pamoil

Turn a PAM image into an oil painting. More information: https://netpbm.sourceforge.net/doc/pamoil.html.

• Turn a PAM image into an oil painting:

pamoil path/to/input_file.pam > path/to/output_file.pam

• Consider a neighborhood of N pixels for the "smearing" effect:

pamoil -n N path/to/input_file.pam > path/to/output_file.pam
