Public Property IsPixelSnappingEnabled As Boolean

屬性值

true如果合成引擎將渲染的視覺元素與像素邊界對齊;否則，。 false 預設值為 false。

範例

public Visual CreateVisualTree(Compositor compositor)
{
    // Say we have two visuals, one containing an image and one containing text.
    // The image can be resampled and still look fine, but the text looks bad if
    // it doesn't land perfectly on pixel boundaries.
    var root = compositor.CreateContainerVisual();

    var imageVisual = compositor.CreateSpriteVisual();
    ImageLoadingHelper(imageVisual);

    var textVisual = compositor.CreateSpriteVisual();
    TextLoadingHelper(textVisual);

    textVisual.Offset = new Vector3(50, 0, 0);
    textVisual.IsPixelSnappingEnabled = true;

    root.Children.Add(imageVisual);
    root.Children.Add(textVisual);

    return root;
}

備註

像素吸附讓你在渲染時請求合成引擎稍微調整視覺樹的位置，使其原點與像素邊界完美對齊。 這犧牲了位置精度，換取紋理取樣失真減少。
