exrmaketiled

exrmaketiled [options] infile outfile

Description

Read an OpenEXR image from infile, produce a tiled version of the image, and save 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.

-e x y

when a MIPMAP_LEVELS or RIPMAP_LEVELS image is produced, low-pass filtering takes samples outside the image’s data window. This requires extrapolating the image. Option -e specifies how the image is extrapolated horizontally and vertically (black/clamp/periodic/mirror, default is clamp).

-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/b44/b44a/dwaa/dwab, default is zip)

-v

verbose mode

-h, --help

print this message

--version

print version information

-p i

part number, default is 0
