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.
