Tiling image region?

Hi.

I want to tile some region of image, but I no have any idea to implement it.

I want to make some thing like define the X and Y size of region and then tile with image.

Not sure whether you want to tile an image to a specific area of screen...
Setviewport, tileimage
or tile an image onto another image...
drawimage, setviewport, tileimage, grabimage
