<h1>About</h1>
<blockquote>
<h2>What Is 'Tux Paint?'</h2>
<blockquote>
<p>Tux Paint is a free drawing program designed for young children
(kids ages 3 and up). It has a simple, easy-to-use interface, fun
sound effects, and an encouraging cartoon mascot who helps guide
children as they use the program. It provides a blank canvas and
a variety of drawing tools to help your child be creative.</p>
</blockquote>
<h2>License:</h2>
<blockquote>
<p>Tux Paint is an Open Source project, Free Software
released under the GNU General Public License (GPL). It is free, and
the 'source code' behind the program is available. (This allows
others to add features, fix bugs, and use parts of the program in their
own GPL'd software.)</p>
<p>See <a href="../COPYING.txt">COPYING.txt</a> for the full text of
the GPL license.</p>
</blockquote>
<h2>Objectives:</h2>
<blockquote>
<dl>
<dt><b>Easy and Fun</b></dt>
<dd>
Tux Paint is meant to be a simple drawing program for young children.
It is not meant as a general-purpose drawing tool. It <i>is</i> meant to
be fun and easy to use. Sound effects and a cartoon character help let
the user know what's going on, and keeps them entertained.
There are also extra-large cartoon-style mouse pointer shapes.
</dd>
<dt><b>Extensibility</b></dt>
<dd>
Tux Paint is extensible. Brushes and "rubber stamp" shapes can be
dropped in and pulled out. For example, a teacher can drop in a
collection of animal shapes and ask their students to draw an
ecosystem. Each shape can have a sound which is played, and
textual facts which are displayed, when the child selects the shape.
</dd>
<dt><b>Portability</b></dt>
<dd>
Tux Paint is portable among various computer platforms:
Windows, Macintosh, Linux, etc. The interface looks the same among
them all. Tux Paint runs suitably well on older systems (like a
Pentium 133), and can be built to run better on slow systems.
</dd>
<dt><b>Simplicity</b></dt>
<dd>
There is no direct access to the computer's underlying intricacies.
The current image is kept when the program quits, and reappears when
it is restarted. Saving images requires no need to create filenames
or use the keyboard. Opening an image is done by selecting it from
a collection of thumbnails. Access to other files on the computer is
restricted.
</dd>
</dl>

<h1>Using Tux Paint</h1>
<blockquote>
<h2>Loading Tux Paint</h2>
<blockquote>
<h3>Linux/Unix Users</h3>
<blockquote>
<p>Tux Paint should have placed a laucher icon in your KDE and/or GNOME
menus, under 'Graphics.'</p>
<p>Alternatively, you can run the following command at a shell prompt
(e.g., "$"):</p>
<blockquote>
<code>$ tuxpaint</code>
</blockquote>
<p>If any errors occur, they will be displayed on the terminal
(to "stderr").</p>
</blockquote>
<hr size=1 noshade>
<h3>Windows Users</h3>
<blockquote>
<table border=0 cellspacing=0 cellpadding=4 bgcolor="#AAAAFF"
align=right summary=""><tr><td align=center>
<img src="images/icon-win32.png" width=32 height=32 alt="[Icon]"><br>
Tux Paint
</td></tr></table>
<p>If you installed Tux Paint on your computer using the
'Tux Paint Installer,' it will have asked you whether you
wanted a 'Start' menu short-cut, and/or a desktop shortcut. If you
agreed, you can simply run Tux Paint from the 'Tux Paint'
section of your 'Start' menu (e.g., under "All Programs" on
Windows XP), or by double-clicking the "Tux Paint" icon
on your desktop.</p>
<p>If you installed Tux Paint using the 'ZIP-file' download,
or if you used the 'Tux Paint Installer,' but chose not to
have shortcuts installed, you'll need to double-click the
"<code>tuxpaint.exe</code>" icon in the 'Tux Paint' folder on
your computer.</p>
<p>By default, the 'Tux Paint Installer' will put
Tux Paint's folder in "<code>C:\Program Files\</code>",
though you may have changed this when the installer ran.</p>
<p>If you used the 'ZIP-file' download, Tux Paint's folder will
be wherever you put it when you unzipped the ZIP file.</p>
<br clear=all>
</blockquote>
<hr size=1 noshade>
<h3>Mac OS X Users</h3>
<blockquote>
Simply double-click the "Tux Paint" icon.<p>
</blockquote>
</blockquote>
<hr size=1 noshade>
<h2>Title Screen</h2>
<blockquote>
<p>When Tux Paint first loads, a title/credits screen will appear.</p>
<center><img src="images/tuxpaint-title.jpg" width=324 height=254
alt="[Title Screenshot]"></center>
<p>Once loading is complete, press a key or click on the mouse to continue.
