Windows 8 Store Apps學習(14) 控件UI

編輯：關於.NET

控件 UI RenderTransform, Projection, Clip, UseLa

介紹

重新想象 Windows 8 Store Apps 之控件 UI

RenderTransform - 變換（用於做位移，旋轉，縮放，扭曲等變換）

Projection - 映射

Clip - 剪裁並顯示 UIElement 的指定區域

UseLayoutRounding - 是否使用完整像素布局

示例

1、演示 RenderTransform 的應用

                UseLayoutRounding - 是否使用完整像素布局。默認值為 true
                    舉例：
、如果設置了Margin="1.6"（非完整像素）
、那麼UseLayoutRounding="true"時，則容器的外邊距不相等；UseLayoutRounding="false"時，則容器的外

邊距相等
