Hi,

Is it possible to get at the imageMap of a <ice:graphicImage>?

I'm trying to modify WebMC to allow users to draw primitive graphics on the image then submit the drawing for all users to see.

I have the drawing part working OK with a simple JavaScript drawing routine.

Now I'd like to be able to get at the bitmap so I can overlay the drawing on the slide for the other users to see. I can do this easily with Java2D.

I guess it would be best to do that within WebMC by modifying the routine that delivers the image to the renderer.

Where is that?

I guess I could also write a new tag based on <ice:graphicImage> that accepts attributes for drawing a graphic primitive on top of the image.

I Imagine I'd have to add an entry to the TLD and recompile.

Is that practical?

That would actually be kind of nice because I could use all of the standard techniques to update the bean and redraw the image.

Thanks,

Rick