(Or, after about 30 seconds, the title screen will go away
automatically.)</p>
</blockquote>
<hr size=1 noshade>
<h2>Main Screen</h2>
<blockquote>
The main screen is divided into the following sections:
<dl>
<dt>Left Side: Toolbar</dt>
<dd>
<p>The toolbar contains the drawing and editing controls.</p>
<center><img src="images/tools.jpg" width=324 height=254
alt="[Tools: Paint, Stamp, Lines, Shapes, Text, Magic, Undo, Redo,
Eraser, New, Open, Save, Print, Quit]"></center>
</dd>
<dt>Middle: Drawing Canvas</dt>
<dd>
<p>The largest part of the screen, in the center, is the drawing
canvas. This is, obviously, where you draw!</p>
<center><img src="images/canvas.jpg" width=324 height=254
alt="[(Canvas)]"></center>
</dd>
<dt>Right Side: Selector</dt>
<dd>
<p>Depending on the current tool, the selector shows different
things. e.g., when the Paint Brush tool is selected, it shows
the various brushes available. When the Rubber Stamp tool
is selected, it shows the different shapes you can use.</p>
<center><img src="images/selector.jpg" width=324 height=254
alt="[Selectors - Brushes, Letters, Shapes, Stamps]"></center>
</dd>
<dt>Lower: Colors</dt>
<dd>
<p>A palette of available colors are shown near the bottom of the
screen.</p>
<center><img src="images/colors.jpg" width=324 height=254
alt="[Colors - Black, White, Red, Pink, Orange, Yellow, Green, Cyan,
Blue, Purple, Brown, Grey]"></center>
</dd>
<dt>Bottom: Help Area</dt>
<dd>
<p>At the very bottom of the screen, Tux, the Linux Penguin,
provides tips and other information while you draw.</p>
<center><img src="images/tips.jpg" width=324 height=254
alt="(For example: 'Pick a shape. Click to pick the center, drag, then
let go when it is the size you want. Move around to rotate it, and
click to draw it.)"></center>

<h2>Available Tools</h2>
<blockquote>
<h3>Drawing Tools</h3>
<blockquote>
<dl>
<dt><b>Paint (Brush)</b></dt>
<dd>
<img src="images/tool_paint.png" width=48 height=48 alt="" align=right>
<p>The Paint Brush tool lets you draw freehand, using various
brushes (chosen in the Selector on the right) and colors
(chosen in the Color palette towards the bottom).</p>
<p>If you hold the mouse button down, and move the mouse, it will
draw as you move.</p>
<p>As you draw, a sound is played. The bigger the brush, the
lower the pitch.</p>
<br clear=all>
<center><img src="images/ex_paint.png" width=120 height=95
alt=""></center>
<hr size=1>
</dd>
<dt><b>Stamp (Rubber Stamp)</b></dt>
<dd>
<img src="images/tool_stamp.png" width=48 height=48 alt="" align=right>
<p>The Stamp tool is like a rubber stamp, or stickers. It lets you
paste pre-drawn or photographic images (like a picture of a horse,
or a tree, or the moon) in your picture.</p>
<p>As you move the mouse around, an outline follows the
mouse, showing where the stamp will be placed.</p>
<p>Different stamps can have different sound effects.
