# Region

Use the Region tab to define the type of region that will be applied to the Current.InputImage buffer. Alternatively you can manipulate the region graphic over the Current.InputImage image.

It may be easier to first specify the projection region graphically, then use this tab to fine tune the projection region parameters.
