SvgPathProperties

Features

• Parse SVG into class commands (Segments)
• Calculate the total length of a path (equivalent to getTotalLength)
• Get point at length (equivalent to getPointAtLength)
• Calculate bbox of a path (equivalent to getBBox)
• Fluent API to build a path
• Generate string path from the added commands

Usage

var properties = new SvgPath("M0,100 Q50,-50 100,100 T200,100");
var length = properties.GetTotalLength(); // double
var point = properties.GetPointAtLength(200); // Point
var tangent = properties.GetTangentAtLength(200); // Point
var allProperties = properties.GetPropertiesAtLength(200); // PointProperties
var parts = properties.GetParts(); // List<PartProperties>
var bbox = properties.GetBBox(); // Rect

new SvgPath("M 15 10 L 35 10")
    .AddVerticalLineTo(15)
    .AddHorizontalLineTo(40)
    .AddCubicBezierCurve(50, 5, 60, 15, 50, 25)
    .AddSmoothCubicBezierCurve(40, 20, 35, 30)
    .AddQuadraticBezierCurve(25, 40, 15, 30)
    .AddSmoothQuadraticBezierCurve(5, 15)
    .AddArc(1, 1, 0, false, false, 5, 5, unarc: true)
    .AddClosePath()
    .ToString();
