Replaced Spanish w/ new content from tuxpaint-docs

Browse source 
Some already-translated (but very out-of-date) content
has been replaced with not-yet-translated (i.e., English) content.

Translators may want to look at the previous revisions of these
files when translating the new 'tuxpaint-docs' gettext catalog.
Sorry to cause extra work here, if I've done so.

----------------------------------------------------------------------
If you wish to add or change things like Brushes, Starters, Rubber Stamps,
and other content used by Tux Paint, you can do so fairly easily by simply
adding, changing, or removing files where Tux Paint looks for them.
Note: You'll need to re-launch Tux Paint for the changes to take effect.
----------------------------------------------------------------------
Where Files Go
Standard Files
Tux Paint looks for its various data files in its 'data' directory.
Linux and Unix
Where this directory goes depends on what value was set for
"DATA_PREFIX" when Tux Paint was built. See 'Install documentation'
for details.
By default, though, the directory is:
/usr/local/share/tuxpaint/
If you installed from a package, it is more likely to be:
/usr/share/tuxpaint/
Windows
Tux Paint looks for a directory called 'data' in the same directory
as the executable. This is the directory that the installer used
when installing Tux Paint e.g.:
C:\Program Files\TuxPaint\data
macOS
Tux Paint stores its data files inside the "Tux Paint" application
icon (which is actually a special kind of folder on macOS & Mac OS X
before it). The following steps explain how to get to the folders
within it:
1. Bring up a 'context' menu by holding the [Control] key and
clicking the Tux Paint icon the in Finder. (If you have a mouse
with more than one button, you can simply right-click the icon.)
2. Select "Show Contents" from the menu that appears. A new Finder
window will appear with a folder inside called "Contents".
3. Open the "Contents" folder and open the "Resources" folder found
inside.
4. There, you will find various sub-folders, such as "starters",
"stamps", "brushes", etc. Adding new content to these folders
will make the content available to any user that launches this
copy (icon) of Tux Paint.
Note: If you install a newer version of Tux Paint and replace or
discard the old version, you will lose changes made by following the
instructions above, so keep backups of your new content (stamps,
brushes, etc.).
Tux Paint also looks for files in a "TuxPaint" folder that you can
place in your system's "Application Support" folder (found under
"Library" at the root of your filesystem):
/Library/Application Support/TuxPaint/
When you upgrade to a newer version of Tux Paint, the contents of
this "TuxPaint" folder will stay the same, and remain accessible by
all users of Tux Paint.
----------------------------------------------------------------------
Personal Files
You can also create brushes, stamps, 'starters', templates, and fonts
in your own user account directory (folder) for Tux Paint to find.
Windows
Your personal Tux Paint folder is stored in your personal
"Application Data". For example, on newer Windows:
C:\Documents and Settings\(username)\Application Data\TuxPaint\
macOS
Your personal Tux Paint folder is stored in your personal
"Application Support" folder:
/Users/(username)/Library/Application Support/TuxPaint/
Linux and Unix
Your personal Tux Paint files go into a 'hidden directory' found in
your account's home directory: "$(HOME)/.tuxpaint/" (also known as
"~/.tuxpaint/").
That is, if your home directory is "/home/tux", then your personal
Tux Paint files go in "/home/tux/.tuxpaint/".
Don't forget the period (".") before the "tuxpaint"!
To add your own brushes, stamps, 'starters,' templates, and fonts,
create subdirectories under your personal Tux Paint directory named
"brushes", "stamps", "starters", "templates", "fonts", respectively.
(For example, if you created a brush named "flower.png", you would put
it in "~/.tuxpaint/brushes/" under Linux or Unix.)
----------------------------------------------------------------------
Brushes
The brushes used for drawing with the 'Brush' and 'Lines' tools in Tux
Paint are simply PNG image files.
The alpha (transparency) of the PNG image is used to determine the shape
of the brush, which means that the shape can be 'anti-aliased' and even
partially-transparent!
