       exrdisplay - displays an EXR image on the screen


       exrdisplay [options] imagefile


       exrdisplay is a simple still image viewer that optionally applies color
       transforms to OpenEXR images.


       A summary of the available options is included below.

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

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

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

       -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 image file.

       -h     Show summary of options.
