|
||
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.
