NAME

       exrnormalize - normalize an OpenEXR image

SYNOPSIS

       exrnormalize input.exr output.exr [ maxval ]

DESCRIPTION

       Normalizes  an  OpenEXR  file to [0,1] such that the brightest pixel in
       the image has one of its RGB components set to 1.  If a  maximum  value
       is  given  on  the  command  line,  then  that value is used instead of
       scanning the image.
