hdifftopam(1)

hdifftopam1

Convert horizontal difference image to original pam image

Usage

hdifftopam[pamfile] [-pnm] [-verbose]

Minimum unique abbreviation of option is acceptable. You may use double hyphens instead of single hyphen to denote options. You may use white space in place of the equals sign to separate an option name from its value.

Overview

This program is part of Netpbm(1) .

hdifftopam undoes what pamtohdiff does.

Options

In addition to the options common to all programs based on libnetpbm (most notably -quiet, see
Common Options ⟨index.html#commonoptions⟩ ), hdifftopam recognizes the following command line options:

-pnm

This option tells hdifftopam to create a PNM image (i.e. PGM or
PPM). Without it, hdifftopam creates a PAM image (with a
tuple type of "unhdiff"). If the PAM does not have the proper depth
to be a PGM or PPM (i.e. 1 or 3) and you specify -pnm,
hdifftopam fails.

-verbose

Print output image width, height, depth and maxval to standard error.
