PROGRAM:
NAME
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.
Use ppmflash online using onworks.net services
