	)

pure virtual

Disallow/allow participants to annotate when viewing the sharing content.

Parameters

[in]	viewtype	SDK_FIRST_VIEW/SDK_SECOND_VIEW
[in]	disable	TRUE means disabled, FALSE not.

Returns: If the user owns the authority, the return value is SDKErr_Success. Otherwise not. To get extended error information, see SDKError enum.

◆ GetCustomizedAnnotationController()

virtual ICustomizedAnnotationController* IAnnotationController::GetCustomizedAnnotationController ( ICustomizedShareRender * pShareRender = NULL )

pure virtual

Get the controller of annotation tools used in user custom interface mode.

Returns: If the function succeeds, the return value is the controller of annotation tools used in user custom interface mode. If the function fails, the return value is NULL.

Remarks: Valid only for user custom interface mode.

◆ IsAnnoataionDisable()

virtual bool IAnnotationController::IsAnnoataionDisable ( SDKViewType viewtype = SDK_FIRST_VIEW )

pure virtual

Determine if the annotation tools are disabled or not for the specified view during the current meeting.

Parameters

viewtype Specify which view to be determined. For more details, see SDKViewType enum.

Returns: FALSE indicates enabled while TRUE indicates disabled.

Remarks: Valid for both ZOOM style and user custom interface mode.

◆ IsViewerAnnotationDisabled()

virtual SDKError IAnnotationController::IsViewerAnnotationDisabled	(	SDKViewType	viewtype,
		bool &	bDisabled
	)

pure virtual

Determine if viewer's privilege of annotation is disabled.

Parameters

[in]	viewtype	SDK_FIRST_VIEW/SDK_SECOND_VIEW
[out]	bDisabled	TRUE means disabled, FALSE not. It validates only when the return value is SDKErr_Success.

Returns: If the user owns the authority, the return value is SDKErr_Success. Otherwise not. To get extended error information, see SDKError enum.

◆ Redo()

virtual SDKError IAnnotationController::Redo ( SDKViewType viewtype )

pure virtual

Redo the last-undo annotation.

Parameters

viewtype Specify on which view to redo the last-undo annotation. For more details, see SDKViewType enum.

Returns: If the function succeeds, the return value is SDKErr_Success. Otherwise failed. To get extended error information, see SDKError enum.

Remarks: Valid only for ZOOM style user interface mode.

◆ SetColor()
