How to remove Tag 269 DocumentName from Tiff file

[LongTran]

Hello,

When I use Linux command tiffinfo to display the information about a tif document, there is a tag called
DocumentName.
This tag shows the absolute pathname of the current tiff file

I would like to remove this tag

I have tried the command convert… +set but I think I set up the parameters incorrectly and the result still shows the DocumentName

For example

convert +set "DocumentName" /tmp/in.tif /tmp/out.tif

I have tried this but it does not work either

convert +set "EXIF:DocumentName" /tmp/in.tif /tmp/out.tif

Any pointers, URL links to documents or examples would be greatly appreciated.

I don't think you can do that with IM. But you should with EXIFTOOL.

I tried EXIFTOOL and it does what I need - add, modify, remove tags.
Thank you for your help.
