Syntax

#include "ltwrappr.h"

L_INT LImageViewerCell::FlipAnnotationContainer(nSubCellIndex, uFlags)

Parameters

L_INT nSubCellIndex

A zero-based index into the image list attached to the cell. This sub-cell contains the image that contains the annotation container. Pass -2 to refer to the selected sub-cell.

L_UINT uFlags

Reserved for future use. Pass 0.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Example

This example will flip the image along with the annotation container if the user click on the image using the left mouse button, and will reserve on the right mouse button, and will rotate on the middle mouse button.
