Promote the precision of generated brushes to 32-bit float, and
modify brush preview generation, and gimpbrushcore-loops, to handle
float brushes. This avoids posterization in large brushes.
Note that non-generated brushes are still uint8.
Add support for reflecting brushes as part of their transformation.
The reflection is performed as the last step of the transformation,
across the vertical axis.
The option to reflect the brush is not exposed in the UI, or
through the PDB, but is intended to be used for linking the brush
transformation to the view transformation, in the next commit.
When copying a generated brush, copy its "spacing" property, in
addition to the other properties, which hasn't been previously
copied by ::duplicate().
Finish up commit 17583ff04a, which
ported GimpGradient from ::duplicate() to ::copy(), by doing the
same for the rest of the GimpData subclasses that implement
::duplicate().
We still keep GimpData's ::duplicate() virtual function around,
even though it now points to the default implementation (which uses
::copy()) for all subclasses, since ::copy() is stronger than
::duplicate(), and we might want to have certain GimpData types
that are duplicatable, but not copyable.
More than 2000 lines of code less in app/, instead of
if (instance->member)
{
g_object_unref/g_free/g_whatever (instance->member);
instance->member = NULL;
}
we now simply use
g_clear_object/pointer (&instance->member);
Check if the brush parameters match the identity parameters, and
return the original brush mask/pixmap if they do, in the actual
mask/pixmap transformation virtual functions, instead of in their
wrappers. While the identity parameters for raster brushes are
always scale=1, aspect-ratio=0, angle=0, and hardness=1, for
generated brushes they depend on the specific brush
parameterization.
...are not submitted to respective Tool Options sliders
Treat brush angle and aspect ratio like all other paint options values
that can be linked to brush defaults and take their default values
from the brush. They were special casing their defaults to constants,
and GimpBrushGenerated was adding the passed dynamic radius and aspect
values to its own. This was totally incomprehensible.
Now GimpBrushGenerated's transform_size() and transform_mask()
implementations just translate between these APIs value ranges and the
brush's own value range and only use the passed values (not the
brush's native values), which makes the editor <-> tool options
interaction and the painted brush shape predictable.
Also connect the active brush's property notifications to the paint
options properties, so the paint options follow a brush edit live if
the respective "linked" toggles are checked.
And some cleanup.
They are unreliable because every type checking cast discards them,
they are useless anyway, visual clutter, added inconsistently, and
generally suck. Wanted to do this a long time ago, it was a bad idea
in the first place.
Change gimp_brush_generated_get_half_size() to get_size() and
calculate its exact size in float. This is really a minor change that
seems to work well.
- don't include <gdk-pixbuf/gdk-pixbuf.h> in headers in app/
- instead, include it in many .c files instead of <glib-object.h>,
finally acknowledging the fact that app/ depends on gdk-pixbuf almost
globally
- fix up includes as if libgimpbase depended in GIO, which it soon will
Fix the places that passed the color by either temp_buf_data_clear()
or memset(), and assign x and y manually, they are going to vanish
completely soon.
For generated brushes, dynamic input is applied on top of the set hardness as a factor.
For pixmaps, it influences the amount of blur applied to the stamp. Be warned, process is slow
for large pixmaps. The odd feature previously advertised as hardness is left in but disabled.
If I figure out what it should be exposed as, it might be made available again.
Begin to consider GimpObject::name as private and always use
gimp_object_get_name(). Change gimp_object_get_name() to take an
untyped pointer so we don't have to do so awfully many casts. There is
a runtime check for the type inside the function anyway.

Bug 520078 – Rotate brushes
Applied patch from Alexia Death:
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.c
* app/core/gimpbrush-transform.[ch]: affine transformations for
brushes. So far only scaling and rotation is supported. The
transformation is done using nearest-neighbour. This is a
regression and we need to add back interpolation before the next
release.
* app/paint/gimpsmudge.c
* app/paint/gimppaintoptions.[ch]
* app/paint/gimpbrushcore.[ch]: allow to control the brush
rotation angle.
* app/tools/gimppaintoptions-gui.c
* app/tools/gimpbrushtool.c: added UI for controlling the
brush rotation angle.
* app/actions/tools-actions.c
* app/actions/tools-commands.[ch]: add actions for controlling
the
brush rotation angle.

Made brushes upscalable by using scale_region. Downscaling still
uses functions in app/base/brush-scale.c (because of better
performance). Parametric brushes of course recalculates masks
instead of using bitmap scaling. Fixes bug #65030.
* app/core/gimpbrush.[ch]: Added a private scale_buf method which
uses scale_region (with GIMP_INTERPOLATION_LINEAR) to scale its
masks and pixmaps. Also added public virtual method scale_size to
GimpBrush (overridden by GimpBrushGenerated) which calculates the
buffer sizes for a given brush scaled with a given scale.
* app/core/gimpbrushgenerated.c: Implemented the new scale_size
method inherited from GimpBrush, and modified
gimp_brush_generated_calc to use this helper function.
* app/tools/gimppaintoptions-gui.c (gimp_paint_options_gui): Made
the brush Scale-slider logarithmic.
* app/paint/gimppaintoptions.c (gimp_paint_options_class_init):
Changed Scale scale to [0.0, 10.0].
* app/paint/gimpbrushcore.c:
(gimp_brush_core_calc_brush_size): Refactored 'get brush size' code
to where it belongs, in GimpBrush-classes, and allowed scales
larger than 1.0.
