Area extraction
Function Extracts a rectangular area from the whole scannable area.
Usage Use area extraction when you want to extract a portion of an image.
For example, when you want to extract a photograph from a page,
define a rectangle over the photograph, as shown below. You
determine the position of the area by setting the X and Y
coordinates of the upper left corner of the rectangle. You determine
the size of the area by setting the vertical and horizontal lengths,
which you can set separately.
