WPF：字形从右到左的文本呈现

我想使用Glyph来呈现从右到左的语言文本（例如阿拉伯语或混合英语和阿拉伯语）。

我正在使用此代码：

Typeface typeface = new Typeface(new FontFamily("Arial"), FontStyles.Italic, FontWeights.Normal, FontStretches.Normal); GlyphTypeface glyphTypeface; if (!typeface.TryGetGlyphTypeface(out glyphTypeface)) throw new InvalidOperationException("No glyphtypeface found"); string text = "Hello , سلام"; double size = 40; ushort[] glyphIndexes = new ushort[text.Length]; double[] advanceWidths = new double[text.Length]; double totalWidth = 0; for (int n = 0; n < text.Length; n++) { ushort glyphIndex = glyphTypeface.CharacterToGlyphMap[text[n]]; glyphIndexes[n] = glyphIndex; double width = glyphTypeface.AdvanceWidths[glyphIndex] * size; advanceWidths[n] = width; totalWidth += width; } Point origin = new Point(50, 50); GlyphRun glyphRun = new GlyphRun(glyphTypeface, 0, false, size, glyphIndexes, origin, advanceWidths, null, null, null, null, null, null); dc.DrawGlyphRun(Brushes.Black, glyphRun); 

但问题是阿拉伯字符是分开显示的，如下所示：

  Hello , س ل ا م 

请指导我

更新：

这是Obfuscate解决方案的结果：

问题是阿拉伯字母是单独呈现的。

但这就是我想要的：

尝试使用不同的CultureInfo格式化两个字符串

 string x = string.Format(new CultureInfo("en-US"), "{0}" ,text1); string y = string.Format(new CultureInfo("ar-SA"), "{0}", text2); 

更新了解决方案…… xaml有一个Canvas。

MainWindow（WPF）

  public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); Size s = new Size(200,50); GlyphElement gex = new GlyphElement( string.Format(new CultureInfo("en-US"), "{0}", "Hello"), Brushes.Red, s); MyCanvas.Children.Add(gex); Canvas.SetTop(gex, 10); Canvas.SetLeft(gex, 10); GlyphElement gey = new GlyphElement( string.Format(new CultureInfo("ar-SA"), "{0}", "سلام"), Brushes.Black, s); MyCanvas.Children.Add(gey); Canvas.SetTop(gey, 100); Canvas.SetLeft(gey, 10); } } 

将GlyphElement包装在FrameworkElement中

  class GlyphElement : FrameworkElement { private GlyphRunner gr; public GlyphElement(string text, Brush br, Size size) { gr = new GlyphRunner(text, br, size); } protected override Visual GetVisualChild(int index) { return gr; } protected override int VisualChildrenCount { get { return 1; } } } 

将GlyphRunner包装在DrawingVisual中

  public class GlyphRunner : DrawingVisual { public GlyphRunner(string text, Brush bc, Size size) { DrawingImage di = CreateGlyph(text, new Point(0, 0), bc); using (DrawingContext dc = RenderOpen()) { dc.DrawImage(di,new Rect(size)); } } // small updates to your code follow public DrawingImage CreateGlyph(string text, Point origin, Brush bc) { Typeface typeface = new Typeface(new FontFamily("Arial"), FontStyles.Normal, FontWeights.Normal, FontStretches.Normal); GlyphTypeface glyphTypeface; if (!typeface.TryGetGlyphTypeface(out glyphTypeface)) throw new InvalidOperationException("No glyphtypeface found"); ushort[] glyphIndexes = new ushort[text.Length]; double[] advanceWidths = new double[text.Length]; double totalWidth = 0; for (int n = 0; n < text.Length; n++) { ushort glyphIndex = glyphTypeface.CharacterToGlyphMap[text[n]]; glyphIndexes[n] = glyphIndex; double width = glyphTypeface.AdvanceWidths[glyphIndex]; advanceWidths[n] = width; totalWidth += width; } float ppd = (float)VisualTreeHelper.GetDpi(this).PixelsPerDip; GlyphRun gr = new GlyphRun(glyphTypeface, 0, false, 1.0, ppd, glyphIndexes, origin, advanceWidths, null, null, null, null, null, null); GlyphRunDrawing glyphRunDrawing = new GlyphRunDrawing(bc, gr); return new DrawingImage(glyphRunDrawing); } }
