Question

我正在使用Glyphs元素制作WPF文本编辑器。我有一个问题，即文本绘制不正确如图所示，我该如何解决这个问题？

有两个问题：

字母间的字距。
在字母和变音符号之间进行字距调整。

我通过GetKerningPairs函数解决的第一个问题。

我如何解决这个问题，也许我错了？

Answer 1

TrueType字体中不存在变音符号的字距，因此，您必须为变音符号定义自己的对列表，并给出相应的字距调整。在大多数字母中，变音符号是居中的，而其他字母则位于右侧。显然文本块执行上述操作。

Answer 2

正如@Codedom所说，你必须定义自己的列表，如下所示：

class Program
{
    static void Main(string[] args)
    {
        var list = new List<DiacriticsKerning>();
        list.Add(new DiacriticsKerning('א', 'ָ', HorizontalAlignment.Center, VerticalAlignment.None));
        list.Add(new DiacriticsKerning('ב', 'ָ', HorizontalAlignment.Center, VerticalAlignment.None));
        list.Add(new DiacriticsKerning('ג', 'ָ', HorizontalAlignment.Center, VerticalAlignment.None));
        list.Add(new DiacriticsKerning('ד', 'ָ', HorizontalAlignment.Right, VerticalAlignment.None));
        list.Add(new DiacriticsKerning('ה', 'ָ', HorizontalAlignment.Center, VerticalAlignment.None));
        list.Add(new DiacriticsKerning('ו', 'ָ', HorizontalAlignment.Center, VerticalAlignment.None));
        // ...
    }
}

struct DiacriticsKerning
{
    public DiacriticsKerning(char letter, char diacritics, HorizontalAlignment alignmentHorizontal, VerticalAlignment alignmentVertical)
    {
        Letters = letter;
        Diacritics = diacritics;
        HorizontalAlignment = alignmentHorizontal;
        VerticalAlignment = alignmentVertical;
    }

    char Letters;
    char Diacritics;
    HorizontalAlignment HorizontalAlignment;
    VerticalAlignment VerticalAlignment;
}

enum HorizontalAlignment { None, Center, Left, Right, }

enum VerticalAlignment { None, Center, Left, Right, }

WPF`Galphs`没有像TextBlock那样呈现文本
