Hi All, I've been trying to use a bitmap displayed via a groundOverlay to show users where data is available for on the server. These are basically "cells".
Now by loading the bitmap into memory, doing a little maths, I can allow or disallow the user to click the map, which will then go on to get the data back from the server. All works fine. But I then tried to display this bitmap on the map itself to give some visible indication of where the user could click. First of all I just took the image, drew it on screen. The bitmap is 100x100 pixels, with each pixel being representative of 0.1 x 0.1 degrees (or overall area being 10 x 10 degrees). Of course, this won't work if the bounds of the image is much more than 0.5 0.5 degrees as an image like that is Cartesian coords., whereas Google maps is Mercator and the location of the image on screen doesn't line up with the underlaying "grid". So, I went on to slice the image into horizontal strips, 1 pixel tall, 100 pixels wide. Groundoverlay these 0.1 degree tall and 10 degrees wide gives you 100 groundOverlays. Now this projects the image correctly so mouse moves tally correctly with where users can click, but now got a pretty awful looking screen. It appears when you groundOverlay, the images are not drawn pixel perfect.

I really need to get this working and cannot wait until correctly projected images make it into the Google Maps API (if it ever does).
