hi, i've been tinkering with this, finally got it working--still some bugs:<br>
<br>
javascript for polyline class at:<br>
<a href="http://128.32.253.220/draw/polyline.js">http://128.32.253.220/draw/polyline.js</a><br>
perl GD script at:<br>
<a href="http://128.32.253.220/draw/polyline.pl.txt">http://128.32.253.220/draw/polyline.pl.txt</a><br>
example at:<br>
<a href="http://128.32.253.220/kamapdev/htdocs/index2.html">http://128.32.253.220/kamapdev/htdocs/index2.html</a><br>
<br>
i have drawn polylines with 16,000+ pts and it works fine. there seems
to be no problem even if the images are fairly large--though things get
a little slower, it is probably better to use w. zorn's library for
extremely large polylines. or at least break up the image....<br>
<br>
also, as it is now, all points are stored in the polyline object.
there's a better way to do it but it involves more accounting and i
haven't got around to that yet. <br>
