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 is a first commit to really getting rid of GimpRGB within core and
PDB/plug-in code. This will make color conversion reliability a lot better as
GeglColor will handle conversions for us. The goal is that we should keep origin
color space (for instance when picking colors in a GimpPickable, or when storing
in the FG/BG colors or in paletters) until the last second and convert at use
only.
It's still very much work-in-progress.
If you run the GEGL Operation tool without choosing
a filter, it leaves a "gegl:nop" layer effect behind.
This is not useful, so we check and set such filters as
destructive to get rid of when applying an effect.
The list of objects where the config object is a dedicated custom class (instead
of a runtime-registered class) is well known. These are the operations
registered inside gimp_operations_init().
The list inside gimp_gegl_procedure_execute_async() which the previous commit
was updating was not right: it was still missing "gimp:hue-saturation" and
"gimp:threshold" should not have been on the list (this was generating a
CRITICAL when trying to get the "config" property on this object).
Instead let's add some init/exit() functions in gimp-operation-config API to
distinguish the operations with custom config (registered during init) with all
the others. Then we add gimp_operation_config_is_custom() which can be used
everywhere where we want to verify if an operation is using a custom-made config
object or a generated class just mirroring the operation properties.
This way, we should not get out-of-sync anymore.
Adds gimp:color-balance to the list of
GIMP-specific GEGL operations we
retrieve the GimpConfig settings from.
Also prevents trying to set a GEGL
property when editing if it couldn't be
converted properly (e.g. GimpConfig)
*It's possible to have one layer selected but edit the filter of another layer.
The FilterTool code was updated to use the filter's drawable if editing.
*Prevents editing if multiple layers are selected.
This is a current limitation of the filter tool itself, but it was causing issues with NDE.
*If an XCF with a filter from a third-party plug-in is loaded, the filter won't be
created if the user doesn't have it installed.
Note that GEGL still throws a lot of warnings about missing properties - not sure how to resolve that.
*Refresh drawable when finished editing a filter to fix issue with lingering preview splits
*Fix issue with loading more than one filter after XCF format changes
This patch implements an initial form of
non-destructive editing. Filters now stay active
instead of being immediately merged down.
A new column is added to the layer tree view, which
can be clicked to show a pop-over menu.
Filters can currently be hidden/shown, edited, reordered,
deleted, and merged down from this pop-over menu.
Currently, this works on layers and layer selections only.
Plenty of room for improvement!
… 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.
In particular, if painting on a layer whose parent's pixels are locked,
we were blinking an empty lock spot, which is confusing. Now
gimp_item_is_content_locked() will also return the proper item (when
relevant, i.e. when returning TRUE) which is locked. It may or may not
the same item as passed in (it may also be a parent item in particular).
In several GeglOperation filters, it is possible to pick a color. Up to
now, it was only possible to pick a color from the active layer (the one
you run the operation on). With this change, we can also pick in Sample
merged mode, same as Color Picker tool and other color tools.
In GimpDrawableFilter and GimpFilterTool, use an absolute offset
for the split-preview guide position, instead of storing it as a
fraction of the drawable's width/height. The latter could
introduce rounding error, which would result in wrong coordinates
when converted back to an absolute offset.
Right now I don't change the logics of any of the tools, except that the
GimpTool class now stores a list of drawables instead of a single
drawable. This can be later used on a case-by-case basis to make various
tools actually work on multiple drawables.
In gimp_filter_tool_real_config_notify(), make sure the incoming
pspec in not NULL before accessing it.
gimp_operation_tool_aux_input_notify() may emit "notify" on the
config object with a NULL pspec.
As per commit ed7ea51fb7, reintroduce
the "Fade" functionality for filters, by incorporating it directly
into GimpFilterTool.
Add "mode" and "opacity" options to GimpOperationSettings, and add
a corresponding "Fade" expander to the GimpFilterTool dialog
allowing to control them.
Reintroduce the FADE layer-mode context, and use it to mark the
layer modes avaialable for fading.
Remove the common operation settings from GimpFilterOptions, and
instead, in GimpFilterTool, store these settings in the operation's
config object, which is now a GimpOperationSettings subclass, as
per last commit.
Add a new GimpOperationSettings class, to be used as a base class
for all operation-config types. The class provides options common
to all operations (namely, the clipping mode, input region, and
color options), which were previously stored in GimpFilterOptions,
and were therefore bound to the filter tool, instead of being
stored as part of the operation settings; as a result, these
options would have no effect when reapplying a filter, or when
restoring a preset.
The GimpOperationSettings options do not affect the operation
node, but rather the associated GimpDrawableFilter object. The
class provides a gimp_operation_settings_sync_drawable_filter()
function, which applies the options to the filter.
Modify all custom and auto-generated operation-config types to
derive from GimpOperationSettings, and modify the GimpConfig
functions of the former to account for the GimpOperationSettings
properties, using a set of protected functions provided by the
class.
