Description¶

Read an OpenEXR image from infile, produce a tiledversion 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

-fc

when a MIPMAP_LEVELS or RIPMAP_LEVELS imageis produced, image channel c will be resampledwithout low-pass filtering. This option canbe specified multiple times to disable low-passfiltering for multiple channels.

-exy

when a MIPMAP_LEVELS or RIPMAP_LEVELS imageis produced, low-pass filtering takes samplesoutside the image’s data window. This requiresextrapolating the image. Option -e specifieshow the image is extrapolated horizontally andvertically (black/clamp/periodic/mirror, defaultis clamp).

-txy

sets the tile size in the output image tox 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

-zx

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

-pi
