Using the Image Registration Translate & Rotate Tools

When creating, editing (only Full Editing Mode), or copying an SRO, the Translate & Rotate tools will become available, along with several useful keyboard shortcuts. Press the Translate & Rotate button to toggle the Translate & Rotate tools. Use the Translate & Rotate dropdown to use the following controls:

  • Mode: Selecting Translation & Rotation will enable both translations and rotations. Selecting Translation Only will disable rotations.
  • Allow Arbitrary Center of Rotation: Leave this checked if you wish to be able to move the center of rotation (see instructions below). Uncheck this box is you wish to disable this feature.
  • Reset Center of Rotation: Press this button to reset the center of rotation to the center of the secondary image set.

A yellow guide will appear in the in all three views when the Translate & Rotate tools are active. The guide consists of three distinct regions:

  • Inside Inner Circle (only available if Allow Arbitrary Center of Rotation is checked): Press and hold your mouse within this region to drag the center of rotation to another position.
  • Outside Inner Circle, Inside Outer Circle: Press and hold the mouse within this region to translate the secondary image set.
  • Outside Outer Circle: Press and hold the mouse within this region to rotate the image set about the center of rotation (the center of the crosshairs).
