Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths.

Path classWindows. Shapes namespaceWindows. Shape ирина литт and Geometry classes. The main difference between these classes is that a Shape has ирина литт brush associated with it and can be rendered to the screen, and a Geometry simply defines a region of space and is not rendered unless it helps contribute information to another UI property. This topic covers mainly the Shape classes. For a Shape to render to the app canvas, you ирина литт associate a Brush with it.

Set the Fill property of the Shape to the Brush you want. For more info about brushes, see Using brushes. A Stroke also requires a Brush that defines its appearance, and should have a non-zero value for StrokeThickness. An Ellipse is a shape with a curved perimeter.

When an Ellipse is positioned in a UI layout, its size is assumed to ирина литт the same as a rectangle with that Width and Height ; the area outside the perimeter does not have rendering but still is part of ирина литт layout slot size. A set of 6 Ellipse elements are part of the control template for the ProgressRing control, and 2 ирина литт Ellipse elements are part of a RadioButton.

A Rectangle is a four-sided shape with its opposite sides being ирина литт. To create a basic Rectanglespecify a Widtha Heightand a Fill. You can round the corners of a Rectangle. To create rounded corners, specify a value for the RadiusX and Ирина литт properties.

These properties specify the x-axis and y-axis of an ellipse that defines the curve of the corners. 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.

The next example creates a Rectangle with a Width of and a Height of We set ирина литт StrokeThickness to 3. Ирина литт set the RadiusX property to 50 and the RadiusY property to 10, which gives the Rectangle rounded corners. If your intention is to create a rectangle shape around other content, it might be better to use Border because it can have child content and will automatically size around that content, rather than using the fixed dimensions for height and width ирина литт Rectangle does.

A Border also has the option of having rounded corners if you set the CornerRadius property. On the other hand, a Rectangle is probably a better choice for control composition. A Polygon is a shape with a boundary defined by an arbitrary number of points. The boundary is created by connecting a line from one point to the next, with the last point connected to the first point.

The Points property defines ирина литт collection of points that make up the boundary. In XAML, you define the points with a comma-separated list. In code-behind you use a PointCollection to define the points and you add each individual point as a Point value to the collection. 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.

The next example creates a Polygon with 4 points set to 10,60,andFor example, a Point is part of the event data for touch events, so you can know exactly where in a coordinate space the touch action occurred.

A Line is ирина литт a line drawn between two points in coordinate space. A Line ignores any value provided for Fillbecause it has ирина литт interior space. This enables minimal markup for horizontal ирина литт vertical lines. You could then use a TranslateTransform to move the entire Lineif you wanted it to start at a point other than 0,0. A Polyline is similar to a Polygon in that the boundary of the shape is defined by a set ирина литт points, except ирина литт last point in a Polyline is not connected to the first point.

If you specify a Fill of a Ирина литтthe 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. If you do not specify a Fillthen 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.

As with a Polygonthe Points property defines the collection of points that make up the boundary.

In code-behind, you use a PointCollection to define the points and you add each individual point as a Point ирина литт to the collection. This example creates a Polyline with four points set to 10,60,ирина литт,andA Stroke is defined but not a Fill.

Notice that the first and last points are not connected by the Stroke outline as they are in a Polygon. A Path is the most versatile Shape because you can use it to define ирина литт arbitrary geometry.

But with this versatility comes complexity. You define the geometry of a path with the Data property. There are two techniques for setting Data:.

Ирина литт

This example shows a Path that might have resulted from using Blend for Visual Studio to ирина литт just a few vector shapes and then saving the ирина литт as XAML. The total Path consists of a Bezier curve segment and a line segment. The example is mainly intended to give you some ирина литт of what elements exist in the Path.

Data serialization format and what the numbers represent. This Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. The first segment is a cubic Bezier curve that begins atand ends at, which is drawn by using the two control points ,25 andThis segment is indicated by the "C" command in the Data attribute string. The ирина литт segment begins with an absolute horizontal line command "H", which specifies a line drawn from the preceding subpath endpointto a new endpointThe next example shows a usage of the other technique we discussed: This example exercises some of the contributing ирина литт types that can be used as part of a PathGeometry: PathFigure and the various elements that can be a segment in PathFigure.

Using PathGeometry may be more readable than populating a Path. On the other hand, Path.

Fill and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush ирина литт it. Ellipse An Ellipse is a shape with a ирина литт perimeter. Rectangle A Rectangle is a four-sided shape with its opposite sides being equal. Polygon A Polygon is a shape with a boundary defined by ирина литт arbitrary number of points. Point 10, ; points. Point 60, ; points.

Point; points. Point; polygon1. Line A Line is simply a line drawn between two points in coordinate space. Add line1 ; Polyline A Polyline is similar to a Polygon in that the boundary of the shape is defined by a set of points, except the last ирина литт in a Polyline is not connected to the first point. Point; polyline1. Path A Path is the most versatile Shape because you can use it to define ирина литт arbitrary geometry. There are two techniques for setting Data: In this form, the Path.

Data value is consuming a serialization format for graphics. Instead, you use design tools that enable you to work in a design or drawing metaphor on a surface.

You can set the Data property to a single Ирина литт object. This can be done in code or in XAML.

Ирина литт

That single Geometry is typically a GeometryGroupwhich acts as a container ирина литт can ирина литт multiple geometry definitions into a single object for purposes of the object model.

The most common reason for doing this is because you want to use one or more of the curves and complex shapes that can be defined as Segments values for a PathFigurefor example BezierSegment. FromArgb,; path1.
