ebook reader: page not scroll to top after leaf through (prev or next)

[UnnamedHero]

It is very annoying to scroll to the top of a page every time after swithing to next or prevoius page.

Reader is designed for reading full pages, without scrolling. In what context do you have to scroll the page up after turning a page. Also, which renderer (Epub, PDF, CBx) does this apply to?

[UnnamedHero]

This applies to pdf renderer. A PDF page renders with a tiny font in fit-to-screen mode. It is very uncomfortable to read even on 24" monitor @ 1920x1080.

Try the following patch:

diff --git a/files_reader/vendor/pdfjs/pdf.reader.js b/files_reader/vendor/pdfjs/pdf.reader.js

BTW, the following screen dump shows Reader with a double-page spread at 1920*1200. Quite readable I'd say, especially at 24". Make sure to use the full screen function to use the maximum amount of screen real estate.

This will be an option in the next release:

The option will be disabled by default.
