exrstdattr - a utility for modifying OpenEXR standard attributes.

       This manual page was written by Andrew Lau <netsnipe@users.sourceforge.net>,  for  the  Debian  GNU/Linux
       system (but may be used by others).

       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").

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

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

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

       -commentss
              additional information about the image (string)

       -capDates
              date when the image was created or captured,  in  local  time  (string,  formatted  as  YYYY:MM:DD
              hh:mm:ss)

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

       -longitudef,-latitudef,-altitudef
              location  where the image was recorded, in degrees east of Greenwich and north of the equator, and
              in meters above sea level (float)

       -focusf
              the camera's focus distance, in meters (float, > 0, or "infinity")

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

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

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

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

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

       -screenWindowWidthf
              width of the screen window (float, >= 0)

       -screenWindowCenterff
              center of the screen window (2 floats)

       -h     prints these options
