In gimp_layer_start_move(), keep the set of ancestors for which for
which we suspended mask cropping, so that we can resume mask
cropping for the same groups in gimp_layer_end_move(). This is
necessary, since gimp_image_remove_layer() calls gimp_item
start_move() before removing the layer from the layer tree, and
gimp_item_end_move() after removing the layer from the layer tree,
at which point the layer has no ancestors.
gimp_layer_get_effective_mode() returns the actual layer mode,
blend space, comosite space, and composite mode used for the
layer's mode node, allowing them to be different from the values of
the corresponding layer properties. The aim is to allow us to
replace expensive layer configurations with cheaper but equivalent
ones transparently. This is used in the next commit to replace
pass-through groups with normal groups under certain conditions.
The effective values are computed by the new
GimpLayer::get_effective_mode() virtual function. The default
implementation provided by GimpLayer returns the corresponding
layer properties as-is (replaceing AUTO with concrete values).
Subclasses can override this function, providing more
sophisticated logic.
... which return the layer's blend/composite space/mode. However,
unlike the non-"_real" versions, these functions never return AUTO
-- instead, they return the actual space/mode that AUTO maps to for
the current layer mode.
When changing a layer's blend/composite space/mode, avoid
updating the drawable if the real space/mode didn't change (i.e.,
if changing from AUTO to the concrete value, or vice versa.)
The GimpLayer implementation of the GimpItem transform functions,
and the GimpDrawable convert_type() function, apply their operation
to both the layer and its mask. The subclasses of GimpLayer --
GimpGroupLayer and GimpTextLayer -- override some of these
functions, providing their own logic for the layer part, and
duplicating the mask part.
Avoid this duplication by adding a set of virtual transform and
type-conversion functions to GimpLayer. Have the GimpLayer
implementaion of the corresponding GimpItem and GimpDrawable
functions use these functions to apply the operation to the layer,
while taking care of the mask themselves. Have GimpLayer's
subclasses override the new virtual functions, instead of the
GimpItem and GimpDrawable ones.
Note that the existing implementation of convert_type() in
GimpTextLayer neglected to convert the mask, hence text layer masks
retained their old format after conversion. This issue is fixed as
a side effect of this commit.
A boolean flag, specifying whether the backdrop is clipped to the
layer. That's the case when the layer's composite mode is dst-atop
or src-in.
This is a read-only property, derived from the other attributes of
the layer. We compute its value through a virtual function, so that
GimpGroupLayer will eventually be able to specialize it for pass-
through groups.
The next commit uses this property to actually do something useful.
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.
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 a GimpFillType argument to GimpItem::resize() and fill type
widgets to the canvas and layer resize dialogs. Fill the new parts of
the drawable according to fill type in gimp_drawable_resize(). Make
sure places that need the old behavior get GIMP_FILL_TRANSPARENT
passed by hardcoding it in the GimpItem::resize() implemetations of
channel, mask, selection etc.
They are unreliable because every type checking cast discards them,
they are useless anyway, visual clutter, added inconsistently, and
generally suck. Wanted to do this a long time ago, it was a bad idea
in the first place.
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.
and use it to draw the layer boundary. Remove a lot of stuff
that was there only to draw the boundary before:
- remvoe all layer boundary stuff from the selection code
- remove gimp_display_shell_draw_layer()
- remove enum values GIMP_SELECTION_LAYER_ON,OFF from core-enums.h
- remove all lines calling gimp_image_selection_control() with
the removed enum values
- remove gimp_layer_boundary()
this is pretty pointless from an abstraction point of view, but using
these functions will make the code a lot more readable by getting rid
of tons of ugly casts to and from GimpViewable whenever getting an
item's parent.
Add gimp_item_can_lock_content() and gimp_layer_can_lock_alpha() which
return TRUE unless the item is a grop (has children), because group
items will be considered to have lock_content always TRUE and
lock_alpha always FALSE.
* app/core/gimpitem.[ch]: add virtual function ::get_container() plus
pubic API wrapper which returns the children of the item's parent
viewable, or the right toplevel container of its image.
Add utility function get_index() which returns the item's index
within its container.
* app/core/gimpchannel.c
* app/vectors/gimpvectors.c: implement get_container() and return
the right image container.
* app/core/gimplayer.[ch]: same here, and remove previously added
public get_container() API.
* app/core/gimplayermask.c
* app/core/gimpselection.c: implement get_container() for these GimpChannel
subclasses and return NULL.
The new function returns a layer's container, which is either its
parent viewable's children, or image->layers. Scheduled for being
moved to a virtual function on GimpItem.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

2008-11-17 Michael Natterer <mitch@gimp.org>
* app/core/gimplayer.[ch]: add boolean property
"floating-selection" which indicates if the layer is a floating
selection. Add new API gimp_layer_set_floating_sel_drawable()
which sets layer->fs.drawable and emits notify on the property.
Did some minor cleanup in the existing property code.
* app/core/gimpfloatingselundo.c: use the new function instead of
setting layer->fs.drawable manually.
* app/core/gimplayer-floating-sel.c: same here. Remove some
includes and local variables that are obsolete.

