Create screenshot from region

[parkpaya]

Short summary
Trying to take screenshot on specific region of screen but still can't figure how

Detailed question
What expected

const {  Region ,ImageWriter,ScreenAction} = require("@nut-tree/nut-js");
ImageWriter.store(new ScreenAction.grabScreenRegion(new Region(x,y,w,h)),"myImage.png");

but get an error

OK, I figure it out now.

const regionCapture = async (selectedRegion,outputFilename) => {
  var regionImage =  await screen.vision.grabScreenRegion(selectedRegion);
  screen.vision.saveImage(regionImage,outputFilename);
};

regionCapture(new Region(x,y,w,h),"myImage.png");

Hi @parkpaya,

functionality to capture screen regions is indeed missing on the screen public interface.
Since you already dug into it, want to contribute? Would be more than happy about a PR

I recently worked with the workaround proposed by @parkpaya. It works great. 👍 It's a little ugly, because you have to grab deep into the dists for the import but it works.

As I assume, I'm not the only person who requires that feature, I'll reopen this issue and alter the public api as you suggested @s1hofmann.