Some stamps can be colored or tinted.</p>
<p>Stamps can be shrunk and expanded, and many stamps can be
flipped vertically, or displayed as a mirror-image, using
controls at the bottom right of the screen.</p>
<p>(NOTE: If the "<code>nostampcontrols</code>" option is set,
Tux Paint won't display the Mirror, Flip, Shrink and Grow
controls for stamps.
See the "<a href="OPTIONS.html"><i>Options</i></a>"
documentation.)</p>
<br clear=all>
<center><img src="images/ex_stamps.png" width=182 height=156

<hr size=1>
</dd>
<dt><b>Lines</b></dt>
<dd>
<img src="images/tool_lines.png" width=48 height=48 alt="" align=right>
<p>This tool lets you draw straight lines using the various
brushes and colors you normally use with the Paint Brush.</p>
<p>Click the mouse and hold it to choose the starting point of the
line. As you move the mouse around, a thin 'rubber-band' line
will show where the line will be drawn.</p>
<p>Let go of the mouse to complete the line. A "sproing!" sound will
play.</p>
<br clear=all>
<center><img src="images/ex_lines.png" width=76 height=103
alt=""></center>
<hr size=1>
</dd>
<dt><b>Shapes</b></dt>
<dd>
<img src="images/tool_shapes.png" width=48 height=48 alt=""
align=right>
<p>This tool lets you draw some simple filled, and un-filled shapes.</p>
<p>Select a shape from the selector on the right (circle, square,
oval, etc.).</p>
<p>In the canvas, click the mouse and hold it to stretch the shape
out from where you clicked. Some shapes can change proportion
(e.g., rectangle and oval), others cannot (e.g., square and circle).</p>
<p>Let go of the mouse when you're done stretching.</p>
<dl>
<dt>Normal Mode</dt>
<dd>
<p>Now you can move the mouse around the canvas to rotate the
shape.</p>
<p>Click the mouse button again and the shape will be drawn in the
current color.</p>
</dd>
<dt>Simple Shapes Mode</dt>
<dd>
If simple shapes are enabled (e.g., with the
"<code>--simpleshapes</code>" option),
the shape will be drawn on the canvas when you let go of the
mouse button. (There's no rotation step.)
</dd>
</dl>
<br clear=all>
<center><img src="images/ex_shapes.png" width=177 height=104
alt=""></center>
<hr size=1>
</dd>
<dt><b>Text</b></dt>
<dd>
<img src="images/tool_text.png" width=48 height=48 alt="" align=right>
<p>Choose a font (from the 'Letters' available on the right) and a color
(from the color palette near the bottom). Click on the screen and a
cursor will appear. Type text and it will show up on the screen.</p>
<p>Press <b>[Enter]</b> or <b>[Return]</b> and the text will be drawn
onto the picture and the cursor will move down one line.</p>
<p>Click elsewhere in the picture and the current line of text will
move there, where you can continue editing.</p>
<br clear=all>
<center><img src="images/ex_text.png" width=139 height=69

<hr size=1>
</dd>
<dt><b>Magic (Special Effects)</b></dt>
<dd>
<img src="images/tool_magic.png" width=48 height=48 alt="" align=right>
<p>The 'Magic' tool is actually a set of special tools. Select one of
the "magic" effects from the selector on the right, and then
click and drag around the picture to apply the effect.</p>
<br clear=all>
<dl>
<dt><b>Rainbow</b></dt>
<dd>
This is similar to the paint brush, but as you move the mouse
around, it goes through all of the colors in the rainbow.
</dd>
<dt><b>Sparkles</b></dt>
<dd>
This draws glowing yellow sparkles on the picture.
</dd>
<dt><b>Mirror</b></dt>
<dd>
When you click the mouse in your picture with the "Mirror"
magic effect selected, the entire image will be reversed,
turning it into a mirror image.
</dd>
<dt><b>Flip</b></dt>
<dd>
Similar to "Mirror." Click and the entire image will be turned
upside-down.
</dd>
<dt><b>Blur</b></dt>
<dd>
This makes the picture fuzzy wherever you drag the mouse.
</dd>
<dt><b>Smudge</b></dt>
<dd>
This pushes the colors around under the mouse, like finger painting
with wet paint.
