[Tuxpaint-devel] Tux Paint 0.9.33-rc1 posted for beta builds

[Bill K. <nb...@so...>]

Hi all!  Today I tagged and cut release candidates of Tux Paint 0.9.33
and friends:

 * Tux Paint 0.9.33-rc1
   https://sourceforge.net/projects/tuxpaint/files/tuxpaint/0.9.33-beta/tuxpaint-0.9.33-rc1.tar.gz/download

 * Tux Paint Config 0.0.24-rc1
   https://sourceforge.net/projects/tuxpaint/files/tuxpaint-config/0.0.24-beta/tuxpaint-config-0.0.24-rc1.tar.gz/download

 * Tux Paint Stamps 2024-07-XX-rc1
   https://sourceforge.net/projects/tuxpaint/files/tuxpaint-stamps/2024-07-XX-beta/tuxpaint-stamps-2024.07.06.tar.gz/download

When you have time, please build versions based on these for your favorite
platform, so we can have people beta test them.

Tux Paint includes a number of changes and bugfixes since the last
release, back in January:

 * A pair of new "Dither" magic tools
 * New "Filled Polygon" magic tool
 * New magic tool API call to retract an undo snapshot
   (utilized by "Filled Polygon")
 * Update to "3D Glasses" magic tool
 * Option to un-group (one big list, no pagination) Magic tools
 * Some new, transparent, erasers
 * A few new brushes (Paint & Line tools)
 * Brushes can have descriptions
 * Font face/size shown when choosing/changing a font (Text & Label tools)
 * Click-and-release (no drag) with rotating brush would not draw anything;
   now it draws as if you dragged "up"
 * Labels on UI buttons will now also word-wrap on dashes ("-"),
   and support Unicode soft hyphens to hint where words may be broken
 * When exporting a drawing (via "Open" dialog), the name of the file
   is shown, AND is placed in your Copy/Paste buffer
 * OS Trashcan support ("Erase" in "Open" dialog) on Haiku now, too
 * Snappier screen refresh on macOS
 * Workaround for bash-completion (newer versions) bug in some locales
   (was due to Tux Paint's file being read before bash-completion's own
   "000_bash_completion_compat.bash")
 * Some work towards supporting OS/2 builds
 * Universal bundling simplification for macOS
 * Appdate metadata updates for Appstream 1.0
 * Remove final coupla of RSVG library warnings during compliation
 * Removed some unused text rendering code
 * Updated Troubleshooting Guide to cover macOS, Haiku, and Linux
 * Docs made more consistent, re: where files go
 * Added process to run `indent` on "tp_magic_example.c" regularly
 * Doc styling modernization in FAQ, Env. Vars., & Advanced Stamp Howto.
 * Doc corrections re: old usage of "--fullscreen" (with no parameter)
 * Localization updates
 * Bugfix: Avoid invalid memory access in Linear Gradient (Fill tool)

WHEW!  It's a lot!  Despite feeling like I haven't done anything with
Tux Paint for a few months, I guess the truth is we were REALLY busy
in the beginning of the year. :-)


Tux Paint Config. adds a new checkbox (in "Simplification") for the
magic tool ungrouping feature.  Otherwise, both Config. Tux Paint Stamps
only had some localization updates since their last releases
(also back in January).

Thanks in advance!  For others up here in the northern hemisphere,
I hope you're staying safe & cool!

Thanks!  For safety, I made the two arrays larger by one, since the
last thing that happens is one _more_ point is created, which has
the same position as the first point (index 0).  So if I were to add
a new point at MAX_PTS index into the array, that would go beyond
its capacity, otherwise.

I also bumped the number of points up to 100. (I did that last night
but forgot to commit. Zzzz)

I think I understand what you mean.  I need to play with it
more to make sure, and then I'll see what I can do.  At this
point, I'm glad that it seems to be working _at all_, though...
so any further improvements are just a bonus, IMO. :-D

It's the only time I get to really hack on Tux Paint these days.

Better :)
Could be improved if a click in the starting point closes the polygon, 
as it is now you have to click outside the starting point and drag into it,
the following works for me.

Works fine as far as I've tested :), the only improvement I could imagine 
is to use the first Undo just to clear the auxiliary stuff, 
withouth undoing previous work, other Undo acting as of now.

I think we can raise the number of points.  In the meantime, I updated it
so that clicking again will simply move the end point (rather than silently
and confusingly doing _nothing_).

