Gdkpixbuf_get_from_surface
deprecated: 4.12
Declaration [src]
GdkPixbuf*
gdk_pixbuf_get_from_surface (
cairo_surface_t* surface,
int src_x,
int src_y,
int width,
int height
)
Description [src]
Transfers image data from a cairo_surface_t
and converts it
to a GdkPixbuf
.
This allows you to efficiently read individual pixels from cairo surfaces.
This function will create an RGB pixbuf with 8 bits per channel.
The pixbuf will contain an alpha channel if the surface
contains one.
Deprecated since: 4.12
Use GdkTexture
and subclasses instead
cairo surfaces and pixbufs.
