I'm having some trouble with the PictureMarkerSymbol using a Bitmap and am seeking suggestions. I'm dynamically generating Bitmaps and tossing them into a PictureMarkerSymbol and my problem is that each symbol will only display once. So for example if I have five points with five different symbols they all show up. But if I have ten points all the same symbol only one point appears.
But I can't figure out why BitmapSymbol works and PictureMarkerSymbol doesn't. Why does overriding the clear() and draw() methods magically fix it? Does anyone have any ideas?