Greyscale pixels in the brush PNG will be drawn using the
currently-selected color in Tux Paint. Color pixels will be tinted.
Brush Options
Aside from a graphical shape, brushes can also be given other
attributes. To do this, you need to create a 'data file' for the
brush.
A brush's data file is simply a plain ASCII text file containing the
options for the brush.
The file has the same name as the PNG image, but a ".dat" extension.
(e.g., "brush.png"'s data file is the text file "brush.dat", found in
the same directory.)
Brush Spacing
As of Tux Paint version 0.9.16, you can now specify the spacing for
brushes (that is, how often they are drawn). By default, the spacing
will be the brush's height, divided by 4.
Add a line containing the line "spacing=N" to the brush's data file,
where "N" is the spacing you want for the brush. (The lower the
number, the more often the brush is drawn.)
Animated Brushes
As of Tux Paint version 0.9.16, you may now create animated brushes.
As the brush is used, each frame of the animation is drawn.
Lay each frame out across a wide PNG image. For example, if your
brush is 30x30 and you have 5 frames, the image should be 150x30.
Add a line containing the line "frames=N" to the brush's data file,
where "N" is the number of frames in the brush.
Note: If you'd rather the frames be flipped through randomly, rather
than sequentially, also add a line containing "random" to the
brush's data file.
Directional Brushes
As of Tux Paint version 0.9.16, you may now create directional
brushes. As the brush is used, different shapes are drawn, depending
on the direction the brush is going.
The directional shapes are divided into a 3x3 square in a PNG image.
For example, if your brush is 30x30, the image should be 90x90, and
each of the direction's shapes placed in a 3x3 grid. The center
region is used for no motion. The top right is used for motion
that's both up, and to the right. And so on.
Add a line containing the word "directional" to the brush's data
file.
Animated Directional Brushes
You may mix both animated and directional features into one brush.
Use both options ("frames=N" and "directional"), in separate lines
in the brush's ".dat" file.
Lay the brush out so that each 3x3 set of directional shapes are
laid out across a wide PNG image. For example, if the brush is 30x30
and there are 5 frames, it would be 450x90. (The leftmost 150x90
pixels of the image represent the 9 direction shapes for the first
frame, for example.)
Place the brush image PNGs (and any data text files) in the "brushes"
directory.
Note: If your new brushes all come out as solid squares or rectangles,
it's because you forgot to use alpha transparency! See the 'PNG
documentation' in Tux Paint for more information and tips.
----------------------------------------------------------------------
Stamps
All stamp-related files go in the "stamps" directory. It's useful to
create subdirectories and sub-subdirectories there to organize the
stamps. (For example, you can have a "holidays" folder with "halloween"
and "christmas" sub-folders.)
Stamp Images
Rubber Stamps in Tux Paint can be made up of a number of separate
files. The one file that is required is, of course, the picture
itself.
As of Tux Paint version 0.9.17, Stamps may be either PNG bitmap images
or SVG vector images. They can be full-color or greyscale. The alpha
(transparency) channel of PNGs is used to determine the actual shape
of the picture (otherwise you'll stamp a large rectangle on your
drawings).
PNGs can be any size, and Tux Paint (by default) provides a set of
sizing buttons to let the user scale the stamp up (larger) and down
(smaller).
SVGs are vector-based, and will be scaled appropriately for the canvas
size being used in Tux Paint.
Note: If your new PNG-based stamps all come out as solid squares or
rectangles, it's because you forgot to use alpha transparency! See the
'PNG documentation' in Tux Paint for more information and tips.
Note: If your new SVG stamps seem to have a lot of whitespace, make
sure the SVG 'document' is no larger than the shape(s) within. If they
are being clipped, make sure the 'document' is large enough to contain
the shape(s). See the 'SVG documentation' in Tux Paint for more
information and tips.
Advanced Users: The 'Advanced Stamps How-To' document describes, in
detail, how to make PNG images which will scale perfectly when used as
stamps in Tux Paint.
----------------------------------------------------------------------
Stamp Descriptive Text
Tux Paint will display descriptive text when a stamp is selected.
