#X text 11 -499 Numeric Operators (numop): transform an image or video
by applying a mathematical operation to each pixel value in the grid.
;
#X text 12 -445 To transform a grid (in this case an image) using numop
\, it must first be given an argument (a number value) in order to
affect a pixel value. The examples here show you the three methods
that can be used to give the numop an argument.;

#X text 10 -618 GridFlow performs high level grid processing \; in
other words its main function is the manipulation of images and video.
There are several ways to madify images in GridFlow \, some are very
basic while others are more advanced (and are saved for the intermediate
tutorials.) In this section we will introduce some very basic functions
of the numeric operator \, one of the most common methods used for
image transformation.;
