Watermark of the downloaded version of shared PDF files

Dear Forum Subscribers,

I have read nextcloud documentation and I gave a quick look to nextcloud apps, but I haven’t found a reference to how apply a custom “watermark” (background image, for example, with user name of the downloader and timestamp of downloading) to the downloaded version of a file shared by nextcloud (leaving unmodified the original version of downloaded file to let it available to other users for download).

Is it possible with current features with nextcloud ? Otherwise, there is a workaround to achieve these feature ?

Thanks in advances.

Im not a expert, but I guess you would have to hook into

to add an option to enable the watermark on download.
Add e.g. use

to add a watermark.

Then you would have to hook into the download JS code to execture the above watermark-code.
