Declaration [src]

gboolean
rsvg_handle_has_sub (
  RsvgHandle* handle,
  const char* id
)

Description [src]

Checks whether the element id exists in the SVG document.

Element IDs should look like an URL fragment identifier; for example, pass #foo (hash foo) to get the geometry of the element that has an id="foo" attribute.

Available since:

2.22

Parameters

`id`	`const char*`
	An element’s id within the SVG, starting with “#” (a single hash character), for example, `#layer1`. This notation corresponds to a URL’s fragment ID.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.

Return value

Returns:	`gboolean`
	`TRUE` if `id` exists in the SVG document, `FALSE` otherwise.
