Scrolling does not work for scanned books, and zooming in/out is quite sensitive/jumpy (Logos 10)

There was an error rendering this rich post.

Dear Logos developers,

When trying to read my scanned books, I'm not able to scroll up / down; neither within the displayed page, nor from one page to the next or previous. The arrow buttons in the UI do work, but not scrolling the regular way using my laptop trackpad or arrow keys, which both do work fine in regular books and documents. When attempting to scroll up/down/left/right (within or between scanned book pages), a zoom in/out action happens instead, which feels a bit weird / counter-intuitive.

Also, the zooming action is very sensitive; it happens quite fast and jumpy, and I easily overshoot my target zoom size a few times before getting it right.

So both scrolling and zooming are a bit tedious to use, especially when needed for each new page I'm reading.

I've only noticed and tested this on the macOS version of Logos; don't know if it happens on Windows as well.

I assume that the scanned books feature is relatively new, and I'm very happy to have this feature for books that have not yet been OCR'ed. I believe it would very much improve usability of Logos 10 if these issues would be solved. Thank you very much for reading this bug report and I hope it's not too difficult to fix this bug!

With kind greetings,

An otherwise very content Logos user

I take it you are referring to the facsimile books which are simply photocopies of the books. These are actually a very old feature of Logos as a separate library but very new as independent cost items. The behavior you describe is inherent in page sized pictures. To solve the problems is a major undertaking, probably most effectively handled by OCR. As OCR is improving and becoming less expensive, it may eventually be done.

Well, OP is more successful than me. I can see the Overview thumbnails, but selecting any, a blank page. Maybe it's somewhere. Verbum latest; Mac latest.

I had this problem before and Mark had the answer.

Facsimiles work best in page mode in my experience.

Hmm .. no paged view in 3-dot menu. Legecian version.

I do also remember I bought just one facsimile before giving up.
