C# 在WPF中转换时，文本会模糊

我正在使用DrawingContext.DrawText和DrawingContext.PushTransfrom在WPF的可视层上创建旋转文本，但如下图所示，旋转文本在图像的某些区域相当模糊

我有什么办法可以改进这一点吗？文本使用Arial字体

public class BeamTextDrawing : FrameworkElement
{
    private readonly VisualCollection _visuals;
    public BeamTextDrawing(double scale)
    {
        if (scale <= 0)
        {
            scale = 1;
        }
        var typeface = Settings.BeamTextTypeface;
        var cultureinfo = Settings.CultureInfo;
        var flowdirection = Settings.FlowDirection;
        var textsize = Settings.BeamTextSize / scale;
        var beamtextcolor = Settings.InPlanBeamTextColor;

        _visuals = new VisualCollection(this);

        foreach (var beam in Building.BeamsInTheElevation)
        {
            var drawingVisual = new DrawingVisual();
            using (var dc = drawingVisual.RenderOpen())
            {
                var text = Convert.ToString(beam.Section.Id);
                //text = scale.ToString();
                var ft = new FormattedText(text, cultureinfo, flowdirection,
                                            typeface, textsize, beamtextcolor)
                {
                    TextAlignment = TextAlignment.Center
                };

                var x1 = beam.ConnectivityLine.I.X;
                var y1 = beam.ConnectivityLine.I.Y;
                var x2 = beam.ConnectivityLine.J.X;
                var y2 = beam.ConnectivityLine.J.Y;

                var v1 = new Point(x2, y2) - new Point(x1, y1);
                var v2 = new Vector(1, 0);

                var hwidth = textsize;
                var l = Geometrics.GetOffset(x1, y1, x2, y2, hwidth + 5/scale);

                var angle = Vector.AngleBetween(v1, v2);
                var x = 0.5 * (l.X1 + l.X2);
                var y = 0.5 * (l.Y1 + l.Y2);

                var r = new RotateTransform(angle, x, SelectableModel.FlipYAxis(y));
                dc.PushTransform(r);
                dc.DrawText(ft, SelectableModel.FlipYAxis(x, y));
            }
            _visuals.Add(drawingVisual);
        }
    }

    protected override Visual GetVisualChild(int index)
    {
        return _visuals[index];
    }

    protected override int VisualChildrenCount
    {
        get
        {
            return _visuals.Count;
        }
    }
}

我仍然得到模糊的结果。查看图像下部的中间光束文本

看看这篇文章-

由于WPF使用与设备无关的像素，因此在进行变换时，由于抗锯齿，它可以创建不规则的边缘渲染。像素捕捉是一种通过对视觉对象的几何体应用小偏移来抑制这些视觉伪影的方法，以将几何体与设备像素对齐

将UI元素的SnapsToDevicePixels属性设置为True应该可以解决您的问题。

感谢ramb00，我已经应用了所有这些方法，但结果是相同的。我已经读到WPF 4.0中修复了此问题，但我正在使用VS2012，问题仍然存在。您是否尝试过TextOptions。TextHintingMode=动画渲染。EdgeMode=别名？@HeenaPatil是，无改进：

TextOptions.SetTextFormattingMode(this, TextFormattingMode.Display);
