Description
The number of units that span the height of the image, in terms of integer ClipPath coordinates.
All vertical ClipPath coordinates will be divided by this value in order to get a number that is (usually) between 0.0 and 1.0, where 0.0 represents the top of the image and 1.0 represents the bottom of the image.
Use this if you want to be able to specify your ClipPath coordinates using integer values that match the aspect ratio of an image.
Unlike the XClipPathUnits field, this field is optional. If it's not present, the default YClipPathUnits = XClipPathUnits applies.
