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.

Parameters
Filter
he type of edge finding that is employed. The 3x3 filter requires a harder edge than the 5x5 filter
SmoothIterations
Number of times the image is smoothed before edge detection is
carried out
Sensitivity
The minimum edge level. Increasing sensitivity eliminates weaker edges.
Analysis
Output
The Output Property Page determines what the tool does with the angle it finds.
No Image Rotation If it is set to "No Image Rotation" the image and the tools ROI will remain unchanged.
Rotated ROI The ROI will be adjusted according to the image angle.
Rotated ROI ImageThe Image under the ROI will be rotated straight (cropped according to the ROI.)
Rotated Image Sub The Image will be rotated straight with cropping ie image size is maintained.
Rotated Image The Image will be rotated straight without any cropping ie image size is variable.
