Hi! I need to create a panel of icons that can be dragged and dropped onto a map layer.
Help! What types of image files can be used? I am happy I can create the view with a tree of icons to drag and drop. I can probably figure out how to do the drag and drop code. I have no idea how to add an icon to a map layer The email below seemed to hint at possibly something similar to what I need to be able to do. Could I have a little more information / pointers about creating jpg layers.

I'm using the WorldImageExtension to construct jpeg layers. Sometimes, the layers show up just fine. Other times, the exact same files will not render. Digging down deeper, it turns out that an IllegalArgumentException is thrown. It's actually inside the geotools WorldImageReader readSourceImage()... line 208, at: ParameterBlockJAI readParams = new ParameterBlockJAI("ImageRead", "rendered"); That call actually throws the IllegalArgumentException. Does anyone have any idea why this would work some times, and other times it won't? I have JAI installed, and it does work some of the time as the images actually are properly rendered and no exception is thrown.
