I had a question about the SHA1 hashes in OIIO. If I run maketx on a random
image so that I get out.tx, and then for that same out.tx I do the
following commands which report different hashes:
$ oiiotool --info -v out.tx | grep SHA
oiio:SHA-1: "2B93D027BA312B5A4113F7A2B1216967F1822E50"
$ oiiotool --hash out.tx
out.tx : 888 x 320, 3 channel, uint8 tiff (+mipmap)
SHA-1: A3BE1671AEF29389C350F84737873D972A427F51
Are these two hashes supposed to be different? If so, what are the
differences in the underlying data that causes a different hash?
Thanks in advance for the clarification!
