the image. This is a level 1 adjustment and will affect the whole image.
The adjustment procedure is similar for all the modes. The only thing to keep in mind is the order in which the points will be adjusted
i.e. always start with the lowest level points and end with the highest level zones (see Geometry distortions/level hierarchy) .
A 3x3 mode adjustment gives the following new points to be adjusted ( the 4 points of the 2x2 mode being already adjusted : they
