1. Main functions
Get the affine area of an image, cut the InputImage to get a new outputImage. It is used to positively transform the area to be processed with the coordinate axis of template matching. It is to cut on the output image of Fixture. The coordinates of each point in this area are the coordinates of the Fixture, which is the 2D transformation relationship obtained by PMAling template matching.
2. Settings
Region shape: refers to the shape of the cut region.
Selection mode: the origin is the upper left corner, and the center is the center point.
The blue frame is the area to be cut. In the subsequent processing, the cutting area is not based on the upper left corner of the area as the origin, but based on the coordinates calibrated by FixtureTool 2D transformation.
