The Scene Angle Tool measures the angle of an image. Additionally, the Scene Angle Tool can rotate the ROI to match the image angle or rotate the image in the viewer so it appears straight.

Using the Scene Angle Tool

When the Scene Angle Tool is selected in a sequence its ROI will appear on the viewer window. The ROI positions determines where the tool will look to get the angle of the image.  When the tool is run it records the image's angle in its parameters page.  The Scene Angle Property page determines how the tool interprets what the image angle is, and the Rotate property page determines if and how the angle is applied to the image or ROI.
