# ppmbrighten(1)

replaced by pambrighten

## NAME

ppmbrighten - replaced by pambrighten

## DESCRIPTION

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

Starting with Netpbm 10.86 (March 2019), **ppmbrighten** is obsolete.  Use [**pambrighten**(1)](/pambrighten/1.md)  instead.

**pambrighten** is mostly backward compatible with **ppmbrighten**.  You can use the **pambrighten** manual for **ppmbrighten** as long as you ignore features that were added after Netpbm 10.86.

One way in which **pambrighten** is not backward compatible is that\
   **pambrighten** does not have a **-normalize** option.  If you want\
   that function, use **pnmnorm** on the image before passing it to\
   **pambrighten**.

Another backward incompatibility is that **pambrighten** produces the\
   same kind of output as the input, whereas **ppmbrighten** always\
   produces PPM.  If you need PPM output, pass the results through\
   **ppmtoppm**.

**ppmbrighten** is currently implemented as a triviel program that\
   invokes **pambrighten**, **pnmnorm**, and **ppmtoppm**.
