Is the .tiff structure in Matlab 2020a and Matlab 2020b/2021 different?

Dear all,

I have got the following problem: I wrote a Matlab-Scritp that saves my processed image as a tiff file.

Afterwards I want to load it into a different sofware.

If I run my script with Matlab 2020a, everything works fine. Using any older Matlab version, the other software is not able to read it anymore.

Do you know whether there is anything changed during the version in the way the tiff file is saved?

How can I save my tiff file using the newest Matlab version getting the "older tiff-format"?

Thank you for your help!

MATLAB has several ways to write tiff file, imwrite, print, Tiff class, etc... Which function are upu using and what type the data image?

[Emma]

I am using imwrite to save a uint16 image:

imwrite(resulting_image,filename_new,'Resolution', 72, 'Compression', 'none');

[Bruno Luong]

After saving it, can you run this command

t=Tiff(filename_new)

on both MATLAB versions and see if there is a difference?

[Emma]

Yes, I checked and there is no difference at all.

[Bruno Luong]

Can you redo the same but check

t.getVersion

[Emma]

Yes, now I see differences:

For Matlab 2020a I get:

'LIBTIFF, Version 4.0.10

For Matlab 2021b I get:

'LIBTIFF, Version 4.2.0

Copyright (c) 1988-1996 Sam Leffler

Copyright (c) 1991-1996 Silicon Graphics, Inc.'

Do you know where exactly the differences in the way my tiff file is saved lays?

Thank you a lot for your help!

It seems imwrite Matlab 2021b use an update tiff library that your other SW cannot deal with.

I'm afraid you are stuck with the older MATLAB version, unless some authority person in TMW know a work around.

Hi!

I understand that you've been using a MATLAB script with version R2020a to process images and save them as TIFF files, and this works well when you import the images into another program. However, it seems that you're encountering issues when you use newer versions of MATLAB, like R2020b or R2021a; the other software can't read the images.

It appears that the issue you're experiencing may be related to the version of LibTIFF that MATLAB is using. In MATLAB R2020a, the supported LibTIFF version is 4.0.10, while in MATLAB R2020b and R2021a, the version has been updated to 4.1.0. You can confirm this information through the following MATLAB documentation links:

For R2020a: https://www.mathworks.com/help/releases/R2020a/matlab/ref/tiff.html#:~:text=MATLAB%C2%AE%20supports%20LibTIFF%20version%204.0.10

For R2020b: https://www.mathworks.com/help/releases/R2020b/matlab/ref/tiff.html#:~:text=MATLAB%C2%AE%20supports%20LibTIFF%20version%204.1.0.

MATLAB typically binds to a specific version of LibTIFF for each release and doesn't offer the flexibility to change it. A practical approach would be to identify the versions of LibTIFF that are supported by the other software you're using and match it with the corresponding MATLAB version.

If the information provided doesn't quite solve your issue, or if there's something I've misunderstood, you could reach out to MathWorks using the following link.
