Wherever we store arbitrary-format colors in an opaque buffer, use
double for the buffer, instead of char, so that it has a strict-
enough alignment to handle all our used pixel formats.
Color picking on a single layer still works as it used to. On multiple
layer, it will now pick on the composited color, similarly to sample
merged if only selected layers were made visible.
The PDB/libgimp function gimp_image_pick_color() is also updated to work
on multiple drawables too, giving the same ability to plug-ins (the only
call to this function in core plug-ins have been updated).
I am currently unsure of this one. Since GimpCanvasLayerBoundary is a
GimpCanvasRectangle, it now shows the minimum rectangular boundary
containing all selected layers.
Should we instead show all individual layers boundary? I didn't choose
this because it would make the whole canvas much more messy, and also I
figure that layer boundaries are mostly used to get an idea of your
current working space extent, for instance if we were to resize the
canvas. Matter to discuss, I guess.
These actions raise a GimpViewableDialog. For this to work, I made this
widget work with a list of GimpViewable, not a single viewable anymore
(so maybe the widget class name should change?).
When this list contains only a single GimpViewable, it will display
exactly like before, with a viewable preview. With several viewables,
the preview won't show.
This allows to add masks to all selected layers at once, with the same
basic options for all masks, as set in the dialog.
After much thought, tests and discussions with Aryeom, we decided adding
back an active item concept additionally to the selected items ones is a
bad idea as it makes only usage unecessarily complex.
We will just have selected layers. Some kind of operations will work
when more than one item (layers, channels, vectors) are selected while
others will require exacty one item.
In particular, let's replace instances of gimp_image_(s|g)et_active_*()
by corresponding gimp_image_(s|g)et_selected_*(). Also replace single
item in various undo classes by GList of items.
Also "active-*-changed" GimpImage signals are no more, fully replaced by
"selected-*s-changed".
This is still work-in-progress.
When using "show all" by default, gimp_display_flush() can be
called during GimpDisplayShell construction, before the newly-
constructed shell is assigned to the display. Use an ugly hack to
just ignore the flush when this happens.
Add a new GimpToolFocus tool widget, which defines a focus region,
consisting of an inner limit, an outer limit, and a transition
midpoint between them. The widget allows controlling the limits
and the midpoint, and moving, scaling, and rotating the region.
Add a new GimpCanvasLimit canvas item, which draws an area limit
for different shapes. It will be used by the following commits to
implement GimpToolFocus.
In GimpDrawTool, update the tool widget on GIMP_TOOL_ACTION_RESUME,
so that it can respond to changes in the display-shell scale/
offset. We'd previously done that for individual tools/widgets,
but let's just do it in one place.
... when rulers and scrollbars are hidden
In gimp_display_shell_fill(), make sure a size-allocate always
happens for the canvas, even when the rulers and scrollbars are
hidden, so that the pending size_allocate_center_image is handled,
and doesn't block canvas drawing.
* Don't generate our own marshallers if they are available in GLib
already
* Don't set the c_marshaller parameter in `g_signal_new()` if it's a
default marshaller provided by GLib. See commit message of commit
39e4aa3c57 on why this is the case.

In GimpCanvasBufferPreview, take a strong reference on the preview
buffer, fixing a segfault in the foreground-select tool when
switching engines while the grayscale preview is active.
Add a "clip" property to GimpCanvasTransformPreview, specifying the
transform's clipping mode, and clip the preview accordingly.
In GimpTransformGridTool, sync the tool's clipping mode with the
preview's clipping mode.
Add a "Unified interaction" option to the 3D Transform tool, and a
corresponding "unified" property to GimpToolTransform3DGrid. When
active, all three interaction modes of the grid (camera, move, and
rotate) are available simultaneously, regardless of the active
dialog page. In this mode, the inner and outer regions of the item
are used for moving and rotation, respectively, and the vanishing-
point is controlled through through a handle.
In GimpToolTransform3DGrid, fix the test for determining which side
of the plane is facing the viewer, affecting the direction of
rotation when rotating around the local Z axis.
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.
More of the files were wrong, or at least not absolutely identical to
the files generated by the autotools. I am not doing any code change
other than trying to make both build systems produce identical files
(except for slight differences on 2 files not worth the effort) even
though maybe some things can be improved (especially on the include
list). Maybe to be improved later.
