ppmflash - brighten a picture up to complete white-out


SYNOPSIS

       ppmflash flashfactor [ppmfile]


DESCRIPTION

       Reads a portable pixmap as input. Increases its brightness
       by the specified  flashfactor  up  to  a  total  white-out
       image.   The  flashfactor  may  be  in  the range from 0.0
       (original picture's brightness) to  1.0  (full  white-out,
       The Second After).

       As  pnmgamma  does not do the brightness correction in the
       way I wanted it, this small program was written.

       This program is similar to ppmbrighten , but  not  exactly
       the same.
