[FEATURE REQUEST] Make borders snap to edges of scan in Editing mode.

[thisisartman]

Is your feature request related to a problem? Please describe. When editing a scan, the borders are very sluggish to drag and a bit difficult to move around to fit the shape of the document.

Describe the solution you'd like Ability to drag the handles faster, and have them snap to the corners wherever possible to make it easier to get the document cropped.

Describe alternatives you've considered The only other alternative I see as of now is to just make the handle dragging easier. Until we get the edge management sorted out.

Additional context A comparison between how OSS Document Scanner handles editing vs how Microsoft Lens handles it.

@thisisartman thanks for the report. What MSLens does is really nice thought i dont really know how they do that .

Now about the real issue here which is the sluggishness. It is really obvious in your video. Though i cant reproduce it here. What s your phone/android version? can you share the image you are testing with?

What s your phone/android version?

My bad. I forgot to mention this. Crdroid 10.9 (Android 14) custom ROM on a Poco F4 5G.

Also, sure... Adding image here:

@thisisartman thanks. I figured it out. It is not really sluggishness. It happens when the "corners" are too close the view borders. Then it keeps on "blocking". If you move the corners a bit out of the borders, it should not be sluggish anymore. Will try to fix it

@thisisartman can you try latest version and tell if it is better?
