Set the target surface for a layer
#include <gf/gf.h>
void gf_layer_set_surfaces( gf_layer_t layer,
gf_surface_t surface[],
int nsurfs );
- layer
- The handle for a layer.
- surface
- An array of surface handles for the layer to use.
- nsurfs
- The number of items in the surface array.
gf
This function sets the target surface or surfaces for a layer.
|
- In general, a layer targets a single surface. However some planar formats (for example, YUV) use one surface per plane.
- Changes to the layer's paramters are enqueued. You need to call gf_layer_update() to make them take effect.
