Method

CoglPipelineset_layer_point_sprite_coords_enabled

Declaration [src]

gboolean
cogl_pipeline_set_layer_point_sprite_coords_enabled (
  CoglPipeline* pipeline,
  int layer_index,
  gboolean enable,
  GError** error
)

Description [src]

When rendering points, if enable is TRUE then the texture coordinates for this layer will be replaced with coordinates that vary from 0.0 to 1.0 across the primitive. The top left of the point will have the coordinates 0.0,0.0 and the bottom right will have 1.0,1.0. If enable is FALSE then the coordinates will be fixed for the entire point.

Parameters

layer_index

Type: int

The layer number to change.

enable

Type: gboolean

Whether to enable point sprite coord generation.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the function succeeds, FALSE otherwise.