Okay, I've made an attempt to prevent the previews from landing in the
undo history.  This is via a new Magic API function that magic tools may
call: api->retract_undo().  It basically just rolls back `cur_undo` and
`newest_undo` by one, so whatever was just snapped (during a mousedown
event, just prior to the Magic tool's `_click()` from being called)
gets "forgotten".

So for example, I can click a bunch of times to make a new polygon,
and when I hit Undo, it goes back to the canvas as it appeared before
I added the very first point.  And when I hit Redo, the entire polygon
reappears in its final (non-preview) form.

HOPEFULLY this works well.  It's almost 2am, and I was tired many hours
_before_ I tried tackling this. :-D

Before I go to bed I'm going to add info about this to the API docs.
Hopefully in the next few days I can see about utilizing this with
other Magic tools that offer "previews" that live beyond the
(1) click, (2) drag, (3) release lifespan (e.g., Clone, and the
Perspective drawing tools)... so they will stop "corrupting" the
Undo history with their outline and crosshair nonsense. ;-)

This is quite a hack, I admit, so wish me luck!

And PLEASE TEST!  Bang on it as much as you can, and report back!

I spoke too fast :( 
There is also the possibility of removing one or more points
that will let you be able to add some new ones.

Removing points is not mentioned in the UI tool description.

Re: [Tuxpaint-devel] Polygon fill messing with other tools drawing

[Pere P. i C. <per...@gm...>]

Hi Bill, and all,

A problem, start drawing a polygon and do as many points as possible (17?) 
then you are blocked, you can either switch out of the tool or drag the 
latest point to the origin closing the polygon, which is not very intuitive.
Assuming the only thing you can do in the tool is to close the polygon, 
I suggest to do this automatically.

Then there is the interaction with the Undo tool: draw say 5 points and go 
to another tool without closing the polygon, the helper lines and points 
disappear (by design?), hit Undo and they reappear, 
I'd suggest to either keep them in the drawing or erase them from the undo stack.

Hi Pere (and everyone),

I'd appreciate if you could test the Filled Polygon tool some more.
Also, please enjoy (and report any issues with!) some sound effects
that I just added.

There are different sounds for

 * adding a new point
 * dragging the new point / moving an existing one
 * dragging either end point next to the other, when 3+ points exist
   (you are "at risk" of completing the polygon ;) )
 * dragging one point into another, thus merging them
   (removing a point)
 * completing the polygon


I'm hoping to release a new version of Tux Paint soon,
ahead of a busy summer.  I'll post to -i18n and -maintainers
about this fact. :)

Oh, I thouth it was on purpose, to let children with something painted 
on the screen, in fact the Undo tool still recovers them.

Currently magic tools that need multiple clicks to do their work 
are tricky, especially when faced to the Undo tool.

For now, I've set a variable to tell whether switchin() has been
called yet.  To me, it seems strange that I'm calling a Magic tool's
set_color() BEFORE its switchin() has been called.  But rather than
change that (and potentially break lots of other tools), I've opened a
ticket. :-)

  https://sourceforge.net/p/tuxpaint/bugs/286/

I also addressed an issue I already knew about, where the in-progress
polygon preview (the lines and big red & green boxes) would remain on
the canvas when switching to a different tool.

I believe I solved that by simply blitting the tool's own snapshot
back to the canvas on switchout().  (And since it makes a fresh
snapshot after every polygon has been completed, this works.)

Adjustments like this may help some of the other Magic tools that
"act weird" when you're in the middle of using them, but then
switch away.

I've also thought it might be nice to provide a way for Magic
tools to say "I can handle the 'Undo' command myself", e.g.
for Filled Polygon tool, it would remove the most-recently
added point.  Then, if there's no more work for them to do,
they can tell Tux Paint that it should do it's normal Undo
process.

Prior to that, I also thought it might be interesting to provide a
way for Magic tools to provide an 'overlay' SDL_Surface which
Tux Paint would draw on top everything else, rather than having
to abuse the main `canvas` surface to draw previews, crosshairs,
grids, etc.

Things are getting tricky. :)

[Tuxpaint-devel] Polygon fill messing with other tools drawing

[Pere P. i C. <per...@gm...>]

Hi all,

Tested the new polyfill stuff, it is nice :)

Just found a minor problem:
Start Tux Paint, select the Polygon Fill tool.
select another tool and draw something.
Return to the Polygon Fill tool, see how everything you had drawn is lost.

