TIFF without thumbnail

[IwoMk]

Hello, please can you save TIFF without preview.

When I want to save an image in *.TIF, it is saved with preview. I can't use this format because of the limitations of my project. I am limited to uncompressed TIFF without preview.

Also, the verification application tells me that the file is not valid after saving. Please change the saving mechanism to make the TIFF file valid according to the Open Preservation Foundation (JHOVE). Thank you very much in advance.

I am attaching printscreen - the output from Jhove: 0328.tif is the original TIFF file and 0328nomacs.tif is saved in Nomacs with nocompression.

Hello @IwoMk, are you certain that the thumbnail is the cause, or is it a speculation? I've read the validity section of the link you provided, and I did not find anything related to the thumbnail. Does your tool report which validity rule this image violates?

[IwoMk]

Hello, no. I don't know.

It's possible there are two problems:

1. The input file is without thumbnail, but after saving in Nomacs it is with thumbnail. I need it to be without thumbnail again.
2. The input file is valid, but after saving in Nomacs it is not valid.

I have a colleague, he knows JHOVE better. I'll try to ask him if he can identify the problem with validity.

Reproduced with nomacs 3.12 on Ubuntu 22.04.

The problem seems to be the thumbnail IFD missing some tags. But that IFD should be an EXIF IFD, I'm still unsure if this is a bug of nomacs or JHOVE.

[IwoMk]

@leejuyuu Would it be possible to make a checkbox in settings Nomacs to not create a thumbnail for the tiff file?

If it could be saved file without a thumbnail, we'll see so if the bug in JHOVE is removed and a file is valid.

I saved the tiff file in Nomacs and then saved it again in XnView Classic, result:

When I save the file only in XnView Classic, the file is valid. Does that help?

(Xnview writes its own EXIF field Software, normally I can't use it.)

Because your goal is to make the resulting tiff file valid instead of removing the thumbnail, it feels more straightforward to fix the validity instead of creating a new feature to work around this.

I think the key here is to find a way (or some other software) to write EXIF thumbnails to tiff files in a way that is valid for JHOVE.
