Dear Sir/Madam,
I have a SDK where i am able to create raster images based on center’s coordinates, on standard Mercator. I want to use these images as overlay on openlayers.
How can i create the tiles ? can i use any open source GIS to help me ? is any source where can i search ?
When you want to create your own tiles from raw OSM data you should have a look programs like Mapnik, Tilemill or Maperitive, to name but a few.
You can find first information in the OSM wiki about these programs. Also have a look there for the keyword “Rendering”.
There are different possibilities to feed the mentioned programs with raw OSM data. If you need Tiles for a bigger area you should think about using a database as source. Information and HowTos about that are at http://switch2osm.org
Also look at http://help.openstreetmap.org and do a search there for “tiles” or “rendering”.

ein geotif kannst du zum zb. mit:
http://code.google.com/p/tilers-tools/
in ein tiles-dir umwandeln.
gdal_tiler.py --to=zxy --zoom=11 your.tif --dest-dir=your_dist-dir
