This piece of code only writes into the image somewhere in the picturebox. Hope this is what you have in mind.
这段代码只写入图片框中的某个图像。希望这是你的想法。
private void pictureBox1_MouseMove(object sender, MouseEventArgs e)
{
var p = new Pen(Color.Red, 5f);
var pbox = sender as PictureBox;
var area = (Bitmap)pbox.Image;
var g = Graphics.FromImage(area);
g.DrawEllipse(p, e.X, e.Y, 5, 5);
pbox.Image = area;
p.Dispose();
g.Dispose();
}
