image mapping sections of a ring?

[starmatt]

I posted this in the graphic design forum and was told it probably belongs here:

I should preface this question with the note that I currently have a working solution, but I would prefer a more elegant solution: I am a bit of a perfectionist.

I have an image that has two concentric circles. The inside circle is a link, but the outer ring is split into four sections that need to be four separate links. If you are having trouble visualizing, here is the image in question:



The current solution is to define 4 squares behind the inner circle for those links, but I would prefer to have the links stop at the arc of the outer circle (rather than going out to the corners of the image). Is there any way to do that aside from approximating the arc with a polygon with a million corners?

Hey

neat chart.



What about using a polygon image map. I think you specify the shape as a polygon and then when you enter the coordinates for the map, every number you enter represents a point on the shape...that way you could 'turn' it with the curves of the diagram....the whole thing wont be mapped cause your using straight sides but you could get a general 'curve' in there.
