Hi Dear Sir/Madam,
The attached TIF image file had it’s Title, Subject, Authors, and copyright fields modified. After I use the official codes to remove the metadata, I noticed all four of these fields still contain data.
Here’s the test tif file.
Here’s the code we used https://docs.groupdocs.com/display/metadatanet/Add+or+Update+TIFF+tags+in+EXIF
We are using GroupDocs.Metadata v18.6
Btw, we have checked the “Camera serial number” field contained data , which was removed during the conversion process. Is it the expected behavoir, or this is a bug of GroupDocs.Metadata library?
Please have a check and let me know if you have any problem.
