<div>
public void createGif()
{
Bitmap bmp = new Bitmap(100, 100);
Graphics g = Graphics.FromImage(bmp);
Font f = new Font("arial", 11f);
Brush b = Brushes.Blue;
string txt = "1";
SizeF sz = g.MeasureString(txt, f); //用指定的字符串测量大小
g.Clear(Color.WhiteSmoke); //把画布用某个颜色填充
g.DrawString(txt, f, b, sz.Width / 2, sz.Height / 2);
g.Flush();
//(The following code create a starting frame from bmp)
GifImage.GifAnimation gif = new GifImage.GifAnimation(bmp,
GifImage.GraphicControlExt.Default);
//(Set this property otherwise the animation will not play circularly)循环
gif.Application = GifImage.ApplicationExt.Default;
//(Use global color table only, set this option will greatly decrease the size of output file)
gif.UseGlobalColorTableOnly = true;
for (int i = 1; i < 36; ++i)
{
txt = i.ToString();
g.Clear(Color.WhiteSmoke);
g.DrawString(txt, f, b, sz.Width / 2, sz.Height / 2);
g.Flush();
//(Create a frame from bitmap)
gif.AddFrame(bmp);
}
f.Dispose();
g.Dispose();
bmp.Dispose();
FileStream fs = new FileStream(@"E:\vmlinux\GifImage.gif", FileMode.Create);
//(Write animation to GifImage.gif)
gif.Save(fs);
fs.Close();
}
