles, respectively,
and "luminance" units, use a range prop-widget for both properties,
as per the previous commits.
The range is sorted by default, unless the first property has a
"range-sorted" key of "false".
gegl:focus-blur blurs the image around a focal point. It can be
used to create fake depth-of-field effects.
Add a prop-gui constructor which uses a FOCUS controller to control
the focus geometry.
and remove a gazillion gtk_widget_show() all over the place, some
places need a gtk_widget_hide() now, and I'm pretty sure I broke at
least one thing in all those files...
paste as brush, paste as pattern, select to new brush, select to new pattern
fill selection outline, fill path, stroke selection, distort, rounded rectangle
indexed color conversion, merge visible layers, new guide, new guide (by percent)
image properties, newsprint, fractal explorer, sample colorize, new layer
metadata editor (just a button), spyroplus (only common buttons)
Don't assume that "toggled" signal means that toggle status actually
changed.
Though issue #3133 got fixed with my previous commit, let's make sure we
never create several GBinding for the same GimpChain by always checking
existence of a previous one after a "toggled" signal.
Also only create a GBinding object if one doesn't already exist.
"binding" data can be set to NULL. Do not assume it is a proper object.
Also I was tempted to use g_object_set_data() to simply free the
GBinding object on setting a new data, but such object will also be
freed when the widget is destroyed by default. So that would also end up
in double destruction. Instead just keep current logics.
This CRITICAL was reported in #3133 but this is not the main bug.
Add on-canvas GUI (simple lines) for circular, linear and zoom motion
blur. The restrictions in the interaction show pretty well that there
is room for improvement here, the line is just a bit too generic, but
it's better than nothing.
...have the same scaling
gimp_prop_widget_new_from_pspec(): when restricting the scale to the
actual op area for pixel-coordinate and pixel-distance properties,
only use the max value in the axis direction for pixel-coordinate; for
pixel-distance make sure we use the same value on both axes, simply
use MAX (area.width, area.height).
When constructing a prop-GUI widget for an angle property with a
dial, use the the property's "direction" UI-meta, if exists, to set
the direction of the dial. Together with GEGL commit
7b0578073a0f20334b5a8a8fe57b649d9f302454, this fixes wrong dial
direction in certain ops that use clockwise angles.
... and rename "clockwise" to "clockwise-delta"
Add a boolean "clockwise-angles" property to GimpDial, which, when
set, causes the dial legs' angles to be measured clockwise, rather
than counter-clockwise. The property is FALSE by default.
Rename the "clockwise" property, which controls the direction of
the measured delta between the two angles, to "clockwise-delta", to
avoid confusion, and adapt the rest of the code.
gegl:recursive-transform-plus is an extension of
gegl:recursive-transform, allowing multiple transformations to be
applied simultaneously; it will eventually be merged back into
gegl:recursive-transform. See GEGL commit
9829bc22e85526d789c4e80c05949d4c6202a207.
The GUI uses the new TRANSFORM_GRIDS controller, allowing adding,
duplicating, and removing transformations, and controlling them
through on-canvas transform grids.
... which is similar to the TRANSFORM_GRID controller, supporting
multiple transformation matrices.
Implement the TRANSFORM_GRIDS controller in GimpFilterTool, using
the new GimpToolWidgetGroup to display multiple transform grids.
After the switch of random-seed properties from INT to UINT, their
upper bound results in a negative value when converted to a
gint32, causing a CRITICAL in the call to g_random_int_range().
Use g_random_double_range() instead, which has enough precision to
accurately represent all values in the range, and round the result.
