Thread:Extension talk:ImageMap/Imagemap Area highlight script/reply (23)

this tool uses a feature that was non-standard for a long time, but supported by most browsers and eventually made its way to html5, which is called "canvas".

microsoft had similar functionality for IE, but it uses different semantics. there is a tool (i.e., a javascript library) made public by google that emulates "canvas" functionality and under the hood translate it to the explorer semantics. i was not able to make this tool work with my script (or rather, i was not able to make my script work with this tool), but i have strong suspicion that it's possible. the tool is called "explorercanvas" or "excanvas". this is the "project home" for excanvas on google:

luckily, html5 becomes more and more of a standard, and explorer 9 and 10 now support the standard "canvas", and hence my script.

if anyone wants to take a shot at teaching this script to work with excanvas i will be very grateful.

peace.
