一般Graphics都是通过控件比如Panel，PictureBox来进行绘制的，
PictureBox pb= new PictureBox();
pb.Paint += new System.Windows.Forms.PaintEventHandler(this.Test_Paint);
void Test_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
g.DrawImage(....);
g.DrawLine(...);
}
PictureBox pb= new PictureBox();
pb.Paint += new System.Windows.Forms.PaintEventHandler(this.Test_Paint);
void Test_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
g.DrawImage(....);
g.DrawLine(...);
}
vb.net 中通过Graphic怎么在原有的图片上绘制DrawLines
