normpat
NORMPAT(1) General Commands Manual NORMPAT(1)
NAME
normpat - normalize RADIANCE pictures for use as patterns.
SYNOPSIS
normpat [ -v ][ -b ][ -f ][ -r maxres ] picture ..
DESCRIPTION
Normpat normalizes one or more RADIANCE pictures to an average brightness of 1.0 and optionally removes fundamental frequencies and blends
the edges of the image. The original images are overwritten during this process, and it is recommended that the program work on copies of
the pictures for this reason.
The -r option can be used to set the maximum horizontal or vertical resolution of the final result, which should not be greater than 256
for most patterns (due to the associated memory burden during rendering). The -f option uses a Fourier transform to remove the lowest fre-
quencies from the image, reducing the noticeability of pattern repitition. The -b option can be used to blend the edges of the image so
that when it is tiled, the seams are less apparent. The -v option turns on the verbose flag, which prints on the standard output progress
messages as the script runs.
Normpat is a shell script that makes calls to other RADIANCE programs that do the actual work.
