Research direction

Start by reproducing the behavior with PhotoView inside an Android ViewPager, using an image larger than the view. Trace how scrolling at the image border transfers control to ViewPager. Done means the image can be scrolled back from its edge before ViewPager changes pages, or the behavior is exposed through a usable setting.

Description

I'm sorry if this has been asked before, I just haven't found anything relating this this.

So when PhotoView is in a ViewPager and the photo is scrollable (larger than the view size), the behavior is that whenever it reaches border, ViewPager takes over and starts to scroll pages. So when the user try to scroll the image and reaches the edge, they wants to scroll the other direction to view other part but at this point they can only move the whole ViewPager.

I'm wondering if there is a setting to allow a larger buffer after scrolling to the edge before ViewPager takes over?
