Fix gimp:mask-components to use full-oapcity value for the alpha
component when it's masked-in and there's no "aux" input, so that
the image is rendered with full opacity when the alpha channel's
visiblity is toggled off, as per bug #143315.
In GimpTransformGridTool, fix weak-pointer initialization for the
out-of-bounds selection-boundary canvas item, to avoid a CRITICAL
when initializing the tool in transform-selection mode for a fully
out-of-bounds selection, and a subsequent segfault when re-
initializing the tool.
Add "Constrain handles" and "Around center" options to the
perspective-transform tool's GUI, which are similar to the
corresponding options of the unified-transform tool. Both of these
options can already be controlled using Shift and Ctrl,
respectively, through the transform-grid widget, so we might as
well provide GUI toggles for them.
In GimpToolTransformGrid, use the transformed center-point of the
original polygon as the position of the center-point handle, and as
a snapping point for the pivot when "cornersnap" is TRUE, instead
of using the center-point of the transformed polygon. These two
points are different for non-affine transformations.
Furthermore, when "use-pivot-handle" is FALSE, use the center-
point as the reference point when transforming around the pivot,
instead of the pivot itself, which might not be set. In
particular, this fixes transformation around the pivot in the
perspective tool.
Don't explicitly set the center-point as the pivot in the scale
tool, since this commit makes it unnecessary.
In gimp_pickable_contiguous_region_by_color(), add a small epsilon
to the threshold value, to allow for small errors due to the input
color and pickable pixel-colors being converted to the common
format through different paths.
While we *could* special-case threshold == 0 when the input color
comes from the same pickable, as is the case for the select-by-
color tool, and perform an exact comparison in the original format,
in the more general case the input color can come from an arbitrary
source, such as a plug-in.
In gimp_gegl_create_flatten_node(), explicitly set the output
format of the background gegl:color node according to the composite
space, so that no conversion is required during compositing.
In gimp_image_merge_layers() -- the internal function used by the
various layer-merging/flattenning functions -- process the merged-
layer graph in chunks, using gimp_gegl_apply_operation(), instead
of in one go, using gegl_node_blit_buffer(). Processing in chunks
better utilizes the cache, since it reduces the size of
intermediate buffers, reducing the chances of hitting the swap when
merging large images (see, for example, issue #3012.)
Additionally, this allows us to show progress indication. Have the
relevant gimpimage-merge functions take a GimpProgress, and pass it
down to gimp_image_merge_layers(). Adapt all callers.
Streamline the various action_data_get_foo() functions, by having
each function only match the action data directly against its
specific type(s), and use the other functions to match the action
data against their corresponding types, instead of having each
function directly exhaust all possible matches.
Other than reducing depulication, it fixes certain cases in which
some action_data_get_foo() functions would fail to find a match,
even though one exists, since they failed to exhaust all the
options.
In GimpSmudge, avoid copying the brush's dab to the paint buffer
when using a pixmap brush if the flow parameter is 0 -- it has no
effect in this case.
Reimplement gimp_brush_core_color_area_with_pixmap(), which copies
the brush's dab to the paint buffer when using a pixmap brush, in
terms of gimp-gegl-loops. This simplifies the functions,
parallelizes processing, and transparently handles float brushes.
Replace the "mode" parameter of the function with an "apply_mask"
parameter, which specifies whether to apply the brush's mask to
the dab as part of copying. Avoid applying the mask in
GimpPaintbrush; previously, we would erroneously apply the mask
twice when using the paintbrush tool: once when copying the
dab to the paint buffer, and again when pasting the paint buffer
to the canvas.
We still apply the mask in GimpSmudge, which results in the same
double-application behavior, however, this might be less practical
to fix.
Just the GimpData::save() and ::copy() part that is needed to
duplicate and rename them, the image-to-pipe logic from the export
plug-in remains to be ported.
Commit dc069e424a removed the
assumption that 1-bpp PCX files are B&W, in favor of using the
provided palette, which is (supposedly?) the correct behavior.