</dd>
<dt><b>Fade</b></dt>
<dd>
This fades the colors wherever you drag the mouse.
(Do it to the same spot many times, and it will eventually become
white.)
</dd>
<dt><b>Darken</b></dt>
<dd>
This dakrens the colors wherever you drag the mouse.
(Do it to the same spot many times, and it will eventually become
black.)
</dd>
<dt><b>Chalk</b></dt>
<dd>
This makes parts of the picture (where you move the mouse)
look like a chalk drawing.
</dd>
<dt><b>Blocks</b></dt>
<dd>
This makes the picture blocky looking ("pixelated") wherever
you drag the mouse.
</dd>
<dt><b>Thick</b></dt>
<dd>
This makes the darker colors in the picture become thicker
wherever you drag the mouse.
</dd>
<dt><b>Thin</b></dt>
<dd>
Similar to "Thick," except dark colors become thinner
(light colors become thicker).
</dd>
<dt><b>Negative</b></dt>
<dd>
This inverts the colors wherever you drag the mouse.
(e.g., white becomes black, and vice versa.)
</dd>
<dt><b>Tint</b></dt>
<dd>
This changes the parts of the picture to the selected color.
</dd>
<dt><b>Drip</b></dt>
<dd>
This makes the paint "drip" wherever you move the mouse.
</dd>
<dt><b>Cartoon</b></dt>
<dd>
This makes the picture look like a cartoon — with thick
outlines and solid colors — wherever you move the mouse.
</dd>
<dt><b>Fill</b></dt>
<dd>
This floods the picture with a color. It lets you quickly
fill parts of the picture, as if it were a coloring book.
</dd>
</dl>
<hr size=1>
</dd>
<dt><b>Eraser</b></dt>
<dd>
<img src="images/tool_eraser.png" width=48 height=48 alt=""
align=right>
<p>This tool is similar to the Paint Brush. Wherever you click
(or click and drag), the picture will be erased either to white,
or to the background picture, if you began the current drawing
with a 'Starter' image.</p>
<p>A number of eraser sizes are available.</p>
<p>As you move the mouse around, a square outline follows
the pointer, showing what part of the picture will be erased to
white.</p>
<p>As you erase, a "squeaky clean" eraser/wiping sound is played.</p>

</ul>
</blockquote>
<b>'Starter' Images</b>
<blockquote>
<p>Along with pictures you've created, Tux Paint can provided
'Starter' images. Opening them is like creating a new picture,
except that the picture isn't blank. 'Starters' can be like a page
from a coloring book (a black-and-white outline of a picture, which
you can then color in), or like a 3D photograph, where you draw
the bits in between.</p>
<p>'Starter' images have a green background in the 'Open' screen.
(Normal images have a blue background.) When you load a 'Starter,'
draw on it, and then click 'Save,' it creates a new picture
(it doesn't overwrite the original 'Starter,' so you can use it
again later).</p>
</blockquote>
<p>If choose to open a picture, and your current drawing hasn't been
saved, you will be prompted as to whether you want to save it or not.
(See "<a href="#save">Save</a>," below.)</p>

the list of saved images. (i.e., it will create a new file)</p>
<p>Note: It won't ask you anything (e.g., for a filename).
It will simply save the picture, and play a "camera shutter" sound
effect.</p>

<h1>Loading Other Pictures into Tux Paint</h1>
<blockquote>
<p>Since Tux Paint's 'Open' dialog only displays pictures you created
with Tux Paint, what if you want to load some other picture or
photograph into Tux Paint to edit?</p>
<p>To do so, you simply need to convert the picture into
a PNG (Portable Network Graphic) image file, and place it in Tux Paint's
"saved" directory. ("<code>~/.tuxpaint/saved/</code>" under Linux and Unix,
"<code>userdata\saved\</code>" under Windows,
"<code>Library/Preferences/tuxpaint/saved/</code>" under Mac OS X.)