Bye bye floating_sel_rigor() and floating_sel_relax():
* app/core/gimpdrawable.[ch] (gimp_drawable_init_src_region):
implement compositing the floating selection on the fly. Add
return parameter "TileManager **temp_tiles" which returns the temp
buffer used for compositing; the caller has to unref the tiles.
* app/core/gimpchannel-project.c
* app/core/gimplayer-project.c: unref the temp_tiles.
* app/core/gimplayer.[ch]: remove members fs.backing_store and
fs.initial.
* app/core/gimplayer-floating-sel.[ch]: remove functions rigor(),
relax(), store() and restore(), they are not needed any longer.
Some minor cleanup, more to come.
* app/core/gimpprojection-construct.c: don't composite the
floating selection before projecting because that happens on the
fly now.
* app/core/core-enums.[ch]
* app/core/gimpfloatingselundo.c
* app/core/gimpimage-undo-push.[ch]: remove the rigor and relax
undos.
* app/core/gimpdrawable.c
* app/core/gimpimage-convert.c
* app/core/gimpimage-duplicate.c
* app/core/gimpimage.c
* app/core/gimplayer.c
* app/xcf/xcf-save.c: remove all calls to rigor and relax and all
implementations of virtual functions that were just there to
rigor/releax around chaining up.
* tools/pdbgen/pdb/floating_sel.pdb: remove all code from the
rigor and relax wrappers and deprecate the API.
* app/pdb/floating-sel-cmds.c
* libgimp/gimpfloatingsel_pdb.[ch]: regenerated.
* plug-ins/file-xjt/xjt.c: don't call rigor and relax.
svn path=/trunk/; revision=27579
* app/core/gimpitem.[ch]: Moved the shift_node from GimpLayer to
GimpItem, and call it offset_node. Also added
gimp_item_get_offset_node() meant to be used in the same way as
gimp_item_offsets().
(gimp_item_real_translate): Keep the offset_node up to date.
* app/core/gimplayer.[ch]: Don't manage the offset_node, get it
from GimpItem instead.
svn path=/trunk/; revision=27527
2008-11-02 Michael Natterer <mitch@gimp.org>
* app/core/gimplayer.[ch]: remove the mask_node and simply set
both opacity and the layer mask's source node on the opacity_node.
Needs latest SVN GEGL.
svn path=/trunk/; revision=27522
2008-10-14 Michael Natterer <mitch@gimp.org>
* app/core/gimpdrawable.[ch]: add a default implementation of
GimpDrawable::get_node() which contains a layer mode node.
Implement GimpItem::visibility_changed() and turn the node into a
nop when the drawable is invisible. Added public function
gimp_drawable_get_mode_node() so subclasses can plug stuff
into its "aux" pad.
* app/core/gimplayer.[ch]
* app/core/gimpchannel.[ch]: changed accordingly (remove
duplicated member and code that is now in GimpDrawable).
svn path=/trunk/; revision=27277
2008-10-10 Michael Natterer <mitch@gimp.org>
* app/core/gimpdrawable.[ch]: add virtual function
GimpDrawable::get_node() which returns a node to be plugged into
the projection.
* app/core/gimplayer.[ch]: remove public get_node() api and
implement the virtual function instead.
* app/core/gimpimage.c: changed accordingly.

Address Bug 554983 – Layers Projection using GEGL
* app/gegl/gimp-gegl-utils.[ch]: add (imcomplete) function
gimp_layer_mode_to_gegl_operation() from bug #554983.
* app/core/gimpdrawable.[ch]: add gimp_drawable_get_source_node()
which returns a GimpOperationTileSource for the drawable's
tiles.
(gimp_drawable_real_set_tiles)
(gimp_drawable_configure): set the node's "tiles" property.
* app/core/gimplayer.[ch]: add gimp_layer_get_node() which returns
a GeglNode with proxy "input" and "output" pads to be plugged
into the projection graph. The node has children for opacity,
mask, layer mode and layer offset.
(gimp_layer_translate)
(gimp_layer_add_mask)
(gimp_layer_apply_mask)
(gimp_layer_set_opacity)
(gimp_layer_set_mode): reconfigure the respective nodes.
* app/core/gimpimage.[ch]: keep a "graph" node around and destroy
it in finalize(). Not even a stub, just a silly GEGL dependency.

2008-09-15 Michael Natterer <mitch@gimp.org>
* app/core/gimplayer.[ch] (gimp_layer_add_mask): add GError
parameter and replace g_message() by g_set_error().
* app/core/gimplayermaskundo.c
* app/xcf/xcf-load.c
* app/actions/layers-commands.c: pass NULL errors since these
places know what they are doing. Ha ha...
* tools/pdbgen/pdb/layer.pdb
* tools/pdbgen/pdb/image.pdb: pass the error so we get more real
error messages for failed PDB calls.

