## NAME
       ppmbrighten - replaced by pambrighten


## DESCRIPTION
       This program is part of [**Netpbm**(1)](https://www.chedong.com/phpMan.php/man/Netpbm/1/markdown).

       Starting  with  Netpbm  10.86  (March 2019), **ppmbrighten **is obsolete.  Use [**pambrighten**(1)](https://www.chedong.com/phpMan.php/man/pambrighten/1/markdown) in‐
       stead.

       **pambrighten **is mostly backward compatible with **ppmbrighten**.  You can use the **pambrighten **man‐
       ual 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**.
