It's still the same visually but it will be useful for 2 reasons: first,
it makes nicer code to show/hide only this one box instead of 3 frames;
second it will be used for the release note demo feature so that we can
blink the full line art settings box.
… on the line art source.
Also now the default tooltip itself will be more appropriate rather than
reusing the "fill-transparent" property blurb (maybe I should have made
this its own property in fact).
This is the same thing as setting the max gap length to 0, except that
it would mean constantly having to play with the gap length and possibly
losing settings you carefully tweaked. Instead with this additional
settings, we hide the gap length settings when automatic closure is
disabled.
Also it makes kind of a nice parallel with the "Manual closure" settings
which can also be enabled/disabled similarly.
Since we can't select a source, the source tools would fail stroking
with an error. It was usable when stroking a path or selection as we
can have the source tool started while running these. Since only one
tool can be started at once, this is not possible when running bucket
fill tool (it would require some logics change on tools).
This change has 2 parts: add an "insensitive" column to
GimpContainerComboBox (allowing to mark some cells as insensitive), then
use this new attribute in the GimpBucketFillOptions to show all source
tools as insensitive.
There are clearly 3 types of settings:
1. How the line art is detected.
2. How do we additionally close line art.
3. How to handle fill borders.
Additionally I am rewording some options:
- "Allow closing lines in selected layer" -> "Manual closure in fill
layer"
- Adding the "Maximum gap length" into an "Automatic closure" frame to
hopefully make a parallel with the "manual" closure settings.
- "Allow completely transparent regions to be filled" -> "Detect opacity
rather than grayscale" (only within the context of the line art bucket
fill) because the main idea of this option is really here that we
detect lines as being opaque pixels, rather than detecting lines are
being dark pixels.
Finally don't hide the manual closure frame when in a configuration
where it won't be taken into account. Only make it insensitive. Having
options disappear is not so nice. Usually you want to gray them out to
have people realize they are simply not always usable.
Currently the option is quite simple. What should happen to make it more
usable:
* Right now, it uses the last stroke options (e.g. as used in a
previously run "Stroke Selection" or "Stroke Path"). We should have
some dedicated GUI in the bucket fill options.
* The bucket fill options GUI should really be redesigned. The more we
add options, the less understandable it is.
* There is a question whether we want to just use whatever brush size is
being set or if we want to have it vary and follow the line art width
(since we have proper distance map, we could use this to tweak the
stroke per-coords).
As usual, this feature was suggested by Aryeom who was still very
saddened that despite all the fancy features in this tool, it is not
able to produce nice rendering. So she proposed that the tool could
stroke the fill region borders.
… gimp_prop_widget_set_factor() to libgimpwidgets.
Now that GimpSpinScale is in libgimpwidgets, it's time to move the
associated prop too, to make it a prop widget with such a widget easily
creatable by plug-ins.
While doing so, I update both these functions logic, binding properties
together with the g_object_bind_property*() APIs (as we do already in
some other recent prop functions) rather than connecting to signals
ourselves. It makes for much simpler code.
The line art algorithm is useful but not always accurate enough and
sometimes it can even be counter-productive to fast painters.
A technique of advanced painters which Aryeom uses and teaches when she
wants to close an area without actually closing the line art (i.e. the
non-closed line is a stylistic choice) is to close with a brush the area
on the color layer. It has also a great advantage over the line art
"smart" closing algorithm: you control the brush style and the exact
shape of the closure (therefore something you'd usually have to redo
with a closure made by an algorithm as you would likely not find it
pretty enough).
This new feature takes this technique into account. Basically rather
than relying on the closure algorithm, you would close yourself and the
tool is able to recognize closure pixels by the color proximity with the
fill color.
Final point is that this additional step is made after line art
computation i.e. in particular the target drawable is not added to the
sources for line art logics. This allows to stay fast otherwise the line
art would have to recompute itself after each fill.
This also shows why the previous commit of moving the line art object
was necessary, because a painter would likely want to move regularly
from bucket fill to a brush tool to create area closures and we want to
avoid recomputation every time.
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 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
This was actually more of a feathering feature I added earlier, and we
already have a function for that: gimp_gegl_apply_feather(). This is
using a gaussian blur, just as what I was doing anyway. This commit also
adds the "Feather Radius" scale, similar to other tools with the
"Feather Edges". So that makes it consistent (and more useful as you can
adapt to your needs).
… Bucket Fill tool options.
This will provide feedback when the line art closure is being computed,
which may be useful on big images where it may take some time. Otherwise
painter may be left hanging without knowing what takes time.
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 GimpBucketFillOptions for the line art algorithm.
Inside GimpLineArt, there are still 2 properties, but we don't show them
anymore in the Bucket Fill tool options. One of the main reason is