Also fixing 2 of the previously autotools-generated files because of
space typos which should have been committed earlier.
Finally it is to be noted that there is no logics to copy the generated
files back to the source directory in the meson rules. I am not sure
anyway this is really worth it and maybe we should just stop tracking
these generated files eventually.
See #3996.
This was a warning raised by the Coverity scan on one of the lines. I
fix also in the same time other arithmetics mixing int and double.
Better be thorough.
The specific warning was on:
> circ = 2.0 * G_PI * (private->width / 2)
where the division was integer, which was probably not intended. Of
course that error (display item only) was likely barely visible anyway,
still…
and remove a gazillion gtk_widget_show() all over the place, some
places need a gtk_widget_hide() now, and I'm pretty sure I broke at
least one thing in all those files...
... which is similar to gimp_display_shell_get_pickable(), however,
it returns the projection, rather than the image, only when
gimp_display_shell_get_infinite_canvas() is TRUE, i.e., when the
shell is in "show all" mode *and* canvas padding is disabled.
Add an option to keep the normal canvas padding in "show all" mode,
instead of extending the checkerboard pattern indefinitely. This
is useful when wanting to show the image content beyond the canvas,
while still keeping the focus on the canvas; further commits will
extend this mode to behave in more view-related cases as if "show
all" wasn't enabled.
Add a new 'View -> Padding Color -> Keep Padding in "Show All"
Mode" toggle, which controls this behavior, with a corresponding
default-value option in the preferences, under "Image Windows ->
Appearance".
In GimpDisplayShell, scale the render cache by the window's scale
factor, and render its content in device pixels, instead of scaled
application pixels. When painting the cache to the screen, unscale
the cairo context by the same factor, so that it's painted in the
native resolution. Note that the various
gimp_display_shell_render_foo() functions still speak in
application pixels, and the scaling happens internally in
gimp_display_shell_render().
Aside from rendering at native resolution on HiDPI, this also fixes
an issue where grid-like display artifacts would appear when the
render cache was not fully validated due to the non-native scaling.
... after commit 2c9a8a567b. Don't
use the same function as a handler for GimpContext::display-changed
and GimpContext::image-changed -- their signatures are different.
In GimpNavigationEditor, make sure to clear the editor's shell when
the last image is closed, even though the corresponding display is
stil alive, so that we don't needlessly extend the lifetime of the
image. This is necessary after the recent GimpImageViewable
changes, since the editor now (indirectly) holds a reference on the
image.
Update the image-projection priority rect to the current display's
viewport when the display becomes active, so that the right region
is rendered first when switching between different displays of the
same image.
Add a show_all parameter to gimp_image_pick_color(), which, when
TRUE, allows picking colors outside the canvas bounds in sample-
merged mode. Forward the display's "show all" mode through this
parameter where applicable (in particular, in the color-picker tool
and the pointer dockable).
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.
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 "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.
GimpDisplay contains only the ID logic and the "gimp" and "config"
pointers, and lives in the core.
GimpDisplayImpl is a subclass and contains all the actual display
stuff. The subclass is only an implementation detail and doesn't
appear in any API.
Remove all hacks which pass displays as gpointer, GObject or
GimpObject through the core, or even lookup its type by name,
just use GimpDisplay.
In GimpCanvasTransformPreview, use a GimpPickable, instead of a
GimpDrawable, as the preview source, so that we can use it with the
image projection, rather than just with drawables.
... which controls whether or not the image is rendered by the
shell. We'll use this to hide the image while showing its
transform preview in the next commits.
Basically this commit makes sure that all return values that are marked
as "Returns:" also have a `(nullable)` annotation if it is mentioned on
the same line that NULL can also be returned.
This will prevent a few problems in GObject-introspection.
Documentation-wise in C, this doesn't matter a lot, but it allows
GObject-Introspection based bindings to use their built-in versions when
they want to render any kind of documentation (for example, docs for
Python plugins can render `%NULL` as `None`).
which means that it's now included normally via gimpbase.h
and not any longer via gimpbasetypes.h which we only did out
of lazyness. A *lot* of files in libgimp* and app/ now need to
Since introducing gimp_display_shell_canvas_tick() we were setting
shell->disp_width and shell->disp_height in the tick callback, which
was too late and caused redundant rendering and scrolling, but was
never noticed.
