Description
Pixbufs are client-side images. For details on how to create and manipulate pixbufs, see the GdkPixbuf API documentation.
The functions described here allow to obtain pixbufs from GdkSurfaces and cairo surfaces.
Functions
gdk_pixbuf_get_from_surface ()
GdkPixbuf * gdk_pixbuf_get_from_surface (cairo_surface_t *surface
,int src_x
,int src_y
,int width
,int height
);
Transfers image data from a cairo_surface_t and converts it to an RGB(A) representation inside 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.
gdk_pixbuf_get_from_texture ()
GdkPixbuf *
gdk_pixbuf_get_from_texture (GdkTexture *texture
);
Creates a new pixbuf from texture
. This should generally not be used
in newly written code as later stages will almost certainly convert
the pixbuf back into a texture to draw it on screen.
