When the image's alpha channel is invisible, paint regions outside
the image contents as black, instead of using a checkboard pattern.
This is especially notable when viewing the image in "show all"
mode.
... to avoid unnecessarily updating their previews while dragging,
and, in particular, to avoid updating the image's GimpImageViewable
size in show-all mode.
In GimpNavigation{Editor,View}, show the full image contents when
the corresponding display is in "show all" mode. Additionally,
when the display's "show canvas boundary" is active, show the
canvas boundary in the navigation view as well.
Add a new GimpImageViewable class, which acts as a proxy viewable
for an image. Unlike the image itself, whose preview is always
restricted to the size of the canvas, a GimpImageViewable provides
a show-all property, which controls whether the preview includes
the full image contents. We're going to use GimpImageViewable as
the source viewable for GimpNavigationView.
Add a "show canvas boundary" display option, and a corresponding
"View" menu item and default-apperance preferences option. When
enabled (the default), the canvas boundary is shown as an orange/
black dashed line in "show all" mode.
In "show all" mode, the image is thought to be "infinite"; this
commit improves the overall scrolling/zooming behavior in this mode
according to this assumption. In cases where a specific image size
is needed (e.g., for the scrollbar bounds, fit-image-in-window,
etc.), the image's full bounding box is used; however, in cases
where a center point is needed (e.g., for the zoomed-out scrollbar
bounds, center-image-in-window), the canvas center, rather than the
bounding-box center, is still used.
... which specifies whether to clip the viewport to the canvas
(previously, it would always be clipped). Use the appropriate
value in all callers, depending on the shell's "show all" mode. In
particular, this commit avoids clipping the image projection's
priority rect to the canvas in "show all" mode.
Add a "show all" mode to GimpDisplayShell, controlled through a
corresponding "View -> Show All" menu item. When enabled, the
entire image content is displayed, instead of cropping the image
to the canvas size. More generally, the display behaves as if the
canvas were infinite. The following commits improve the overall
behavior in this mode.
Add a prefernces option to control the default "show all" state.
In GimpImage, make sure the image's pickable interface keeps
behaving as before (i.e., restricted to the canvas size), even when
the image is in "show all" mode. In contrast, the image's
projection, when used as a pickable, *is* affected by "show all".
... which invalidates the entire image. This replaces all calls to
gimp_image_invalidate() with the full canvas size, since the image
content can now be larger than the canvas.
Add a "show all" mode to GimpImage, which, when active, causes the
image projection's bounding box to be adjusted dynamically to the
combined bounding box of all layers and the canvas. This mode is
controlled through the new gimp_image_{inc,dec}_show_all()
functions, which should be called by the display; a corresponding
display toggle will be added in the following commits.
Note that from the user's perspective, "show all" is a display
mode, rather than an image mode. The GimpImage "show all" mode is
therefore merely an implementation detail, and shouldn't have any
effect on displays that don't use "show all" mode, or the PDB.
The ability to use the image with or without taking its "show all"
mode into account will be facilitated by the next commits.
In GimpProjection, avoid erroneously invalidating the projectable's
preview when flushing the projection and there's nothing to be
flushed, if the chunk renderer is still running, and hence the
projection is not fully rendered yet.
In gimp_gegl_buffer_set_extent(), clear the full now-out-of-bounds
region of the buffer, instead of only full out-of-bounds tiles;
however, we still make sure to clear full tiles, instead of partial
tiles, as much as possible. This prevents (parts of) the old
content of the buffer from showing when it's enlarged again. This
is especially relevant for the image projection, once we add
support for a dynamically-expanding canvas in the following
commits, since the projection of a reexpanded buffer can be
temporarily rendered to the display before it's fully
reconstructed, exposing parts of the old content.
Fixes the error:
> Critical error: gimp_line_art_thaw: assertion 'line_art->priv->frozen'
This may happen in cases when we didn't actually freeze the line art at
pointer click, because we were in an invalid case (for instance,
clicking out of selection), hence we must not thaw the line art either
at button release.
(cherry picked from commit 6391b2bcff)
In GimpProjection, when the projectable's size changes, while its
offset remains the same, simply update the projection buffer's
extent, instead of allocating a new buffer and copying the contents
over.
(cherry picked from commit 1577174739)
... which sets the extent of a buffer with an assigned
GimpTileHandlerValidate, clipping the dirty region to the new
extent.
(cherry picked from commit b4ee9ff055)
.... as a drop-in replacement for gegl_buffer_set_extent(), which,
in addition to setting the buffer's extent, clears any now-out-of-
bounds tiles, to free memory.
(cherry picked from commit 90610ac87e)
Something during the port to gimp-drawable-edit (commit
233ac80de1) broke add-bevel.scm when
the thickness is high enough for the selection to become empty.
Add an explicit check for a selection while constructing the bump-
map layer.
(cherry picked from commit 21649c5eaa)
Change the tooltips of the "Image/Layer -> Transform -> Arbitrary
Rotation..." to make the two actions distinguishable in the action
search dialog, similarly to the other image/layer transform
actions.
