# pnmcomp(1)

replaced by pamcomp

## NAME

**pnmcomp** - replaced by pamcomp

## DESCRIPTION

This program is part of **Netpbm**(1) .

**pnmcomp** was obsoleted by [**pamcomp**(1)](/pamcomp/1.md) , introduced with Netpbm 10.21 (March 2004).  **pamcomp** is backward compatible with **pnmcomp**, plus adds many additional functions.  Among this is the ability to process PAM images, including those with transparency channels.

**pnmcomp** remained in the Netpbm package until Netpbm 10.68 (September 2014) because of hopes that it had fewer bugs than **pamcomp** because of its age.  But now it would just be clutter.

In Netpbm before 10.21, use the manual for **pamcomp** with **pnmcomp**.  Features that are in **pamcomp** but not **pnmcomp** are indicated by statements that they didn't exist before 10.21.
