GradientBrush.MappingMode プロパティ

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

BrushMappingMode

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.

次の例では、プロパティを使用し MappingMode て、グラデーションのおよびに使用する座標系を指定する方法を示し StartPoint EndPoint ます。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

             100 percent of the output area.  -->

注釈

値がの場合、 Absolute グラデーションブラシの座標はデバイス非依存のピクセルを使用して表されます。A value of Absolute indicates the gradient brush's coordinates are expressed using device independent pixels.
