图片框中的圆角边缘C#

Question

如何在图片框控件中舍入边缘.我想获得像椭圆这样的角度,但我不知道该怎么做.我用C#.谢谢!

Answer 1

把表格上1个图片框,也写这样的代码,你可以改变宽度的旁边的负号和高度以获得最好的结果

 System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();
            gp.AddEllipse(0, 0, pictureBox1.Width - 3, pictureBox1.Height - 3);
            Region rg = new Region(gp);
            pictureBox1.Region = rg;

Answer 2

是的,没问题,您可以使用Region属性为控件赋予任意形状.在项目中添加一个新类并粘贴下面显示的代码.编译.将新控件从工具箱顶部拖放到表单上.

using System;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Windows.Forms;

class OvalPictureBox : PictureBox {
    public OvalPictureBox() {
        this.BackColor = Color.DarkGray;
    }
    protected override void OnResize(EventArgs e) {
        base.OnResize(e);
        using (var gp = new GraphicsPath()) {
            gp.AddEllipse(new Rectangle(0, 0, this.Width-1, this.Height-1));
            this.Region = new Region(gp);
        }
    }
}

圆边的圆形边角？

如果是这样,请查看http://social.msdn.microsoft.com/forums/en-US/winforms/thread/603084bb-1aae-45d1-84ae-8544386d58fd

Rectangle r = new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height);
System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();
int d = 50;
gp.AddArc(r.X, r.Y, d, d, 180, 90);
gp.AddArc(r.X + r.Width - d, r.Y, d, d, 270, 90);
gp.AddArc(r.X + r.Width - d, r.Y + r.Height - d, d, d, 0, 90);
gp.AddArc(r.X, r.Y + r.Height - d, d, d, 90, 90);
pictureBox1.Region = new Region(gp);
