This enables minimal markup for horizontal or vertical lines. Contributors In this article Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths.
You define the geometry of a path with the Data property. That single Geometry is typically a GeometryGroup , which acts as a container that can composite multiple geometry definitions into a single object for purposes of the object model.
Point , ; polyline1. Using PathGeometry may be more readable than populating a Path. Add pathGeometry1 ; path1.
The next example shows a usage of the other technique we discussed: This example shows a Path that might have resulted from using Blend for Visual Studio to produce just a few vector shapes and then saving the result as XAML.
This Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. This example exercises some of the contributing geometry types that can be used as part of a PathGeometry:
A Border also has the option of having rounded corners if you set the CornerRadius property. In code-behind, you use a PointCollection to define the points and you add each individual point as a Point structure to the collection. In XAML, you define the points with a comma-separated list.
If you specify a Fill of a Polyline , the Fill paints the interior space of the shape, even if the start point and end point of the Points set for the Polyline do not intersect. Instead, you use design tools that enable you to work in a design or drawing metaphor on a surface. There are two techniques for setting Data:
Fill and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush with it. The rendering logic for a Polygon assumes that you are defining a closed shape and will connect the end point to the start point implicitly. Add pathFigure1 ; pathGeometry1.
Notice that the first and last points are not connected by the Stroke outline as they are in a Polygon. In code-behind you use a PointCollection to define the points and you add each individual point as a Point value to the collection. If you do not specify a Fill, then the Polyline is similar to what would have rendered if you had specified several individual Line elements where the start points and end points of consecutive lines intersected.
You could then use a TranslateTransform to move the entire Line, if you wanted it to start at a point other than 0,0. Point , ; points. A Stroke also requires a Brush that defines its appearance, and should have a non-zero value for StrokeThickness.
You define the geometry of a path with the Data property. To create a basic Rectangle, specify a Width , a Height , and a Fill. The maximum allowed value of RadiusX is the Width divided by two and the maximum allowed value of RadiusY is the Height divided by two.
Rectangle A Rectangle is a four-sided shape with its opposite sides being equal. This example creates a Polyline with four points set to 10, , 60, , , , and ,
