Learn how to draw shapes, such as ellipses, rectangles, polygons, and paths. Path classWindows. Shapes namespaceСисястыепорно. Shape classes and Geometry classes. The main difference between these classes is that a Shape has сисястыепорно brush associated with it and can be rendered to the screen, and a Сисястыепорно 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. For a Shape to render to the app canvas, you must associate a Brush with it. Set the Fill property сисястыепорно the Shape to the Brush you want. For more info about brushes, see Using brushes. Сисястыепорно Stroke also requires сисястыепорно 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 сисястыепорно size. A set сисястыепорно 6 Ellipse elements are part of the control template for the ProgressRing control, and 2 concentric Ellipse elements are part of сисястыепорно RadioButton. A Rectangle is a four-sided shape сисястыепорно its opposite sides being equal.
To create a basic Rectanglespecify a Widthсисястыепорно Heightand a Fill. You can round the corners of сисястыепорно Rectangle. To create rounded corners, specify a value сисястыепорно the RadiusX and RadiusY properties. 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 two. The next example creates a Rectangle with a Width of and a Height of We set the StrokeThickness сисястыепорно 3.
We set the RadiusX property to 50 and the RadiusY сисястыепорно to 10, which gives сисястыепорно Rectangle rounded corners. If your intention is to create a rectangle shape around other content, it сисястыепорно be better to use Border because it can have child content and will automatically size around that content, rather than сисястыепорно the fixed dimensions for сисястыепорно 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 сисястыепорно probably a better choice for control composition. Сисястыепорно Polygon is a shape 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 сисястыепорно PointCollection to define the points and you add each individual point as a Point value to the collection. Сисястыепорно rendering logic for a Polygon assumes that you are defining a сисястыепорно 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 Сисястыепорно is part of the сисястыепорно 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 сисястыепорно 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 Lineсисястыепорно you wanted it to сисястыепорно at a point other than 0,0. A Polyline сисястыепорно similar to a Polygon in that the boundary of the сисястыепорно is defined сисястыепорно 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 Polylineсисястыепорно Fill paints the interior space of the shape, сисястыепорно if the start point and сисястыепорно point of the Points set for the Polyline do not сисястыепорно. 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 сисястыепорно the collection of points that сисястыепорно up the boundary. In сисястыепорно, 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 defined but not сисястыепорно Fill. Notice that the сисястыепорно and last points are not connected by the Stroke outline as they сисястыепорно 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 сисястыепорно. 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 сисястыепорно resulted from using Blend for Visual Studio to produce just a few vector shapes and then сисястыепорно the result as XAML.
The сисястыепорно 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 сисястыепорно format and what the numbers represent. Сисястыепорно Data begins with the move command, indicated by "M", which establishes an absolute start point for the path. The first сисястыепорно is a cubic Bezier curve that begins atand ends at сисястыепорно,which is drawn by using the two control points ,25 andСисястыепорно segment is indicated by the "C" command in the Data attribute string.
The сисястыепорно segment begins with an absolute horizontal line command "H", which specifies a line сисястыепорно from the preceding subpath endpointсисястыепорно a new endpointThe next example shows a usage of the other сисястыепорно we discussed: This example exercises some of the contributing geometry types that can be used as part of a PathGeometry: PathFigure сисястыепорно the various elements that can be a segment in PathFigure.
Сисястыепорно PathGeometry may be more readable than populating a Path. On the other hand, Path. Our new feedback system is built on GitHub Issues. Read сисястыепорно this change in our сисястыепорно post. Fill and Stroke for shapes For a Shape to render to the app canvas, you must associate a Brush with it.
Ellipse An Ellipse is a shape with a сисястыепорно 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 a line drawn between two points in coordinate space.
Add line1 сисястыепорно 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 сисястыепорно the first point. Сисястыепорно; polyline1.
Path A Path is the сисястыепорно versatile Shape because you can use it to define an arbitrary geometry.
There сисястыепорно two techniques for setting Сисястыепорно In this form, the Path. Data value is 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 сисястыепорно code or in XAML. That single Geometry is typically a GeometryGroupwhich acts as a container that can composite multiple geometry definitions сисястыепорно a single object for purposes of the сисястыепорно 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. FromArgb,; path1. Add rectangleGeometry1 ; geometryGroup1.
Point 50, 50 ; pathFigureCollection1. Add pathFigure1 сисястыепорно pathGeometry1. Add pathSegment2 ; pathFigure1. Add сисястыепорно ; path1.
