Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths. Айзер импотент кончает classWindows. Shapes namespaceWindows. Shape classes and Geometry classes. The main difference between these classes is that a Shape has a 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 Айзер импотент кончает property.
This topic covers mainly the Shape classes.
For a Shape to render to the app canvas, you must 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 айзер импотент кончает perimeter. When an Ellipse is positioned in a UI layout, its size is assumed to be the same as a rectangle with that Width and Height ; the area outside the perimeter does not have rendering but still is part of its layout slot size.
A set of 6 Ellipse elements are 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 shape with its айзер импотент кончает sides being equal. To create a basic Rectanglespecify a Widtha Heightand a Fill. You can round the corners of a Rectangle. To create айзер импотент кончает corners, specify a айзер импотент кончает for the RadiusX and RadiusY properties. These properties specify the x-axis and y-axis of an ellipse that defines the curve of the corners.
Айзер импотент кончает 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 айзер импотент кончает example creates a Rectangle with a Width of and a Height of We set the StrokeThickness to 3. We 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 айзер импотент кончает, rather than using the fixed dimensions for height and width like Rectangle does.
A Border айзер импотент кончает 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 айзер импотент кончает 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 the 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 айзер импотент кончает 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 simply a line drawn between two points in coordinate space. A Line ignores any value provided for Fillbecause it has no interior space. This enables minimal markup for horizontal or 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 of points, except the last point in a Polyline is not connected to the first point.
If you specify a Fill of 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 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 айзер импотент кончает 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 not a Fill. Notice айзер импотент кончает the first and last points are not connected by the Stroke outline as they are in айзер импотент кончает Polygon.
A Path is the most versatile Shape because you can use айзер импотент кончает to define an arbitrary geometry. But with this versatility comes complexity. You define the geometry of a айзер импотент кончает with the Data property. There are two techniques for setting Data:.
This айзер импотент кончает 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.
The total Path consists of a Bezier curve segment and a line segment. The example is mainly intended to give you айзер импотент кончает examples 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 айзер импотент кончает 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 second segment begins with an absolute horizontal line command "H", which specifies a line drawn from the preceding айзер импотент кончает endpointto a new endpointThe next example shows a usage of the other technique we discussed: This example exercises some of the contributing geometry types that can be used as part айзер импотент кончает 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. Our new feedback system is built on GitHub Issues. Read about this change in our blog post. Fill and Stroke for shapes For айзер импотент кончает Shape to render to the app canvas, you must associate a Brush with it. Ellipse An Ellipse is айзер импотент кончает shape 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 айзер импотент кончает of points.

Data value is айзер импотент кончает 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 Geometry object. This can be done айзер импотент кончает code or in XAML. That single Geometry is typically a GeometryGroupwhich acts as a container that can composite multiple geometry definitions into a single айзер импотент кончает 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.
