示例
下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse
,这是 Paint 事件处理程序的参数。 该代码执行以下操作:
创建
transformMatrix
矩阵(两个乘以两个标识矩阵加上零转换向量)。按向量转换转换矩阵(200,100)。
将 Windows 窗体的世界转换矩阵旋转 30 度,将旋转矩阵追加到窗体的转换矩阵前 30 度。
将旋转的世界转换矩阵乘以转换
transformMatrix
,并将transformMatrix
追加到世界转换矩阵。绘制旋转的翻译椭圆。
public:
void MultiplyTransformMatrixOrder( PaintEventArgs^ e )
{
// Create transform matrix.
Matrix^ transformMatrix = gcnew Matrix;
// Translate matrix, prepending translation vector.
transformMatrix->Translate( 200.0F, 100.0F );
// Rotate transformation matrix of graphics object,
// prepending rotation matrix.
e->Graphics->RotateTransform( 30.0F );
// Multiply (append to) transformation matrix of
// graphics object to translate graphics transformation.
e->Graphics->MultiplyTransform( transformMatrix, MatrixOrder::Append );
// Draw rotated, translated ellipse.
e->Graphics->DrawEllipse( gcnew Pen( Color::Blue,3.0f ), -80, -40, 160, 80 );
}
private void MultiplyTransformMatrixOrder(PaintEventArgs e)
{
// Create transform matrix.
Matrix transformMatrix = new Matrix();
// Translate matrix, prepending translation vector.
transformMatrix.Translate(200.0F, 100.0F);
// Rotate transformation matrix of graphics object,
// prepending rotation matrix.
e.Graphics.RotateTransform(30.0F);
// Multiply (append to) transformation matrix of
// graphics object to translate graphics transformation.
e.Graphics.MultiplyTransform(transformMatrix, MatrixOrder.Append);
// Draw rotated, translated ellipse.
e.Graphics.DrawEllipse(new Pen(Color.Blue, 3), -80, -40, 160, 80);
}
Private Sub MultiplyTransformMatrixOrder(ByVal e As PaintEventArgs)
' Create transform matrix.
Dim transformMatrix As New Matrix
' Translate matrix, prepending translation vector.
transformMatrix.Translate(200.0F, 100.0F)
' Rotate transformation matrix of graphics object,
' prepending rotation matrix.
e.Graphics.RotateTransform(30.0F)
' Multiply (append to) transformation matrix of
' graphics object to translate graphics transformation.
e.Graphics.MultiplyTransform(transformMatrix, MatrixOrder.Append)
' Draw rotated, translated ellipse.
e.Graphics.DrawEllipse(New Pen(Color.Blue, 3), -80, -40, 160, 80)
End Sub
