使用System.Drawing概述文本？

Question

我有以下代码.有没有一种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);

Answer 1

是.而不是DrawString,使用以下调用序列:

• new GraphicsPath(创建一个空的GraphicsPath)
• GraphicsPath.AddString(该GraphicsPath对象现在代表文本的轮廓)
• Graphics.DrawPath(以任何Pen你想要的方式绘制轮廓)

如果你需要使用GraphicsPath.AddString旁边Graphics.DrawString,你需要的字体大小转换,由于Graphics.DrawString期望"字号",而GraphicsPath.AddString希望"EM大小".转换公式很简单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
