Clipping involves positioning one object inside another, creating a parent - child layer relationship. The path of the parent object becomes the new boundaries for the child object. Any areas of the child object which lie outside the parent object's path are masked (hidden).
Clipping can also be used to confine an adjustment or mask to a single layer or layer group.
Objects can be clipped manually or automatically on object creation; the latter by drawing directly inside a selected object.
When scaling a parent object, child (clipped) objects scale to maintain the correct aspect ratio. Scaling a clipped object has no effect on the parent object. A clipped object can be edited independently from its parent, e.g. adjusting opacity and/or blend mode.
Any object can act as a parent or child in clipping relationships. Therefore both vector objects and pixel layers can be either clipped or be subject to clipping.
