C#) How to get bitmap IntPtr from RasterImage?

[Anonymous]

Hi.

I tried to get Bitmap IntPtr by RasterImage but I failed.

RasterImageDef imageDef = trans.GetObject(myImage.ImageDefId, OpenMode.ForWrite) as RasterImageDef;

imageDef.ImageCopy(true);

imageDef.OpenImage(); 

imageDef.ImageCopy(true); Method result => IntPtr = 0

imageDef.OpenImage();  Method result => Error

How to get Intptr?

Thanks.
