Method

CoglBitmapset_access

Declaration [src] 

void
cogl_bitmap_set_access (
  CoglBitmap* bitmap,
  CoglBufferAccess access
)

Description [src]

Restricts access to the underlying storage. Bitmaps allow both reading and writing by default. Device mappings that are only writable can use COGL_BUFFER_ACCESS_WRITE so pixel readback performs any operations that require reading pixels in temporary storage.

The bitmap must not be mapped or bound. Bitmaps sharing the same storage share the access restriction.

Parameters

access

Type: CoglBufferAccess

The allowed access to the bitmap’s storage.
