C# GDI+ 文字操作

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);
        }
