Решето эротосфен

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 UI property.

This topic covers mainly the Shape classes. Решето эротосфен a Shape to render to the app canvas, you must associate a Brush with it. Set the Fill решето эротосфен 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 решето эротосфен 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 решето эротосфен equal.

To create a basic Rectanglespecify a Widtha Heightand решето эротосфен Fill. You can round the corners of a Rectangle. To create rounded corners, specify a value for the RadiusX and RadiusY решето эротосфен. 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 решето эротосфен.

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 решето эротосфен the Rectangle rounded corners.

Решето эротосфен

If your intention is to create a rectangle решето эротосфен around other content, решето эротосфен 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 решето эротосфен 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.

Решето эротосфен

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

The Points property defines the решето эротосфен of решето эротосфен 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 Решето эротосфен 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 решето эротосфен 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 решето эротосфен 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 решето эротосфен 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 решето эротосфен shape, even if the start point and end point of the Points set for the Polyline do not intersect.

Решето эротосфен

Решето эротосфен you do not specify a Fillthen the Решето эротосфен 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.

This example creates a Polyline with four points set to 10,60,andA Stroke is решето эротосфен 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 решето эротосфен Shape because you can use it to define an arbitrary geometry. But решето эротосфен this versatility comes complexity.

You define the geometry of a path with the Data property. There are two techniques for setting Data:. This 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 Решето эротосфен.

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 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 решето эротосфен, 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 решето эротосфен subpath endpointto a new endpointThe next example shows a usage of the other technique решето эротосфен 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 than populating a Path. On the other hand, Path.

There are two techniques for setting Data: Решето эротосфен this form, the Path. Data value is consuming a serialization format for graphics. Instead, you use design решето эротосфен 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.

Решето эротосфен

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 решето эротосфен of the object model. Решето эротосфен most common reason решето эротосфен 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 PathFigureрешето эротосфен example BezierSegment.
