File Formats: Windows Metafile Format (WMF)

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 non-vector toolkits. Vector read/write support for these formats is provided in the LEADTOOLS Vector toolkits and is unlocked when the Vector features are unlocked. For more information on available LEADTOOLS products, refer to Topic Selection or contact LEAD.

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.

Note:

When working with LEADTOOLS annotations (rather than image files), you can save the annotations as WMF or EMF files containing vector graphics that can be used in other applications.
