Hi!
I would like to create a custom button control with partially transparent pictures as normal and mouse over state. I want the user to be able to set the pictures himself and also be able to adjust the tiling/stretch/offset. Now I need to figure out some way to trigger e.g. the mousemove event, but not on the transparent areas.
I was thinking about using imagecache, getting the bitmap from there and checking for the color on pixel but it's not very efficient on mousemove.
Is there possibly a better solution?
