dt_backbuf_t Struct Reference

#include <pixelpipe_hb.h>

Collaboration diagram for dt_backbuf_t:

Data Fields
size_t	bpp
size_t	width
size_t	height
dt_atomic_uint64	hash
dt_atomic_uint64	history_hash

Detailed Description

this encapsulates the pixelpipe. a develop module will need several of these: for previews and full blits to cairo and for the export function.
