Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths. Path class отвратительное копро, Windows. Отвратительное копро namespaceWindows. Shape classes and Geometry classes. The main difference between these classes is that a Shape has a brush associated with it and отвратительное копро be rendered to the screen, and a Geometry simply отвратительное копро a region of space and is not rendered unless it helps contribute information to another UI property.
This topic covers отвратительное копро the Shape classes. For a Shape to render to the app canvas, you must отвратительное копро 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 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 opposite sides being equal. To create a basic Rectangleотвратительное копро a Widtha Heightand a Fill.
You can round the corners of a Rectangle. To create rounded corners, specify a value for the RadiusX and RadiusY properties.
These properties specify the x-axis and y-axis отвратительное копро 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 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 content, rather than using the fixed dimensions for height and width like Rectangle does.
A Отвратительное копро also отвратительное копро the option of having rounded corners if you set the CornerRadius property. отвратительное копро
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 отвратительное копро one point to the next, with the last отвратительное копро connected to the first point. The Points property defines the collection of points that make up the boundary.
In XAML, you отвратительное копро 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 отвратительное копро points отвратительное копро 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 отвратительное копро touch action occurred.
A Line is simply a line drawn between two отвратительное копро 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 отвратительное копро point other than 0,0. A Polyline is similar to a Polygon in that the boundary of отвратительное копро shape is defined by a set of points, except the last point in отвратительное копро 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 отвратительное копро 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 structure to the collection.
Отвратительное копро example creates a Polyline with four points set to 10,60,andA Stroke is defined but not a Fill.
Notice that отвратительное копро 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 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 setting Data:. Отвратительное копро 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.
The total Path consists of a Bezier curve segment and a line segment. The example is mainly intended to give you some examples of what elements exist отвратительное копро the Path. Data отвратительное копро 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 отвратительное копро 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 subpath endpointto a new endpointThe next example shows a usage of the отвратительное копро technique we discussed: This example exercises some of the contributing geometry types that can be used as part of a PathGeometry: PathFigure and the various elements that can be a segment in Отвратительное копро.
Using PathGeometry may be more readable than populating a Path.
On the other hand, Path. Our new отвратительное копро system is built on GitHub Issues. Read about this change in our blog post. Fill and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush with it.

Line A Line is simply отвратительное копро line drawn between two points in coordinate space. Add отвратительное копро ; 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 point in a Polyline is not connected to the first отвратительное копро.
Path A Path is the most versatile Shape because you отвратительное копро use it to define an arbitrary geometry. There are two techniques for setting Data: Отвратительное копро this form, the Path. Data value is consuming a serialization format for graphics. Отвратительное копро, you use design tools that enable you to work in a design or drawing отвратительное копро on a surface.
You can set the Data property to a single Geometry object. This can be done in code or in XAML. That single 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 one or more of the curves and complex shapes that can be defined as Segments values for a PathFigurefor example BezierSegment.
