Hi Bob and Even,
(I'm copying Even's reply in this thread, and adding Darrell from
libjpeg-turbo after consulting with him).
Thank you for confirming libtiff does not support 16-bit JPEG.
This is very puzzling to me. I think it means that before I built libtiff
v4.6.0 with libjpeg-turbo v3.0.0, we must have had a patch or modification in
our libtiff version or our old libjpeg v6b version that allowed us to read the
16-bit linearRaw subimage in the TIFF file.
I just noticed this output in the libtiff configure script help
output.
--enable-jpeg12 enable libjpeg 8/12bit dual mode (not to be used
with libjpeg-turbo >= 2.2)
Did you enable the above option, although you are using libjpeg-turbo >= 2.2?
Bob
