I think i have a vector image format, how do use it to draw an image in php?

I have found an image format that is being used by some applets. but i don't know what it is. I think it is some kind of vector graphics format that is used by the GD library.

could someone help me decode it?

I would like to use the raw data to produce a png, in php

the data is being generated from squiggles drawn by the mouse.

Is there some neato GD library function that I can feed the data into to recreate the image? (looking for a PHP libray function to do the job.) an example of the output from the form is below

Those look like X-Y coordinates. Just do a MoveTo on the first pair, then LineTo on the subsequent pairs.
