]Image class
A base class for System::Drawing::Bitmap and System::Drawing::Metafile classes providing basic functionality. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class Image : public virtual System::IDisposable
