Class CaptureScreenImage

Captures image pixels from screen or window.

public sealed class CaptureScreenImage : IDisposable
Remarks

This class is used by CaptureScreen, uiimage and uiimageFinder. Also you can use it directly. For example it can get pixels directly without copying to a Bitmap or array.

How to use:

  1. Create variable.
  2. Call Capture.
  3. Call other functions to get result in various formats.
  4. If need, repeat 2-3 (for example when waiting for image).
  5. Dispose (important).

Pixel format: Format32bppArgb, alpha 0xff.

Examples
var w = wnd.find("LibreAutomate").Child("document");

using var c = new CaptureScreenImage();
if (!c.Capture(w, new(0, 0, 200, 200))) return;
using var b = c.ToBitmap();

var f = folders.Temp + "test.png"; b.Save(f); run.it(f);
