Make sure to update the drawable after committing the Warp tool, if
high-quality-preview is disabled, and we use a non-nearest sampler.
Necessary after commit d928a80b7f.
Add a "real-time preview" option to the warp tool, which, when
toggled, causes the preview to be rendered synchronously during
motion. This is slower, but gives better feedback.
The "spacing" option of the warp tool used to be handled by the
gegl:warp op, and have little effect. Instead, implement it in the
warp tool directly, having the same effect as the other paint
tools.
Having a properly-working "spacing" option allows us to use EXACT
motion mode without cirppling down performance, which means that
the stroke now follows the pointer exactly, even when processing
takes a while.
Decrease the default "spacing" value to 10.
In the warp tool, use the gegl:map-relative node to calculate the
invalidated drawable area when the displacement field changes, to
account for box filtering.
In the warp tool, set the drawable-filter's crop area to the
combined stroke bounds, so that, when comitting the tool, only this
area is processed, instead of the entire drawable area.
In the warp tool, when the warp is empty and the current behavior
has no effect as a result (i.e., when it's ERASE or SMOOTH), show
an error message in the status bar, and blink the behavior combo
widget in the tool options, to hint at the source of the error.
In the warp tool, when no stroke events are selected, blink the
stroke frame widget in the tool options, in addition to showing an
error message in the status bar, to hint at the source of the
error.
The enumerators of the GimpWarpBehavior enum, except for MOVE, had
a GEGL_ prefix, rather than a GIMP_ prefix, for some reason.
Change all of them to GIMP_.
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.
In the warp tool, don't commit a trivial (empty) transform. This
is especially important now that exiting the tool through undo
causes it to get comitted (... with a trivial transform).
... changing layers and warping layer B
Add a new GimpToolControl::dirty_action field, which specifies the
tool action to perform when the a dirty event matching the tool
control's dirty mask occurs; this field defaults to HALT. Apply
this action to the active tool in tool-manager in response to a
matching dirty event, instead of unconditionally halting the tool.
Likewise, use this action to stop the active tool in response to a
button-press event on a different drawable in the same image.
Set the dirty action of the gradient and warp tools to COMMIT, so
that they get comitted, rather than stopped, in cases such as
switching layers (including switching to/from quick-mask mode),
and, for the warp tool, changing the selection.
Add a crop_input parameter to gimp_gegl_apply_[cached_]operation().
When TRUE, the functions crop the op's input to the destination
rect. This is particularly useful for functions that process the
entire input in one go (by means of get_cached_region()). See the
next commit.
Pass crop_input = FALSE at all call sites for now, to keep the
current behavior.
which is just a #define to g_assert for now, but can now easily be
turned into something that does some nicer debugging using our new
stack trace infrastructure. This commit also reverts all constructed()
functions to use assert again.
...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
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);
Call HALT generically in gimp_tool_control() after calling COMMIT, and
remove all hacks in tools that call both COMMIT and HALT or call
halt() from commit().
Some tools interact with their subclasses (e.g. filter tool and
operation tool), and it's essential that COMMIT runs through the
entire class hierarchy before HALT.
Probably breaks something, please test.
to ::can_undo() and ::can_redo(). They still return description
strings and the new naming is slightly off :) but get_undo_desc() will
be needed for something else soon, and half of the time the functions
are indeed used to check whether there are undo/redo staps at all.
... to the warp tool
The interpolation and abyss policy options control the sampler type
and abyss policy of the map-relative node. The high quality preview
option determines whether to use the same sampler for map-relative
during preview as the one used during commit, or whether to use a
fast nearest-neighbor sampler.
A bit too much? Maybe :)
... and to disable/control the rate of the periodic stroke.
The warp tool is now fast enough to enable stroking directly in
the motion handler, which gives better-quality response to motion
than stroking periodically. It's not quite fast enough to enable
exact motion, though :/
Allow individually enabling/disabling stroking during motion and
periodically, and allow controlling the rate of the periodical
stroke.
When using the MOVE behavior, don't append the current cursor
position to the stroke path in the timeout proc if the cursor
hasn't moved since last time. It has no effect, except for
requiring an unnecessary update.
When undoing a warp stroke, don't disconnect the current warp node
from its predecessor; rather, keep the graph as-is, and only
reconnect the render_node to the previous node. This avoids
invalidating the undone node, so that redoing it (which, likewise,
only involves reconnecting the render_node) doesn't require
reprocessing, making it much faster.
The spacing parameter controls the stroke spacing of the warp op.
It's similar, but not identical, to the brush spacing parameter of
the paint tools. It provides a tradeoff between speed and quality.
Change the UI range of the hardness parameter from [0, 1] to [0, 100],
to match the other parameters.
Remove all stock items added since 2.8, restore accidentially removed
ones, and rename the newly added GIMP_STOCK_* defines to GIMP_ICON_*.
(will move to having GIMP_ICON_* defines instead of magic hardcoded
strings for all icons).
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
Add generic tool actions for spacing, hardness and force, and the
GimpToolControl infrasctructure to redirect them to tool-specific
actions. Add tool-specific actions for GimpBrushTool, GimpMybrushTool
and GimpWarpTool as redirect targets. Also fix some existing tool
action callbacks to use the right increase/decrease steps.
