LinearGradientBrush.StartPoint Property

public:
 property System::Windows::Point StartPoint { System::Windows::Point get(); void set(System::Windows::Point value); };

public System.Windows.Point StartPoint { get; set; }

member this.StartPoint : System.Windows.Point with get, set

Public Property StartPoint As Point

Property Value

The starting two-dimensional coordinates for the linear gradient. The default is (0, 0).

Remarks

A LinearGradientBrush paints a gradient along a line. The line's start and end points are defined by the StartPoint and EndPoint properties of the LinearGradientBrush.

The default linear gradient is diagonal. In the default, the StartPoint of a linear gradient is (0,0), the upper-left corner of the area being filled, and its EndPoint is (1,1), the lower-right corner of the area being filled. The colors in the resulting gradient are interpolated along the diagonal path.

The following image shows a diagonal gradient. The black line was added to highlight the interpolation path of the gradient from the start point to the end point.

Specifying Relative or Absolute Values

Note that the MappingMode property of a LinearGradientBrush determines whether its StartPoint is interpreted as a relative or absolute value. A MappingMode of RelativeToBoundingBox specifies that the EndPoint value is relative to the size of the painted area. A MappingMode of Absolute specifies that the StartPoint value is expressed in device independent pixels. By default, the MappingMode is set to RelativeToBoundingBox, making the StartPoint a relative value.
