Capturing screen to in-memory bitmap is extremely easy. All you need is to create a bitmap instance with appropriate size
截圖到一個內存裏面的位圖非常的監督，你只需要創建一個適當大小的位圖實例。

CWsScreenDevice* screenDev = CCoeEnv::Static()->ScreenDevice();

CFbsBitmap* bitmap = new (ELeave) CFbsBitmap;

CleanupStack::PushL( bitmap );

User::LeaveIfError( bitmap->Create( screenDev->SizeInPixels(),
	screenDev->DisplayMode() ) );

and then copy screen content into it as follows
然後像下面這樣，將屏幕內容拷貝到它裏面。

User::LeaveIfError( screenDev->CopyScreenToBitmap( bitmap ) );
// use bitmap as appropriate, for example save it to file

CleanupStack::PopAndDestroy( bitmap );

This code links against fbscli.lib and ws32.lib
這些代碼需要鏈接fbscli.lib 和ws32.lib 兩個庫。
