L_SetBitmapListItem

#include "l_bitmap.h"

L_LTKRN_API L_INT L_SetBitmapListItem(hList, uIndex, pBitmap)

HBITMAPLIST hList;	/* handle to the list of bitmaps */
L_UINT uIndex;	/* index of the bitmap to overwrite */
pBITMAPHANDLE pBitmap;	/* pointer to the source bitmap handle */

Overwrites the internal bitmap handle of a bitmap in a list. Use this function with L_GetBitmapListItem to manipulate a bitmap in a list.

Parameter	Description
hList	Handle to the list of bitmaps.
uIndex	Position of the bitmap in the list. Use zero-based indexing. For example, if there are 10 bitmaps in a list, the index of the last one is 9.
pBitmap	Pointer to the bitmap handle that will overwrite the internal bitmap handle in the list.

Returns

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

Comments

When a bitmap is in a list, you do not have direct access to the bitmap handle. Therefore, to do any image processing, you must first use L_GetBitmapListItem to get a copy of the internal handle, then do the image processing, then update the internal handle using L_SetBitmapListItem.

You cannot use this function to update a bitmap list while it is being used in an animation playback.
