Declaration [src]
cairo_surface_t*
gdk_window_create_similar_surface (
GdkWindow* window,
cairo_content_t content,
int width,
int height
)
Description [src]
Create a new surface that is as compatible as possible with the
given window
. For example the new surface will have the same
fallback resolution and font options as window
. Generally, the new
surface will also use the same backend as window
, unless that is
not possible for some reason. The type of the returned surface may
be examined with cairo_surface_get_type().
Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.)
Available since: 2.22
Parameters
content
-
Type:
cairo_content_t
The content for the new surface.
width
-
Type:
int
Width of the new surface.
height
-
Type:
int
Height of the new surface.
Return value
Type: cairo_surface_t
A pointer to the newly allocated surface. The caller
owns the surface and should call cairo_surface_destroy()
when done
with it.
This function always returns a valid pointer, but it will return a
pointer to a “nil” surface if other
is already in an error state
or any other error occurs.
The caller of the method takes ownership of the data, and is responsible for freeing it. |
