Creates an OLE picture object that is directly mapped to a native TPicture.
procedure GetOlePicture(Picture: TPicture; var OlePicture: IPictureDisp);
GetOlePicture(TPicture Picture, IPictureDisp OlePicture);
AxCtrls
OLE conventions implement pictures as automation objects that contain the properties of the picture. This routine creates an adapter object that maps the properties of a native VCL TPicture into an OLE picture object, thereby allowing an OLE client to access the picture properties of a VCL control. Call this function when you implement a method that retrieves a TPicture value from a VCL object and returns it as an OLE picture.
The Picture parameter is a pointer to the native TPicture. This can be the Picture property of a VCL control. The OLE picture is returned in the OlePicture parameter. The resulting OLE picture object is a direct connection to the native VCL picture, so changing the OLE picture's properties will change the TPicture's properties, and vice-versa.
