On-screen keyboard (visible when the feature is enabled, while
using the "Text" and "Label" tools) now appears with larger
(48x48 pixel, vs 24x24 pixel) buttons, when Tux Paint's window
(or fullscreen) size is large enough to fit them with the
chosen layout.
(h/t Anat & Aviv, who suggested it to help with users of
eye-tracking systems)
Also, on-screen keyboard buttons use a slightly larger font
(16pt vs 12pt, previously seen on the small keyboard;
32pt on the large keyboard).
(h/t Jackson Bray for the suggestion)
Also, slight improvements to how circular eraser size calculations
are handled, to allow for radius down to ERASER_MIN of 5.
Adding control buttons to the Shapes tool, allowing for shapes
to be drawn from the center (as before) or from a corner
(more like other paint packages). The controls do nothing
at this time, but are visible and can be clicked. This is a
work in progress.
The controls may be removed using a configuration option.
See "RELEASE.txt" for the invocation. Mended a few things prior
to final run of `tidy`, based on HTML Tidy's output.
Updated any affected TXT files via Makefile.
Planning to run 'tidy' on the HTML doc files. Documenting the
arguments I'm providing to 'tidy', for future reference,
within the RELEASE.txt file.
Also, cleaned up and improved RELEASE.txt.
Tux Paint can export an animated GIF to the export directory
(e.g., ~/Pictures/TuxPaint) from the Open->Slideshow dialog.
To do -- GIF's animated speed should be based on speed slider
in Slideshow dialog.
To do -- Document this new feature (and single image (PNG) export)
in the README documentation.
i18n code was checking for local-related environment variables
(e.g., "getenv("LANGUAGE")") coming back as a NULL if unset.
However, on my laptop, under Kubuntu 20.04 with GLIBC 2.31, a
"LANGUAGE" env. var. is set, but it's blank.
Tux Paint failed to attempt any fallback (e.g., checking "LANG")
in that situation, which was causing the description text corruption
that was corrected in a previous commit.
That commit also mistakenly suggested that the issue might've been a
difference with GCC versions, but the problem was deeper in Tux Paint's
code (in i18n.c), and was triggered by an unexpected environment.
WORK IN PROGRESS -- Attempting to mend an issue where stamp descriptions
are not loading.
Also, making things safer when a problem occurs.
Using gcc 9.3.0 compiler, this was happening in 0.9.25 during
development, but also affected 0.9.24 and 0.9.23, which worked
fine under earlier versions of gcc.
Created "safe_" variations of 'strncpy()', 'strncat()',
and 'snprintf()', to ensure a truncated source string doesn't
leave the destination buffer without a NUL termination character.
Replaced all calls (in "tuxpaint.c" only, so far) to the standard
functions with calls to the new safer versions.
Replaced most calls to plain 'strcpy()', 'strcat()' and
'sprintf()' (which can cause buffer overruns) with the new functions.
From "Open" dialog, select an image (single click, or use
arrow keys / etc., to highlight the image), then select the
"Export" button at the lower right.
The image will be saved in the export directory. By default
this will be based on the config found via the XDG_CONFIG_HOME
environment variable, which is scanned for a "XDG_PICTURES_DIR"
setting. If none is found, "Pictures" in the directory specified
by the HOME env. var. will be used. In both cases, a new
"TuxPaint" subdirectory will be created, and exports will be placed
there.
The export location may be overridden using the "--exportdir"
command-line option or "exportdir" config file option
(e.g., "--exportdir /path/to/dir" or "exportdir=/path/to/dir",
respectively). In this case, the directory is assumed to preexist,
and no "TuxPaint" subdirectory will be made.
There's currently no way to disable the export feature altogether.
If there's demand, we can add it as a simplification option.
Finally, this feature simply copies the PNG file (but no extra
data files) from Tux Paint's "saved" directory to the export dir.
Closes https://sourceforge.net/p/tuxpaint/feature-requests/192/
Using XDG's user dir settings to determine where pictures are
stored for a user (e.g., "~/Pictures" -- used as a fallback).
May be overridden using "--exportdir".
Also, while I was updating some docs, replace references to
"Mac OS X" with "macOS", the new name of that OS these days.
