The following window will then appear:
To define the first keypoint, which has the coordinates x = 0 and y = 0:
Enter keypoint number 1 in the appropriate box, and enter the x,
y coordinates: 0, 0 in their appropriate boxes (as shown earlier). Click
Apply to accept what you have typed.
Enter the remaining keypoints using the same method.
Note: When entering the final data point, click on OK to indicate that