These are placed in plain text files with the same name as the PNG or
SVG, but with a ".txt" filename extension. (e.g., "stamp.png"'s
description is stored in "stamp.txt" in the same directory.)
The first line of the text file will be used as the US English
description of the stamp's image. It must be encoded in UTF-8.
Localization Support
Additional lines can be added to the text file to provide
translations of the description, to be displayed when Tux Paint is
running in a different locale (like French or Spanish).
The beginning of the line should correspond to the language code of
the language in question (e.g., "fr" for French, and "zh_TW" for
Traditional Chinese), followed by ".utf8=" and the translated
description (Unicode, encoded in UTF-8).
For Tux Paint developers: There are scripts in the "po" directory
for converting the text files to PO format (and back) for easy
translation to different languages. Therefore you should never add
or change translations in the ".txt" files directly.
If no translation is available for the language Tux Paint is
currently running in, the US English text is used.
Windows Users
Use NotePad or WordPad to edit/create these files. Be sure to save
them as plain-text, and make sure they have a ".txt" extension at
the end of the filename.
----------------------------------------------------------------------
Stamp Sound Effects
Tux Paint can play a sound effect when a stamp is selected. For
example, the sound of a duck quaking when selecting a duck, or a brief
piece of music when a musical instrument is chosen. Files may be in
"WAVE (".wav")" or "OGG Vorbis (".ogg")" formats, and are given same
name as the PNG or SVG image. (e.g., "stamp.svg"'s sound effect is the
sound file "stamp.ogg" in the same directory.)
Localization Support
For sounds for different locales (e.g., if the sound is someone
saying a word, and you want translated versions of the word said),
also create WAV or OGG files with the locale's label in the
filename, in the form: "stamp_LOCALE.EXT"
"stamp.png"'s sound effect, when Tux Paint is run in Spanish mode,
would be "stamp.png". In French mode, "stamp_es.wav". In Brazilian
Portuguese mode, "stamp_fr.wav". And so on...
If no localized sound effect can be loaded, Tux Paint will attempt
to load the 'default' sound file. (e.g., "stamp.wav")
Note: For descriptive sounds (not sound effects, like a bang or a bird
chirping), consider using descriptive sounds; see 'Stamp Descriptive
Sound', below.
----------------------------------------------------------------------
Stamp Descriptive Sound
Tux Paint can also play a descriptive sound when a stamp is selected.
For example, the sound of someone saying the word "duck" when
selecting a duck, or the name of a musical instrument when one is
chosen. Files may be in "WAVE (".wav")" or "OGG Vorbis (".ogg")"
formats, and are given same name as the PNG or SVG image, with "_desc"
at the end. (e.g., "stamp.svg"'s descriptive sound is the sound file
"stamp_desc.ogg" in the same directory.)
Localization Support
For descriptive sounds for different locales, also create WAV or OGG
files with both "_desc" and the locale's label in the filename, in
the form: "stamp_desc_LOCALE.EXT"
"stamp.png"'s descriptive sound, when Tux Paint is run in Spanish
mode, would be "stamp_desc_es.wav". In French mode,
"stamp_desc_fr.wav". In Brazilian Portuguese mode,
"stamp_desc_pt_BR.wav". And so on...
If no localized descriptive sound can be loaded, Tux Paint will
attempt to load the 'default' sound file. (e.g., "stamp_desc.wav")
----------------------------------------------------------------------
Stamp Options
Aside from a graphical shape, a textual description, a sound effect,
and a descriptive sound, stamps can also be given other attributes. To
do this, you need to create a 'data file' for the stamp.
A stamp's data file is simply a plain ASCII text file containing the
options for the stamp.
The file has the same name as the PNG or SVG image, but a ".dat"
extension. (e.g., "stamp.png"'s data file is the text file
"stamp.dat", found in the same directory.)
Colored Stamps
Stamps can be made to be either "colorable" or "tintable."
Colorable
"Colorable" stamps they work much like brushes - you pick the
stamp to get the shape, and then pick the color you want it to be.
