When set, the opacity and transparenct threshold range is compressed
to the minimal extent that would produce different results.
When the property is toggled, update the opacity and transparency
thresholds, such that the result remains the same.
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.
Add parameters, controlling the behavior and appearance of sliders,
to GimpControllerSlider. The macro GIMP_CONTROLLER_SLIDER_DEFAULT
expands to a nonmodifiable lvalue of type GimpControllerSlider,
whose members are initialized with the most common default values.
Handle the new parameters in GimpToolLine. A slider using the new
"autohide" mode is only visible when selected, or when the cursor
is close enough to the line, between the slider's min and max
values, and no other handle is grabbed or hovered-over.
... so that when the base and balance sliders overlap, the base
slider is the one that's picked, since the balance slider is
constrained by the base, but not the other way around.
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().
Switch the gegl:spiral prop gui from using a line controller to
a slider-line controller, and use sliders to control the "balance"
and "base" properties.
Add supprt for placing sliders on a GimpToolLine -- handles that can
be dragged over the line. The sliders are accesible through a new
"sliders" property, and via the gimp_tool_line_{get,set}_sliders()
functions.
Add a slider-line controller, which works like a line controller,
but whose callback also supplies/takes an array of sliders.
Note that the data type for individual sliders is called
GimpControllerSlider (in particular, it's not line specific), so
that we may use it with other controller/tool-widget types in the
future.
