LImageViewer::FlipAnnotationContainer

#include "ltwrappr.h"

L_INT LImageViewer::FlipAnnotationContainer(nCellIndex, nSubCellIndex, uFlags)

L_INT nCellIndex;	/* index of the cell */
L_INT nSubCellIndex;	/* index into the image list attached to the cell */
L_UINT uFlags;	/* reserved for future */

Flips the annotation container.

Parameter	Description
nCellIndex	A zero-based index of the cell to flip its annotation container. Pass -1 to flip the annotation container of all the cells in the container. Pass -2 to flip the annotation container of all the selected cells.
nSubCellIndex	A zero-based index into the image list attached to the cell specified in nCellIndex. This sub-cell contains the image that contains the annotation container. Pass -2 to refer to the selected sub-cell.
uFlags	Reserved for future use. Pass 0.

Returns

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

Comments

This function only flips the annotation container. It doesn't flip the image itself.

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 reservse on the right mouse button, and will rotate on the middle mouse button.
