GradientBrush.MappingMode GradientBrush.MappingMode GradientBrush.MappingMode GradientBrush.MappingMode Property

定義

グラデーション ブラシの配置座標が、出力領域に対し絶対的に配置されるか、または相対的に配置されるかを指定する BrushMappingMode 列挙を取得または設定します。Gets or sets a BrushMappingMode enumeration that specifies whether the gradient brush's positioning coordinates are absolute or relative to the output area.

public:
 property System::Windows::Media::BrushMappingMode MappingMode { System::Windows::Media::BrushMappingMode get(); void set(System::Windows::Media::BrushMappingMode value); };
public System.Windows.Media.BrushMappingMode MappingMode { get; set; }
member this.MappingMode : System.Windows.Media.BrushMappingMode with get, set
Public Property MappingMode As BrushMappingMode

プロパティ値

グラデーション ブラシの配置座標の解釈方法を指定する BrushMappingMode 値。A BrushMappingMode value that specifies how the gradient brush's positioning coordinates are interpreted. 既定値は、RelativeToBoundingBox です。The default is RelativeToBoundingBox.

次の例は、使用する方法を示します、MappingModeプロパティを使用するには、どのような座標システムを指定する、StartPointEndPointグラデーションの。The following example shows how to use the MappingMode property to specify what coordinate system to use for the StartPoint and EndPoint of the gradient.

        <!-- The MappingMode property is set to "Absolute" which specifies that the coordinate 
             system used for the StartPoint and EndPoint properties is not relative to the