The problem is polyfill_snapshot being kept and later blit into the canvas via
set_color() -> draw_preview() before switchin()

We could clean up polyfill_snapshot at switchout() and recreate it at each swcithin() or
we could set some marker, mark it at switchout, clean it up at switchin() and only blit polyfill_snapshot
if the marker allows it, that would allow to reuse polyfill_snapshot and not destroy/recreate it
at each switchout()/switchin() cycle.

Mended, thanks!  I glanced over the rest of the code for

[Tuxpaint-devel] magic di/tri metric some strings may be changed from click to click and drag?

[Pere P. i C. <per...@gm...>]

Hi all,

Dimetric selection:
Click in your drawing to adjust the angle used by the dimetric projection
Just clicking works sometimes, click and drag works always.

Same for Oblique selection.

Trimetric selection:
Click in your drawing to adjust the angles used by the trimetric projection painting tool.
Only click works very few times, click-pointing the lines and drag them works always.

[Tuxpaint-devel] 2-points selection freezes when joining the 2 points

[Pere P. i C. <per...@gm...>]

Just found this: magic 2-point selection, if you let one of the points in place 
and drag the other next/over to it, Tux Paint freezes.

I've not been able to reproduce with 3-points selection.

[Tuxpaint-devel] Magic tools now report an "order" integer

[Bill K. <nb...@so...>]

Magic tools are now queried for an 'order' value (an integer),
which is used as the sorting method for organizing the various
tools within each group.

I've just assigned some values to every single Magic tool
in every plugin (.c) file.  Whew!

This allows us to place related Magic tools next to each
other, rather than having them organized somewhat arbitrarily
by their name (which of course differs for each language!)

I've been thinking about doing this, especially after adding
numerous related tools which make sense to list in a certain
order (Isometric, Dimetric, Trimetric, Oblique), rather
than alphabetically (in English, they appeared in the order:
Dimetric, Isometric, Oblique, Trimetric).  Thanks to Shin-ichi
for mentioning this, which was the nudge I needed to actually
get it done. ;)

Note that the numbers are relative to other tools within the
same group, and remember that a particular plugin source file
may place tools in different groups than each other.
(For exmaple, "swirls.c" has both the "Circles" and "Rays"
distortion effects, and the "Fur" painting tool.)

I thought about creating a 'global' header file for
the entire set of Magic tools that ship with Tux Paint,
but since it was already an overwhelming task to modify
62 source files, AND think about how to organize the
approx. ten dozen tools, I figured this was good enough
for now.  Time for bed. :-)

Please try it out and let me know if you notice any
issues, or have suggestions on how to improve the
ordering of things.

(This WILL have a "who moved my cheese!?" effect on users,
but frankly so does adding new Magic tools, which get
inserted in the groups... and so did adding groups to
begin with!)

At first, Tuxpaint crashed every time when "ARTISTIC" group was selected.
After that I once removed tuxpaint.cfg (I should have keep it's copy....) seeing
above strange value for complexity. Then, I've lost the way to reproduce the crash.

Sorry for the vague information.

Hrm I was able to replicate it by leaving the setting
blank (which should NOT have been an option -- I forgot to
add the new widget to the appropriate routine in `defaults.cxx`),
then change something else so I could click "Apply" to save.

I _believe_ I've corrected it. Please `git pull` and rebuild, and
tell me if you can still replicate it :)

Hrm, I cannot replicate in Linux.  I tried all three of the new
complexity levels.

Oh, question -- did you rebuild all of the Magic tools from scratch?
(Hrm, I suppose you must have, for them to load at all, since they
need to match the Magic API version.)  Hmm... please tell me what
you discover.

Luc, Mark, and Pere, when you have time can you also test the new
features on Haiku, macOS, and Android?

Thanks in advance!

Re: [Tuxpaint-devel] New perspective drawing tools & complexity setting

[Shin-ichi T. <dol...@wm...>]

Hi!

I noticed that complexity is incorrectly set to "qwerty.layout" in personal config file.

This happens with following steps.

 1) start tuxpaint-config
 2) set complexity to "(no override).
 3) apply and quit.
 4) start tuxpaint-config
 5) change any setting other than complexity.
 6) apply and quit

In addition, I observed crash on windows when switching magic tool categories.
Unfortunately I have not found the step to reproduce it so far.

