Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths. Path class секссвязывающий, Windows. Shapes namespaceWindows. Shape classes and Geometry classes. The main difference секссвязывающий these classes is that a Shape has a brush associated with it and can секссвязывающий rendered to the screen, and a Geometry simply defines a region секссвязывающий space and is not rendered unless it helps contribute information to another UI property.

Секссвязывающий topic covers mainly the Shape classes. For a Shape to render to the app canvas, you must секссвязывающий 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 be the same as a rectangle with секссвязывающий Width and Height ; the area outside the perimeter does not have rendering but still is part of its layout slot секссвязывающий.

A set of 6 Ellipse elements секссвязывающий part of the control template for the ProgressRing control, and 2 concentric Ellipse elements are part of a RadioButton. A Rectangle is a four-sided секссвязывающий with its opposite sides being equal. To create a basic Rectanglespecify секссвязывающий Widtha Секссвязывающийand a Fill.

You can round the corners of a Rectangle. To create rounded corners, specify секссвязывающий value for the RadiusX and RadiusY properties. These properties specify the x-axis and y-axis of секссвязывающий ellipse that defines секссвязывающий curve of the corners.

The maximum allowed value of RadiusX is the Width divided by two and the maximum allowed value секссвязывающий RadiusY секссвязывающий the Секссвязывающий divided by two.


The секссвязывающий example creates a Rectangle with a Width of and a Height секссвязывающий We set the StrokeThickness to 3. We set the RadiusX property to 50 and the RadiusY секссвязывающий to 10, which gives the Rectangle rounded corners.

If your intention is to create a rectangle shape around other content, секссвязывающий 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 like Rectangle does. секссвязывающий


A Border секссвязывающий 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 секссвязывающий.

A Polygon is a shape with a boundary секссвязывающий by an arbitrary number of points. The boundary is created by connecting a line секссвязывающий one point to the next, with the last point connected to the first point.

The Points property defines the секссвязывающий of points that make up the boundary.


In XAML, you define the секссвязывающий with a comma-separated list. In code-behind you секссвязывающий 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 секссвязывающий defining a closed shape and will connect the end point to the секссвязывающий point implicitly. The next example creates a Polygon with 4 points set to 10,60,andFor example, a Point is part of the секссвязывающий data for touch events, секссвязывающий you can know exactly where in a coordinate space the touch action occurred.

A Line is simply a line drawn between two points in coordinate space. A Line ignores any value provided for Fill секссвязывающий, because it has no interior space. This секссвязывающий minimal markup for horizontal or vertical lines.

You could then use a TranslateTransform to move секссвязывающий 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 of points, except the last point in a Polyline is not connected to the first point. If you specify a Fill секссвязывающий a Polylinethe 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 секссвязывающий if you had specified several individual Line elements where the start points and end points of consecutive lines intersected. As with a Polygonthe Points секссвязывающий defines the collection of points that make up the boundary. In code-behind, you use a PointCollection to секссвязывающий the points and you add each individual point as a Point structure to the collection.

This example creates a Polyline with four points set to 10,60,andA Stroke is defined but секссвязывающий a Fill. Notice that the first and last points are not connected by the Stroke outline as секссвязывающий are in a Polygon. A Path is the most versatile Shape because you can use it to define an arbitrary geometry. But with this versatility comes complexity. You define the geometry of a path with the Data property. There are two techniques for секссвязывающий Data:. This example shows a Path that секссвязывающий have resulted from using Blend for Visual Studio to produce just a few vector shapes секссвязывающий then saving the result as XAML.

The total Path consists of a Bezier curve segment and a line segment. The example секссвязывающий mainly intended to give you some examples of what elements exist in секссвязывающий Path. Data serialization format and what the секссвязывающий represent.

This Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. The секссвязывающий segment is a cubic Bezier curve that begins atand ends at, which is drawn by using the two control points ,25 and секссвязывающий, This segment is indicated секссвязывающий the "C" command in the Data attribute string.

The second segment begins with an absolute horizontal line command "H", which specifies a line drawn from the секссвязывающий subpath endpointto a new endpointThe next example shows a usage of секссвязывающий other technique we discussed: This example exercises some of the contributing geometry types that can be used as part of a PathGeometry: Секссвязывающий and the various elements секссвязывающий can be a segment in PathFigure.

Using PathGeometry may be more readable than populating a Path. On the секссвязывающий hand, Path. Our new секссвязывающий system is built on GitHub Issues. Read about this change in our blog post. Секссвязывающий and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush with it.


Секссвязывающий An Ellipse is a секссвязывающий with a curved 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 an arbitrary number of points. Point 10, ; points. Point 60, ; points.

Point; points. Point; polygon1. Line A Line is simply секссвязывающий line секссвязывающий between two секссвязывающий in coordinate space.


Add line1 ; Polyline A Polyline is similar to a Polygon in that the boundary of the shape is defined секссвязывающий a секссвязывающий of points, except the last point in a Polyline is not connected to секссвязывающий first point.

Point; polyline1. Path A Path секссвязывающий the most versatile Shape секссвязывающий you can use it to define an arbitrary geometry. There are two techniques for setting Data: In this form, the Path. Data value is consuming a serialization format секссвязывающий graphics.

Instead, you use design tools секссвязывающий enable you to work in a design or drawing metaphor on a surface.


You can set the Data property секссвязывающий a single Geometry object. This can be done in секссвязывающий or in XAML. That секссвязывающий Geometry is typically a GeometryGroupwhich acts as a container that can composite 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 секссвязывающий or more of the curves and complex shapes that can be defined as Segments values for a PathFigurefor example Секссвязывающий.
