I am using OIIO 1.6.13 although using a custom build, so there are many
reasons why this could fail for me.
It would be good to know if what I'm trying is known to be (or not be)
working, if this has been tried before, or if you think this is just plain
foolish for some reason.
tiffinfo, which links with the same version of libtiff and libjpeg as
maketx reports:
tiffinfo -v
LIBTIFF, Version 3.9.4
My test image is a 4K half-float linear .exr:
oiiotool -v -info test.exr
Reading test.exr
test.exr : 4096 x 4096, 3 channel, half openexr
channel list: R, G, B
oiio:ColorSpace: "Linear"
compression: "zip"
a_color_render_transform: 0
a_colorspace: 1
a_format: -1
a_res: 0
dwaVersion: 200
machine: "xlimepuma.anim.dreamworks.com"
PixelAspectRatio: 1
screenWindowCenter: 0 0
screenWindowWidth: 1
