.wmf metafile format
a metafile for the microsoft windows operating system consists of a collection of graphics device interface (gdi) functions that describe an image. because metafiles take up less space and are more device-independent than bitmaps, they provide convenient storage for images that appear repeatedly in an application or need to be moved from one application to another. to generate a metafile, a windows application creates a special device context that sends gdi commands to a file or memory for storage. the application can later play back the metafile and display the image. during playback, windows breaks the metafile down into records and identifies each object with an index to a handle table. when a meta_deleteobject record is encountered during playback, the associated object is deleted from the handle table. the entry is then reused by the next object that the metafile creates. to ensure compatibility, an application that explicitly manipulates records or builds its own metafile should manage the handle table in the same way. for more information on the format of the handle table, see the handletable structure. a met
