# pnmscale(1)

replaced by pamscale

## NAME

pnmscale - replaced by pamscale

## DESCRIPTION

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

**pnmscale** was obsoleted by [**pamscale**(1)](/pamscale/1.md) , introduced with Netpbm 10.20 (January 2004).  **pamscale** is backward compatible with **pnmscale**, plus adds many additional functions, including the ability to process PAM images.

**pnmscale** remained in the Netpbm package until Netpbm 10.46 (March 2009) because of hopes that it had fewer bugs than **pamscale** because of its age.  But now it would just be clutter.

In Netpbm before 10.20, use the manual for **pamscale** with **pnmscale**.  Features that are in **pamscale** but not **pnmscale** are indicated by statements that they didn't exist before 10.20.