(Symbol stamps, like the mathematical and musical ones, are an
example.)
Nothing about the original image is used except the transparency
(from "alpha" channel). The color of the stamp comes out solid.
Add a line containing the word "colorable" to the stamp's data
file.
Tinted
"Tinted" stamps are similar to "colorable" ones, except the
details of the original image are kept. (To put it technically,
the original image is used, but its hue is changed, based on the
currently-selected color.)
Add a line containing the word "tintable" to the stamp's data
file.
Tinting Options:
Depending on the contents of your stamp, you might want to have
Tux Paint use one of a number of methods when tinting it. Add
one of the following lines to the stamp's data file:
Normal tinter — "tinter=normal" (the default)
This is the normal tinting mode. (Hue range is ±18°, 27
replace.)
'Any hue' tinter — "tinter=anyhue"
This remaps all hues in the stamp. (Hue range is ±180°.)
Narrow tinter — "tinter=narrow"
This like the "anyhue" option, but with a narrower hue
angle. (Hue range is ±6°, 9 replace.)
Vector tinter — "tinter=vector"
This maps 'black through white' to 'black through
destination'.
Unalterable Stamps
By default, a stamp can be flipped upside down, shown as a mirror
image, or both. This is done using the control buttons below the
stamp selector, at the lower right side of the screen in Tux Paint.
Sometimes, it doesn't make sense for a stamp to be flippable or
mirrored; for example, stamps of letters or numbers. Sometimes
stamps are symmetrical, so letting the user flip or mirror them
isn't useful.
To prevent a stamp from being flipped vertically, add the option
"noflip" to the stamp's data file.
To prevent a stamp from being mirrored horizontally, add the option
"nomirror" to the stamp's data file.
Initial Stamp Size
By default, Tux Paint assumes that your stamp is sized appropriately
for unscaled display on a 608x472 canvas. This was the original Tux
Paint canvas size, provided by a 640x480 screen. Tux Paint will then
adjust the stamp according to the current canvas size and, if
enabled, the user's stamp size controls.
If your stamp would be too big or too small, you can specify a scale
factor. If your stamp would be 2.5 times as wide (or tall) as it
should be, add one of the following options, which represent the
same adjustment, to the stamp's data file. (An equals sign, "=", may
be included after the word "scale".)
* "scale 40%"
* "scale 5/2"
* "scale 2.5"
* "scale 2:5"
Windows Users
Use NotePad or WordPad to edit/create these files. Be sure to save
them as plain-text, and make sure they have a ".txt" extension at
the end of the filename.
Pre-Mirrored and Flipped Stamps
In some cases, you may wish to provide a pre-drawn version of a
stamp's mirror-image, flipped image, or even both. For example,
imagine a picture of a fire truck with the words "Fire Department"
written across the side. You probably do not want that text to appear
backwards when the image is flipped!
To create a mirrored version of a stamp that you want Tux Paint to
use, rather than mirroring one on its own, simply create a second
".png" or ".svg" graphics file with the same name, except with
"_mirror" before the filename extension.
For example, for the stamp "stamp.png" you would create another file
named "stamp_mirror.png", which will be used when the stamp is
mirrored (rather than using a backwards version of "stamp.png").
As of Tux Paint 0.9.18, you may similarly provide a pre-flipped image
with "_flip" in the name, and/or an image that is both mirrored and
flipped, by naming it "_mirror_flip".
Note: If the user flips and mirrors an image, and a pre-drawn
"_mirror_flip" doesn't exist, but either "_flip" or "_mirror" does, it
will be used, and mirrored or flipped, respectively.
----------------------------------------------------------------------
Fonts
The fonts used by Tux Paint are TrueType Fonts (TTF).
Simply place them in the "fonts" directory. Tux Paint will load the font
and provide four different sizes in the 'Letters' selector when using
the 'Text' and 'Label' tools.
----------------------------------------------------------------------
'Starters'
'Starter' images appear in the 'New' dialog, along with solid color
background choices.
