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.
... 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.
When merging a drawable filter, we call
gimp_gegl_apply_cached_operation() on a node that's part of the
drawable's filter stack graph. The function rewires the node's
input, and doesn't restore its original input connection before
returning, leaving the graph in an inconsistent state. Currently,
this doesn't matter, since we remove the filter right after that,
but the next commit expects the filter stack graph to remain
consistent.
Remember the original source node of "operation" in
gimp_gegl_apply_cached_operation(), and restore it upon exit, to
fix that.
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.
in which case the function just does nothing on the passed operation's
input and expects it to be already conntected to something. Also allow
to pass an operation that is already part of another graph.
