C#动画处理，gif老是无法正常显示
在做图片软件的时候，遇到gif无法正常显示，这是显示窗体的代码
程序代码：using System.Drawing;
using System.Windows.Forms;
using System;
namespace WindowsFormsApplication1
{
class F:Form
{
Bitmap bitmap;
//是否为动画，用于ImageAnimator.Stop判断
bool IsGif = false;
private void OnFrameChanged(object o, EventArgs e)
{
ImageAnimator.UpdateFrames();
this.CreateGraphics().DrawImage(this.bitmap, 0, 0);
}
//传入图片
public void ShowImg(Bitmap bt)
{
bitmap = bt;
//窗体设置
InitializeComponent();
this.ShowDialog();
}
//绘制
protected override void OnPaint(PaintEventArgs e)
{
if (ImageAnimator.CanAnimate(bitmap))
{
//静态图片处理
ImageAnimator.Animate(bitmap, new EventHandler(this.OnFrameChanged));
IsGif = true;
}
else
{
//动态图片处理
this.CreateGraphics().DrawImage(this.bitmap, 0, 0);
IsGif = false;
}
}
private void InitializeComponent()
{
this.SuspendLayout();
//
// F
//
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
this.Width = bitmap.Width + 16;
this.Height = bitmap.Height + 38;
this.ShowIcon = false;
this.MaximizeBox = false;
// this.ClientSize = new System.Drawing.Size(284, 262);
this.Name = "F";
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.F_FormClosing);
this.ResumeLayout(false);
}
//关闭窗体时，释放资源
private void F_FormClosing(object sender, FormClosingEventArgs e)
{
if (IsGif)
ImageAnimator.StopAnimate(bitmap, new EventHandler(this.OnFrameChanged));
bitmap.Dispose();
}
}
}
