Hey, I think i am using OIIO 2.0.5. I am emailling you the tif file having the issue The « bithdepth » variable was ’’uint8’’, i got the same error with ‘’uint16’’. Thanks. Liam.

Or only particular ones? Can you email me a particular TIFF file that exhibits this problem so I can try to reproduce? Also, do you know what the value of the 'bitdepth' variable is in this case? Which version of OIIO are you using? -- lg > On Jul 31, 2020, at 2:53 AM, MONSIEUR LIXM <[email protected]> wrote: > > > Hey, thanks for your answer, > So it is just a message that doesn?t stop the code BUT the written file is actually corrupted.(you can?t read it) > > I didn?t compiled OIIO myself , I am using a Python Wheel made by Fredrik Averpil. But this is the only error i had from now, if i convert an exr/hdr to png I don?t have any issue.
