An enhanced-format metafile is used by Win32-based applications. The enhanced format consists of the following elements:
Enhanced metafiles provide true device independence. You can think of the picture stored in an enhanced metafile as a "snapshot" of the video display taken at a particular moment. This "snapshot" maintains its dimensions no matter where it appears: on a printer, a plotter, or the desktop, or in the client area of any Win32-based application.
You can use enhanced metafiles to store a picture created by using the Win32 GDI functions (including new path and transformation functions). Because the enhanced metafile format is standardized, pictures that are stored in this format can be copied from one Win32-based application to another; and, because the pictures are truly device independent, they are guaranteed to maintain their shape and proportion on any output device.
