L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerFlipAnnotationContainer(hCon, nCellIndex, nSubCellIndex, uFlags)

HDISPCONTAINER hCon;

/* handle to the container */

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

hCon

Handle to the container.

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.
