Public Property IsPixelSnappingEnabled As Boolean

属性值

true 如果合成引擎将呈现的视觉对象与像素边界对齐，则为 ;否则为 false。 默认值为 false。

示例

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;
}

注解

像素对齐允许你请求合成引擎在呈现时稍微调整可视化树的位置，使其原点与像素边界完美对齐。 这牺牲了位置准确性，以换取纹理的采样工件减少。
