帶有System.Drawing的輪廓文本？

Question

我有以下代碼。有一種簡單的方法可以對我正在寫的文本進行概述嗎？

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);

是的。相反抽繩，使用電話的順序如下：

• new GraphicsPath（創建一個空的GraphicsPath）
• GraphicsPath.AddString（在GraphicsPath對象現在表示該文本的輪廓）
• Graphics.DrawPath（畫輪廓的任何Pen你想要的）

如果您需要使用GraphicsPath.AddString一起Graphics.DrawString，你需要的字體大小轉換，becau se Graphics.DrawString預計「點大小」，而GraphicsPath.AddString預計「em大小」。轉換公式只是emSize = g.DpiY * pointSize/72。

下面是一個代碼示例：

// 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
