.TH ppmflash 1 "16 November 1993" .IX ppmflash .SH NAME ppmflash - brighten a picture up to complete white-out .SH SYNOPSIS ppmflash .I flashfactor .RI [ ppmfile ] .SH 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). .PP As .I pnmgamma does not do the brightness correction in the way I wanted it, this small program was written. .PP This program is similar to .I ppmbrighten , but not exactly the same. .SH SEE ALSO ppm(5), ppmdim(1), pnmgamma(1), ppmbrighten(1) .SH AUTHOR Copyright (C) 1993 by Frank Neumann .\" Permission to use, copy, modify, and distribute this software and its .\" documentation for any purpose and without fee is hereby granted, provided .\" that the above copyright notice appear in all copies and that both that .\" copyright notice and this permission notice appear in supporting .\" documentation.
