ppmflash (1)
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.
