    ### Tiled Images

    With the `g` (or `fg`) option you can get an xml file containing tiling information. To use the tiling, special parameters `x`, `y` and `z` can be used. `x` and `y` specify which tile should be returned. `z` specifies how far zoomed out the images are. For `x` and `y` refer to `num_tiles_x` and `num_tiles_y` respectively from the xml. `z` maps to the index of each pyramid_level, 0 being the most zoomed out.
