#include "l_bitmap.h"

L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerGetRotateBitmapPerspectiveAngle(hCellWnd, nSubCellIndex, pnAngle, uFlags)

HWND hCellWnd;	/* handle to the cell window */
L_INT nSubCellIndex;	/* index into the image list attached to the cell */
L_INT * pnAngle;	/* pointer to a variable to be updated */
L_UINT uFlags;	/* reserved for future use */

Gets the perspective rotation angle of the specified cell or sub-cell.

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. The perspective rotation angle of this image will be retrieved. Pass -2 to retrieve the perspective rotation angle of the image in the selected sub-cell.
pnAngle	Address of the variable to be updated with the perspective rotation angle value.
uFlags	Reserved for future use. Pass 0.

Returns

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

Comments

To set the rotation angle of a specific cell or sub-cell, it is highly recommended to use L_DispContainerRotateBitmapPerspective instead of the standard L_RotateBitmapViewPerspective.