When you use a 'starter' image, make modifications, and save it, the
original 'starter' image is not overwritten. Additionally, as you edit
your new picture, the contents of the original 'starter' can affect it.
Coloring-Book Style Starters
The most basic kind of 'starter' is similar to a picture in a coloring
book. It's an outline of a shape which you can then color in and add
details to. In Tux Paint, as you draw, type text, or stamp stamps, the
outline remains 'above' what you draw. You can erase the parts of the
drawing you made, but you can't erase the outline.
To create this kind of 'starter' image, simply create an outlined
black and white picture in a paint program, and save it as a raster
PNG file, or vector SVG. If saving as a PNG, you may optionally render
the image as black-and-transparent, rather than black-and-white, but
(as of Tux Paint 0.9.21) this is not required.
Scene-Style Starters
Along with the 'coloring-book' style overlay, you can also provide a
separate background image as part of a 'starter' picture. The overlay
acts the same: it can't be drawn over, erased, or affected by 'Magic'
tools. However, the background can be!
When the 'Eraser' tool is used on a picture based on this kind of
'starter' image, rather than turning the canvas to a solid color, such
as white, it returns that part of the canvas to the original
background picture from the 'starter' image.
By creating both an overlay and a background, you can create a
'starter' which simulates depth. Imagine a background that shows the
ocean, and an overlay that's a picture of a reef. You can then draw
(or stamp) fish in the picture. They'll appear in the ocean, but never
'in front of' the reef.
To create this kind of 'starter' picture, simply create an overlay
(with transparency) and save it as a PNG. Then create another image
(without transparency), and save it with the same filename, but with
"-back" (short for 'background') appended to the name. (e.g.,
"starter-back.png" would be the background ocean picture that
corresponds to the overlay, or foreground.)
For best results, 'starter' images should be at least the same size as
Tux Paint's drawing canvas. (See the "Loading Other Pictures into Tux
Paint" section of Tux Paint's main documentation (README) for details on
sizing.) If they are not, they will be stretched or scaled. This is done
without affecting the shape ("aspect ratio"); however some smudging may
be applied to the edges.
Place them in the "starters" directory. When the 'New' dialog is
accessed in Tux Paint, the 'starter' images will appear in the screen
that appears, after the various solid color choices.
Note: 'Starters' are 'attached' to saved pictures, via a small text file
that has the same name as the saved file, but with ".dat" as the
extension. This allows it to continue to affect the drawing even after
Tux Paint has been quit, or another picture is loaded or a new image is
created. (In other words, if you base a drawing on a 'starter' image, it
will always be affected by it.)
----------------------------------------------------------------------
'Templates'
'Template' images also appear in the 'New' dialog, along with solid
color background choices and 'Starters'. (Note: Tux Paint prior to
version 0.9.22 did not have the 'Template' feature.)
Unlike pictures drawn in Tux Paint by users and then opened later,
opening a 'template' creates a new drawing. When you save, the
'template' image is not overwritten. Unlike 'starters', there is no
immutable 'layer' above the canvas. You may draw over any part of it.
When the 'Eraser' tool is used on a picture based on this kind of
'template' image, rather than turning the canvas to a solid color, such
as white, it returns that part of the canvas to the original background
picture from the 'template' image.
'Templates' are simply image files (in PNG, JPEG, SVG, or KPX (KidPix)
format). No preparation or conversion should be required.
For best results, 'template' images should be at least the same size as
Tux Paint's drawing canvas. (See the "Loading Other Pictures into Tux
Paint" section of Tux Paint's main documentation (README) for details on
sizing.) If they are not, they will be stretched or scaled. This is done
without affecting the shape ("aspect ratio"); however some smudging may
be applied to the edges.
Place them in the "templates" directory. When the 'New' dialog is
accessed in Tux Paint, the 'template' images will appear in the screen
that appears, after the various solid color choices.
