Microsoft developed EMF files, or Enhanced Metafiles, to store large amounts of image data for high-quality printing. An EMF is an improved WMF file (Windows Metafile), which supports 32-bit instead of 16-bit graphics. The result of the improvement is that the image is crisper, cleaner, and has more varied colors than the 16-bit counterparts. Both WMF and EMF are metafiles that enable applications to render graphics. However, EMF has more calling functions and supports bitmap and vector graphics. Newer devices use EMF files that permit graphic devices to understand and render 32-bit files. An EMF file is ideal to use when platforms are incompatible, as the EMF file allows portability between two programs. Programs that can open EMF files include Microsoft Publisher, Microsoft Word, and QuarkXpress.
