DWF Format (DWF)

DWF is a binary file format used by AutoDesk AutoCAD for storing DWG files on the World Wide Web. DWF is a 2D, vector-based description of drawings and illustrations.

LEADTOOLS supports DWF versions 4, 5, 5.5 and 6.

This file format supports loading with different units.

This file format is not supported in the Imaging Pro toolkits. Read and write support for this format is provided in the Document and Medical Imaging toolkits.

DWFX

DWFX is an Autodesk DWF XPS Document. Autodesk has teamed with Microsoft to seamlessly integrate DWF technology with Windows Vista using the XML Paper Specification (XPS). Read and write support for this format is provided in the Document and Medical Imaging toolkits.

The file constants associated with these file formats are:

Constant Read Support Write Support Description
FILE_DWF Yes Yes [145] AutoDesk AutoCAD for storing DWG files on the World Wide Web.
FILE_DWF_TEXT_AS_POLYLINE N/A Yes [297] AutoDesk AutoCAD for storing DWG files on the World Wide Web. Use this format to save DWF and have Text objects converted to Polyline objects in the output file.
FILE_DWFX Yes Yes [376] An Autodesk DWF XPS Document. Files can be opened with the XPS Viewer

When DWF files are rasterized, they are 24 BPP.