Note: 'Templates' are 'attached' to saved pictures, via a small text
file that has the same name as the saved file, but with ".dat" as the
extension. This allows it to continue to affect the drawing even after
Tux Paint has been quit, or another picture is loaded or a new image is
created. (In other words, if you base a drawing on a 'template' image,
it will always be affected by it.)
----------------------------------------------------------------------
Translations
Tux Paint supports numerous languages, thanks to use of the "gettext"
localization library. (See "Options documentation" for how to change
locales in Tux Paint.)
To translate Tux Paint to a new language, copy the translation template
file, "tuxpaint.pot" (found in Tux Paint's source code, in the folder
"src/po/"). Rename the copy as a ".po" file, with an appropriate name
for the locale you're translating to (e.g., "es.po" for Spanish; or
"pt_BR.po" for Brazilian Portuguese, versus "pt.po" or "pt_PT.po" for
Portuguese spoken in Portugal.)
Open the newly-created ".po" file — you can edit in a plain text edtior,
such as Emacs, Pico or VI on Linux, or NotePad on Windows. The original
English text used in Tux Paint is listed in lines starting with "msgid".
Enter your translations of each of these pieces of text in the empty
"msgstr" lines directly below the corresponding "msgid" lines. (Note: Do
not remove the quotes.)
Example:
msgid "Smudge"
msgstr "Manchar"
msgid "Click and drag to draw large bricks."
msgstr "Haz clic y arrastra para dibujar ladrillos grandes."
Various tools exist to manage gettext translation catalogs, so you don't
have to edit them by hand in a text editor. Here are a few:
* Poedit
* Gtranslator (GNOME Translator)
* Virtraal
* Lokalize
Note: It is best to always work off of the latest Tux Paint text catalog
template ("tuxpaint.pot"), since new text is added, and old text is
occasionally changed. The text catalog for the upcoming, unreleased
version of Tux Paint can be found in Tux Paint's Git repository (see:
http://www.tuxpaint.org/download/source/git/), and on the Tux Paint
website at http://www.tuxpaint.org/help/po/.
To edit an existing translation, download the latest ".po" file for that
language, and edit it as described above.
You may send new or edited translation files to Bill Kendrick, lead
developer of Tux Paint, at: bill@newbreedsoftware.com, or post them to
the "tuxpaint-i18n" mailing list (see: http://www.tuxpaint.org/lists/).
Alternatively, if you have an account with SourceForge.net, you can
request to be added to the "tuxpaint" project and receive write-access
to the Git source code repository so that you may commit your changes
directly.
Note: Support for new locales requires making additions to Tux Paint's
source code ("/src/i18n.h" and "/src/i18n.c"), and requires updates to
the Makefile, to ensure the ".po" files are compiled into ".mo" files,
and available for use at runtime.
----------------------------------------------------------------------
Alternative Input Methods
Tux Paint's 'Text' and 'Label' tools can provide alternative input
methods for some languages. For example, when Tux Paint is running with
a Japanese locale, the right [Alt] key can be pressed to cycle between
Latin, Romanized Hiragana and Romanized Katakana modes. This allows
native characters and words to be entered into the 'Text' and 'Label'
tools by typing one or more keys on a keyboard with Latin characters
(e.g., a US QWERTY keyboard).
To create an input method for a new locale, create a text file with a
name based on the locale (e.g., "ja" for Japanese), with ".im" as the
extension (e.g., "ja.im").
The ".im" file can have multiple character mapping sections for
different character mapping modes. For example, on a Japanese typing
system, typing [K] [A] in Hiragana mode generates a different Unicode
character ("か") than typing [K] [A] in Katakana mode ("カ").
List the character mappings in this file, one per line. Each line should
contain (separated by whitespace):
* the Unicode value of the character, in hexadecimal (more than one
character can be listed, separated by a colon (':'), this allowing
some sequences to map to words)
* the keycode sequence (the ASCII characters that must be entered to
generate the Unicode character)
* a flag (or "-" if none)
Start additional character mapping sections with a line containign the
word "section".
