	GFF Format Summary: Microsoft Windows Metafile (Site not responding. Last check: 2007-10-05)
		If the metafile data grows too large to be stored in memory, or needs to be saved before an application terminates, the data can be written to disk in the form of a WMF or EMF file and played back from disk.
		Clipboard metafiles are also based on the standard metafile format, but are preceded by an additional 8- or 16-byte header that allows the position of the metafile on the Clipboard viewer.
		Enhanced metafile files are a "new and improved" 32-bit revision of the standard metafile.

	Metafiles & Printing
		Unfortunately few Windows applications that support metafiles, also support metafiles that contain OpenGL (you also have to consider that this support is only in NT 4.0 or later, and isn’t even planned for Windows 98).
		Since enhanced metafiles are supported natively by the clipboard, this would be an ideal way to cut and paste OpenGL images from one application to another.
		Microsoft Office ships with hundreds of windows metafiles (.wmf extension) for use as clipart, but these are not the same as enhanced metafiles.

	Companion Software - Windows Metafile FAQ
		Typically, a metafile is made up of commands to draw objects such as lines, polygons and text and commands to control the style of these objects.
		But as soon as the user tries to edit (or ungroup) the metafile, then they convert it to their own internal format and that's where the idiosyncracies occur.
		Metafile Companion from Companion Software is about as close as you come to a "perfect" metafile editor.

	Enhanced Metafile Operations
		Pass the function a handle to the enhanced metafile, without being concerned with the format of the enhanced metafile records.
		However, it is sometimes desirable to enumerate the records in the enhanced metafile to search for a particular GDI function and modify the parameters of the function in some manner.
		To determine whether a palette is stored in an enhanced metafile, retrieve the metafile header and examine the appropriate member.

	How to Create & Play Enhanced Metafiles in Win32
		These new metafiles address developer's need for device independence without requiring a separate code path, which was a requirement of the older style metafiles.
		The number of device units on the metafile can be determined by using the pixel/mm ratio of the reference DC and the metafile device size given in the lpRect parameter.
		During the recording of the metafile, the mapping mode, window extents and origin, and viewport extents and origin combine to map logical units to device units on the metafile device.

	PRB: Using Enhanced Metafiles in COleServerItem
		Enhanced metafiles do not appear in a non-active state in a OLE client when they are used by the server to render the image.
		When COleServerItem::OnDraw is called, the DC passed is for a standard metafile, not an enhanced metafile, so the rendering into the DCneeds to be limited to items understood by a standard metafile.
		If your server is using enhanced metafiles, and the client is asking it to render to an standard metafile, you need to make a conversion.

	Copying Spectra
		There are 2 types of Enhanced metafiles available from the Edit menu, one of which requires a printer "device context".
		When a metafile is copied to the clipboard, the coordinates are expressed as integers (because you can't have a fraction of a pixel) and this can cause roundoff errors if the number of points in the spectrum being copied exceeds the number of pixels.
		Any text displayed on the screen (with Ctrl-B command) is not copied when copying as a standard metafile or as a PICT file, because placing the spectrum into the clipboard replaces the text that was there.

	Systat Software Inc. - PeakFit - HTML Help
		Windows metafiles consist of a series of Windows graphics vector instructions which are intended to reproduce the original image.
		Windows Metafiles offer superior resolution and scaling, although the program importing the image may have difficulties in properly rendering text elements such as superscripts, subscripts, and symbols in their proper positions.
		When a metafile image is placed and scaled, the software importing the file may not preserve the proper character spacing across the separate text segments.

		There is much you can learn about metafiles and how they work by studying the code, but not too much that you must learn in order to to use it.
		Because the enhanced metafile format is standardized, pictures that are stored in this format can be copied from one application to another; and, because the pictures are truly device independent, they are guaranteed to maintain their shape and proportion on any output device."
		When a metafile is being built, data is written to a special "device context", a structure that defines the characteristics of a particular device.

