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); }
