C#使用Matrix执行缩放的方法
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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
usingSystem.Drawing.Drawing2D;
namespaceadvanced_drawing
{
publicpartialclassForm4:Form
{
publicForm4()
{
InitializeComponent();
}
privatevoidbutton1_Click(objectsender,EventArgse)
{
//使用转换将单位设置为英寸
Graphicsg=this.CreateGraphics();
Matrixmatrix=newMatrix();
matrix.Scale(g.DpiX,g.DpiY);
g.Transform=matrix;
FontrulerFont=newFont("MSSansSerif",8.25f/g.DpiY);
PenblackPen=newPen(Color.Black,0);
floatrulerFontHeight=rulerFont.GetHeight(g);
RectangleFrulerRect=newRectangleF(0,0,6.5f,rulerFontHeight*1.5f);
g.DrawRectangle(blackPen,rulerRect.X,rulerRect.Y,rulerRect.Width,rulerRect.Height);
Brushbrush=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。