Now we clear the render cache and its valid region in
gimp_display_shell_canvas_size_allocate() directly and set
shell->disp_width and shell->disp_height immediately, so other places
that listen to the canvas' size-allocate get the right values.
The old size of the canvas gets to the tick callback using a small
struct as user data.
Revert the previous commit 786686a541 and comes up with a better fix.
Let's actually change the image base type and add its colormap as close
as possible without any GUI calls in-between. I also add an explicative
comment so that people are aware of this call proximity requirement to
avoid future problems when the code gets remixed.
It should be better than hacking around with exception in GUI code, and
should (hopefully) avoid other similar bugs.
Fixes the GIMP-CRITICAL:
> gimp_babl_format_get_trc: assertion 'format != NULL' failed".
During an indexed conversion, we are in a weird limbo state between the
time we changed the base-type to GIMP_INDEXED and when we actually set
the new palette. If during this time, we hit a context switch (which
typically happens during GUI code; in this specific cases, the various
progress updates would call gimp_widget_flush_expose() which does
trigger context switch), then gimp_display_shell_update_title_idle()
might be idly called. And when it does, it sees an indexed function with
neither format nor builtin profile.
Must initialize shell->render_buf_width,height before realize(), so
move the code to gimp_display_shell_init(), it doesn't depend on the
shell being realized.
When set to FAST we do nearest neighbor from the next bigger mipmap
level instead of linear or box filtering - this gives a slight and
permanent boost to painting, and all updates, having one that combines
best of both worlds and reblits in high quality after a timeout would
be even more desirable.
Introduce a render cache that keeps the result of scaling, color
management, display filters and shell mask (for tools like fuzzy
select).
Change gimpdisplayshell-render.[ch] to only render to the cache and
manage a cairo region of the cache's valid area. Call cache
invalidation functions form various places. Change the API of all
render functions to be in display coordinates.
Also get rid of gimpdisplayxfer.[ch] because we now have a
canvas-sized cairo surface which is a surface similar to the
destination surface.
Step one: get rid of all those deprecation warnings that make
it hard to see any other warnings:
- add a lot of dummy API to GimpAction, GimpActionGroup, GimpUIManager
etc. which simply forwards to the deprecated GTK functions, they
will all go away again later
- rename GimpAction to GimpActionImpl
- add interface GimpAction that is implemented by all action classes,
creates a common interface and allows to remove some duplicated
logic from GimpToggleAction and GimpRadioAction, and at the same
time adds more features
Connect GimpDisplayShell to GimpImage::mode-changed and update its
cached color transforms. Also get rid of a duplicate conection to
GimpImage::precision-changed.
This is useful to be able to support file formats other than image
formats. In particular I will use this in the next commit to support a
"GIMP extension" format. When GIMP will open such file, it will
install an extension (not open an image on canvas).
This is an internal flag only, i.e. only usable from core GIMP. File
formats which a plug-in can register are still only image file formats.
Set the priority of the image window's UI-manager update idle
slightly higher than the projection idle priority, so that the
image actions are updated during projection rendering.
In GimpTransformGridTool, avoid producing non-finite coordinate
and angle values. In particular, this fixes a crash in
gimp_transform_grid_tool_get_cursor() as a result of a NaN angle
value being converted to a negative integer, hitting an assert.
In gimp_tool_gui_set_response_sensitive(), silently ignore non-
existent response IDs, instead of emitting a CRITICAL, to match the
behavior of GtkDialog and GimpOverlayDialog. This simplifies code
with optional dialog responses.
In the unified-transform, scale, and perspective tools, take the
maximal transform-grid handle size into account when readjusting
the transform, so that the handles themselves are fully within view
under arbitrary rotation, rather than just the corners.
In GimpToolTransformGrid, use the transformed center-point of the
original polygon as the position of the center-point handle, and as
a snapping point for the pivot when "cornersnap" is TRUE, instead
of using the center-point of the transformed polygon. These two
points are different for non-affine transformations.
Furthermore, when "use-pivot-handle" is FALSE, use the center-
point as the reference point when transforming around the pivot,
instead of the pivot itself, which might not be set. In
particular, this fixes transformation around the pivot in the
perspective tool.
