Thank you.
I think that I am missing some crucial information here.
Do I, using the Lat/Lon limits of my overlay map, create my own images for
EACH zoom type ?
Based on the Google world coordinate system ?
Let's assume that I have an image that is 1000 by 1000 pixels and is between
(44 , 45) lat and (70 , 71) lon
I don't want to show it between . zoom level 6 and 17
So now I have to create 11 sets of 15 tiles ?
In the missouristate example, one of the tiles is:
http://search.missouristate.edu/map/tilesets/baselayer/15_7893_12731.png
I understand the zoom level, but not sure about the 7829 and 12731.
I presume I leave the areas I have no maps blank ?
the website returns "blanktile.png" if it is not matched. How does that work
?
Thanks you
Ahmet

I think I answered my own question:
"There is a ImageMapType class that seems to be designed for this
purpose."
Now.. I could not find any (short) examples of the ImageMapType class.
Anybody knows where ?
Thanks
