NAME

       exrstdattr - a utility for modifying OpenEXR standard attributes.

SYNOPSIS

       exrstdattr [options] infile outfile

DESCRIPTION

       This  manual  page documents briefly the exrstdattr command.  This manual page was written
       for the Debian distribution because the original program does not have a manual page.

       exrstdattr reads an OpenEXR image from infile, sets the values of  one  or  more  standard
       attributes  in  the  image's header, and saves the result in outfile. Note that infile and
       outfile must not refer to the same file (i.e. the program cannot edit an  image  file  "in
       place").

       -whiteLuminance f
              white luminance, in candelas per square meter (float, >= 0.0)

       -xDensity f
              horizontal output density, in pixels per inch (float, >= 0.0)

       -owner s
              name of the owner of the image (string)

       -comments s

       -utcOffset f
              offset of local time at capDate from UTC, in seconds (float, UTC == local time + x)

       -longitude f, -latitude f, -altitude f

       -expTime f
              exposure time, in seconds (float, >= 0)

       -aperture f
              lens apterture, in f-stops (float, >= 0)

       -isoSpeed f
              effective speed of the film or image sensor that  was  used  to  record  the  image
              (float, >= 0)

       -envmap s
              indicates that the image is an environment map (string, LATLONG or CUBE)

       -pixelAspectRatio f
              width divided by height of a pixel (float, >= 0)

       -screenWindowWidth f
