Motivation
I self-host my own Nextcloud instance. I'm a student and I annotate PDFs
(exercise sheets, textbooks) daily on a tablet with a stylus.
One feature I rely on heavily is the ability to select a region
of the PDF — for example an exercise statement — and paste it
further down in the same note, so I can write my solution
directly below without having to scroll up and down constantly.
This is the single feature that is preventing me from switching
fully to Saber. I currently have to use a proprietary app with
a cloud I don't control, only because of this missing capability.
Expected behavior
- User selects the rectangle/lasso selection tool
- User draws a selection around a region of the PDF
- User taps "Copy" → the region is captured as an image
- User navigates to another page and taps "Paste" → the image is
inserted and can be repositioned
Similar feature in
Notewise (Android), GoodNotes (iOS/Android)

Solution
I have no Flutter experience and no technical background,
but after discussing with an AI assistant, it suggested that
a possible approach would be to render the selected region
of the PDF background as a bitmap image using the existing
PDF renderer, then insert it as a regular image element
that can be repositioned — similar to how a screenshot
of the selection would work internally.
I'm not in a position to validate or discuss this technically,
but I wanted to mention it in case it helps frame the request.
Alternatives
Using an external screenshot tool and importing the image manually.
It works but completely breaks the note-taking flow.
Saber version
v1.34.1 Google Play (134011)
Device
- Device: Samsung Tab S9
- OS: One UI 9.0, Android 16
Anything else?
