GradientBrush.SpreadMethod Propriedade

Definição

Espaço de Nomes:
System.Windows.Media
Assemblagem:
PresentationCore.dll

Obtém ou define o tipo de método de espalhamento que especifica como desenhar um gradiente que começa ou termina dentro dos limites do objeto a ser pintado.

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

Valor de Propriedade

GradientSpreadMethod

O tipo de método de espalhamento usado para pintar o gradiente. A predefinição é Pad.

Observações

A ilustração seguinte mostra os métodos de dispersão disponíveis e o seu efeito em LinearGradientBrush e RadialGradientBrush. A linha vermelha indica o espaço de gradiente. A LinearGradientBrush define o seu espaço gradiente com as suas StartPoint propriedades e EndPoint . A RadialGradientBrush define o seu espaço de gradiente com as suas Center, RadiusX, e RadiusY propriedades.
