How to use

The image that we want to process is made of 256 rows and 256 columns of coloured cells starting from cell A1. The cells are sized 1 pixel by 1 pixel. One source of such images could be the Mandelbrot fractal generator app.

Click the various buttons below the input image to process it. The image is processed and the output shown in the cells starting from A270.

Macros must be enabled for this app to work.
