PerspectiveDeskewCommand Class
Summary
Detects and automatically deskews a document in three dimensions. Usually used to correct perspective distortion (deskew) introduced by the camera’s perspective in relation to the subject (usually a document).

- For the best detection results, the document's boundaries should be inside the captured view and have a different background color than the background of the captured view.
- The PerspectiveDeskewCommand can change the specified image. To keep the original image unchanged, use this function on a copy.
-
Use the PerspectiveDeskewCommand if there is depth (z-axis) deformation as well as deformation along the x- and y- axes. Use the DeskewCommand to fix 2D orientation. Unlike the DeskewCommand, the PerspectiveDeskewCommand does not look at the content of the captured document.
-
If the PerspectiveDeskewCommand fails to correct the skew, the original image is not changed.
- This function supports 24 and 32-bit color images.
- This command supports signed/unsigned images.
