              Print runtime statistics

       --mipimage %s
              Specify an individual MIP level

       Basic modes (default is plain texture):

              --shadow
                     Create shadow map

              --envlatl
                     Create lat/long environment map

              --lightprobe
                     Create lat/long environment map from a light probe

              --bumpslopes
                     Create a 6 channels bump-map with height, derivatives and square derivatives
                     from an height or a normal map

              --bumpformat %s
                     Specify the interpretation of a  3-channel  input  image  for  --bumpslopes:
                     "height", "normal" or "auto" (default).

       Color Management Options (OpenColorIO enabled)

              --colorconfig %s
                     Explicitly specify an OCIO configuration file

              --colorconvert %s %s
                     Apply  a  color  space conversion to the image. If the output color space is
                     not the same bit depth as input color space, it is  your  responsibility  to
                     set  the data format to the proper bit depth using the -d option.  (choices:
                     linear, default, rgb, RGB, sRGB, Rec709)

              --unpremult
                     Unpremultiply before color conversion,  then  premultiply  after  the  color
                     conversion.  You'll probably want to use this flag if your image contains an
                     alpha channel.

       Configuration Presets

              --prman
                     Use PRMan-safe settings for tile size, planarconfig, and metadata.

              --oiio Use OIIO-optimized settings for tile size, planarconfig, metadata.