Don't explicitly set the center-point as the pivot in the scale
tool, since this commit makes it unnecessary.
gimp_widget_flush_expose() has been removed since commit 3089a20167.
I now reimplemented it by simply checking if event sources are waiting
to be processed.
This was heavily needed as the statusbar was not showing any progress
(at least on highly demanding process, such as saving or loading files),
and therefore we were stuck with a seamingly frozen GUI.
Despite the name, this does not apply to a widget in particular anymore,
but to the whole program events.
`icon_space_width` is set when GtkWidget::style-updated signal is
emitted. In some cases, it was possible that gimp_statusbar_set_text()
is run before this happens, in which case, a division by zero would
crash the software.
I encountered this case in some rare occasions when duplicating an image
with ctrl-d, then as Ctrl was hold, the message "Click in any image to
pick the foreground color" was pushed on the brand new statusbar as it
is created (hence a race condition occurs with the signal handler and
this message). This was therefore not reproducible every time, but easy
enough to reproduce with multiple tests.
In GimpToolCompass, add a read-only "effective-orientation"
property, which returns the actual orientation of the compass; in
particular, if the "orientation" property is set to AUTO,
"effective-orientation" returns HORIZONTAL or VERTICAL, depending
on the current compass direction. In 3-point mode, the property
always returns AUTO.
In GimpToolRectangle, fix the type of the cornder_radius field, so
that non-integer radii are properly displayed.
In GimpRectangleSelectOptions and GimpToolRectangle, increase the
maximal corner radius.
We were doing it all the wrong way, fixing one combo box object at a
time. So this commit basically reverses commits 68a33ab5bd, 6dfca83c2a
and a9a979b2d0 and instead runs the same code in the class code. This
way, all objects based on these base classes will have the fix from
scratch.
These improved various other drop-down lists (I found some of them, and
probably not all) as I fixed all GIMP custom widgets based on
GtkComboBox.
Note that it has to be run after filling the list apparently (I had the
problem especially with GimpIntComboBox if running in the _init() code,
then the list widget showed wrong).
Add mew gimp_tool_widget_{get,set}_visible() functions, which allow
setting the visibility of a tool widget. While the widget is
invisible, it ignores all events.
Add a GimpToolWidget::message signal, which can be emitted by tool
widgets to display a message, instead of using the ::status signal.
Add corresponding gimp_tool_widget_message[_literal]() functions.
Though the layer list will also show updated, it is much easier to look
at the layer name in the status bar whose position never changes.
Anyway it makes sense to just show a temporary status info message
giving the picked layer name, making it all the easier to find the layer
you are looking for.
In gimp_display_empty(), clear the image of all contexts whose
display is the current display, so that, in particular, when
subsequently updating the action groups, which causes certain
actions to be activated, the image that used to be bound to the
display is not found through the user context. This avoids re-
validating the image projection when closing the last image,
postponing image destruction.
Instead of having layer picking only on paint tools with alt-click, make
it available everywhere with alt-middle click. Moving through layers is
also a way to navigate an image, so it actually makes sense to be with
other modifiers (panning, zooming, rotating), while making the feature
more generic (this is definitely useful whatever the selected tool).
...closing this image while the file is being loaded
Ref the image around all calls to file_open_layers() and
gimp_image_add_layers() so it stays around even if the user closes the
display in the meantime.
Set the label to ELLIPSIZE_END and add some packing options, and
switch from using pango attributes to simply prepending the right
number of spaces to leave enough room for the icon. The attributes
were somehow breaking ellipsation.
In all tools, when the current item can't be edited due to its lock
mask, use gimp_tools_blink_lock_box(), added in the previous
commit,to blink the lock box of the corresponding dockable, in
addition to showing an error message in the status bar, to hint at
the source of the error.
In gimp_tool_compass_update_angle(), use fuzzy comparisson when
determining whether to update the angle properties, to avoid
infinite recursion due to floating-point inaccuracies. In
partcicular, on x86, when using the x87 FPU rather than SSE, the
floating-point registers are 80-bit, while the properties are
stored as 64-bit, which can create small discrepancies between the
calculated angles and the stored values.