</p>
<h2>Using '<code>tuxpaint-import</code>'</h2>
<blockquote>
<p>Linux and Unix users can use the "<code><b>tuxpaint-import</b></code>"
shell script which gets installed when you install Tux Paint.
It uses some NetPBM tools to convert the image ("<code>anytopnm</code>"),
resize it so that it will fit in Tux Paint's canvas
("<code>pnmscale</code>"), and convert it to a PNG
("<code>pnmtopng</code>").</p>
<p>It also uses the "<code>date</code>" command to get the current time and
date, which is the file-naming convention Tux Paint uses for saved
files. (Remember, you are never asked for a 'filename' when you go to
Save or Open pictures!)</p>
<p>To use '<code>tuxpaint-import</code>', simply run the command from a
command-line prompt and provide it the name(s) of the file(s) you wish
to convert.</p>
<p>They will be converted and placed in your Tux Paint 'saved'
directory. (Note: If you're doing this for a different user - e.g.,
your child, you'll need to make sure to run the command under their
account.)</p>
<p>Example:</p>
<blockquote><code>
$ <b>tuxpaint-import grandma.jpg</b><br>
grandma.jpg -> /home/username/.tuxpaint/saved/20020921123456.png<br>
jpegtopnm: WRITING A PPM FILE
</code></blockquote>
<p>The first line ("<code>tuxpaint-import grandma.jpg</code>") is the
command to run. The following two lines are output from the program while
it's working.</p>
<p>Now you can load Tux Paint, and a version of that original picture
will be available under the 'Open' dialog. Just double-click its icon!</p>
</blockquote>
<h2>Doing it Manually</h2>
<blockquote>
<p>Windows, Mac OS X and BeOS users must currently do the conversion
manually.</p>
<p>Load a graphics program that is capable of both loading your picture
and saving a PNG format file. (See the documentation file "PNG.txt"
for a list of suggested software, and other references.)</p>
<p>Reduce the size of the image to no wider than 448 pixels across and
no taller than 376 pixels tall. (i.e., the maximum size
is 448 x 376 pixels)</p>
<p>Save the picture in PNG format. It is <b>highly</b> recommended that you
name the filename using the current date and time, since that's
the convention Tux Paint uses:</p>
<blockquote>
<code><b>YYYYMMDDhhmmss</b>.png</code>
</blockquote>
<ul>
<li>YYYY = Year
<li>MM = Month (01-12)
<li>DD = Day (01-31)
<li>HH = Hour, in 24-hour format (00-23)
<li>mm = Minute (00-59)
<li>ss = Second (00-59)
</ul>
<p>e.g.:</p>
<blockquote>
<code>20020921130500</code> - for September 21, 2002, 1:05:00pm
</blockquote>
<p>Place this PNG file in your Tux Paint '<code>saved</code>'
directory. (See above.)</p>
<p>Under Windows, this is in the "<code>userdata</code>" folder.
Under Mac OS X, this is in "<code>Library/Preferences/tuxpaint/</code>"
in your home directory.</p>

<h1>Extending Tux Paint</h1>
<blockquote>
<p>If you wish to add or change things like Brushes and Rubber Stamps
used by Tux Paint, you can do it fairly easily by simply putting
or removing files on your hard disk.</p>
<p>Note: You'll need to restart Tux Paint for the changes to take
effect.</p>
<h2>Where Files Go</h2>
<blockquote>
<h3>Standard Files</h3>
<blockquote>
<p>Tux Paint looks for its various data files in its
'data' directory.</p>
<h4>Linux and Unix</h4>
<blockquote>
<p>Where this directory goes depends on what value was set for
"<code>DATA_PREFIX</code>" when Tux Paint was built. See
INSTALL.txt for details.</p>
<p>By default, though, the directory is:</p>
<blockquote><code>
/usr/local/share/tuxpaint/
</code></blockquote>
<p>If you installed from a package, it is more likely to be:</p>
<blockquote><code>
/usr/share/tuxpaint/
