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.


surface cairo_surface_t

Surface to copy from.

 The data is owned by the caller of the function.
src_x int

Source X coordinate within surface.

src_y int

Source Y coordinate within surface.

width int

Width in pixels of region to get.

height int

Height in pixels of region to get.

Return value

Returns: GdkPixbuf

A newly-created pixbuf with a reference count of 1

 The caller of the function takes ownership of the data, and is responsible for freeing it.
 The return value can be NULL.
