HWND hCellWnd;	/* handle to the cell window */
LPTSTR pFileName;	/* output file name */
L_INT nSubCellIndex;	/* index into the image list attached to the cell */
L_INT nStartPage;	/* the page number of a multi-page file */
L_UINT uFlags;	/* flag */

Saves the annotation of the specified cell or sub-cell to a file.

Parameter	Description
hCellWnd	A handle to the window that represents the cell on which the function's effect will be applied.

nSubCellIndex	A zero-based index into the image list attached to the cell specified in nCellIndex. This sub-cell contains the image the annotation that will be saved. Pass -2 to refer to the selected sub-cell. If the cell contains 1 frame then the nSubCellIndex should be 0.
nStartPage	The page number of a multi-page file, which can contain more than one image.
uFlags	Flag that is used to determine the way of saving the annotation. Possible values are:
	Value	Meaning
