pamtopnm
converts PAM images to PNM format
TLDR
Convert PAM to PNM format
$ pamtopnm [input.pam] > [output.pnm]
Convert, overriding tuple type check with -assume$ pamtopnm -assume [input.pam] > [output.pnm]
Convert silently without informational messages$ pamtopnm -quiet [input.pam] > [output.pnm]
SYNOPSIS
pamtopnm [-assume] [-quiet] [file]
DESCRIPTION
pamtopnm reads a PAM image as input and produces an equivalent PBM, PGM, or PPM (i.e. PNM) image as output. The output format is chosen automatically based on the input: BLACKANDWHITE becomes PBM, GRAYSCALE becomes PGM, and RGB becomes PPM.If the input PAM does not have an appropriate tuple type (BLACKANDWHITE, GRAYSCALE, or RGB) and depth, pamtopnm fails unless -assume is specified. To force conversion of images with extra channels, run the input through pamchannel first to select the desired channels.Part of the Netpbm toolkit.
PARAMETERS
-assume
Override the tuple type requirement. Asserts that the tuples contain valid PBM, PGM, or PPM data regardless of the PAM tuple type. The depth must still conform to the target format.-quiet
Suppress informational messages to standard error.