Seems we were drawing marching ants for hidden tabs ever since the
introduction of SWM, which is both a horrible waste of CPU time, and
also makes all selections visible on all displays on GTK+ 3.x.
Implement GtkWidget::unmap() in GimpDisplayShell and stop the ants
when the shell is unmapped.
It was not doing anything right since space invasion. We now treat the
built-in sRGB profile like any other profile and never bypass
conversions based on some weird toggle.
Instead, introduce a "Use sRGB Profile" toggle which, when enabled,
hides whatever profile away so the image actually uses the built-in
sRGB profile.
This is different from discarding and then re-assigning the same
profile only by being faster and more convenient.
When re-activating an operation tool by clicking on a different
drawable while the tool is active, we re-call the corresponding
procedure to re-activate the tool, which implictly initializes it.
Avoid initializaing it explicitly in addition to that, since this
leads to the creation of a new config object by the filter tool,
while the GUI still refers to the old, now-dead, config object,
causing CRITICALs or segfaults when changing any parameter.
... changing layers and warping layer B
Add a new GimpToolControl::dirty_action field, which specifies the
tool action to perform when the a dirty event matching the tool
control's dirty mask occurs; this field defaults to HALT. Apply
this action to the active tool in tool-manager in response to a
matching dirty event, instead of unconditionally halting the tool.
Likewise, use this action to stop the active tool in response to a
button-press event on a different drawable in the same image.
Set the dirty action of the gradient and warp tools to COMMIT, so
that they get comitted, rather than stopped, in cases such as
switching layers (including switching to/from quick-mask mode),
and, for the warp tool, changing the selection.
When removing the focus widget of a GimpToolWidgetGroup, use the
last child, rather than the first child, as the new focus widget.
This plays nicer with auto-raise, and is probably better anyway.
When a focused widget is added to a group, make it the new focus-
widget of the group, instead of unsetting its focus if another
widget already has focus.
When removing the focused widget from a group, set a different
widget as the group's focus widget (if one exists), instead of
unsetting the focus widget, so that nonempty groups always have a
focus widget.
In gimp_tool_widget_group_button_press(), explicitly call
gimp_tool_widget_group_hover() before forwarding the event to the
group's hover widget, so that the hover widget gets recalculated.
If a widget is added to the group as a result of a button-press
event, this guarantees that it gets considered as a target for the
same event.
... and G_TYPE_INSTANCE_GET_PRIVATE()
g_type_class_add_private() and G_TYPE_INSTANCE_GET_PRIVATE() were
deprecated in GLib 2.58. Instead, use
G_DEFINE_[ABSTRACT_]TYPE_WITH_PRIVATE(), and
G_ADD_PRIVATE[_DYNAMIC](), and the implictly-defined
foo_get_instance_private() functions, all of which are available in
the GLib versions we depend on.
This commit only covers types registered using one of the
G_DEFINE_FOO() macros (i.e., most types), but not types with a
custom registration function, of which we still have a few -- GLib
currently only provides a (non-deprecated) public API for adding a
private struct using the G_DEFINE_FOO() macros.
Note that this commit was 99% auto-generated (because I'm not
*that* crazy :), so if there are any style mismatches... we'll have
to live with them for now.
In GimpCanvasTransformPreview, add the necessary bits to the
preview graph so that, when transforming a layer, the layer's
opacity and mask are correctly applied to the preview. Note that
since we're still not rendering the preview as part of the image
graph, the output is not always accurate, but it should be good
enough in most cases.

https://gitlab.gnome.org/GNOME/gimp/issues/641
All babl formats now have a space equivalent to a color profile,
determining the format's primaries and TRCs. This commit makes GIMP
aware of this.
libgimp:
- enum GimpPrecision: rename GAMMA values to NON_LINEAR and keep GAMMA
as deprecated aliases, add PERCEPTUAL values so we now have LINEAR,
NON_LINEAR and PERCPTUAL for each encoding, matching the babl
encoding variants RGB, R'G'B' and R~G~B~.
- gimp_color_transform_can_gegl_copy() now returns TRUE if both
profiles can return a babl space, increasing the amount of fast babl
color conversions significantly.
- TODO: no solution yet for getting libgimp drawable proxy buffers in
the right format with space.
plug-ins:
- follow the GimpPrecision change.
