<h2>How To Make PNGs</h2>
</header>
<p> <p>The following is a very <em>brief</em> list of ways to create PNGs or convert existing images into PNGs.

<dt>GIMP &amp; Krita</dt>
<dd>
<p>
Excellent tools with which to create PNG images for use in Tux Paint are GIMP and Krita, both high-quality Open Source interactive drawing and photo editing programs. </p>
<p> <p>
These features (openness, losslessness, compression, transparency/alpha) make it the best choice for Tux Paint. (Tux Paint's support for the PNG format comes from the Open Source SDL_Image library, which in turn gets it from the libPNG library.) </p> It is likely that one or both are already installed on your system. If not, they should be readily available from your Linux distribution's software repository. If not, or to learn more, visit <a href="http://www.gimp.org/">http://www.gimp.org/</a> and <a href="http://www.krita.org/">http://www.krita.org/</a>, respectively. </p>

<p> <dt>Command-line Tools</dt>
Support for many colors allows photo-quality "rubber stamp" images to be used in Tux Paint, and alpha transparency allows for high-quality brushes. </p> <dd>