Example:
# Hiragana
304B ka -
304C ga -
304D ki -
304E gi -
304D:3083 kya -
3063:305F tta -
# Katakana
section
30AB ka -
30AC ga -
30AD ki -
30AE gi -
Note: Blank lines within the ".im" file will be ignored, as will any
text following a "#" (pound/hash) character — it can be used to denote
comments, as seen in the example above.
Note: Meanings of the flags are locale-specific, and are processed by
the language-specific source code in "src/im.c". For example, "b" is
used in Korean to handle Batchim, which may carry over to the next
character.
Note: Support for new input methods requires making additions to Tux
Paint's source code ("/src/im.c"), and requires updates to the Makefile,
to ensure the ".im" files are available for use at runtime.
----------------------------------------------------------------------
On-screen Keyboard
As of version 0.9.22, Tux Paint's 'Text' and 'Label' tools can present
an on-screen keyboard that allows the pointer (via a mouse, eye-tracking
systems, etc.) to be used to input characters. Files that describe the
layout and available keys are stored in Tux Paint "osk" directory. Each
keyboard layout is defined by a number of files (some of which may be
shared by different layouts).
We'll use the QWERTY keyboard as an example:
Layout overview file ("qwerty.layout")
This is a text file that specifies the other files used to describe
the layout and key mappings.
layout qwerty.h_layout
keymap us-intl-altgr-dead-keys.keymap
composemap en_US.UTF-8_Compose

keyboardlist qwerty.layout default.layout
Note: Blank lines within the ".layout" file will be ignored, as will
any text following a "#" (pound/hash) character — it can be used to
denote comments, as seen in the example above.
The "keyboardlist" line describes which layouts to switch to, when the
user clicks the left and right buttons on the keyboard. (See below.)
Keyboard layout file ("qwerty.h_layout")
This describes how big the keyboard is (as a "width × height" grid),
and lists each key with its numeric keycode (see the "keymap" file,
below), the width it should be drawn at (typically "1.0", to take one
space on the keyboard, but in the example below, notice the "TAB" and
"SPACE" keys are much wider), the character or text to display on the
key, depending on which modifier keys have been pressed (one each for:
no modifiers, [Shift], [AltGr], and [Shift] + [AltGr]), and finally
whether or not the key is affected by the [CapsLock] key (use "1") or
[AltGr] (alternate graphics) key (use "2"), or not at all (use "0").

Notice here that alphabetic keys ([Q], [W], etc.) will be affected by
[CapsLock], while numeric keys ([1], [2], etc.), [Space], and so on,
will not.
Keycodes up to "8" are reserved for internal use. The ones currently
used are described below.
* 0 — empty button
* 1 — next layout (per the layout file's "keyboardlist" setting)
* 2 — previous layout (per the layout file's "keyboardlist" setting)
Keymap file ("us-intl-altgr-dead-keys.keymap")
This file defines which numeric keycodes (seen in the keyboard layout
files, such as "qwerty.h_layout" described above) should be mapped to
which actual characters that an application such as Tux Paint expects
to receive when keys (e.g., on a real keyboard) are pressed.
If you're using an operating system such as Linux, which runs X-Window
and has the "xmodmap" command-line tool available, you can run it with
the ("print keymap expressions" option, "-pke", to generate a keymap
file.

Composemap file ("en_US.UTF-8_Compose")
This file describes single characters that can be composed by multiple
inputs. For example, "[Compose]" followed by "[A]" and "[E]" can be
used to create the "æ" character.
The file that comes with Tux Paint is based on the US English UTF-8
(Unicode) composemap that comes with X.Org's X Window system. The
current version from the Xlib library has a web located page at
https://www.x.org/releases/current/doc/libX11/i18n/compose/en_US.UTF-8.html.
Keysym definitions file ("keysymdef.h")
This file (which is a C programming language header file) is also from
the X Window System. It defines the Unicode values of each keycap
(e.g., "XK_equal" corresponds to "U+003D", for the character "="
("EQUALS SIGN").
Note: This file is not compiled into Tux Paint, but is read and parsed
at runtime.
It is unlikely that any modification will be required of this file.
