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.
...in both the core and libgimp.
Images now know what the default mode for new layers is:
- NORMAL for empty images
- NORMAL for images with any non-legacy layer
- NORMAL_LEGAVY for images with only legacy layers
This changes behavior when layers are created from the UI, but *also*
when created by plug-ins (yes there is a compat issue here):
- Most (all?) single-layer file importers now create NORMAL layers
- Screenshot, Webpage etc also create NORMAL layers
Scripts that create images from scratch (logos etc) should not be
affected because they usually have NORMAL_LEGACY hardcoded.
3rd party plug-ins and scripts will also behave old-style unless they
get ported to gimp_image_get_default_new_layer_mode().
... and fix flatten-image along the way. *And* do some cleanup.
Currently, gimp_image_merge_layers() combines the layers on its own,
one by one. This is incompatible with pass-through groups, because
the group's buffer is rendered independently of its backdrop, while
we need to take the backdrop into account when mergeing the group.
Instead, render the subgraph of the parent graph, corresponding to
the set of merged layers, directly into the new layer. Since the
layers we merge are always visible and continuous, all we need is a
minor massage to the parent graph to make it work. This takes care
of pass-through groups intrinsicly.
This commit also changes the behavior of flatten-image: Currently,
the flattened layers are rendered directly on top of the opaque
background, which can make previously-hidden areas (due to layers
using composite modes other than src-over, or legacy layer modes)
visible. This is almost certainly not desirable.
Instead, construct the graph such that the flattened layers are
combined with the background only after being merged with one
another.
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!
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.
instead, simply use rgb values and rely on the subsequent
gegl_buffer_set_color() to do the right thing because the buffer know
their indexed format now.
because it would require really evil hacks to honor these properties
in the gegl projection if they were on the mask, and because they
actually belong to the layer.
Add "gboolean merge_active_group" to gimp_image_merge_visible_layers()
and pass FALSE from the PDB wrapper so plug-in invoked layer merging
always acts on the toplevel container as it did in 2.6. Do the same
when opening an image as layer.
Also, added a "Merge within active group only" toggle to the merge
layers dialog and pass it down to the core, but default to TRUE here
so.