</code></blockquote>
</blockquote>
<h4>Windows</h4>
<blockquote>
<p>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.:</p>
<blockquote><code>
C:\Program Files\TuxPaint\data
</code></blockquote>
</blockquote>
<h4>Mac OS X</h4>
<blockquote>
<p>Tux Paint stores files in your account's
"Libraries" folder, under "Preferences", e.g.:</p>
<blockquote><code>
/Users/Joe/Library/Preferences/
</code></blockquote>
</blockquote>
</blockquote>
<hr size=1 noshade>
<h3>Personal Files</h3>
<blockquote>
<p>You can also create brushes, stamps, fonts and 'starters' in your
own directory for Tux Paint to find.</p>
<h4>Linux and Unix</h4>
<blockquote>
<p>Your personal Tux Paint directory is
"<code>~/.tuxpaint/</code>".</p>
<p>That is, if your home directory is "<code>/home/karl</code>", then
your Tux Paint directory is
"<code>/home/karl/.tuxpaint/</code>".</p>
<p>Don't forget the period ("<code>.</code>") before the
'<code>tuxpaint</code>'!</p>
</blockquote>
<h4>Windows</h4>
<blockquote>
<p>Your personal Tux Paint directory is named "userdata" and
is in the same directory as the executable e.g.:</p>
<blockquote><code>
C:\Program Files\TuxPaint\userdata
</code></blockquote>
</blockquote>
<p>To add brushes, stamps fonts, and 'starters,' create subdirectories
under your personal Tux Paint directory named
"<code><b>brushes</b></code>", "<code><b>stamps</b></code>",
"<code><b>fonts</b></code>" and
"<code><b>starters</b></code>" respectively.</p>
<p>(For example, if you created a brush named "<code>flower.png</code>",
you would put it in "<code>~/.tuxpaint/brushes/</code>" under Linux or
Unix.)</p>
</blockquote>
</blockquote>
<hr size=1 noshade>
<h2>Brushes</h2>
<blockquote>
<p>The brushes used for drawing with the 'Brush' and 'Lines' tools in
Tux Paint are simply greyscale PNG images.</p>
<img src="images/brush_edit.png" width=123 height=147 alt="" align=right>
<p>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!</p>
<p>Brush images should be no wider than 40 pixels across and
no taller than 40 pixels high. (i.e., the maximum size
can be 40 x 40.)</p>
<p>Just place them in the "<code><b>brushes</b></code>" directory.</p>
<p>Note: If your new brushes all come out as solid squares or rectangles,
it's because you forgot to use alpha transparency! See the documentation
file "PNG.txt" for more information and tips.</p>
<br clear=all>
</blockquote>
<hr size=1 noshade>
<h2>Stamps</h2>
<blockquote>
<p>All stamp-related files go in the "<code><b>stamps</b></code>" directory.
It's useful to create subdirectories and sub-subdirectories
there to organize the stamps. (For example, you can have a
"<code>holidays</code>" folder with "<code>halloween</code>" and
"<code>christmas</code>" sub-folders.)</p>
<h3>Images</h3>
<blockquote>
<p>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.</p>
<img src="images/stamp_edit.png" width=128 height=147 alt="" align=right>
<p>The Stamps used by Tux Paint are PNG pictures. They can be
full-color or greyscale. The alpha (transparency) of the PNG is
used to determine the actual shape of the picture (otherwise you'll
stamp a large rectangle on your drawings).</p>
<p>The PNGs can be any size, but in practice, a 100 pixels wide by
100 pixels tall (100 x 100) is quite large for
Tux Paint.</p>
<p>Note: If your new stamps all have solid rectangular-shaped outlines
of a solid color (e.g., white or black), it's because you forgot to use
alpha transparency! See the documentation file "PNG.txt" for more
information and tips.</p>
<br clear=all>
</blockquote>
<hr size=1 noshade>
<h3>Description Text</h3>
<blockquote>
<p>Text (".TXT") files with the same name as the PNG.
