<h1>Metafile </h1>
<p>The Metafile structure contains functions and structures to create and operate on
metafiles. A metafile is essentially a recording of drawing operations which can be stored
in a file, passed through the clipboard and replayed as needed. There are two types
of metafile: the old form represented by the HMETAFILE type and the new, enhanced
metafile, represented by the HENHMETAFILE type.</p>
<pre>structure Metafile :

type HENHMETAFILE

datatype MapMode = datatype Transform.MapMode
type METAFILEPICT = {mm: MapMode, size: SIZE, hMF: HMETAFILE}
type ENHMETAHEADER =
{
bounds: RECT, frame: RECT, fileSize: int, records: int,
handles: int, palEntries: int, resolutionPixels: SIZE,
resolutionMM: SIZE, openGL: bool
