| Checker |
Function
The Checker function generates a checkerboard within the width and height
of the image. It is handy to test Warps, or to split a screen
in half. To make a specific number of tiles per row or column (for example,
4 x 4), divide the
width and the height by the number—height/4
yields 4 rows.
