Searching for some sample code for converting a point in WGS84 coordinate system to a map position in Google Maps (pixel position), also supporting zoom levels.
If the codes is well commented, then it can also be in some other language.
You can also point me to a open source Java project :)
Some resources found:
OpenLayer implementation.
JOSM project
Excellent Java Map Projection Library from JH LABS. This is a pure java PROJ.4 port. Does projection from WGS84 to meters. From there it's quite straightforward to convert meters to tile pixels.
Tile utility code in Java on mapki.com (great resource for google map developers)
