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.
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.
… 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.
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...
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.
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.
gegl:recursive-transform applies a transformation recursively to
an image. The custom GUI allows controlling the transformation
matrix using a transform-grid controller, added in the previous
commit.
gegl:color-to-alpha-plus was merged back to gegl:color-to-alpha in
GEGL, so we can change the custom propgui constructor to refer to
gegl:color-to-alpha.
Remove the threshold-range compression toggle and logic, since the
corresponding property was removed in GEGL.
Add a specialized propgui constructor for gegl:color-to-alpha-plus.
This op is currently in the workshop, but is set to be merged with
the existing gegl:color-to-alpha, so we omit the '-plus' from file-
and function-names.
The new op adds a pair of properties to control the radii, relative
to the selected color, below which colors become fully transparent,
and above which colors remain fully opaque. Allow these properties
to be set by picking a color from the image, and calculating the
radius accordingly.
Allow propgui constructors to specify an (optional) callback function
when creating pickers, to be called when a color/coordinate is picked,
similarly to controller callbacks.
Implement picker callback support in GimpFilterTool. When the active
picker has an associated callback function, call it instead of the
class's color_picked() function.
Add lots of "#include <gegl.h>" to .c files that miss it, which is
now necessary, since this commit adds a Babl* parameter in
propgui-types.h.
which is the same as g_object_class_list_properties() but filters
out the properties for which we don't want to create a GUI.
Use it in gimp_prop_gui_new().
