This is how it goes.
Ffirst of all you need a square image and load it into db.
I am assuming this works in DB but you'll have to try it first because i've been programming in DBPro most of the time.
`load the image
prepare matrix texture matnum,numoftilesx,numoftilesy
set matrix tile matnum,tilenum
`the tilenum is the reference code to the bitmap you just prepared
`the number goes left -> right and top -> bottom
`so the top right square of an image split 2 by 2 would equal '1'
if you get an error with set matrix tile it's most likely you've got the image size wrong (make sure the image is square) or the tile number is wrong.