	Windows Enhanced MetaFiles: Introduction (Site not responding. Last check: 2007-10-05)
		The Enhanced MetaFile (EMF) format is an extension of the Windows metafiles format developed for use with 32 bit Windows applications.
		Supplementary specifications for metafiles saved as enhanced metafiles are stored in the ENHMETAHEADER structure at the beginning of the metafile.
		Enhanced metafiles store device context coordinates relative to a reference DC (device context).

	Enhanced Metafile Creation
		Most applications store pictures permanently and therefore create an enhanced metafile that is stored on a disk; however, there are some instances when this is not necessary.
		A metafile device context is unique in that it is associated with a file rather than with an output device.
		When the system processes a GDI function that received a handle to a metafile device context, it converts the GDI function into an enhanced-metafile record and appends the record to the end of the enhanced metafile.

	Special Considerations and Incompatibilities for pasting bar codes into documents
		The Windows Metafile format is ideal for creating bar codes however the new Enhanced Metafile format has several major design flaws that render it inadequate for creating extremely high resoliution graphics (as required when printing bar codes).
		Metafile images are device independent, scaleable images that consist of drawing instructions used internally by Windows to reproduce an image in a manner that uses the highest resolution of the device that the image is being printed on.
		When you paste a Metafile bar code produced by B-Coder into a graphics or drawing program that only has the capability of working with bitmap files (.BMP) such as the PaintBrush program that comes with Windows, your bar code will be automatically converted from a Windows Metafile format to a bitmap format.

	I Never Metafile I Didn't Like (Site not responding. Last check: 2007-10-05)
		Metafiles are one of two fundamental ways of representing an image.
		More recently, the Enhanced MetaFile Plus (EMF+) format was developed to support new drawing commands in GDI+; it too uses the EMF extension.
		This "size" is not relevant to anything in the physical world, as the image can still be displayed at any desired size, but a metafile's size can be assigned to define its intended display size or to relate the arbitrary units in the metafile to real world units (for example, in an engineering drawing).

	Dr. Dobb's \| Documenting the Graphic Import Filter Interface \| April 15, 2003
		Although useful in their own right, metafiles are generally difficult to manage and are best suited for vector-based graphics and drawing.
		Drawing the metafile or extracting the embedded raster bitmap image turns out to be the most difficult process after the import.
		Armed with a little knowledge regarding metafiles, it is possible to enumerate the embedded metafile operations and directly extract the bitmap handle [5].

	Windows Metafile WMF Enhanced Metafile EMF
		WMF (Windows Metafile) and EMF (Enhanced Metafile) are the core display formats of the Windows operating environment and the native graphics formats for MS Office applications.
		EMF is the newer enhanced 32-bit format and is slowly gaining acceptance.
		Developers use metafiles and the underlying GDI code to render application output to the screen or send it to the printer.

	libEMF: Enhanced Metafile Library
		The Enhanced MetaFile (EMF) is one of the two color vector graphics format which is "vectorially" understood by SO/OO.
		The third argument gives the size and position of the metafile; since SO/OO ignores the position, the first two values should be zero; the second pair of values should give the desired physical width and height of the drawing in units of 1/1000-th centimeters.
		The last argument to the creation routine is the description of the metafile; by convention, this consists of two null-terminated strings with an extra '\0' at the end.

	What is EMF? - a definition from Whatis.com - see also: raw spool files, Enhanced MetaFile
		EMF (Enhanced MetaFile) and raw are terms for spool file formats used in printing by the Windows operating system.
		When a print job is sent to the printer, if it is already printing another file, the computer reads the new file and stores it, usually on the hard disk or in memory, for printing at a later time.
		The EMF format is the 32-bit version of the original Windows metafile (WMF) format.

	Embed a bitmap in an enhanced metafile
		There may be times where we want to embed a bitmap into an enhanced metafile for portability reasons.
		A good example is a drawing program where you want to export drawing items, where bitmap objects are particular type of drawing objects, to an enhanced metafile to be placed into other programs as a unit.
