[C#/WINFORM] Graphics 클래스 : CopyFromScreen 메소드를 사용해 화면 캡처하기

■ Graphics 클래스의 CopyFromScreen 메소드를 사용해 화면을 캡처하는 방법을 보여준다.

▶ Graphics 클래스 : CopyFromScreen 메소드를 사용해 화면 캡처하기 예제 (C#)


using System.Drawing;

Bitmap bitmap = CaptureScreen(new Rectangle(0, 0, 1024, 768)); // 화면 단위

using System.Drawing;

Bitmap bitmap = CaptureScreen(new Rectangle(0, 0, 1024, 768)); // 화면 단위
