MultiplyTransform(Matrix, MatrixOrder)

Origem:

LinearGradientBrush.cs

Multiplica o Matrix que representa a transformação geométrica local dessa LinearGradientBrush pelo Matrix especificado na ordem especificada.

public:
 void MultiplyTransform(System::Drawing::Drawing2D::Matrix ^ matrix, System::Drawing::Drawing2D::MatrixOrder order);

public void MultiplyTransform (System.Drawing.Drawing2D.Matrix matrix, System.Drawing.Drawing2D.MatrixOrder order);

member this.MultiplyTransform : System.Drawing.Drawing2D.Matrix * System.Drawing.Drawing2D.MatrixOrder -> unit

Public Sub MultiplyTransform (matrix As Matrix, order As MatrixOrder)

Parâmetros

matrix

Matrix

O Matrix pelo qual multiplicar a transformação geométrica.

order

MatrixOrder

Um MatrixOrder que especifica em qual ordem multiplicar as duas matrizes.

Exemplos

O exemplo de código a seguir foi projetado para uso com o Windows Forms e requer PaintEventArgse, um objeto de evento OnPaint. O código executa as seguintes ações:

• Cria um novo LinearGradientBrush.

• Desenha uma elipse na tela usando esse pincel.

• Chama o método MultiplyTransform para transformar o LinearGradientBrush.

• Desenha uma elipse para a tela diretamente abaixo da primeira elipse, usando o pincel transformado.

Observe que a elipse inferior é estendida na direção horizontal e que o gradiente é estendido para corresponder à nova forma.
