       exrdisplay - displays an EXR image on the screen

SYNOPSIS

       exrdisplay [options] imagefile

DESCRIPTION

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

OPTIONS

       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 image file.

       -h     Show summary of options.
