跟着 伍逸 老师学GDI+ 之SolidBrush,HatchBrush,LinearGradientBrush

跟着 伍逸 老师学GDI+

    最近在看伍逸 老师著的《C# 二维三维图形绘制工程实例宝典》，感觉这本书太经典了，心想一定要坚持把这本书看完，为了能勉励自己，特注册次博客。在此对伍逸老师表示由衷的感谢。

2.Brush的学习

  2.1 SolidBrush: 实心画刷

  2.2 HatchBrush: 阴影画刷

  2.3 LinerGradientBrush: 线性渐变画刷

 用法如下：（与书上同）

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
namespace _002Brush
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Brush brSolid = new SolidBrush(Color.Blue);
            Brush brHatch = new HatchBrush(HatchStyle.HorizontalBrick, Color.Red, Color.Yellow);
            Brush brGradient = new LinearGradientBrush(new Rectangle(0,0,200,200),Color.Black,Color.LightGray,45,false);
            g.FillRectangle(brGradient,10,10,200,200);
            g.FillEllipse(brHatch,200,200,150,190);
            g.FillPie(brSolid,0,0,300,300,285,75);
        }

    }
}

运行结果如下：
