Description

The feature is like scrolling a screenshot on your mobile phone. For example, on Android. Besides, there is also a lot of software available for Windows, such as PicPick, FSCapture, and for Mac, such as xnip. Plus, there is another screenshot tool supporting Scrolling Screenshots on Mac, Shottr.

This feature is not well implemented. Here are a few things to consider:

  1. Is it possible to allow the use of the mouse wheel when selecting a screenshot area?
  2. Is there an interface that provides how many pixels a window scrolls at a time?
  3. Stitching of image content? Stitching algorithm for panoramic images?
  4. Scrolling direction: vertically, horizontally or both?

We can discuss here and offer some ideas and opinions.
