Canceling a paint stroke restores the layer and mask (if present) to the
original size if they were expanded during the stroke. The part of
stroke that is outside the layer remains visible though.
In ink tool, if last_blobs is empty, the copy of blobs present in
last_blobs and blobs_to_render was same. Due to this, when layer
boundary is expanded, we move same blobs twice. Due to this a straight
line was drawn when starting painting from outside layer boundary. Fixed
the issue by storing a duplicate version in blobs_to_render. Updated
free part accordingly.
In layer expansion if user is trying to draw outside the layer boundary
with expand option turned on but the "Lock position and size" enabled,
the lock square will be blinked. If user is painting on layer mask, the
corresponding layer's lock will be blinked. It will be blinked only
once per stroke.
When resizing drawable for dynamic layers, the resize drawable function
would push Modified Layer/Channel item to undo stack. Initially, I was
checking if the drawable is being painted upon and used it to disable
the undo, but this when using resizing layers with layer mask, even if
mask is being painted upon, we still want to resize the main layer and
vice versa. But the main layer is not being painted upon so it would
push the undo to stack. To prevent this, I was using
gimp_drawable_paint_start before resizing, but this method is very
inefficient, as this function duplicates buffers. So added a new member
to drawable->private that will store weather to push undo or not.
Added option to tool settings that will decide how newly created parts
of layer and layer mask should be filled. For layer, same options are
provided as present in "Set Layer Boundary Size" dialog. For layer mask,
first two options from "Add a Mask to the Layer" i.e. "White" and
"Black" are added.
This commit changes gimp_channel_resize function to actually use the
passed fill type instead of using hardcoded GIMP_FILL_TRANSPARENT.
Hardcoding this value if required should be done in function calling
this function (which is already the case with all the instances already
present afaik).
Modified gimp_gegl_buffer_resize function to add three new parameters,
pattern, pattern_offset_x and pattern_offset_y. If pattern is not NULL,
then we set the pattern of buffet to this value. Like in
gimp_gegl_buffer_resize function, this logic is mostly copied from
gimp_drawable_fill_buffer function with minor changes.
This function returns resized version of the input buffer. It also takes
in a color argument. The layer background will be filled with this
color. Fill background logic is similar to gimp_drawable_fill_buffer.
The lock in the layers tab only sets lock for the actual layer and not
for its mask, so also check the lock on the actual layer and not just on
the mask when editing layer mask.
Everytime the layer expands, if the undo extents are empty, then make
them non zero. If the undo extents are zero, then user will not be able
to undo the expansion of the layer. This is perticularly required by
MyPaintBrush as just clicking the image without any motion does not draw
anything, but expands layer if required.
This function returns TRUE if the drawable is expanded. Otherwise, it
will return FALSE. This removes the need to check width and height of
the drawable to infer the same.
Made `gimp_image_editor_image_flush` and
`gimp_image_editor_image_flush_idle` functions idle. For expanding
layers dynamically, we need to use gimp_image_flush funtion from the
paint therad. The gimp_image_flush eventually calls these functions.
When painting the layers with a layer mask, if the layer need to be
expanded, the layer mask is also expanded with it. The same is done even
if layer mask is being painted upon.
Undo works with these layers by adding resizing of both the layer and
mask to the undo group if the layer is resized during painting.
Now layers will expand when trying to draw beyond layer borders with ink tool.
Tool options similar to paint tools have been added (expand_use and
expand_amount).
When painting with "Expand Layers" option turned on but "show all"
turned off, layer will not expand beyond image borders.
Layer will not expand if "Lock size and postion" is turned on.
Created a separate function gimp_paint_core_expand_drawable that handles
layer expansion while painting. The gimp_brush_core_get_buffer function
now uses this function to expand drawable. It has been separated so that
it can be reused for ink tool.
When painting with paintbrush tool, the borders of active layer will
automatically expand to accomodate the stroke. The undo does not work
with expanding layers.
This patch adds better handling for group begin and end markers
within ASE palettes. As a result, this fixes an issue where the last
color was not imported in some ASE files without groups.
Additionally, this guarantees that colors are imported using 4 bytes

When compiled with -Werror=strict-aliasing, the build fails
on this line due to converting pointer datatypes.
This patch switches to using memcpy () instead.
Currently we only use and retain "critical" PNG chunks,
discarding any safe-to-copy but non-image chunks.
This adds code to store them as parasites and then
include them on export, thus preventing loss of data.
when loading a BMP image with an invalid compression value.
The invalid compression check was missing a goto out (error exit)
causing the GError to be overwritten, which caused a GLib warning.
We add the missing goto statement here.
Overwriting a GIF animation results in loss of frames if a previous export turned off
animations.
This sets a parasite on import which we check for on overwrite. If it was an
animation originally, we overwrite as an animation as well.
