心形画框 [英] heart shaped picturebox

问题描述

是否可以在C#中制作一个心形图片框? 我见过制作矩形和椭圆形的代码，但对制作心形区域一无所知.

Is it possible to make a heart shaped picturebox in c#? I have seen codes in making rectangle and ellipse but I don't have any idea on making a heart shaped region.

有什么主意吗?

推荐答案

这似乎可行:

public class HeartPictureBox : PictureBox {
    protected override void OnPaint(PaintEventArgs pe) {
        using (System.Drawing.Drawing2D.GraphicsPath path = new System.Drawing.Drawing2D.GraphicsPath()) {
            path.AddBezier(this.Width >> 1,
                            this.Height >> 2,
                            this.Width * 1.25f, 0f,
                            this.Width,
                            this.Height * 0.75f,
                            this.Width >> 1,
                            this.Height);
            path.AddBezier(this.Width >> 1,
                            this.Height >> 2,
                            -this.Width * .25f, 0f,
                            0f,
                            this.Height * 0.75f,
                            this.Width >> 1,
                            this.Height);

            this.Region = new Region(path);
        }
    }
}
