/* The binary functions will be working on a `uint8_t' type dataset with
values of 1 or 0 (no other pixel will be touched). However, in some
cases, it is necessary to put temporary values in each element during
the processing of the functions. So if your input datasets have values
other than 0 and 1 that you don't want these functions to work on, be
sure they are not equal to this value. It is chosen as the immediate
value before the maximum value for this type (which is the blank value
for this type), so blank values will also not be touched by this
function. */