... which determines if a node's operation-class has a specific
key, and can be used instead of gimp_gegl_node_get_key() when only
existence is important, to avoid compiler warnings.
Update the rest of the code to use the new function.
In GimpFilterTool, use gimp_drawable_filter_set_preview(), added in
the previous commit, to toggle the filter's preview, instead of
removing and re-adding the filter. This avoids destroying cached
results when disabling the preview, allowing to quickly toggle the
preview on and off to compare the result.
... (used to add one automatically)
In GimpFilterTool and gimp_drawable_apply_operation(), use
gimp_drawable_filter_set_add_alpha() to add an alpha channel when
applying an operation that specifies "needs-alpha" to a drawable
that can have alpha.
Don't disable gegl:color-to-alpha (which has "needs-alpha") when
the drawable doesn't have an alpha channel, if one can be added.
In GimpFilterTool, move all the drawable-filter option setup to a
new gimp_filter_tool_update_filter() function, and call it whenever
the drawable-filter's options need to be updated. This avoids
duplicating logic in various places.
In GimpFilterTool, don't provide a clipping option for layers with
no alpha channel, and always clip the result to the layer bounds,
since the extended regions of the result usually require alpha to
be meaningful.
Similarly to last commit, the ideal solution would be to
automatically add an alpha channel as necessary.
When applying a filter to a layer whose position and size are
locked, avoid resizing the layer to the result size in ADJUST mode.
We do this by always returning GIMP_TRANSFORM_RESIZE_CLIP in
gimp_item_get_clip() when the position is locked, and properly
updating the drawable-filter's clip mode, and the filter-tool's UI,
when the position lock changes.
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...
... which specifies whether to clip the viewport to the canvas
(previously, it would always be clipped). Use the appropriate
value in all callers, depending on the shell's "show all" mode. In
particular, this commit avoids clipping the image projection's
priority rect to the canvas in "show all" mode.
Remove the special clipping-mode handling for channels throughout
the transform (and drawable-filter) code, and rather use
gimp_item_get_clip(), added in the previous commit, instead. As
mentioned in the previous commit, we only modify the clipping mode
in top-level code, while having lower-level code use the clipping
mode as-is. This not only hides the actual clipping-mode logic
from the transform code, but, in particular, allows code performing
transformation internally to use arbitrary clipping modes.
Also, this commit fixes a bunch of PDB bugs all over the place :)
In GimpFilterTool, add a new "clipping" option, which can be either
Adjust or Clip. This option is controllable for layers, when
there's no selection mask.
When set to Adjust, which is used by default, the filter's output
may extent past the drawable's boundary, and the drawable will be
resized to match the output when committed.
Don't clear the preset combo right after a preset was selected.
Instead, clear it as soon as any change is made to the settings in the
dialog. This way the last chosen preset's name stays in the combo as
long as the current settings are identical to the preset.
Add a new GimpFilterTool::region_changed() virtual function, which
gets called whenever the filter region changes, either due to a
change to the tool's "region" option, or a change to the image
mask.
Override GimpFilterTool::region_changed() in GimpOperationTool and
GimpOffsetTool, instead of listening to a change to the "region"
option in GimpTool::options_notify(), so that the tools are
properly updated when the image mask changes.
... which takes a GeglNode, and determines if the associated
operation is a point operation.
Use in GimpFilterTool, instead of performing the same check
manually.
In GimpFilterTool, when the filter uses an on-canvas controller,
provide a toggle in the tool's filter-options dialog allowing to
toggle the controller's visibility. This allows getting the
controller out of the way when unneeded.
In GimpFilterTool, show the region combo when applying a non-point
op, as well as when applying a position-dependent point op. The
result of non-point ops may depend on the choice of input region,
even if the op is not position-dependent.
In all tools, when the current item can't be edited due to its lock
mask, use gimp_tools_blink_lock_box(), added in the previous
commit,to blink the lock box of the corresponding dockable, in
addition to showing an error message in the status bar, to hint at
the source of the error.
Move the call to gimp_filter_tool_disable_color_picking() from the
filter-tool's dialog "unmap" handler to gimp_filter_tool_halt().
Since commit ec80a88513, we
explicitly destroy the GUI when halting the filter tool, which
happens before the dialog's unmap handler is called, which could
potentially result in a dangling pointer to the active color-picker
widget in gimp_filter_tool_disable_color_picking().
In gimp_filter_tool_halt(), explicitly clear the GUI container
before clearing filter_tool->config, since the tool might be halted
during the GUI dialog's delete event, in which case the GUI will
only be implicitly destroyed *after* the function returns. The
destruction of the GUI might fire signals whose handlers rely on
filter_tool->config, so we need to make sure it happens while it's
still alive.
In particular, this fixes a CRITICAL in the threshold tool, which
occurs due to the histogram view's "range-changhed" signal being
fired during its destruction, and its handler accessing
filter_tool->config.
