       private void Form1_MouseUp(object sender, MouseEventArgs e)
        {
            Graphics nGraphics=this.CreateGraphics();
            nGraphics.TranslateTransform(100.0F, 100.0F);
            nGraphics.DrawImage(pictureBox1.Image, 0, 0);            nGraphics.RotateTransform(10.0F);
            nGraphics.DrawImage(pictureBox1.Image,0, 0);            nGraphics.RotateTransform(10.0F);
            nGraphics.DrawImage(pictureBox1.Image, 0, 0);            nGraphics.RotateTransform(10.0F);
            nGraphics.DrawImage(pictureBox1.Image, 0, 0);            nGraphics.Dispose();        }http://www.mybuffet.cn

using (Bitmap bmp = new Bitmap(@"d:\A.bmp")) 
            { 
                Graphics g = this.CreateGraphics(); 
                Rectangle rect = new Rectangle(0, 0, 100, 100);  
                bmp.RotateFlip(RotateFlipType.RotateNoneFlipX); 
                g.DrawImage(bmp, rect);
