如何定义图片框坐标

Question

我正在尝试在图片框的另一张图片上绘制一张图片。它们的尺寸相同（125X150）。当我在图片框的[0,0]点绘制第二张图片时，两张图片没有对齐。这是我的代码：

        pictureBox1.Image = Image.FromFile("picture\\faces\\face3.png");

        Bitmap bmp = new Bitmap(pictureBox1.Image);
        Graphics g = Graphics.FromImage(bmp);
        g.DrawImage(new Bitmap("picture\\faces\\eyebow1.png"), new Point(0, 0));
        g.Dispose();
        pictureBox1.Image = bmp;

Answer 1

我自己弄清楚了。虽然我不知道为什么：

        pictureBox1.Image = Image.FromFile("picture\\faces\\face3.png");

        Bitmap bmp = new Bitmap(pictureBox1.Image);
        Console.WriteLine(bmp.Width);
        Graphics g = Graphics.FromImage(bmp);

        pictureBox1.Image = Image.FromFile("picture\\faces\\eyebow1.png");
        g.DrawImage(new Bitmap(pictureBox1.Image), new Point(0, 0));

        g.Dispose();
        pictureBox1.Image = bmp;
