若要创建立方贝塞尔曲线,请使用 PathGeometry、PathFigure和BezierSegment 类。 若要显示生成的几何图形,请使用 Path 元素,或者将其与 GeometryDrawing 或DrawingContext一起使用。 在以下示例中,从(10, 100) 到(300, 100) 绘制一条立方贝塞尔曲线。 曲线的控制点为(100,0)和(200,200)。
In XAML, you may also draw a quadratic Bezier curve using object element syntax. The following is equivalent to the previous XAML example. XAML 複製 <Path Stroke="Black" StrokeThickness="1"> <Path.Data> <PathGeometry> <PathGeometry.Figures> <PathFigureCollection> <PathFigure StartPoint="10,...
We can use the paths to draw curves and complex shapes on theICanvasusing theDrawPathmethod, which requires aPathFargument. A contour generally begins with a call to thePathF.MoveTomethod, which establishes a point at the beginning of the contour and an initial current point. You can then ...
This example shows how to draw an elliptical arc. To create an elliptical arc, use the PathGeometry, PathFigure, and ArcSegment classes.ExampleIn the following examples, an elliptical arc is drawn from (10,100) to (200,100). The arc has a Size of 100 by 50 device-independent pixels, ...
In this case, the arguments are coordinates; both commands require a single X/Y pair. In other words, we can read the above path as: "Move to {x: 100, y: 100}, then draw a line to {x: 200, y: 100}", and so on. The coordinate system is relative to the values specified in...
AnSKPathis created. We begin by moving to the starting point withMoveTo. Then we create two cubic lines withQuadTo. canvas.DrawPath(path, p1); The generated path is drawn to the canvas withDrawPath. Source SkiaSharp Github page In this article we have created 2D graphics in C# using Skia...
In most of applications either quadratic or cubic bezier function is used. However, you can always make use of higher degree bezier function to draw more complicated curves but calculation of higher degree bezier function is more complex and increases processing overhead. So, instead of using high...
To draw a cubic Bézier curve, one supplies these two control points first and then the destination as the third coordinate. Like all of the other SVG paths, it begins wherever the previous command left off. varpaper=Raphael(0,0,500,500);// draw the control points for educational purposes...