Allow to initialize a new layer mask with any of the image's
channels. Fixes bug #310207.
* libgimpbase/gimpbaseenums.h (enum GimpAddMaskType): added
value GIMP_ADD_CHANNEL_MASK.
* libgimpbase/gimpbaseenums.c
* tools/pdbgen/enums.pl: regenerated.
* app/core/gimplayer.[ch] (gimp_layer_create_mask): added
GimpChannel* parameter. Hacked the GIMP_ADD_SELECTION_MASK code a
bit so it can handle GIMP_ADD_CHANNEL_MASK too. Cleaned up the
function a bit.
* app/dialogs/layer-add-mask-dialog.[ch]: added a menu of the
image's channels.
* app/actions/layers-commands.c (layers_add_mask_response): pass
the channel selected in the menu to gimp_layer_create_mask().
* tools/pdbgen/pdb/layer.pdb (layer_create_mask): use the image's
active channel when GIMP_ADD_CHANNEL_MASK is passed. Fail if there
is no active channel.
* app/pdb/layer_cmds.c: regenerated.
2005-04-09 Michael Natterer <mitch@gimp.org>
Implement dragging and dropping in any GdkPixbuf supported
format. Fixes bug #172794 and bug #172795.
* app/core/gimplayer.[ch] (gimp_layer_new_from_region): new
function which contains all stuff that was in
gimp_layer_new_from_tiles().
(gimp_layer_new_from_tiles): use above function.
(gimp_layer_new_from_pixbuf): new function.
* app/widgets/Makefile.am
* app/widgets/gimppixbuf.[ch]: new files containing GdkPixbuf
utility functions for clipboard and DnD.
* app/widgets/gimpselectiondata.[ch]: removed
gimp_selection_data_set,get_pixbuf(), GTK+ provides the same API.
Also removed GdkAtom parameters all over the place because it's
always the same as selection_data->target.
* app/widgets/gimpclipboard.c: use the new pixbuf utility
functions and gtk_selection_data_set,get_pixbuf().
* app/widgets/widgets-enums.h
* app/widgets/gimpdnd.[ch]: removed never-implemented
GIMP_DND_TYPE_PNG and added a generic GIMP_DND_TYPE_PIXBUF
instead. Added API to drag and drop GdkPixbufs which transparently
converts from/to and GdkPixbuf-supported image format. Removed
passing around of GdkAtoms, since they were always the same
as selection_data->target.
* app/widgets/gimpdnd-xds.[ch]: follow GdkAtom parameter removal.
* app/widgets/gimpcontainertreeview.[ch]: added virtual function
GimpContainerTreeView::drop_pixbuf().
* app/widgets/gimpcontainertreeview-dnd.c: dispatch drop_pixbuf().
* app/widgets/gimplayertreeview.c: implement drop_pixbuf().
* app/widgets/gimpdrawabletreeview.c: allow to drag all drawables
as pixbufs.
* app/display/gimpdisplayshell-dnd.c: allow dropping of pixbufs.
2003-09-04 Michael Natterer <mitch@gimp.org>
* app/core/gimpdrawable.[ch]: added new pure virtual function
GimpDrawable::invalidate_boundary().
* app/core/gimplayer.[ch]: implement it and removed public
function gimp_layer_invalidate_boundary().
* app/core/gimpchannel.[ch]: implement it.
* app/core/gimpselection.[ch]: implement it and removed public
function gimp_selection_invalidate().
* app/core/gimpimage-mask.c (gimp_image_mask_invalidate)
* app/core/gimpimage-undo-push.c
* app/core/gimpimage.c
* app/core/gimplayer-floating-sel.c
* app/text/gimptextlayer.c: changed accordingly.
* app/core/gimpchannel.[ch]: made gimp_channel_push_undo() a
public function and made it call
gimp_drawable_invalidate_boundary(). Added undo_desc strings for
all undo pushing functions to GimpChannelClass.
* app/core/gimpselection.[ch]: removed gimp_selection_push_undo()
since after the change above it was identical to
gimp_channel_push_undo(). Don't push any undo here since
upchaining does the right thing now. Override GimpChannelClass'
undo_desc strings to say "Selection".
* app/core/gimpimage-mask.c (gimp_image_mask_push_undo): changed
accordingly.
2003-08-27 Michael Natterer <mitch@gimp.org>
Enabled type-preserving DND of all kinds of items between
different images. Fixes bug #119983.
* app/core/gimpitem.[ch]: added new virtual function
GimpItem::convert() which duplicates an item for another image.
* app/core/gimplayer.[ch]: removed gimp_layer_new_from_drawable()
and made it a GimpItem::convert() implementation.
* app/vectors/gimpvectors.[ch]: removed gimp_vectors_convert() and
made it a GimpItem::convert() implementation.
* app/widgets/gimpitemtreeview.[ch]: removed GimpConvertItemFunc
typedef and function pointer in GimpItemTreeViewClass since
we can simply call gimp_item_convert() now.
* app/widgets/gimplayertreeview.c
* app/widgets/gimpvectorstreeview.c
* app/display/gimpdisplayshell-dnd.c
* tools/pdbgen/pdb/layer.pdb: changed accordingly.
* app/pdb/layer_cmds.c: regenerated.
