+ * You can #define JPEG_USE_FILE_IO_CUSTOM in jconfig.h to use custom file
+ * I/O functions implemented in Delphi VCL (Visual Component Library)
+ * in Vcl.Imaging.jpeg.pas for the TJPEGImage component utilizing
+ * the Delphi RTL (Run-Time Library) TMemoryStream component:
+ *
+ *   procedure jpeg_stdio_src(var cinfo: jpeg_decompress_struct;
+ *     input_file: TStream); external;
+ *
+ *   procedure jpeg_stdio_dest(var cinfo: jpeg_compress_struct;
+ *     output_file: TStream); external;
+ *
+ *   function jfread(var buf; recsize, reccount: Integer; S: TStream): Integer;
+ *   begin
+ *     Result := S.Read(buf, recsize * reccount);
+ *   end;
+ *
+ *   function jfwrite(const buf; recsize, reccount: Integer; S: TStream): Integer;
+ *   begin
+ *     Result := S.Write(buf, recsize * reccount);
+ *   end;
+ *
+ *   function jfflush(S: TStream): Integer;
+ *   begin
+ *     Result := 0;
+ *   end;
+ *
+ *   function jferror(S: TStream): Integer;
+ *   begin
+ *     Result := 0;
+ *   end;
+ *
+ * TMemoryStream of Delphi RTL has the distinctive feature to provide dynamic
+ * memory buffer management with a file/stream-based interface, particularly for
+ * the write (output) operation, which is easier to apply compared with direct
+ * implementations as given in jdatadst.c for memory destination.  Those direct
+ * implementations of dynamic memory write tend to be more difficult to use,
+ * so providing an option like TMemoryStream may be a useful alternative.
+ *
+ * The CFile/CMemFile classes of the Microsoft Foundation Class (MFC) Library
+ * may be used in a similar fashion.
