       -r top left height width
              Specifies the rectangle for region decode

       -T m   Reduced resolution  (mipmap)  decode  0:  Full  resolution  (default)  1:  1/2  res
              (down-sampled  from  full  res) 2: 1/4 res (native decode) 3: 1/8 res (down-sampled
              from 1/4 res) 4: 1/16 res (native decode)

              >4: 1/(2^m) res (down-sampled from 1/16 res)

       -O orientation
              0: No transformation (default) 1: Flip vertically  2:  Flip  horizontally  3:  Flip
              vertically  &  horizontally  4: Rotate 90 degrees CW 5: Rotate 90 degrees CW & flip
              vertically 6: Rotate 90 degrees CW & flip horizontally 7: Rotate 90  degrees  CW  &
              flip vert & horiz

       -s skip subbands
              Used  for  compressed domain transcoding 0: All subbands included (default) 1: Skip
              flexbits 2: Skip highpass 3: Skip highpass & lowpass (DC only)

       -a alpha decode
              0: Decode without alpha channel 1: Decode only alpha  channel  2:  Decode  image  &
              alpha (default)

       -p strength
              Post  processing  filter strength 0: None (default) 1: Light 2: Medium 3: Strong 4:
              Very strong

       -C     Suppress overlapping  boundary  macro  blocks  (Used  for  compressed  domain  tile
              extraction)

       -t     Display timing information

       -v     Display verbose decoder information

       Eg: JxrDecApp -i input.jxr -o output.bmp -c 0
