<h2>Brushes</h2>
<blockquote>
<p>The brushes used for drawing with the 'Brush' and 'Lines' tools in
Tux&nbsp;Paint are simply greyscale PNG images.</p>

of the brush, which means that the shape can be 'anti-aliased' and even
partially-transparent!</p>
<p>Greyscale pixels in the brush PNG will be drawn using the
currently-selected color in Tux&nbsp;Paint. Color pixels will be
tinted.</p>
<p>Brush images should be no wider than 40&nbsp;pixels across and
no taller than 40&nbsp;pixels high. (i.e., the maximum size
can be 40&nbsp;x&nbsp;40.)</p>
<p>Just place them in the "<code><b>brushes</b></code>" directory.</p>
<h3>Brush Options</h3>
<blockquote>
<p>Aside from a graphical shape, brushes can also be given other
attributes. To do this, you need to create a 'data&nbsp;file'
for the brush.</p>
<p>A brush 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>brush.png</code>"'s data file is the text
file "<code>brush.dat</code>" in the same directory.)</p>
<h4>Animated Brushes</h4>
<blockquote>
<p>As of Tux&nbsp;Paint version 0.9.16, you may now create animated
brushes. As the brush is drawn, each frame of the animation is
displayed.</p>
<p>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.</p>
<p>Add a line containing the line "<code><b>frames=<i>N</i></b></code>"
to the brush's data file, where <i>N</i> is the number of frames
in the brush.</p>
</blockquote>
</blockquote>
<p>Place the brush image PNGs (and any data text files) 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
