.net Framework 4.8 기반에 Image viewer User control입니다. ImageViewport를 생성하여 Panel과 같은 Controls에 Add 한 후 사용하는 방식으로 되어 있습니다. 이 Control의 사용 범위는 이미지 file의 Viewer / Camera 이미지 Viewer에 쓰일 수 있습니다. 좀 더 응용할 수 있는 방법이 있다면 https://luciodev.tistory.com/12 블로그에 댓글이나 방명록에 남겨주시면 적극 반영하도록 하겠습니다.
Update 내용 OpenCV Video capture 추가 적용