- TODO: everything else unchanged and partly broken or sub-optimal,
like setting a new image's color profile too late.
app:
- add enum GimpTRCType { LINEAR, NON_LINEAR, PERCEPTUAL } as
replacement for all "linear" booleans.
- change gimp-babl functions to take babl spaces and GimpTRCType
parameters and support all sorts of new perceptual ~ formats.
- a lot of places changed in the early days of goat invasion didn't
take advantage of gimp-babl utility functions and constructed
formats manually. They all needed revisiting and many now use much
simpler code calling gimp-babl API.
- change gimp_babl_format_get_color_profile() to really extract a
newly allocated color profile from the format, and add
gimp_babl_get_builtin_color_profile() which does the same as
gimp_babl_format_get_color_profile() did before. Visited all callers
to decide whether they are looking for the format's actual profile,
or for one of the builtin profiles, simplifying code that only needs
builtin profiles.
- drawables have a new get_space_api(), get_linear() is now get_trc().
- images now have a "layer space" and an API to get it,
gimp_image_get_layer_format() returns formats in that space.
- an image's layer space is created from the image's color profile,
change gimpimage-color-profile to deal with that correctly
- change many babl_format() calls to babl_format_with_space() and take
the space from passed formats or drawables
- add function gimp_layer_fix_format_space() which replaces the
layer's buffer with one that has the image's layer format, but
doesn't change pixel values
- use gimp_layer_fix_format_space() to make sure layers loaded from
XCF and created by plug-ins have the right space when added to the
image, because it's impossible to always assign the right space upon
layer creation
- "assign color profile" and "discard color profile" now require use
of gimp_layer_fix_format_space() too because the profile is now
embedded in all formats via the space. Add
gimp_image_assign_color_profile() which does all that and call it
instead of a simple gimp_image_set_color_profile(), also from the
PDB set-color-profile functions, which are essentially "assign" and
"discard" calls.
- generally, make sure a new image's color profile is set before
adding layers to it, gimp_image_set_color_profile() is more than
before considered know-what-you-are-doing API.
- take special precaution in all places that call
gimp_drawable_convert_type(), we now must pass a new_profile from
all callers that convert layers within the same image (such as
image_convert_type, image_convert_precision), because the layer's
new space can't be determined from the image's layer format during
the call.
- change all "linear" properties to "trc", in all config objects like
for levels and curves, in the histogram, in the widgets. This results
in some GUI that now has three choices instead of two.
TODO: we might want to reduce that back to two later.
- keep "linear" boolean properties around as compat if needed for file
pasring, but always convert the parsed parsed boolean to
GimpTRCType.
- TODO: the image's "enable color management" switch is currently
broken, will fix that in another commit.
In GimpToolCompass (and, as a consequence, in the measure tool),
update the measured angle when the shell is scaled, rotated, or
flipped, so that we always satisfy the compass's constrains, and
render correctly.
When using a GimpToolCompass in 3-point mode, add a small gap after
the angle arc to the line corresponding to the "second" non-origin
point, so that it's visually distinguishable from the line
corresponding to the "first" point. This has significance for the
measure tool, since it determines the direction of the rotation
when straightening the image (the first point is rotated toward the
second point.)
Add an "orientation" property to GimpToolCompass, which can be one
of "auto", "horizontal", or "vertical", and which controls the
orientation of the line against which the angle is measured, when
not in 3-point mode (previously, the line would always be
horizontal.) When "orientation" is "auto", the orientation is
automatically set to either horizontal or vertical, such that the
measured angle is <= 45 deg.
Keep the line horizontal, or vertical, in display-space, rather
than in image-space, so that the compass works correctly even when
the canvas is rotated and/or flipped.
Fix the compass's behavior when the image's horizontal and vertical
resolutions are different, both with and without dot-for-dot.
Add "pixel-angle" and "unit-angle" read-only properties, which
return the measured angle either with or without taking the image's
resolution into account, respectively. These properties will be
used by the measure tool in the next commit, instead of having it
implement its own angle calculation.
Fix gimp_constrain_line() and friends to properly constrain line
angles when the image's horizontal and vertical resolutions are
different, and dot-for-dot is disabled.
