DWF Format (DWF)

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 non-vector toolkits. Read and write support for this format is provided in the LEADTOOLS Vector Imaging Pro toolkit and is unlocked when the Vector features are unlocked.

LEADTOOLS supports loading this format as raster image, vector or SVG (Scalable Vector Graphics) document.

DWFX

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

LEADTOOLS supports loading this format as a raster image, vector image, or SVG (Scalable Vector Graphics) document.

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.
