Remarks

If the image data of this RasterImage object is stored in a global Windows handle, then use the Release method along with Access to control the access to image data in memory. Any attempt to access the image data after calling Release will result in an application error.

To make the most of available system resources, you should only keep a RasterImage object locked when you need to access the image data. Call Release to unlock the image data for more efficient use of system memory resources.

You should call this method whenever the image is not used, so that Windows can manage its memory properly.

If the image data of this RasterImage is not stored in a global Windows handle, then this method will do nothing and calling it will not have any affect on the RasterImage.

Use IsGlobalMemory to determine if the image data of this RasterImage is stored in a global Windows handle or not.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
