Shape отсос ослу 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 отсос ослу UI property. This topic covers mainly the Shape classes.
For a Отсос ослу 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 отсос ослу, 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 отсос ослу still is part отсос ослу 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 отсос ослу with its opposite sides being equal.
To create a basic Rectanglespecify a Widtha Heightand a Fill. You can round the corners of a Rectangle. To create rounded отсос ослу, specify a value for the RadiusX and RadiusY properties.
These properties specify the x-axis and y-axis of an ellipse отсос ослу defines the curve of the corners. The maximum allowed value отсос ослу RadiusX is the Width divided by two and the maximum allowed value of RadiusY is the Height divided by two.
Отсос ослу next example creates a Rectangle with a Width of and a Height of We set the Отсос ослу to 3. Отсос ослу set the RadiusX property to 50 and the RadiusY property to 10, отсос ослу 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 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 отсос ослу 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 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 отсос ослу 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 отсос ослу for Отсос ослуbecause 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 отсос ослу not connected to the first point.
If you specify a Fill of a Polylinethe Fill paints the interior отсос ослу 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 отсос ослу 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.
This example creates a Polyline with отсос ослу points set to 10,60,andA Stroke is defined but not a Fill. Notice that the first отсос ослу 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:. Отсос ослу 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 отсос ослу 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 at отсос ослу, and ends at отсос ослу,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 other 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 PathFigure.
Using PathGeometry may be more readable отсос ослу 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 a Shape to render to the отсос ослу canvas, you отсос ослу associate a Brush with it. Ellipse An Ellipse is a 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 number of points.

Path A Path is the most versatile Shape because you can use it to define an arbitrary geometry. There are two techniques for setting Data: In this form, the Path. Data value отсос ослу 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 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 отсос ослу for purposes of the отсос ослу model.
The most common reason for doing this is because you отсос ослу to use one or more of the curves and complex shapes that can be defined as Segments values for a PathFigurefor example BezierSegment.
