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").

OPTIONS

       Options for setting attribute values include:

       -chromaticities f f f f f f f f

              for the white point (8 floats)

       -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
              additional information about the image (string)

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

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

       -longitude f, -latitude f, -altitude f
              location  where  the  image  was  recorded,  in  degrees east of
              Greenwich and north of the equator,  and  in  meters  above  sea

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

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

       -screenWindowCenter f f
              center of the screen window (2 floats)

       -h     prints these options
