In gimp:mask-components, add an "alpha" property, which controls
the masked-in alpha value in case there's no aux buffer. Set it to
0 by default, so that gimp:mask-components behaves normally in the
absence of an aux buffer (as if the aux buffer was empty). Set it
to 1 in the image's visible-mask node, to maintain the current
alpha-component visibility behavior.
This fixes incorrect results when the output bounding box of a
drawable filter is smaller than the drawable, which can lead to a
NULL aux buffer being fed to the filter's gimp:mask-components
node.
In GimpOperationLayerMode and GimpOperationReplace, make sure we
don't return a NULL output buffer, or forward a NULL input buffer,
but rather create an appropriate empty buffer in this case. This
avoids wrong results when the layer-mode op's output is connected
to the aux input of a subsequent op, as a result of the op behaving
differently with a NULL aux buffer (in particular, this can happen
when a drawable filter's output bounding box is smaller than the
drawable.)
There should never be an image using GIMP_TRC_PERCEPTUAL, but things
should work if one is encountered anyway.
In the Image -> Precision menu and the Convert Precision dialog, have
menu items / radio buttons for both non-linear and perceptual, but
hide the perceptual choice unless the image is in perceptual TRC mode.
This should eliminate the possibility to create perceptual TRC images
from the GUI.
...when generating "TRC variants"
When creating a new profile with different TRC from an existing
profile, keep all the original profile's description, model,
manufacturer and copyright strings around, but prefix them with "GIMP
from " or similar to indicate that they are different. Also make sure
we don't prefix strings with GIMP stuff multiple times when profiles
are generated repeatedly.
gimp_image_convert_precision(): if the conversion changes the TRC and
the image's profile is a built-in profile, don't create a profile from
it but instead simply use the new TRC's built-in profile.
Add "gboolean push_undo" parameters to gimp_image_parasite_attach()
and _detach() and use the API also from undo, instead of implementing
attaching/removing manually and forgetting about the signals.
Fixes updating of the image properties color profile page.
gimp_image_parasite_attach(): when we detected that a builtin profile
is about to be attached, actually bail out after removing the old
profile, instead of continuing to attaching the builtin profile
anyway. Gah...
This commit adds support for moving together an intersecting pair
of guides using the Move tool, by dragging the guides at their
point of intersection. This is useful when the guides are used to
mark a point, rather than a pair of lines (e.g., as is the case for
the mandala symmetry guides, which mark the symmetry's point of
origin).
Add gimp_image_pick_guides(), which can return a set of guides,
rather than a single guide. The API allows an arbitrary set of
guides to be returned, but, in practice, at most two intersecting
guides are returned, as per the above.
In GimpMoveTool and GimpGuideTool, add support for moving multiple
guides together, and, in GimpMoveTool, use gimp_image_pick_guides()
to potentially pick multiple guides.
...to the Configure Keyboard Shortcuts dialog
Add the button, based on an old patch from Sven Neumann, and make the
buttons in the keyboard shortcuts and input devices dialogs look and
behave the same.
In gimp_gegl_apply_[cached_]operation(), add support for output
buffers whose extent's top-left corner is not (0, 0). This is
needed by the previous commit.
In GimpSourceCore, when applying a symmetry transform to the source
content, combine the transform op with translation to the paint-
buffer coordinates, so that subclasses (namely, GimpClone and
GimpHeal) can use the op to apply the transformation directly from
the source buffer to the paint buffer in a single step. This is
both more efficient, and avoids incorrect symmetry transforms when
the paint buffer is cropped to the bounds of the drawable.
Remove the GimpSymmetry::get_operation() virtual function, and
instead implement gimp_symmetry_get_operation() by returning an
appropriate gegl:transform node based on the matrix returned by
gimp_symmetry_get_matrix(). The returned node is owned by the
caller; since we no longer use the node's identity for caching
trnasformed brushes, we no longer cache the transformation nodes.
Remove the function's paint_width and paint_height parameters, and
instead return a transformation that should be applied at the
center of the brush. This simplifies the application of the
transformation in the Clone and Heal tools, as per the next commit.
Remove the implementation of GimpSymmetry::get_operation() from all
its subclasses, which should now only implement
GimpSymmetry::get_transform().
Add GimpPaintbrush::get_color_history_color() virtual function,
which should return the color to be added to the color history upon
painting, if any. The default implementation returns the
foreground color, when not using a pixmap brush or color-from-
gradient.
Override this function in GimpEraser, to return the background
color when the affected drawable has no alpha channel, instead of
overriding GimpPaintCore::paint() for this purpose. This avoids
erroneously adding both the background and foreground colors to the
history.
As suggested by LRN, change gimp_sigfatal_handler() on Windows to
dstinguish between fatal and non-fatal exceptions so we don't abort on
each minor hickup.
Further improvements should load screenshots in a thread, especially
since we are loading from a URL taken from metadata, so it makes the GUI
non-responsive for a bit too long. But this is a first working version
for now.
This first version of this API only returns the default screenshot.
Further improvements should allow to return all the available extension
screenshots.
Use GtkGrid instead of GtkBox (docs says GtkBox will eventually go
away). Also remove this horrible frame in a frame (though GUI is still
not perfect yet). Finally fix the "extension" object data.
In GimpClone and GimpHeal, use gimp_gegl_apply_operation(), instead
of gegl_node_process(), to apply the symmetry transform, which both
performs chunking and avoids aliasing problems.
...-last positioned- monitor
Use gimp_dialog_factory_position_dialog() in GimpColormapEditor and
GimpPaletteEditor so the color dialogs appear where they were before.
which is the logic that used to be in color_area_color_clicked()
factored out to proper API. It makes sure that a dialog that was
visible before (and was only hidden not destroyed) appears at the same
point on the same monitor as before. See issue #1093.
In GimpPaintbrush, factor out the code responsible for determining
the current dab's paint parameters and content to a new
GimpPaintbrush::get_paint_params() virtual function.
Derive GimpEraser from GimpPaintbrush, instead of directly from
GimpBrushCore, implementing get_paint_params() appropriately.
This allows GimpEraser to reuse the paint-buffer content across
dabs, improving performance.
Use gimp_symmetry_get_transform() instead of
gimp_symmetry_get_operation() throughout the paint code, where
possible. This allows us to combine the symmetry transform with
the ordinary brush transform, simplifying the code, improving
performance, and avoiding multiple resamplings. This also fixes
the paint-buffer size when using mandala symmetry with non-round
brushes, avoiding artifacts.
