how to merge an array of bitmap together in one bitmap ?

[freeaks]

hi there,

how can i merge together in one single bitmap the content of a bitmap array ?

here's my render method:

//here's what i have:
for (int x = 0; x < MapLoader.width; x++) {
  for (int y = 0; y < MapLoader.height; y++) {
    g.drawBitmap( picSource[x][y], posX, posY, BitmapPaint);
  }
}

//and here's what i'd like to have:
g.drawBitmap( picDest, posX, posY, BitmapPaint);

i would like to itterate through picSource[x][y] grab all the bitmap and put them all in picDest.
note that no bitmap contained in the picSource[][] array is located a the same position ..
there's no bitmap on top of any other, they're just displayed in a grid
each is a 32x32 bitmap in a 4x3 grid for example..
each its own spot on the grid ..

thanks for the help
