Question

我有以下代码。有没有简单的方法来概述我正在写的文字？

 var imageEncoder = Encoder.Quality;
 var imageEncoderParameters = new EncoderParameters(1);
 imageEncoderParameters.Param[0] = new EncoderParameter(imageEncoder, 100L);

 var productImage = GetImageFromByteArray(myViewModel.ProductImage.DatabaseFile.FileContents);
 var graphics = Graphics.FromImage(productImage);

 var font = new Font("Segoe Script", 24);
 var brush = Brushes.Orange;

 var container = new Rectangle(myViewModel.ContainerX, myViewModel.ContainerY,                                      myViewModel.ContainerWidth,                                              myViewModel.ContainerHeight);

 var stringFormat = new StringFormat {Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center};

 graphics.DrawString(customizationText, font, brush, container, stringFormat);

是。而不是DrawString，使用以下调用序列：

new GraphicsPath（创建一个空的GraphicsPath）
GraphicsPath.AddString（GraphicsPath对象现在代表文字的大纲）
Graphics.DrawPath（在您想要的任何Pen中绘制大纲）

如果您需要在GraphicsPath.AddString旁边使用Graphics.DrawString，则需要转换字体大小，因为Graphics.DrawString需要“磅值”，而GraphicsPath.AddString需要“大小” 。转换公式只是emSize = g.DpiY * pointSize / 72。

这是一个代码示例：

// assuming g is the Graphics object on which you want to draw the text
GraphicsPath p = new GraphicsPath(); 
p.AddString(
    "My Text String",             // text to draw
    FontFamily.GenericSansSerif,  // or any other font family
    (int) FontStyle.Regular,      // font style (bold, italic, etc.)
    g.DpiY * fontSize / 72,       // em size
    new Point(0, 0),              // location where to draw text
    new StringFormat());          // set options here (e.g. center alignment)
g.DrawPath(Pens.Black, p);
// + g.FillPath if you want it filled as well

使用System.Drawing概述文本？
