c# GIF picturebox

ImageAnimator 클래스를 이용해서 비트맵과 프레임변경 핸들러를 추가하면

ImageAnimator.UpdateFrames()를 통해 다음 프레임을 원하는대로 그리는 듯

투명도 되려나?

 

using System;
using System.Drawing;
using System.Windows.Forms;
 
namespace BackgroundWorkerTest
{
    public partial class SandGlass : Form
    {
        public SandGlass()
        {
            InitializeComponent();
            this.StartPosition = FormStartPosition.CenterScreen;
        }
 
        Bitmap bit;
        protected override void OnLoad(EventArgs e)
        {
            bit = new Bitmap("sandglass.gif");
            ImageAnimator.Animate(bit, new EventHandler(this.OnFrameChanged));
            base.OnLoad(e);
        }
        protected override void OnPaint(PaintEventArgs e)
        {
            ImageAnimator.UpdateFrames();
            Graphics g = pictureBox1.CreateGraphics();
            g.DrawImage(this.bit, new Point(0, 0));
            base.OnPaint(e);
        }
        private void OnFrameChanged(object sender, EventArgs e)
        {
            this.Invalidate();
        }
    }
}