probably that it's hard to differentiate their usage. One is to close
with curved lines, the other with straight segments. Yet we don't
actually have any control on one or the other. All one knows is that you
can have "holes" in your drawing of a given size and you want them
close-like for filling. Only reason I can see to have 2 types of closure
is whether you'd want to totally disable one type of closure (then you
set it to 0). But this is a very limited reason for making the options
less understandable overall, IMO.
So for the time being, let's show up only a single option which sets
both properties in GimpLineArt. As patdavid says "it makes sense as a
first pass".
Also rename the option to shorter/simpler "Maximum gap length". Thanks
to patdavid and pippin for helping on figuring out this better label!
Finally I am bumping the default for the gaps to 100px. The original
values were ok for the basic small images used in demos, but not for
real life image where it was always too short (even 100px may still be
too short actually, but much better than the 20 and 60px from before!).
Practically it means that the algorithm won't close line art anymore
with both settings at 0. This can nevertheless still be a very useful
tool when you have a drawing style with well-closed lines. In such a
case, you will still profit from the color flooding under the line art
part of the algorithm.
Moreover with such well-closed zones from start, you don't get the
over-segmentation anymore and the threaded processing will be faster
obviously.
This was my initial choice, but the more I think about it, the less I am
sure this was the right choice. There was some common code (as I was
making a common composite bucket fill once the line art was generated),
but there is also a lot of different code and the functions were filled
of exception when we were doing a line art fill. Also though there is a
bit of color works (the way we decide whether a pixel is part of a
stroke or not, though currently this is basic grayscale threshold), this
is really not the same as other criterions. In particular this was made
obvious on the Select by Color tool where the line art criterion was
completely meaningless and would have had to be opted-out!
This commit split a bit the code. Instead of finding the line art in the
criterion list, I add a third choice to the "Fill whole selection"/"Fill
similar colors" radio. In turn I create a new GimpBucketFillArea type
with the 3 choices, and remove line art value from GimpSelectCriterion.
I am not fully happy yet of this code, as it creates a bit of duplicate
code, and I would appreciate to move some code away from gimpdrawable-*
and gimppickable-* files. This may happen later. I break the work in
pieces to not get too messy.
Also this removes access to the smart colorization from the API, but
that's probably ok as I prefer to not freeze options too early in the
process since API needs to be stable. Probably we should get a concept
of experimental API.
In particular, it allows to easily color pick. This just makes sense as
the bucket fill is definitely what one could call a "color tool", and
being able to easily change color without having to constantly switch to
color picker tool nor open a color chooser dialog is a must.
The fill type option (FG/BG/Pattern) was already mapped to the common
toggle behavior key (Ctrl on Linux), which is commonly used for
switching to color picker on paint tools. So I decided to remap the fill
type switch to GDK_MOD1_MASK (Alt on Linux) to keep consistent with
other tools (at the price of a change for anyone used to this modifier,
though I doubt it was that much used).
I also made possible to combine the 2 modifiers (so you could pick the
foreground or background color with ctrl and ctrl-alt).
When flooding the line art, we may overflood it in sample merge (which
would use color in the line art computation). And if having all colors
on the same layer, this would go over other colors (making the wrong
impression that the line art leaked).
This new option is mostly to keep some control over the mask growth.
Usually a few pixels is enough for most styles of drawing (though we
could technically allow for very wide strokes).
Since commit b00037b850, erosion size is not used anymore, as this step
has been removed, and the end point detection now uses local thickness
of strokes instead.
I have not added all the options for this new tool yet, but this sets
the base. I also added a bit of TODO for several places where we need to
make it settable, in particular the fuzzy select tool, but also simply
PDB calls (this will need to be a PDB context settings.
Maybe also I will want to make some LineArtOptions struct in order not
to have infinite list of parameters to functions. And at some point, it
may also be worth splitting a bit process with other type of
selection/fill (since they barely share any settings anyway).
Finally I take the opportunity to document a little more the parameters
to gimp_lineart_close(), which can still be improved later (I should
have documented these straight away when I re-implemented this all from
G'Mic code, as I am a bit fuzzy on some details now and will need to
re-understand code).

Add an "Antialias" toggle to the bucket fill options and set it on the
GimpFillOptions. In gimp_drawable_bucket_fill(), pass it to
gimp_pickable_contiguous_region_by_seed() instead of always defaulting
to TRUE.
The position of the toggle and its huge tooltip may need some
adjustment.

When checked, diagonally neighboring pixels are considered connected
when calculating the affected area.
This commit also adds a corresponding diagonal_neighbors parameter to
gimp_drawable_bucket_fill(), and modifies the callers, other than the
bucket fill tool, to pass FALSE for this parameter, to retain the
current behavior.

by integrating their label instead of requiring one externally. This
way we get rid of some more labels in the tool options. Also clean up
tool options further (add more spin scales, and some general
reordering and spacing cleanup).
