大纲文本与System.Drawing中？

问题描述

我有以下的code。有没有一种简单的方法把大纲上我写作文？

  VAR imageEn codeR = EN coder.Quality;
 VAR imageEn coderParameters =新恩coderParameters（1）;
 imageEn coderParameters.Param [0] =新恩coderParameter（imageEn codeR，100L）; VAR productImage = GetImageFromByteArray（myViewModel.ProductImage.DatabaseFile.FileContents）;
 VAR显卡= Graphics.FromImage（productImage）; VAR字体=新的字体（濑越脚本，24）;
 VAR刷= Brushes.Orange; VAR集装箱=​​新的Rectangle（myViewModel.ContainerX，myViewModel.ContainerY，myViewModel.ContainerWidth，myViewModel.ContainerHeight）; VAR的StringFormat =新的StringFormat {对齐= StringAlignment.Center，LineAlignment = StringAlignment.Center}; graphics.DrawString（customizationText，字体，画笔，容器的StringFormat）;
 

解决方案

是的。代替的DrawString的，使用呼叫的顺序如下：

• （创建一个空的的GraphicsPath ）


• （在的GraphicsPath 对象现在重新presents文字的轮廓）


• （吸入任何笔你想要的轮廓）

如果你需要使用 GraphicsPath.AddString 一起 Graphics.DrawString ，您需要将字体大小转换，因为 Graphics.DrawString 预计，点大小，而 GraphicsPath.AddString 预计，新兴市场的大小。其换算公式为根本 emSize = g.DpiY *的pointsize / 72 。

下面是一个code例如：

  //假设g为Graphics对象上要绘制文本
GraphicsPath的P =新的GraphicsPath（）;
p.AddString（
    我的文本字符串，//文字画
    FontFamily.GenericSansSerif，//或任何其他字体家族
    （INT）FontStyle.Regular，//字体样式（粗体，斜体等）
    g.DpiY * fontSize的/ 72 // EM大小
    新点（0,0），//位置，绘制文本
    新的StringFormat（））; //这里设置的选项（如居中对齐）
g.DrawPath（Pens.Black页）;
// + g.FillPath如果你想让它充满以及
 

I have the following code. Is there an easy way to put an outline on the text I am writing?

 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);

解决方案

Yes. Instead of DrawString, use the following sequence of calls:

• new GraphicsPath (creates an empty GraphicsPath)
• GraphicsPath.AddString (the GraphicsPath object now represents the outline of the text)
• Graphics.DrawPath (draws the outline in any Pen you want)

If you need to use GraphicsPath.AddString alongside Graphics.DrawString, you need to convert the font sizes, because Graphics.DrawString expects "point size" while GraphicsPath.AddString expects "em size". The conversion formula is simply emSize = g.DpiY * pointSize / 72.

Here's a code example:

// 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
