We call these displayables image-like because they take up a rectangular area of the screen, and do not react to input. These differ from normal images by varying their size to fill an area (Frame, LiveTile, and Solid), or by allowing the user to specify their size (LiveComposite, LiveCrop, Null). They are not image manipulators.

我们把这类displayable成为类图像的是因为他们在屏幕上占据了一个矩形的区域，并且不会对输入做出响应。和普通的图像不同之处在于这种displayable会改变自身大小来填充一个区域(Frame、LiveTile或Solid)，或者允许用户来指定他们的大小 (LiveComposite、LiveCrop、Null)。他们不能操作图像。

This flattens `child`, which may be made up of multiple textures, into a single texture.

Certain operations, like the alpha transform property, apply to every texture making up a displayable, which can yield incorrect results when the textures overlap on screen. Flatten creates a single texture from multiple textures, which can prevent this problem.
|
|
|
|
|
比如Alpha变换处理这样的操作应用于构成displayable的所有纹理，可能会在纹理重叠于屏幕上时发生错误。此操作会将多个纹理转换成单个纹理，避免错误。

Flatten is a relatively expensive operation, and so should only be used when absolutely required.
|
|
|
|
|
平铺是一个相对消耗资源的操作，仅在有必要时使用。
