ROI: Set the start point coordinates (x, y), width, height, and tilt angle of the region of interest (ROI).
Method: Counts pixels between a range of gray values or counts pixels along an edge transition. Count Edge Pixels counts pixels along the edges of objects. Count Gray Pixels counts pixels that fall within the specified range of gray values.
Low/High Threshold: Sets the pixel value(s) to be located for Count Gray Pixels (0 = black, 255 = white).
Edge Threshold: Sets the pixel value(s) to be located for Count Edge Pixels (0 = black, 255 = white).
Min/Max Pixel Count: Sets the tolerance on the minimum and maximum number of pixels allowable for the inspection to pass.
