NAME
       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 cen-
	      ter. (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.
