Ejemplos

En el ejemplo siguiente se muestra cómo un DynamicRenderer, que hereda de StylusPlugIn, usa un ImageBrush para representar un trazo. Este pincel dibuja parcialmente el archivo de imagen especificado por imageFile.

if (imageBrush == null)
{
    // Create an ImageBrush.  imageFile is a string that's a path to an image file.
    image1 = new BitmapImage(new Uri(imageFile));
    imageBrush = new ImageBrush(image1);

    // Don't tile, don't stretch; align to top/left.
    imageBrush.TileMode = TileMode.None;
    imageBrush.Stretch = Stretch.None;
    imageBrush.AlignmentX = AlignmentX.Left;
    imageBrush.AlignmentY = AlignmentY.Top;

    // Map the brush to the entire bounds of the element.
    imageBrush.ViewportUnits = BrushMappingMode.Absolute;
    imageBrush.Viewport = this.ElementBounds;
    imageBrush.Freeze();
}

If imageBrush Is Nothing Then
    ' Create an ImageBrush.  imageFile is a string that's a path to an image file.
    image1 = New BitmapImage(New Uri(imageFile))
    imageBrush = New ImageBrush(image1)
    
    ' Don't tile, don't stretch; align to top/left.
    imageBrush.TileMode = TileMode.None
    imageBrush.Stretch = Stretch.None
    imageBrush.AlignmentX = AlignmentX.Left
    imageBrush.AlignmentY = AlignmentY.Top
    
    ' Map the brush to the entire bounds of the element.
    imageBrush.ViewportUnits = BrushMappingMode.Absolute
    imageBrush.Viewport = ElementBounds
    imageBrush.Freeze()
End If
