       A summary of the available options is included below.

       -p     Displays the preview (thumbnail) image instead of the main image.

       -l  lx ly
              Displays level (lx, ly) of a tiled multiresolution image.

       -w     Displays all pixels in the data window, ignoring the display window.

       -a     Ignores the image's pixel aspect ratio, and does not scale the image to make the pixels square.

       -c  x  Loads only image channel x.

       -1     Sets exposure and knee sliders so that pixel value 0.0 becomes black, and 1.0 becomes white.

       -n     Normalizes the pixels so that the smallest value becomes 0.0 and the largest value becomes 1.0.

       -A     Same as -c A -1 (displays alpha).

       -Z     Same as -c Z -n (displays depth).

       -s     Swaps  the  image's  top  and  bottom  half,  then swaps the left and right half, so that the four
              corners of the image end up in the center. (Useful for checking the seams of  wrap-around  texture
              map images.)

       -u     Changing the exposure and knee controls continuously updates the on-screen image.

       -t  u  Use n parallel threads to read the imagefile.

       -h     Show summary of options.