However, there are evidently B&W files that do not specify a
palette, resulting in an all-black image (i.e., a 2-color indexed
image, whose both palette entries are black). Since other
software, including older versions of GIMP, load such files
"correctly", let's fix this by falling back to a B&W palette when
the provded palette is uniform.
Replace the use of the deprecated GeglNode::dont-cache property,
and GeglOperationClass::no_cache field, with GeglNode::cache-policy
and GeglOperationClass::cache_policy, respectively.
See commit gegl@7f24430cda0d8c3eff311868823d445edc2a4e12.
The GUI implementation of gimp_wait() relies on the ability to run
plug-ins (namely, the busy-dialog plug-in) without entering the
main loop. This prohibits the said plug-ins from making any PDB
calls, which would result in a deadlock. However, we're currently
calling gimp_gimprc_query() to fetch the prefer-dark-theme option
during gimp_ui_init() (or any time the theme.css file changes).
Instead, communicate this preference through the theme.css file
itself, by writing a /* prefer-dark-theme */ comment to the file
when the option is set. Yes, it's a bit of a hack :P
- don't clear the names of the individual brushes, we need them for
a load -> save roundtrip
- for the same reason, and for convenience, store the parameter string
in the object
- clean up gimp_brush_pipe_finalize()
gimp_widget_flush_expose() has been removed since commit 3089a20167.
I now reimplemented it by simply checking if event sources are waiting
to be processed.
This was heavily needed as the statusbar was not showing any progress
(at least on highly demanding process, such as saving or loading files),
and therefore we were stuck with a seamingly frozen GUI.
Despite the name, this does not apply to a widget in particular anymore,
but to the whole program events.
In gimppaintcore-loops, unsuppress the
COMBINE_PAINT_MASK_TO_CANVAS_BUFFER algorithm (partially
reverts commit b717ead1abd487f663668ac131883dff0ffe4557.)
In gimp_paint_core_paste() it's always used together with
CANVAS_BUFFER_TO_PAINT_BUF_ALPHA, which matches a combined
algorithm, preventing it from being called, however, it can still
be called through gimp_paint_core_replace(), which uses it
together with CANVAS_BUFFER_TO_COMP_MASK, which doesn't have a
combined algorithm. We can, however, filter out
CANVAS_BUFFER_TO_PAINT_BUF_ALPHA whenver
COMBINE_PAINT_MASK_TO_CANVAS_BUFFER is matched (since the combined
algorithm will be matched beforehand when both algorithms are
included).
In gimp_drawable_filter_sync_affect(), don't mask-out the filter's
alpha component when the drawable doesn't have an alpha channel,
since this is no longer necessary -- we now explicitly convert the
output to the drawable format as part of the graph -- and it
prevents the gimp:mask-components node from becoming a NOP.
In gimp_drawable_get_active_mask(), when the drawable doesn't have
an alpha channel, set or clear the mask's alpha bit, according to
the state of the other bits, so that it never gets in the way of a
fully set/clear mask. The value of the alpha bit doesn't matter
when there's no alpha channel, however, having a uniform mask
allows us to skip component masking altogether.
Additionally, provide a default implementation for
GimpDrawable::get_active_mask() which returns a full mask, and
remove the equivalent implementation for GimpChannel.
Remove the mask_components_onto() gimppaintcore-loops function, and
the GimpPaintCore::comp_buffer member. Instead, in
gimp_paint_core_paste() and gimp_paint_core_replace(), use the
MASK_COMPONENTS algorithm, added in the previous commit.
In gimppaintcore-loops, add a new MASK_COMPONENTS algorithm, which
masks the output of compositing into the destination buffer,
according to a component mask. The algorithm uses the same code as
gimp:mask-comopnents, and can be used as part of a
gimp_paint_core_loops_process() pipeline, instead of using a
separate function.
In gimppaintcore-loops, add a CompBuffer algorithm helper-class,
which provides access to the output buffer used for compositing,
to be used by the DO_LAYER_BLEND algorithm instead of the
destination buffer.
CompVuffer itself doesn't provide the storage for the buffer; this
is rather the responsibility of the algorithms that use it. The
TempCompBuffer algorithm helper-class provides temporary storage
for the compositing buffer, and can be used by algorithms that need
a temporary buffer.
