+image transformation.;

+are several ways to modify images in GridFlow \, some are very basic
+while others are more advanced.;

+#X text 8 277 To transform a grid the numop must first be given an
+argument. That argument will be applied to every pixel in the grid.
+The following three examples show some ways to give the numop an argument.
