本文实例讲述了C#使用Matrix执行缩放的方法。分享给大家供大家参考。具体实现方法如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Drawing.Drawing2D;
namespace advanced_drawing
{
public partial class Form4 : Form
{
public Form4()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
//使用转换将单位设置为英寸
Graphics g=this.CreateGraphics();
Matrix matrix = new Matrix();
matrix.Scale(g.DpiX, g.DpiY);
g.Transform = matrix;
Font rulerFont = new Font("MS Sans Serif", 8.25f / g.DpiY);
Pen blackPen=new Pen(Color.Black,0);
float rulerFontHeight = rulerFont.GetHeight(g);
RectangleF rulerRect = new RectangleF(0, 0, 6.5f, rulerFontHeight * 1.5f);
g.DrawRectangle(blackPen, rulerRect.X, rulerRect.Y, rulerRect.Width, rulerRect.Height);
Brush brush = System.Drawing.Brushes.Red;
g.DrawString("zhuzhao", rulerFont, brush, rulerRect);
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
