In the secondary output:
where do these numbers come from?
If you're counting the number of times a digit appears in the input, 0 occurs 13 times (not 12 times) in your sample input. If you're counting the number of times a value appears in your sample input, 0 (or 00) does not appear at all???
All of your input values are two digit strings. Are we supposed to treat 01 and 1 as the same value or as distinct values? If they are the same, is 010 to be treated as an octal value (decimal 8) or as a decimal value (10)?

ppmdist
ppmdist(1) General Commands Manual ppmdist(1)NAME
ppmdist - simplistic grayscale assignment for machine generated, color images
SYNOPSIS
ppmdist [-intensity|-frequency] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input, performs a simplistic grayscale assignment intended for use with grayscale or bitmap printers.
Often conversion from ppm to pgm will yield an image with contrast too low for good printer output. The program maximizes contrast between
the gray levels output.
A ppm input of n colors is read, and a pgm of n gray levels is written. The gray levels take on the values 0..n-1, while maxval takes on
n-1.
The mapping from color to stepped grayscale can be performed in order of input pixel intensity, or input pixel frequency (number of repeti-
tions).
OPTIONS -frequency Sort input colors by the number of times a color appears in the input, before mapping to evenly distributed graylevels of
output. -intensity Sort input colors by their grayscale intensity, before mapping to evenly distributed graylevels of out-
put. This is the default.
BUGS
Helpful only for images with a very small number of colors. Perhaps should have been an option to ppmtopgm(1).
