Constructing the data set from a picture in a Mathematica notebook.

Motivation

Often a Mathematica literature shows a photo without a dataset. As an example, the Mathematica book gives an example of the function, ListConvolve, using the photo of a fish, but it does not give the dataset.

Here this little animation teaches how to reconstruct the data set.

There is another way of reconstructing the dataset using hexadecimal number and string manipulation, but that is in the notebook form.
