Syntax

short GetOverlayBitmapList(long lOverlayIndex, long lFrameIndex, long lCount, long lFlags);

Overview

Refer to Overlays Overview.

Remarks

The GetOverlayBitmapList method loads a bitmap list with frames from the "Overlay Data" (60xx, 3000) element of the specified overlay. The handle to the bitmap list can then be obtained by accessing the OverlayBitmapList property.

Before calling this method, you need to use the GetOverlayAttributes method to get the number of frames under the overlay. The NumberFramesInOverlay property specifies this number.

As an example, if you wish to load 5 frames starting with the 1st frame in the "Overlay Data", call this method with lFrameIndex set to 0 and lCount set to 5.