(e.g., "<code>picture.png</code>"'s description is stored in
"<code>picture.txt</code>" in the same directory.)</p>
<p>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.</p>
<h4>Language Support</h4>
<blockquote>
<p>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).</p>
<p>The beginning of the line should correspond to the language code
of the language in question (e.g., "<code>fr</code>" for French, and
"<code>zh_tw</code>" for Traditional Chinese), followed by
"<code>.utf8=</code>" and the translated description (encoded
in UTF-8).</p>
<p>There are scripts in the "<code>po</code>" 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.</p>
<p>If no translation is available for the language Tux Paint
is currently running in, the US English text is used.</p>
</blockquote>
<h4>Windows Users</h4>
<blockquote>
<p>Use NotePad or WordPad to edit/create these files.
Be sure to save them as Plain Text, and make sure they have
"<code>.txt</code>" at the end of the filename...</p>
</blockquote>
</blockquote>
<hr size=1 noshade>
<h3>Sound Effects</h3>
<blockquote>
<p>WAVE (".WAV") files with the same name as the PNG.
(e.g., "<code>picture.png</code>"'s sound effect is the sound
"<code>picture.wav</code>" in the same directory.)</p>
<h4>Language Support</h4>
<blockquote>
<p>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 files with the locale's label in the filename, in
the form: "<code><b>STAMP_LOCALE</b>.wav</code>"</p>
<p>"<code>picture.png</code>"'s sound effect, when Tux Paint is run
in Spanish mode, would be "<code>picture_es.wav</code>".
In French mode, "<code>picture_fr.wav</code>". And so on...</p>
<p>If no localized sound effect can be loaded, Tux Paint will
attempt to load the 'default' sound file.
(e.g., "<code>picture.wav</code>")</p>
</blockquote>
</blockquote>
<hr size=1 noshade>
<h3>Stamp Options</h3>
<blockquote>
<p>Aside from a graphical shape, a textual description, and a sound
effect, stamps can also be given other attributes. To do this, you need
to create a 'data file' for the stamp.</p>
<p>A stamp data file is simply a text file containing the options.</p>
<p>The file has the same name as the PNG image, but a "<code>.dat</code>"
extension. (e.g., "<code>picture.png</code>"'s data file is the text
file "<code>picture.dat</code>" in the same directory.)</p>
<h4>Colored Stamps</h4>
<blockquote>
<p>Stamps can be made to be either "colorable" or "tintable."</p>
<h5>Colorable</h5>
<blockquote>
<p>"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.)</p>
<p>Nothing about the original image is used except the transparency
("alpha" channel). The color of the stamp comes out solid.</p>
<center><img src="images/ex_colorable.png" width=74 height=92
alt=""></center>
<p>Add the word "<code><b>colorable</b></code>" to the stamp's data
file.</p>
</blockquote>
<h5>Tinted</h5>
<blockquote>
<p>"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.)</p>
<center><img src="images/ex_tintable.png" width=151 height=78
alt=""></center>
<p>Add the word "<code><b>tintable</b></code>" to the stamp's data
file.</p>
<p>Sometimes you don't want the white or gray parts of an image
tinted (see for example the dry erase marker stamp in the default
stamp package). You can add the word "<code><b>notintgray</b></code>"
to the stamp's data file to accomplish this. Only areas with saturation
over 25 % are then tinted.</p>
</blockquote>
</blockquote>
<h4>Unalterable Stamps</h4>
<blockquote>
<p>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.</p>
<p>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.</p>
<p>To make a stamp un-flippable, add the option
"<code><b>noflip</b></code>" to the stamp's data file.</p>
<p>To keep a stamp from being mirrored, add the option
"<code><b>nomirror</b></code>" to the stamp's data file.</p>
</blockquote>
<h4>Initial Stamp Size</h4>
<blockquote>
<p>By default, Tux Paint assumes that your stamp is sized
appropriately for unscaled display on a 608x472 canvas. This is
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.</p>
<p>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 the option "<code><b>scale 40%</b></code>" or
"<code><b>scale 5/2</b></code>" or "<code><b>scale 2.5</b></code>"
or "<code><b>scale 2:5</b></code>" to your image. You may include
an "<code><b>=</b></code>" if you wish, as in
"<code><b>scale=40%</b></code>".</p>
</blockquote>
<h4>Windows Users</h4>
<blockquote>
<p>You can use NotePad or WordPad to create these file.
