<h3><a name="libpng">Where can I get libpng?</a></h3>
<p>
Libpng is available at:<blockquote><a href="http://www.cdrom.com/pub/png/pngcode.html">http://www.cdrom.com/pub/png/pngcode.html</a></blockquote>
</p>
<h3><a name="giflib">Where can I get giflib/libungif?</a></h3>
<p>
Libungif is identical to Giflib except that it does not include
the questionable LZW compression that Unisys owns the rights to.
Images generated with Libungif will be uncompressed (larger).
Libungif 4.X is available at:
</p>
<blockquote><a href="http://prtr-13.ucsc.edu/~badger/software/libungif.shtml">http://prtr-13.ucsc.edu/~badger/software/libungif.shtml</a></blockquote>
<p>
Giflib 4.X is available at:
</p>
<blockquote><a href="http://prtr-13.ucsc.edu/~badger/software/giflib.shtml">http://prtr-13.ucsc.edu/~badger/software/giflib.shtml</a></blockquote>
<h3><a name="msdev">Can I build Ilib with MS Visual Developer Studio?</a></h3>
<p>
Yes, it has been successfully built using MS Developer Studio on Windows
NT. You must setup your own project for this.
</p>
<h3><a name="cygnus">Can I build Ilib with Cygnus' Win32 GCC?</a></h3>
<p>
Yes, you can. However, you will also have to use GCC to build
your application and you will need to distribute the required
Cygnus runtime DLLs with it.
</p>
<h3><a name="x11err">I get a bunch of X11-related link errors. What's that all about?</a></h3>
<p>
Version 4.X of Giflib/Libungif requires you to add -lX11 to LIBS and all
the makefiles. (Version 3.X did not require this.)
You can get around this by building Giflib/Libungif without support
for X11. (Try <tt>configure --help</tt> when building
Giflib/Libungif for information on how to do this.)
</p>
<h3><a name="ifont2h">What's the purpose of the <tt>ifont2h</tt> utility?</a></h3>
<p>
The <tt>ifont2h</tt> utility allow you to embed a font within the
application's executable so that you do not need to distribute the
BDF font file with the executable.
</p>
<h3><a name="patches">Do you accept patches/modifications?</a></h3>
<p>
You bet... Just email any patches to <a href="mailto:cknudsen@cknudsen.com">cknudsen@cknudsen.com</a>.
</p>
<h3><a name="todo">What are some of the features that can be added?</a></h3>
<ul>
<li>Add new drawing functions:
<ul>
<li><tt>IFillArc()</tt></li>
</ul>
<li>Better routines for converting 24-bit images to 8-bit images.</li>
<li>Add support for True Type (scalable) fonts -- this will allow
text to be drawn at angles</li>
<li>Add support for more file types:
<ul>
<li>Update PNG to use 8-bit (colormapped) for writing when possible </li>
<li>Read XPM </li>
<li>Read/Write XBM </li>
<li>Read/Write PAM </li>
<li>Write BMP </li>
<li>Write PostScript </li>
</ul></li>
<li>Any other useful clients that could be packaged with Ilib
(squid traffic reporter generator, etc.)</li>
<li>Provide makefiles for Win32</li>
<li>Autoconf for makefiles
<li>A perl module for Ilib</li>
<li>A PHP module for Ilib</li>
</ul>
