C#常用GDI+文字操作汇总

本文实例汇总了C#常用GDI+文字操作，包含了文字的投影、倒影、旋转等常见的效果，在进行C#应用程序开发中有不错的实用价值。分享给大家供大家参考之用。具体如下：

一、投影文字

private void Form1_Paint(object sender, PaintEventArgs e)

{

  //投影文字

  Graphics g = this.CreateGraphics();

  //设置文本输出质量

  g.TextRenderingHint = TextRenderingHint.ClearTypeGridFit;

  g.SmoothingMode = SmoothingMode.AntiAlias;

  Font newFont = new Font("Times New Roman", 48);

  Matrix matrix = new Matrix();

  //投射

  matrix.Shear(-1.5f, 0.0f);

  //缩放

  matrix.Scale(1, 0.5f);

  //平移

  matrix.Translate(130, 88);

  //对绘图平面实施坐标变换、、

  g.Transform = matrix;

  SolidBrush grayBrush = new SolidBrush(Color.Gray);

  SolidBrush colorBrush = new SolidBrush(Color.BlueViolet);

  string text = "MINGRISOFT";

  //绘制阴影

  g.DrawString(text, newFont, grayBrush, new PointF(0, 30));

  g.ResetTransform();

  //绘制前景

  g.DrawString(text, newFont, colorBrush, new PointF(0, 30));

}

二、倒影文字

private void Form1_Paint(object sender, PaintEventArgs e)

{

  //倒影文字

  Brush backBrush = Brushes.Gray;

  Brush foreBrush = Brushes.Black;

  Font font = new Font("幼圆", Convert.ToInt16(40), FontStyle.Regular);

  Graphics g = this.CreateGraphics();

  string text = "MINGRISOFT";

  SizeF size = g.MeasureString(text, font);

  int posX = (this.Width - Convert.ToInt16(size.Width)) / 2;

  int posY = (this.Height - Convert.ToInt16(size.Height)) / 2;

  g.TranslateTransform(posX, posY);

  int ascent = font.FontFamily.GetCellAscent(font.Style);

  int spacing = font.FontFamily.GetLineSpacing(font.Style);

  int lineHeight = System.Convert.ToInt16(font.GetHeight(g));

  int height = lineHeight * ascent / spacing;

  GraphicsState state = g.Save();

  g.ScaleTransform(1, -1.0F);

  g.DrawString(text, font, backBrush, 0, -height);

  g.Restore(state);

  g.DrawString(text, font, foreBrush, 0, -height);

}

三、文字填充线条

private void Form1_Paint(object sender, PaintEventArgs e)

{

  //使用图像填充文字线条

  TextureBrush brush = new TextureBrush(Image.FromFile(Application.StartupPath + "\\花.jpg"));

  Graphics g = e.Graphics;

  g.DrawString("MINGRISOFT", new Font("隶书", 60), brush, new PointF(0, 0)); 

}

四、旋转文字

private void Form1_Paint(object sender, PaintEventArgs e)

{

  //旋转显示文字

  Graphics g = e.Graphics;

  g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

  for (int i = 0; i <= 360; i += 10)

  {  

 //平移Graphics对象到窗体中心

 g.TranslateTransform(this.Width / 2, this.Height / 2);

 //设置Graphics对象的输出角度

 g.RotateTransform(i);

 //设置文字填充颜色

 Brush brush = Brushes.DarkViolet;

 //旋转显示文字

 g.DrawString("......MINGRISOFT", new Font("Lucida Console", 11f), brush, 0, 0);

 //恢复全局变换矩阵

 g.ResetTransform();

  }

}

五、印版文字

private void Form1_Paint(object sender, PaintEventArgs e)

{

  //印版文字

  int i = 0;

  Brush backBrush = Brushes.Black;

  Brush foreBrush = Brushes.Violet;

  Font font = new Font("Times New Roman", System.Convert.ToInt16(40), FontStyle.Regular);

  Graphics g = this.CreateGraphics();

  g.Clear(Color.White);

  string text = "MINGRISOFT";

  SizeF size = g.MeasureString(text, font);

  Single posX = (this.Width - Convert.ToInt16(size.Width)) / 2;

  Single posY = (this.Height - Convert.ToInt16(size.Height)) / 3;

  while (i < Convert.ToInt16(20))

  {

 g.DrawString(text, font, backBrush, posX - i, posY + i);

 i = i + 1;

  }

  g.DrawString(text, font, foreBrush, posX, posY);

}

相信本文所述实例对大家的C#程序设计有一定的帮助。
