... which allows temporarily turning the applicator into a NOP,
without destroying cached data.
This commit also improves gimp_applicator_set_{src,dest}_buffer().
In gimp_drawable_merge_filter(), disable the filter applicator's
cache and output-format conversion nodes before processing the
uncached region of the filter, so that the result is written
directly to the drawable's buffer.
We're going to use GimpApplicator's output crop for more than just
split previews. Rename gimp_applicator_set_preview() to
gimp_applicator_set_crop(), and add gimp_applicator_get_crop(),
which returns the output crop rectangle, or NULL if cropping is
disabled.
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.
In GimpApplicator, add gimp_applicator_set_output_format(), which
can be used to explicitly set the format of the result. In
particular, this allows controlling the output cache format, which
can speed up the merging of cached filters.
this commit changes just those which make no difference to
functionality: property and object member defaults that get overridden
anyway, return values of g_return_val_if_fail(), some other stuff.
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.
... layers with alpha channel
add an operation that selectively outputs aux
or source if out/inside the rectangle (x,y,width,height),
independently of the alpha channel and use it
in filters split preview.
mostly copied from gimp:mask-components
When set, it crops the effect to that rectangle, using a cache for
quickly changing the previewed area. When disabling the preview rect,
make sure we don't lose the cached result by processing it into the
output cache through the mode and affect nodes which is cheap-ish.
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!
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.
which means adding a lot of proper API. Input, output and aux can be
pads or buffers. Make sure it uses the minimum possible graph in all
cases and doesn't reconfigure nodes unless needed. Port GimpPaintCore
to the new API.
and use it in GimpPaintCore, instead of calling
gimp_drawable_apply_buffer() which sets up a new graph for each
call. Makes painting speed bearable again.
