NAME
     imgexp - expand the range of pixel values in an image.

SYNOPSIS
     /usr/sbin/imgexp inimage outimage [min max]

DESCRIPTION
     imgexp expands the range of pixel values in an image.  Pixel values less
     than or equal to min are mapped to 0, while pixel values greater than or
     equal to max are mapped to 255.  If min and max are not provided on the
     command line, then the minimum and maximum pixel values in the image are
     used.  This can be used to manipulate the contrast of images.
