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。
