The Tile Generator is pretty much as the title implies - a small program to create map tiles compatible with Google Maps. It can draw shapes, lines, text and images on the tiles in proper Mercator projection. Tile definitions can be created directly from the program or imported from an XML definition.
I don't have any working examples but I hope the program is sufficiently self-explanatory.
I started the project some time ago, but got away from it due to lack of time and resources. However I do see some potential in this for easily creating custom tiles.
