IDirectFBDisplayLayer | SetClipRegions

#### Set the clipping region(s).

DFBResult SetClipRegions (
| IDirectFBDisplayLayer |  | * | thiz,
| const DFBRegion |  | * | regions,
| int |  |  | num_regions,
| DFBBoolean |  |  | positive
);

If supported, this method sets the clipping regions that are used to to enable or disable visibility of parts of the layer. The num_regions must not exceed the limit as stated in the display layer description.

If positive is DFB_TRUE the layer will be shown only in these regions, otherwise it's shown as usual except in these regions.

Also see IDirectFBDisplayLayer::GetDescription().