[Tuxpaint-devel] Complexity setting (was re: 1-, 2-, and 3-point perspective line drawing Magic tools)

[Bill K. <nb...@so...>]

Hi again and happy new year!

I've updated Tux Paint to offer a new "complexity" (aka "expertise level")
setting, which allows Magic tool plugins to respond differently based
on the user's setting: novice, beginner, or advanced (the default).

Tools can behave differently, or disappear completely, based on this.

The simplest example of this is an update I made to the "Clone"
(sheep) tool.  In 'novice' mode, it's not available at all.  I decided
that the method of using it, and what exactly it's doing to your
picture, are a little confusing -- compared to, for example, painting
a rainbow or smuding your picture, which are straightforward, and
their effects are obvious.

The motivation for this feature was my new 1-, 2-, and 3-point
perspective tools; see my previous post, a snippet of which is here:

<snip>

These three tools actually appear as pairs of tools: one to draw
(e.g., "2-Point Draw"), and one to adjust the vanishing point(s)
(e.g., "2-Point Select").

Similar to the "Clone" tool, I decided the vanishing point drawing
tools, as whole, are probably too complex for some users, so they
will not be available in "novice" mode.

In "advanced" mode, they appear as they were originally designed.
Six tools appear, three to draw, and three to adjust their
respective vanishing point(s).

In "beginner" mode, ONLY the drawing tools will appear.  The vanishing
points are fixed, and cannot be edited.

Beyond that, though, a fourth drawing tool is made available: another
3-point perspective, but with an alternative set of hard-coded
vanishing points.  The default vanishing points were set up for drawing
from the perspective of looking up from the below; the additional tool
has alternative vanishing points, for looking down from above.

(Think: looking up at the Eiffel Tower, versus looking down from on top
of it.)

The command-line and configuration option is called "complexity", and
accepts the argument "advanced" (default; useful to override if a
system-level config. has set something lower), "beginner", and "novice".

I currently cannot think of a reason to add further granularity.
I also haven't yet put much thought into other tools that may benefit
from offering different behavior in "beginner" or "novice" modes,
but I'm open to suggestions!

The man page, bash tab completion, OPTIONS docs, Tux Paint Config.
(and its own docs), and the various Magic tool doc pages for the
affected tools have all been updated to reflect these changes.

Thanks as always for everyone's help with the project, and here's
to a healthy and prosperous 2024!

[Tuxpaint-devel] 1-, 2-, and 3-point perspective line drawing Magic tools

[Bill K. <nb...@so...>]

Happy holidays!  ICYMI, I've recently added three pairs of new
Magic tools that allow you to draw diagrams using 1-, 2-, and
3-point perspective, and to adjust the vanishing point(s) for
those three drawing tools.

They're a _little_ finnicky, but seem to work okay for now.
I'd be happy letting them loose into the world as-is, and
get feedback from "actual artists" (i.e., "not me") as to their
effectiveness.

In the meantime, you can see a demo of them here (note: I was
using a mouse, and my left button seemed to be dirty & acting up;
perfect timing :eyeroll:)

  https://www.youtube.com/watch?v=r3GyrmWDxcQ

This was inspired by some videos I saw of Krita, which has some
"guide" features which allow for the same kind of perspective
drawing technique.  My hope is that this can be used to help
educate kids learning art.  (A lot of things I've added to
Tux Paint are just "fun", or "in the style of {some artist or
art style}"... but things like this, and the Color Mixer tool,
are meant to be slightly more educational... hopefully ;-) )

Enjoy, and let me know what you think.  Code improvements
welcome.  As usual, I've often done this late at night
(in bed, even!), and I never took a Trigonometry class
(and I had, it would've been 30 years ago :-D ... my day job
does not involve this kind of math, hehehe)

[Tuxpaint-devel] "Having Problems?" page

[Bill K. <nb...@so...>]

We occassionally hear from users who have trouble starting Tux Paint,
or have other issues which might be solved by resetting their
configuration, removing corrupted or crash-causing drawings or other
files, and which we'd benefit from seeing their config & drawings, and
also log files (stdout/stderr output).

Shin-ichi had a very good set of questions he sent a user recently,
so I decided to formalize it so we can simply share a web page with
users, rather than having to copy/paste instructions, or rewrite them
each time. :)

Mark Kim provided some similar information for macOS.  Luc, if you
want to provide some info for Haiku, I can add it to the page too!

If anyone has questions, suggestions, or other feedback, please let
me know and I can try and integrate it.  Thanks,
