In gimp_gegl_apply_cached_operation(), add a boolean
connect_src_buffer parameter, which determines whether to connect
the source buffer to the operation-node's input, or to use its
existing input. In gimp_drawable_merge_filter(), pass FALSE for
connect_src_buffer, so that the existing filter-node input is used.
This produces an equivalent result, however, it avoids invalidating
the filter node, and dropping cached data as a result. In
operations that cache larger areas than the ROI, this avoids
reprocessing already-cached data when processing the rest of the
operation.
Additionally, in gimp_gegl_apply_cached_operation(), use an empty
input for the operation if src_buffer is NULL and
connect_src_buffer is TRUE; previously, we'd use the operation-
node's existing input when src_buffer was NULL. Furthermore, crop
the operation-node's input to the destination rect when crop_input
is TRUE, even if connect_src_buffer is FALSE.
(cherry picked from commit 11629fde66)
Add a "gboolean edge_lock" parameter to GimpChannel::feather() and a
"Selected areas continue outside the image" toggle to the "Feather
Selection" dialog, just like they exist for shrink selection and
border selection. At the end, convert the boolean to the right abyss
policy for gegl:gaussian-blur.
(cherry picked from commit aace6b179b)
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.
... so that the transformed boundary is properly clipped.
Adjust the boundary-size algorithms to operate on arbitrary
polygons.
Avoid using gimp_matrix3_will_explode() in
gimp_drawable_transform_buffer_affine() and falling back to
cropping the result, and avoid setting the "clip-to-input" property
of gegl:transform. Neither of those in needed anymore.
This effectively reverts the app/ part of commit
768d06614f. The next commit revets
the libgimpmath/ part.
Add a composite_space parameter to gimp_gegl_create_flatten_node()
and gimp_gegl_apply_flatten(), which controld the color space --
linear or perceptual RGB -- used for the operation (instead of
hardcoding it to linear).
When removing a layer's alpha channel, use the layer's composite
space for the flattening. When flattening an image, use the bottom
layer's composite space. Keep using linear space when creating a
channel or a mask from a drawable with alpha.
...instead of transforming it
Add gimp_matrix3_will_explode() which determines if a transform
matrix will blow up something in a rectangle to infinity, and use
the function so set both the GIMP and GEGL code paths to clip the
transform to the input size.
instead of the feather parameter.
The BORDER_STYLE_HARD and BORDER_STYLE_FEATHERED styles are implemented
using the "gimp:border" operation, as was done previously. The
BORDER_STYLE_SMOOTH style is implemented by performing a "gimp:grow" and
a "gimp:shrink", and subtracting the shrunk image from the grown image
using "gegl:substract".
gimp_channel_border() is modified to pass either BORDER_STYLE_HARD or
BORDER_STYLE_FEATHER, depending on its feather parameter, to maintain
the current behavior. The next commit replaces it with a style
parameter as well.
Mass parameter alignment changes to gimp-gegl-apply-operation.h. Sigh...
This operation assigns to each pixel the minimum of the
maxima of all paths from it to the outside, as if the
input image represents a height map, and the operation
floods it with water.
- change start() and set_text() to use "format" and "..." instead of
"message", allowing to format progress messages in place
- s/cancelable/cancellable/
- move "cancellable" to be the second argument of start()
In gimp_drawable_merge_filter(), use that feature to make filter
applying cancelable. Stop projection rendering first, because we have
to run the event loop manually in order to receive input for
canceling, but we don't want the projection to be constructed from
that manual loop running.
which does the same as gimp_gegl_apply_operation() but takes
additional arguments which are a cache buffer and a list of rectangles
that specify the already computed region in the cache buffer.
gimp_gegl_apply_feather(): add a "dest_rect" parameter to restrict
the feather area. Pass the selection bounds plus the feather radius.
For consistency, newly add gimp_gegl_apply_border,grow,shrink() and use
them in gimpchannel.c
and invert masks using invert-linear and other drawables using
invert-gamma. drawable_invert_cmd_callback() still always uses
invert-gamma even though it can be used on layer masks.
