If you are in a
hurry to get a fix that may already be available in the development branch you can
always try the latest nightly build available from the JpGraph home page. However be
aware that a nightly build could be broken on rare occasions. However, our
development philosophy is to always have a releasable repository so for the most of
the time the snapshot will work fine. The snapshot is available from:</p><p><code class="uri"><a class="uri" href="http://www.aditus.nu/jpgraph/jpsnapshot.php" target="_top">http://www.aditus.nu/jpgraph/jpsnapshot.php</a></code></p><p>The following is a partial list of what we believe to be the most irritating known
bugs (and omissions). See the <code class="uri"><a class="uri" href="http://www.aditus.nu/bugtraq/index.php" target="_top">Bugtracker</a></code> for a more
current view on additional known minor issues with the library.</p><div class="orderedlist"><ol type="1"><li><p>For performance reasons background images are not rotated along with
graphs in rotated graphs. Images rotation must be made outside the
library with some image manipulation program. This will never be
included as a feature of the library since PHP is simply to slow for
this kind of pixel-by-pixel image manipulation.</p></li><li><p>The library does not work with a 64bit OS (This is partly due to PHP
and partly due to some calculation of Error codes that assumes 32 bit
integers)</p></li><li><p>Truetype fonts are aligned according to there bounding box. This means
that text line that contain characters below the baseline (e.g. "j")
will be aligned slightly different from texts that only contain
characters that are above the baseline (e.g. "a").</p></li></ol></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch01s10.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="ch01.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="ch02.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">1.10. Where to find additional information </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 2. The Short Version: Installing the library (for PHP/Apache experts)</td></tr></table></div></body></html>
