PNG image with transparent background mouse-over problem

**JediX** · 20 January 2011, 12:59 AM

Hi,

I have 4 pictures of characters that I want to use as buttons that get larger as you roll over them, like in the mouse -over tutorial. I have followed the tutorial and I have got the mouse-over working. The problem I am facing is that the images I am using are .png with transparent backgrounds and they are all overlapping each other slightly. When I go to roll-over the middle images the outer image enlarges. What is happening is that the transparent background for each image is being selected with the rest of the picture when being rolled-over. So instead of just selecting the the cutout image it is selecting the whole picturebox. Is there a way for the roll-over to not pick up the transparent background?

Answer: No.

Transparent or not, it's still pixels and all bitmaps are rectangles. Only way is to use polygon image maps, but - xara can't do this.

Actually you can, by using a workaround that I mention here: http://www.talkgraphics.com/showthre...429#post312429
