GetOverlayBitmap method (ILEADRasterProcess)

Visual Basic example

Visual C++ 6.0 example

 

Syntax

short GetOverlayBitmap(ILEADRaster *pRaster, short iIndex, ILEADRaster *pOverlayRaster, long lFlags);

Overview

Refer to Overlays Overview.

Remarks

(Medical only) Gets the overlay bitmap for the specified index.

This method can be used to get a copy of the overlay bitmap (OVERLAY_COPY) or to get the bitmap without making a copy (OVERLAY_NOCOPY or OVERLAY_MOVE).

The quickest way to get the overlay bitmap is to avoid making a copy.

If OVERLAY_MOVE is set in lFlags, the overlay bitmap from the corresponding index will be invalidated.

pOverlayRaster is assumed to be unallocated and uninitialized. It will be filled without freeing the existing data.