Be sure to save it as Plain Text, and make sure the filename
has "<code>.dat</code>" at the end, and not "<code>.txt</code>"...</p>
</blockquote>
</blockquote>
<h3>Pre-Mirrored Images</h3>
<blockquote>
<p>In some cases, you may wish to provide a pre-drawn version of
a stamp's mirror-image. For example, imagine a picture of a fire
truck with the words "<i>Fire Department</i>" written across
the side. You probably do not want that text to appear backwards
when the image is flipped!</p>
<p>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
"<code>.png</code>" graphics file with the same name, except with
the string "<code><b>_mirror</b></code>" before the filename
extension.</p>
<p>For example, for the stamp "<code><b>truck.png</b></code>" you would
create another file named "<code><b>truck_mirror.png</b></code>", which
will be used when the stamp is mirrored (rather than using a
backwards version of '<code>truck.png</code>').</p>
</blockquote>
</blockquote>

<h2>Fonts</h2>
<blockquote>
<img src="images/fontsizes.png" width=48 height=48 alt="" align=right>
<p>The fonts used by Tux Paint are TrueType Fonts (TTF).</p>
<p>Simply place them in the "<code><b>fonts</b></code>" directory.
Tux Paint will load the font and provide four different sizes
in the 'Letters' selector when using the 'Text' tool.</p>
<br clear=all>
</blockquote>
<hr size=1 noshade>
<h2>'Starters'</h2>
<blockquote>
<img src="images/open_open.png" width=48 height=48 alt="" align=right>
<p>'Starter' images appear in the 'Open' dialog, along with pictures
you've created. They have a green button background, instead of blue.</p>
<p>Unlike your saved pictures, however, when you select and open a
'starter,' you're actually creating a new drawing. Instead of being
blank, though, the new drawing contains the contents of the 'starter.'
Additionally, as you edit your new picture, the contents of the
original 'starter' affect it.</p>
<b>Coloring-Book Style</b>
<blockquote>
<p>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.</p>
<p>To create this kind of 'starter' image, simply draw an outlined
picture in a paint program, make the rest of the graphic transparent
(that will come out as white in Tux Paint), and save it as a
PNG format file.</p>
</blockquote>
<b>Scene-Style</b>
<blockquote>
<p>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!</p>
<p>When the 'Eraser' tool is used on a picture based on this kind of
'starter' image, rather than turning the canvas white, it returns that
part of the canvas to the original background picture.</p>
<p>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.</p>
<p>To create this kind of 'starter' picture, simply create an overlay
(with alpha transparency) as described above, and save it as a PNG.
Then create another image (without transparency), and save it with
the same filename, but with "<code>-back</code>" appended to the
name. (e.g., "<code>reef-back.png</code>" would be the background
ocean picture that corresponds to the "<code>reef.png</code>"
overlay, or foreground.)</p>
</blockquote>
<p>The 'starter' images should be the same size as Tux Paint's
canvas. In the default 640x480 mode, that is 448x376 pixels.
If you're using 800x600 mode, it should be 608x496. (It should be
192 pixels less wide, and 104 pixels less tall than the resolution.)</p>
<p>Place them in the "<code><b>starters</b></code>" directory.
When the 'Open' dialog is accessed in Tux Paint, the 'starter'
images will appear at the beginning of the list with a green background.</p>
<p><b>Note:</b> 'Starters' can't be saved over from within Tux Paint,
since loading a 'starter' is really like creating a new image.
(Instead of being blank, though there's already something there to work
with.) The 'Save' command simply creates a new picture, like it would
if the 'New' command had been used.</p>
<p><b>Note:</b> 'Starters' are 'attached' to saved pictures, via a
small text file that has the same name as the saved file, but with
"<code>.dat</code>" as the extension. This allows the overlay and
background, if any, to continue to affect the drawing even after
Tux Paint has been quit, or another picture loaded or started.
(In other words, if you base a drawing on a 'starter' image, it will
always be affected by it.)</p>
