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);
}
