Hi, I am using GroundOverlay to display patterned images on the map with 80% transparency.
If the images overlap, I want to alter the images so that they merge such that: - If either image has a green pixel then this is shown; - followed by yellow; - the image of the map is still shown through the pattern I have tried using a custom blendShader (using Pixel Bender) but this does not work as the map image becomes part of the blend. I have tried manually altering the raw bitmapdata of the GroundOverlay but I can never exactly calculate the overlap rectangle of the two images. I have also tried using OverlayBase but this never seems to project the same as GroundOverlay. 1. Is it possible to use a blendShader with Google Maps to achieve this? 2. Can I find the overlap rectangle of the two Ground Overlay so I can alter pixels in both images for the desired results? 3. Can I manipulate pixels of a GroundOverlay at the current zoom level? 4. Is there any other way of doing this? I am stuck! Thank you for any help you can give me on this.
