[Visual Basic] Public Function DecodeLatentImage(ByVal page As Long, ByVal light As Long, ByVal type_ As Long, ByVal decpar As String) As Long
[Delphi] function DecodeLatentImage(page: Integer; light: Integer; type_: Integer; decpar: WideString): Integer;
[C++] long DecodeLatentImage(long page, long light, long type_, BSTR decpar);
The returned image reference can be feed to a GxVariantOCX control, or it can
be passed to a GxImage control by its GetFromGxVariant method.
It is important that this value is not a simple integer but it represents a complex
internal data which is referenced internally each time it is accessed. So do use it
carefully (do not convert to / or compare with integers) to avoid memory leak problems.
