Add a new 3D Transform tool, based on GimpToolTransform3DGrid,
added in the previous commit. The tool UI provides a notbook with
three tabs, corresponding to the three GimpToolTransform3DGrid
modes:
Camera - allows setting the primary vanishing point, as well as
the camera's focal length, expressed either directly, or as the
camera's angle of view, relative to the whole image or the
transformed item. By default, the vanishing point is aligned
with the item's center, and the angle of view is fixed relative
to the item; this essentially means that each item is transformed
using a local perspective, independent of its position and size
relative to the image. A global perspective can be achieved by
using a common vanishing point and focal length (or an image-
relative angle of view).
Move - allows moving the item using X, Y, and Z offsets.
Rotate - allows rotating the item using X, Y, and Z Euler angles.
The order of rotation of the different axes can be controlled by
a set of numbered buttons next to the sliders, and the rotation's
pivot can be controlled using a pivot selector.
Add a new GimpToolTransform3DGrid tool widget, subclassed from
GimpToolTransformGrid, which can be used to perform 3D
transformations.
The widget can be in one of three modes:
CAMERA - allows adjusting the primary vanishing point by moving a
handle.
MOVE - allows moving the object through dragging.
ROTATE - allows rotating the object through dragging.
By default, controlling the transformation through dragging applies
to the X and Y axes. Holding Shift (or setting the "constrain-
axis" property) restricts the motion to only one of the axes.
For the MOVE and ROTATE mode, holding Ctrl (or setting the "z-axis"
property) allows controlling the Z axis instead.
For the same modes, holding Alt (or setting the "local-frame"
property), applies the adjustments in the object's local frame of
reference, instead of the display's global frame of reference.
Add a boolean GimpTransformGridTool::dynamic-handle-size property,
which controls whether the handle sizes are adjustment dynamically
according to the grid's size, or remain fixed. This property is
TRUE by default, to maintain the current behavior.
In GimpToolTransformGrid, allow setting "inside-function" and
"outside-function" to a new NONE value, performing no
transformation when dragging the respective area.
GimpPivotSelector is a 3x3 grid of toggle buttons, used for
selecting a natural pivot position (e.g., for a transform) relative
to an item: its center, its corners, and the midpoints of its
edges.
The tool dialog of generic-transform tools (the Unified,
Perspective, and Handle Trasnform tools) shows the current
transformation matrix. Although we might as well show *something*
in the dialog (we can't get rid of it altogether, as it provides
the common tool actions), this information is probably meaningless
for most users, and isn't directly editable anyway.
Reduce the size of the matrix, to make it less prominent, and free
up some space.
Add a boolean 'compress' parameter to
gimp_transform_grid_tool_push_internal_undo(). When TRUE,
successive undo steps added rapidly are compressed into a single
step.
In the various subclasses, compress undo steps for dialog changes,
since we push an undo step for every intermediate change for those
(such as while dragging a spin-scale). In contrast, we only push
tool-widget undo steps upon button release, hence there's no need
to compress them.
In gimp_transform_grid_tool_push_internal_undo(), only flush the
image when undo/redo availability for the tool changes, instead of
for every undo step. This speeds things up when many undo steps
are pushed in succession, which usually happens when using the tool
GUI.
In GimpSizeEntry, the value corresponding to 0%, as per
gimp_size_entry_set_size(), may be non-zero. This works correctly
when using the size entry in percentage mode, but not when using
precentage as part of arithmetic.
Fix this by adding an 'offset' parameter to eevl's unit-resolution
callback, which can be specifies a constant value to add as part
of unit conversion, after scaling the converted value by the
conversion factor. In GimpSizeEntry, use this parameter to offset
percentages by their lower bound.
Which is a linear transform of xyY that is more perceptually
uniform, and so well-suited for eventually adding chromaticity
diagrams to GIMP color tools. ACES documentation uses this color
space instead of xyY for showing chromaticity diagrams. Moving
forward I expect other venues also will start using Yu'v' as
the advantages over xyY chromaticity diagrams are fairly obvious.
Adds a number of modifier keys to the layer dockable's new "Merge Down"
button to access further functions, and adds among them a new action to
merge visible layers using the dialog's last values, akin to those
accompanying the New Layer and Add Layer Mask dialogs.
Modifier keys are bound as follows:
Shift -> Merge layer group
Ctrl -> Merge visible layers
Ctrl + Shift -> Merge visible layers from last used values
The Merge Down button is kept sensitive even when the current layer
can't be merged down to allow access to these functions
As they are both mutually exclusive and serve an almost identical
purpose, the "Merge down" and "Anchor Layer" are given mutually
exclusive visibility in menus, and the anchor button is replaced
with a merge down button in the Layers dockable whenever there is
no active floating selection
Not because they are working better than the ones in autotools, but
rather because it seems they are simply barely implemented! So of
course, the few tests currently there work.
gtk_widget_get_window() may return NULL. I had the case when opening
some menus in bottom of tool options (like the "Save|Restore Tool
Preset" menus). We must check this before doing anything with it.
Previously we were only passing this information on the debug dialog
when debugging warnings and criticals. Now it will also have the
information for crashes, hence recommending people to update their GIMP
instead of reporting bugs on old versions.
… twice.
It should not be freed by the caller since it is annotated as (transfer
none). It gets freed when calling gimp_procedure_config_end_export().
Thanks to Massimo for noticing.
Instead of making the focus on bug reporting, the debug dialog will now
make the focus on updating the application if it is found that one is
not using the last version.
Debug data (backtraces and co.) will still be available and copiable,
but under an expander, and bug report button won't be displayed (i.e.
data will still be available upon request but we don't push anymore
people to submit it directly if they are using old versions of GIMP).
Of course, if you are using the last version (or version check was not
possible), the dialog still stays the same.
The old custom ArchLinux got broken (apparently by some package
signature verification which fails, and obviously we don't want to
bypass these for security reasons).
I took the opportunity to port to Debian testing because this is GIMP's
base distribution for support (basically dependency versions must be in
Debian testing) so it makes sense that our CI is based off it as well.
Note though that I am not against additional CI tests so if someone
absolutely wants to get the Archlinux-based CI back and thinks it gets
us some additional worthy test, feel free to fix whatever was broken
then we may add it back (having both Debian testing and Archlinux CI).
When the "Omit hidden layers and layers with zero opacity" option is
set, this property was only checked on non-group layers. So if we had
non-hidden layers inside hidden layer groups, they ended up exported,
which is not the expected behavior.
See https://gitlab.gnome.org/GNOME/gimp/issues/4425#note_675350
Adds a new PDF export option "Convert text layers to image", which
defaults to FALSE (because text staying text is obviously usually
prefered).
Also loop through text layers to detect missing fonts. In case any are
found, add a warning in the export dialog, below the new option,
advising to enable this option if design matters (if fonts are missing,
PangoCairo seems to select any other random font and embed it into the
PDF instead of the expected one).

In gimp_tag_entry_assign_tags(), don't add/remove tags while iterating
tag_entry->selected_items, because that might change the list. Instead,
make a temporary deep copy of the list and iterate the copy. Spotted
by Massimo.
This member of the GTypeInfo structure is the size of the object
instance (not of the parent instance). Let's fix it for all static type
registrations in this file, which had the same bug as commit
0eb6ff41cf.
Happy new year everyone!
