Acad::ErrorStatus setThumbnailBitmap( void* pBmp );
Description
This function will set the the thumbnail bitmap image for the database. The bitmap format is in Windows BITMAPINFO* format, but it needs to be passed as a void* pointer. If you have set a preview and want to clear it, you can call setThumbnailBitmap(NULL) to enforce saving with out any preview.
Note This function is intended for RealDWG developers. Preview thumbnail behavior reflects what the host application must do to generate a preview.
ObjectARX developers should not call this function because AutoCAD generates all preview thumbnails.
