pnmarith(1) General Commands Manual pnmarith(1)NAME
pnmarith - perform arithmetic on two portable anymaps
SYNOPSIS
pnmarith -add|-subtract|-multiply|-difference|-minimum|-maximum. pnmfile1 pnmfile2
DESCRIPTION
Reads two portable anymaps as input. Performs the specified arithmetic operation, and produces a portable anymap as output. The two input
anymaps must be the same width and height.
The arithmetic is performed between corresponding pixels in the two anymaps, as if maxval was 1.0, black was 0.0, and a linear scale in
between. Results that fall outside of [0..1) are truncated.
The operator -difference calculates the absolute value of pnmarith -subtract pnmfile1 pnmfile2, i.e. no truncation is done.
All flags can be abbreviated to their shortest unique prefix.
