Description
The number of units that span the width of the image, in terms of integer ClipPath coordinates.
All horizontal 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 left side of the image and 1.0 represents the right side of the image.
Note that the choice of value for XClipPathUnits will influence the choice of DataType for the ClipPath commands, since SSHORT or even SBYTE values may be usable if XClipPathUnits is smaller, while SLONG will be required if XClipPathUnits is larger.
Required for every TIFF ClipPath.
