将SVG路径数据转换为GDI + GraphicsPath数据
||
有没有一种简单的方法可以将SVG路径标签转换为C＃System.Drawing.Drawing2D.GraphicsPath？它们都息息相关，我希望可以轻松地将SVG路径数据转换为GraphicsPath Points。

var pathData = ...; var graphicsPath = new GraphicsPath(); foreach (var segment in SvgPathBuilder.Parse(pathData)) segment.AddToPath(graphicsPath); graphics.DrawPath(Pens.Black, graphicsPath);赣借
看起来相似并且具有相同的目的，但是在事物的指定和处理方式上还是存在一些差异。一个示例：SVG弧定义与定义弧的方式不同，因此您需要做一点三角函数以将其转换。 还检查.NET / C＃中的Drawing SVG吗？箩冀娥

函数，则您的方法如下所示：private GraphicsPath svgMLQZToGraphicsPath(string svgString) { GraphicsPath graphicsPath = new GraphicsPath(); float[] x = new float[4]; float[] y = new float[4]; string prev = \"\"; string[] splits = svgString.Split(\' \'); for (int s = 0; s < splits.Length; s++) { if (splits[s].Substring(0, 1) == \"M\") { x[0] = float.Parse(splits[s].Substring(1).Replace(\'.\', \',\')); y[0] = float.Parse(splits[s + 1].Replace(\'.\', \',\')); s++; prev = \"M\"; graphicsPath.StartFigure(); } else if (splits[s].Substring(0, 1) == \"L\") { x[1] = float.Parse(splits[s].Substring(1).Replace(\'.\', \',\')); y[1] = float.Parse(splits[s + 1].Replace(\'.\', \',\')); graphicsPath.AddLine(new PointF(x[0], y[0]), new PointF(x[1], y[1])); x[0] = x[1]; // x[1] = new float(); y[0] = y[1]; //y[1] = new float(); s++; prev = \"L\"; } else if (splits[s].Substring(0, 1) == \"Q\") { x[1] = x[0] + (2 / 3) * (float.Parse(splits[s].Substring(1).Replace(\'.\', \',\')) - x[0]); y[1] = y[0] + (2 / 3) * (float.Parse(splits[s + 1].Replace(\'.\', \',\')) - y[0]); x[3] = float.Parse(splits[s + 2].Replace(\'.\', \',\')); y[3] = float.Parse(splits[s + 3].Replace(\'.\', \',\')); x[2] = x[3] + (2 / 3) * (float.Parse(splits[s].Substring(1).Replace(\'.\', \',\')) - y[3]); y[2] = y[3] + (2 / 3) * (float.Parse(splits[s + 1].Replace(\'.\', \',\')) - y[3]); graphicsPath.AddBezier(new PointF(x[0], y[0]), new PointF(x[1], y[1]), new PointF(x[2], y[2]), new PointF(x[3], y[3])); x[0] = x[3]; y[0] = y[3]; s = s + 3; prev = \"Q\"; } else if (splits[s].Substring(0, 1) == \"Z\") { graphicsPath.CloseFigure(); if (splits[s].Length >= 2 && splits[s].Substring(0, 2) == \"ZM\") { x[0] = float.Parse(splits[s].Substring(2).Replace(\'.\', \',\')); y[0] = float.Parse(splits[s + 1].Replace(\'.\', \',\')); s++; graphicsPath.StartFigure(); prev = \"M\"; } } else { string ok = @\"^[a-zA-Z]*$\"; if (!Regex.IsMatch(splits[s + 1].Substring(0, 1), ok)) { string replace = prev + splits[s + 1]; splits[s + 1] = replace; } } } return graphicsPath; }
