hi, i've been tinkering with this, finally got it working--still some bugs:

javascript for polyline class at:
perl GD script at:
example at:

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....

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.
