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);
 }
