EXRMAKETILED(1) 					      General Commands Manual						   EXRMAKETILED(1)

NAME

       exrmaketiled - for generating tiled and rip/mipmapped images.

SYNOPSIS

       exrmaketiled [options] infile outfile

DESCRIPTION

       This manual page documents briefly the exrmaketiled command.  This manual page was written for the Debian distribution because the original
       program does not have a manual page.

       exrmaketiled reads an OpenEXR image from infile, produces a tiled version of the image, and saves the result in outfile.

OPTIONS

       -o     produces a ONE_LEVEL image (default)

       -m     produces a MIPMAP_LEVELS multiresolution image

       -r     produces a RIPMAP_LEVELS multiresolution image

       -f c   when a MIPMAP_LEVELS or RIPMAP_LEVELS image is produced, image channel c will be resampled without low-pass filtering.  This  option
	      can be specified multiple times to disable low-pass filtering for multiple channels.

       -t x y sets the tile size in the output image to x by y pixels (default is 64 by 64)

       -d     sets level size rounding to ROUND_DOWN (default)

       -u     sets level size rounding to ROUND_UP

       -z x   sets the data compression method to x (none/rle/zip/piz/pxr24, default is zip)

       -v     verbose mode

       -h     prints these options

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.
