The Enhanced Metafile (EMF) format is a superset of [intlink id=”2989″ type=”post”]WMF[/intlink]. While WMF is a safe choice and supported consistently in virtually all graphical Windows applications, EMF offers more. It can be customized, is extensible and has any more features. All of these benefits also make it a riskier choice since they can introduce incompatibilities between EMF files and applications that support EMF. Gains from EMF include support for scaling, Bezier curves, cropping, improvements in color support and device independence. It also includes support for meta-data which allows built-in descriptions that are saved with the file. Developers can modify the original EMF specification to add functionality or to meet specific needs. This modification is what leads to incompatibilities between different types of EMF pictures.
- EMF is the enhanced 32-bit metafile format while WMF is the well-established 16-bit format and excellent application support at all levels within the 16-bit and 32-bit Microsoft Windows platforms
- Application support for reading EMF is not well established yet but is gaining momentum. It adds support for curves, cropping, extremely large drawings
- WMF and EMF both support vector graphics, raster images, text and fonts
- Visual Integrity software can overcome inherent limitations of the WMF format including no support for curves, cropping, extremely large drawings by emulating these features in the output
- META FLY can convert both 16-bit WMF and 32-bit EMF to other file formats.
- If you have a choice and do not require the advanced graphical features that EMF supports, using WMF as your input format is a safer choice.
