Windows Metafile Format (WMF) and Windows Enhanced Metafile Format (EMF) are native Windows formats used primarily for vector graphics, such as clip art, shared between Windows applications. Metafiles may contain raster image information; InDesign recognizes the vector information and provides limited support for raster operations. Color support is limited to 16‑bit RGB, and neither format supports color separations. Metafile formats are not an ideal choice for commercially printed or online documents; they provide acceptable quality only when printed on low-resolution or non-PostScript printers from a Windows desktop.
