The following classes represent placeholder shapes. A placeholder most commonly appears on a slide, but also appears on a slide layout and a slide master. The role of a master placeholder and layout placeholder differs from that of a slide placeholder and these roles are reflected in the distinct classes for each.

There are a larger variety of slide placeholders to accomodate their more complex and varied behaviors.
