# PathGeometry
|
|
|
|
In order to create a specific RadPath, you need to set a **RadPathGeometry** object to its **Geometry** property. The **RadPathGeometry** object exposes a **Figures** property which is a collection of **RadPathFigures**.
|
|
|
|
## RadPathFigure
|
|
|
|
Each of the RadPathFigure objects is composed of one or several segments. These can be a **RadArcSegment** or a **RadLineSegment**. Adding several segments in combination with setting up the **StartPoint** of the RadPathFigure is enough for you to create the desired figure which should be added to the figures collection of the geometry.
|
|
|
|
Each line or arc segment you add to the path figure is drawn consequently - its starting point is the last point of the previous segment of the Segments collection of the PathFigure object. The first segment uses the **StartPoint** of the path figure as starting point.
|
|
|
|
### RadArcSegment
|
|
|
|
The **RadArcSegment** represents an elliptical arc between two points. It exposes the following properties:
|
|
|
|
* **Center**: Defines the center point of the arc.
|
|
* **Size:** Sets the x- and y-diameter of the arc as a Size structure.
|
|
* **StartAngle**: Determines the angle from which the arc segment will start.
|
|
* **SweepAngle**: Specifies the length in degrees from the first to the second arc point. Positive angles are counter clockwise and negative angles clockwise.
|
|
|
|
The scheme below shows how **StartAngle** and **SweepAngle** are applied to the ArcSegment:
|
|
|
|
|
|
|
|
Here is a sample implementation of an **RadArcSegment** object:
|
|
|
|
<snippet id='path-geometry-simplearc-xaml' />
|
|
|
|
### RadLineSegment
|
|
|
|
Creates a line between two points in a **RadPathFigure**. The starting point of the line is defined either by the previous segment's end point or by the **StartPoint** of the PathFigure object. The end point is defined by the **Point** property of the LineSegment object.
|
|
|
|
The thickness and the color of the line are determined by the **StrokeThickness** and **Stroke** properties of the Path object this line figure is added to.
|
|
|
|
Check below a simple example of how to create a line PathFigure:
|
|
|
|
<snippet id='path-geometry-simpleline-xaml'/>
|
|
|
|
## Example
|
|
|
|
The following example shows how to create a more complex **RadPathGeometry** object and add a line with curved edges to its Figures collection.
|
|
|
|
First you should define the **RadPath** figure:
|
|
|
|
<snippet id='path-geometry-customline-xaml'/>
|
|
|
|
And then you set its **Geometry** to have the following structure:
|
|
|
|
<snippet id='path-geometry-customline-segment'/>
|
|
|
|
Check the screenshot below which shows the result after creating the three Paths:
