There are references to Windows Metafiles or Enhanced Metafiles, being both propietary formats with technical dependence of the Windows systems. The natural alternative for these sections would be ISO/IEC 8632 Standard: “Computer Graphics Metafile”, an independent ISO format of the platform.
It is clear that OpenXML does not have requirements of implementation for EMF or WMF. The referred section (6.2.3.17) allows the use of any type of graphical formats. The potential values are “Bitmap”, “Pict”, “PictOld”, “PictPrint”, and “PictScreen” which can be mapped to any format of image, particularly to Computer Graphics Metafile.
WMF and EMF are presented like possible values in an enumeration.

It is requested to add an example of configuration of a file that includes an image in format ISO 8632.

Proposed Disposition of DIS 29500 Comment UY-0005 (Modified: 2008-01-13) Agreed; the intention was that all image formats are allowed, but the documentation referenced WMF and EMF, which was a mistake. For the definition of ST_CF in (Part 4, §6.4.3.1, page 4,955­4,956), it should be clear that this is an open simple type that allows for application’s to specify any values they would like. There was a set of enumeration values provided for guidance, but any specific MIME type could also be used (for example, for TIFF; PNG; JPEG). The errors in the documentation occurred on the descriptions of a couple of the example enumeration values, and will be corrected as noted below. With respect to Part 4, §6.4.2.10, the CF element is the only element that references the ST_CF simple type as defined in §6.4.3.1 and will be affected by the changes to ST_CF specified below. However, no corrections are needed in §6.4.2.10 directly, as it doesn’t specify the image types. The following changes will be made: Part 4, §6.2.3.17, page 4,896, line 13 Enumeration Value Description Bitmap (Bitmap Image) Specifies that a bitmap shall should be requested. EnhancedMetaFile ( Enhanced Metafile Image Metafile Picture ) Specifies that an enhanced metafile shall be requested Specifies that a metafile (non-raster) image should be requested . Jpeg (JPEG) An image which should use the JPEG format. Picture (Other Image) Specifies that any image format may be requested. [Example: PNG or CGM (ISO/IEC 8632). end example] Png (Portable Network Graphics) An image which should use the Portable Network Graphics format. Part 4, §6.4.3.1, page 4,955­4,966 Enumeration Value Description Bitmap (Bitmap) Bitmap. Jpeg (JPEG) An image which should use the JPEG format. Enumeration Value Description Pict ( EMF Picture ) Enhanced metafile Any picture format . [Example: SVG or JPEG. end example] PictOld ( WMF Picture Old ) Windows Metafile Any picture format, but preferably one that is more likely to be supported by legacy applications . PictPrint (Printer Picture) An image rendered using the default printer’s settings. This is typically of higher resolution and scaled differently compared to a picture created for on-screen rendering. PictScreen (Screen Picture EMF ) An image rendered using screen settings. This is typically lower resolution than an image created for printing. Png (Portable Network Graphics) An image which should use the Portable Network Graphics format.
