Avoid unnecessary calls to gimp_temp_buf_data_clear() in various
places, where either the entire buffer is being written to, or most
of it is, only requiring clearing the edges.
(cherry picked from commit 9d19e804ed)
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.

... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
Replace the "lock brush size to zoom" paint option with a "lock
brush to view" option, which links the entire brush transform to
the view transform, so that the brush remains invariant in display
space under scaling, rotation, and reflection.
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.
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.
You can now set any paint tool to mirror painting relatively
horizontal/vertical axis or a central point (any combination of these 3
symmetries).
This has been implemented as a new multi-stroke core, where every stroke
is actually handled as a multi-stroke (default of size 1).
This is also the first usage of custom guides for symmetry guiding.
Current version has to be activated in the playground.
- 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.
It's likely that the removed call and function were causing
random drawing artefacts, but as this was once in a blue
moon bug, I have just a guess to go by however, testing
revealed no regressions, so pushing.
such as masks and outlines. The cache is currently very stupid and
only cacheds the last transformed object. Add caches to GimpBrush for
its mask, its pixmap and its boundary, and remove the same caches and
a ton of members from GimpBrushCore. This involves adding lots of
const qualifiers because GimpBrush returns const pointers now for
trasnformed stuff.
