Function

Gimpcairo_surface_create_buffer

since: 2.10

Declaration [src]

GeglBuffer*
gimp_cairo_surface_create_buffer (
  cairo_surface_t* surface,
  const Babl* format
)

Description [src]

This function returns a GeglBuffer which wraps surfaces pixels. It must only be called on image surfaces, calling it on other surface types is an error.

If format is set, the returned GeglBuffer will use it. It has to map with surface Cairo format. If unset, the buffer format will be determined from surface. The main difference is that automatically determined format has sRGB space and TRC by default.

Available since: 2.10
