In gimp_drawable_real_apply_buffer(), use GimpChunkIterator to blit
the applicator's output to the drawable's buffer in chunks, to
minimize the space used for intermediate results.
Remove gimp_drawable_replace_buffer(), which is no longer used
anywhere since commits ddb69b77a7 and
3451ffb62c. This eliminates
redundancy, since all compositing is now done through the layer-
mode code.
Furthermore, gimp_drawable_replace_buffer() used the drawable's
active-component array, whose layout depends on the image mode, as
an argument to gimp_gegl_replace(), which always expects an RGBA
component array, resulting in broken component masking in non-RGB
images.
Remove the use_split_preview and use_result_cache parameters of
gimp_applicator_new(), and allow enabling/disabling the cache
(through gimp_applicator_set_cache()) and the preview crop (through
gimp_applicator_set_preview()) after construction.
Move the preview crop node after the result cache, and remove the
separate preview cache node. This eliminates an extra cache
buffer, reducing the space consumed by filters, and speeds up split
preview, since the cached result now includes the output
compositing.
This commit completely removes the "Edit -> Fade..." feature,
because...
- The main reason is that "fade" requires us to keep two buffers,
instead of one, for each fadeable undo step, doubling (or worse,
since the extra buffer might have higher precision than the
drawable) the space consumed by these steps. This has notable
impact when editing large images. This overhead is incurred even
when not actually using "fade", and since it seems to be very
rarely used, this is too wasteful.
- "Fade" is broken in 2.10: when comitting a filter, we copy the
cached parts of the result into the apply buffer. However, the
result cache sits after the mode node, while the apply buffer
should contain the result of the filter *before* the mode node,
which can lead to wrong results in the general case.
- The same behavior can be trivially achieved "manually", by
duplicating the layer, editing the duplicate, and changing its
opacity/mode.
- If we really want this feature, now that most filters are GEGL
ops, it makes more sense to just add opacity/mode options to the
filter tool, instead of having this be a separate step.
In gimp_drawable_real_{apply,replace}_buffer(), bail if the
applcation region, after intersection with the drawable and mask
extents, is empty. This avoids trying to create a GeglBuffer with
negative width/height.
... (some sort of corruption)
In gimp_drawable_real_replace_buffer(), adjust the processed buffer
and mask_buffer regions according to the changes made to the
application region, as calculated by intersecting it with the
drawable and mask extents. This fixes wrong application position
when painting using the heal, dodge/burn, smudge, or convolve
tools, on a drawable whose origin is above/to the left of the
image's origin, and there's a selection active.
Largely based on a patch by Ell, with the enum type renamed and
various small changes. Adds another axis of configurability to the
existing layer mode madness, and is WIP too.
from gimp_applicator_new() and gimp_gegl_mode_node_set_mode().
Compositing doesn't depend on the layer format any longer, only on the
layer mode. Painting with "use applicator" unchecked is still broken
in some cases and needs more fixing.
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 "gboolean use_cache" to gimp_applicator_new(). Don't use a cache
anywhere but in GimpImageMap because it incrementally fills that cache
via the projection update. In gimp_drawable_merge_filter(), get that
cache and pass it to gimp_gegl_apply_cached_operation() which then
avoids doing the work twice for the already cached results. Win!
- 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
Add "linear" parameter to GimpApplicator. Pass the drawable's "linear"
to the applicator, and to all calls to gimp_gegl_mode_node_set_mode(),
instead of hardcoding FALSE everywhere.
Add GimpOperationMaskComponents, enum GimpComponentMask, and image and
drawable infrastructure to get the right mask, and plug the mask
operation into gimp_gegl_create_apply_buffer_node().
