SoftwareBitmap.CreateCopyFromSurfaceAsync 方法

定义

命名空间:

Windows.Graphics.Imaging

重载

CreateCopyFromSurfaceAsync(IDirect3DSurface)	通过执行提供的 IDirect3DSurface 的深层副本，异步创建新的 SoftwareBitmap。 对新 SoftwareBitmap 中的数据的修改不会影响创建它的图面。
CreateCopyFromSurfaceAsync(IDirect3DSurface, BitmapAlphaMode)	通过执行提供的 IDirect3DSurface 的深层副本，异步创建新的 SoftwareBitmap。 对新 SoftwareBitmap 中的数据的修改不会影响创建它的图面。

CreateCopyFromSurfaceAsync(IDirect3DSurface)

参数

surface

IDirect3DSurface

将从中创建副本的源图面。

返回
