poIImagePlane ManipIdentity
Clears the 2D or 3D user transform for the image plane.
Syntax
Imageplane_handle ManipIdentity
Application
HyperView Tcl Modify
Description
The image plane maintains a separate user transform to track the position, rotation, and scaling applied to the image plane. This command resets the transform, however it does not alter any data regarding alignment of a 3D image plane to a model.
