Windows Metafile Formats (WMF and EMF)

The Windows Metafile (WMF and EMF) formats are vector formats that may or may not also contain a raster image.

EMF/WMF Vector files can be read and written as raster images in the Imaging Pro toolkits. They can be read and written as vector images in the Document and Medical Imaging toolkits.

It is possible to speed up the loading of large WMF or EMF files. For more information, refer to Using Filter Data to Speed up Loading Large Files.

File constants associated with this file format are:

Constant	Read Support	Write Support	Description
FILE_WMF	Yes	Yes	[15] Windows Metafile.
FILE_EMF	Yes	Yes	[116] Windows Enhanced Metafile.

When WMF and EMF files are rasterized, they are either 8 or 24 BPP.

The following table indicates which objects LEADTOOLS can load and which objects it can save:
