You can set the size of the tiling grid using the following
method:
The rectangle that delimits the tiling grid is expressed
in the manager coordinates. Only the tiles that intersect with this
rectangle can be loaded. You can see an example of a tiling grid whose
size has been defined in the debug view illustrated in
Load-on-demand debug view.
Note
The tiling parameters introduced in this section (size
of the tiles, origin tile, and size of the tiling grid) can be configured
for each tiled layer in a manager. This allows you to have in the
same manager large-tile layers containing objects displayed at a small
scale and small-tile layers containing objects displayed at a large
scale.
