Constructor Details
#initialize(clip_path_units = 'userSpaceOnUse') {|_self| ... } ⇒ ClipPath
Create a clipping path. Within the block create an outline from one or more paths, basic shapes, text objects, or use
. Everything drawn within the outline will be displayed. Anything drawn outside the outline will not.
If the clipping path contains a use
, it must directly reference path, basic shape, or text objects.
Attach the clipping path to an object with the :clip_path style.
