Detailed Description

A clipping path is used to mark an area within a page to be highlighted or removed.

The clipping path clips out part of the design. A clip can also be used with text.

The clipping path defines an area within a page (text or graphic) that will be highlighted or removed. For example, a clipping path could be used to remove the background in a photograph, to highlight a person or object in front, or to super-impose text over an image. Only part of the image appears through a shape created with the clipping path.

The Clip class is made up of a list of path and text elements. Any element can have a clip associated with it, and clip objects can hold arbitrary levels of nested container and group objects.

If a group object is inside a clip object, and the clip object also contains at least one text object and no path objects, the group object has a special meaning. All text objects contained in a group object like this are considered to be part of the same BT/ET block. This means that the union of these text objects makes up a single clipping path. The text objects do not intersect.
