Add gimp_item_{start,end}_move(), and corresponding
GimpItem::{start,end}_move() virtual functions, which should be
called before/after "moving" the item (i.e., translating, scaling,
resizing, flipping, rotating, or transforming the item). Moves
performed between the outermost pair of start/end calls are treated
atomically.
What exactly does "treated atomically" entail depends on the
subclasses -- GimpItem doesn't provide a default implementation for
these functions, so the current commit doesn't change any behavior.
The next commit, which adds layer-mask support for group layers,
uses the functions to avoid cropping the mask too early while a
child is moving.
GimpItem calls {start,end}_move() in the various "move" functions
(gimp_item_{translate,scale,...}(), before performing the actual
operation. Additionally we call the functions in the
gimp_image_item_list_foo() functions, for each participating item,
so that the items are moved as a unit. We call the functions in
the various gimp_image_remove_foo() functions, since removing an
item may affect the size of its ancestors, and is therefore akin to
moving. We also call the functions in GimpEditSelectionTool, so
that the move tool moves items atomically while dragging.
Add gimp_item_get_merged_color_tag(), which returns the color tag
of the nearest ancestor (including the current item) that has a
color tag other than NONE. Use this function in GimpItemTreeView,
instead of gimp_item_get_color_tag(), to set the cell color of
items, so that item's with a NONE color tag inherit the color of
their parent. Add a boolean "inherited" parameter to
gimp_get_color_tag_color(), which indicates if the color tag is the
item's actual color tag, or an inherited color tag, and modify the
returned color accordingly, so that inherited colors are less
saturated/lighter than non-inherited ones.
Add an "active" property to GimpFilter, which replaces its
"visible" property. The new property assumes the lower-level role
"visible" had -- controlling whether the filter has any effect as
part of its parent filter-stack.
Add a "visible" property to GimpItem, separate from the "active"
property, which assumes the higher-level role "visible" had --
controlling whether the item is considered "visible", as per the
GUI. By default, the item's "visible" property is bound to the
filter's "active" property, so that changes in visibility directly
affect the filter's "activeness"; this binding can be controlled
using the new gimp_item_bind_visible_to_active() function.
This distinction is currently necessary for floating selections.
Floating selection layers must not be active in their parent stack,
regardless of their visibility, in particular, so that their mode
node doesn't hide the entire backdrop when their composite mode
excludes the backdrop (i.e., when it's dst-atop or src-in).
Instead, their visibility should affect the activeness of the
floating-selection filter of the drawable they're attached to.
This is handled by the next commit.
Add property "color-tag" of type enum GimpColorTag to GimpItem so all
layers, channels and paths can be tagged with a color.
For interoperability, use the color list from Krita which is a
superset of Photoshop's colors.
Features a "Color Tag" submenu in the layers, channels and paths
menus, a row of color radio buttons in the properties dialogs,
undo and PDB API.
As a side effect, some common code is now factores out into
items-actions.[ch] and items-commands.[ch] which adds visible, linked
and lock actions for layers and channels.
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.
For selections, it's different from gimp_edit_fill() because it
ignores the selection while filling, just as stroking does. Currently
unused, stay tuned...
also add "GType old_type" to GimpItem::convert() so implementations
can do things depending on the type of the original item.
In gimp_layer_convert(), if the original item is also a layer, and
color management is not off (with a FIXME because this is the wrong
check), pass convert_profile = TRUE to gimp_drawable_convert_type().
There is no color profile conversion anywhere behind this, this is
just an API change commit.
Which returns a boolean indicating if there is content at all, and the
bounds as double x, y, width, height because for most use cases that's
better than x1, y1, x2, y2. Wrap the method with two functions
gimp_item_bounds() which returns integer bounds and
gimp_item_bounds_f() which returns the original double bounds.
when they are added to items, images or globally, from the PDF or an
XCF file. None of the validation functions does anything currently,
they simply return TRUE.
Port selection/path stroking to using the PDB-controllable
paint options that live in GimpPDBContext.
Change gimp_item_stroke()'s "use_default_values" boolean which was
introduced at a time where we had no better way by a GimpPaintOptions
parameter. If a non-NULL paint_options is passed (when called from the
PDB), use it for stroking; if NULL is passed, use the actual paint
tool options from the GUI (when called from the menus or the stroke
dialog). In the PDB wrappers, get the right paint options object from
the PDB context associated with the calling plug-in.
Apply and heavily modify patch from remyDev which adds "lock position"
to GimpItem, similar to "lock content". Lock position disables all
sorts of translation and transform, from the GUI and the PDB.
Cleaned up some aspects of the lock content code as well because a
second instance of similar code always shows what went wrong the first
time.
and implement it in GimpLayer to unset the removed flag on the layer
mask. Remove layer mask special casing from gimp_image_add_layer().
Make sure that all an item's children get their removed flag unset in
gimp_item_unset_removed().
- The image *must* now be passed to g_object_new() when creating items
- Remove the "image" parameter from all item configure() functions
- Set the item's ID in gimp_item_set_image() if it has none yet
There is nothing drawable-specific in there, and having them on
GimpItem enables some simplifications, esp. in upcoming PDB
wrappers. None of these refactorings is in this commit though.
Which replaces all the deparate functions to turn layers, channels,
layer masks and vectors into selections. Use the new virtual function
all over the place instead of calling the functions in
gimpchannel-select.c manually.
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.
Sets the "width" and "height" properties and emits notifications and
"size-changed" if anything has changed. This in only to be used by
functions that actually resize the item, it does not scale/resize
anything.
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.
Took patch from Martin Nordholts and ported it to add a "lock-content"
property, signal and API in the same way as it's done for "visible"
and "linked".
This is just a utility function like gimp_image_get_layer_iter()
in order to avoid including "core/gimplist.h" whenever a file needs
access to the actual GList inside the container.
* 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.

* 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.
svn path=/trunk/; revision=27913
* app/core/gimpitem.c (gimp_item_set_offsets): New function that
sets the offset of the item and also keeps the offset_node in
sync.
* app/core/gimpdrawable.c (gimp_drawable_real_set_tiles): Use the
function instead of setting the offsets directly. Fixes corrupted
display when cropping images with GEGL enabled for the projection.
