In paint options as well in layer list.
I also updated an opacity spin scale in GimpBrushSelect core widget, but
this one doesn't look like it is used anywhere anymore.

... tools' brush options.
After discussions, it turned out that many people disliked that the spin
scale for brush size (and some other options) get you fractional values.
How often do you actually need to get a 4.32 pixel-size brush? And even
how meaningful is it? On the other hand, you usually want a 4 or a 5
pixel size brush and it's nearly impossible to get (exactly) by dragging
the scale widget.
It is so annoying that some even resort to edit the value with keyboard!
So I am adding an optional "constrain" feature to GimpSpinScale. It will
still be possible to get fractional values when constraining is on, for
instance with keyboard edit (the arrow incrementation also will keep any
fractional part). So the interaction for such scales is simply reversed
so that you get integers easily, and fractional parts with a bit more
effort.
It is not turned on by default (some feature actually need precision and
we don't want to break the sliders for these) and for the time being, I
only applied it to all the brush settings in paint tools. Now that it
exist, we may want to apply this to more scales in various parts of
GIMP.
In gimp:gradient, when using adaptive supersampling, render the
gradient tile-by-tile, using an iterator, instead of row-by-row.
This significantly improves performance, while also avoiding the
assumption that gimp_adaptive_supersample_area() works row-by-row.
Additionally, when not using supersampling, use a single GRand
instance, since the separation to distinct seed and per-tile
instances, which was a threading optimization (commit
7f39e41254), is no longer needed.
When a fill zone was a bit too segmented, you'd want to just stroke
across it. But it was leaving some pieces uncolored, even though the
pointer dragged through it! The exact motion mode allows more events.
Note: I don't set it in the similar color filling (where it could have
been useful too) mostly because it is harder to remove events then (even
if a point was already filled, it could still serve as a seed for more
filling if threshold > 0), thus implied too much processing. Anyway in
all my tests, it was more a problem for line art filling anyway.
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).
The main window height was always bigger than my screen height on
startup, overriding my previous session's window size.
I could retrace the memorized size being changed when adding the display
shell with gimp_image_window_add_shell() in gimp_display_new(), just
before showing the window. Unfortunately this happens after we applied
the session position/size (in gimp_image_window_session_update() at end
of image window construction). I'm not sure why adding the shell
increases the size of the window, especially since the window can be
manually sized at the expected dimension without any graphical glitch.
Maybe we could investigate this, but simply forcing any session managed
window to behave as expected upon showing is not a bad move anyway and
in this specific case, it works fine.
When clearing a channel, do nothing if the channel is already
empty; otherwise, align the cleared rectangle to the channel
buffer's tile grid, so that all affected tiles are dropped, rather
than zeroed. Furthermore, only update the affected region of the
channel.
In commit c71b4916af, I forgot to disconnect signals on the bucket fill
options at finalization, leading the software to crash on an
non-existing tool.
After discussion with Sébastien Fourey and David Tschumperlé, it was
decided that a better fix for the edge case raised in #2785 was to add a
keypoint anyway, even if the point and none of its neigbours have a
positive smoothed curvature, yet they have a positive raw curvature. In
such case, we use the local maximum raw curvature instead of the local
maximum smoothed curvature.
Additionally to sample merge and active layer, now we can only use the
layer above or below the active layer as line art source.
The line art fill is meant to work on drawing lines. Though sample merge
still is ok in many cases, the more you fill with colors, the more the
line art computation becomes unecessarily complex. Also when you use a
lot of layers with some of them already filled with colors, it makes it
impossible to colorize some line art zones with the tool. Moreover you
just don't want to have to hide every layers out there to colorize one
layer (especially background layers and such as you may want to see the
result with your background).
Thus we want to be able to set the source as a unique layer, while it
not being necessarily the active one (because you want lines and colors
on different layers). In this case, I am assuming that the color and the
line layers are next to each other (most common organization).
In gimp_projection_finish_draw(), clear the chunk iterator's
priority rect before finishing rendering, since it's not needed at
this point, and this is slightly more efficient.
In GimpFilterTool, when the filter uses an on-canvas controller,
provide a toggle in the tool's filter-options dialog allowing to
toggle the controller's visibility. This allows getting the
controller out of the way when unneeded.
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.
In GimpDrawTool, do nothing in the tool-widget signal handlers if
the draw-tool isn't active, to avoid CRITICALs due to a NULL
display. This can happen if a widget is set before the tool is
started.
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.
Several en_GB to en_US.
Also "Show a preview of the transform_grided image". "grided" should be
"gridded", but I also have a problem with the underscore. Should it be
"transform-gridded"? Even so, does it really make sense?
I chose to just read "Show a preview of the transformed image", which I
think is simpler and the most understandable (we don't need to leak the
implementation with a transform grid into the human read text IMO). If
anyone think that was not the right choice, feel free to propose
otherwise.
Thanks to Bruce Cowan for noticing these.
In gimp_projection_chunk_render_start(), when the current
projection rendering is complete, but not finalized yet, and no new
rendering is started (since the current update region is empty),
make sure to invalidate the projectable's preview, since it
normally happens when rendering is finalized, which doesn't happen
in this case.
In the gradient tool, halt the gradient editor before committing
the filter, so that its image-flush idle source is removed before
applying the operation, to avoid flushing the image, and hence
restarting its projection rendering, during application.
In gimp_tile_handler_validate_buffer_copy(), temporarily remove the
source buffer's validate handler, is exists, so that the subsequent
gegl_buffer_copy() can use fast tile copying, using the TILE_COPY
command. GEGL currently only uses TILE_COPY when the source buffer
doesn't have any user-provided tile handlers.
In gimp_gegl_apply_cached_operation(), replace the use of
GeglProcessor with GimpChunkIterator, so that we use the same
chunking logic as for rendering projections. This has the
advantage of better chunk alignment to the tile grid and dynamic
chunk sizing, which improve performance.
Use chunking even when there's no progress indication, since it
generally results in better cache locality.
Factor out the region-chunking logic of GimpProjection into a new
GimpChunkIterator type, providing a generic mechanism for iterating
over a cairo region in discrete chunks. The iterator doesn't
perform any processing itself, but rather dispenses rectangular
chunks, which the user then processes.
Iteration is broken into intervals, the duration of which is
configurable. Each iteration begins with a call to
gimp_chunk_iterator_next(), after which
gimp_chunk_iterator_get_rect() should be called in succession to
fetch a rectangle to process, until it returns FALSE, which marks
the end of the iteration. Updates to the UI should take place in
the interval between iterations, but not during an iteration. The
iterator dynamically adjusts the chunk size according to processing
speed, in order to match the target iteration interval.
The iterator can be given a priority rectangle, which is processed
before the rest of the region. It can also be given a
representative tile rectangle, defining a regular tile grid;
dispensed chunks are aligned to the tile grid as much as possible.
This is sometimes asked, and myself also need to find it from time to
time. I may as well put the link inside the code comments, where it is
just easy to find!
Request pixbufs in double size and cache the created surface instead
of the pixbuf. This affects rendering icons and image thumbnails.
All other rendering (which is most previews) is not ported yet, but
just lacks HiDPI quality, there are no actual bugs.
In GimpTool, track the last-seen pointer coordinates, modifier
state, and event time, during button_press() and motion() events
and use those to synthesize a button_release() event when
comitting/halting the tool, if the tool is still active, and a
matching button_release() event has not been received.
The paint tools (as well as other tools) require each
button_press() event to be matched by a button_release() event in
order to properly finish their operation, but one isn't organically
generated when switching tools due to a device change.
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.
