DWG Format (DWG)

DWG is a binary file format used by AutoDesk AutoCAD. It can contain 2D or 3D objects and offers compression and a CRC check for internal data.

LEADTOOLS supports DWG 12, 13, 14, 15 (DWG2000), and 18 (DWG2004) files.

This file format supports loading with different units and viewing multi-degree spline.

This file format is not supported in the non-vector toolkits. Read support for this format is provided in the LEADTOOLS Vector Imaging Pro toolkit and is unlocked when the Vector features are unlocked.

The default extension used by this format is: DWG.

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

LEAD supports the object types listed above, as well as, layers and the grouping of objects. Embedded raster objects are not supported.

File constants associated with this file format are:

Constant	Read Support	Write Support	Description
FILE_DWG	Yes	No	[124] AutoDesk AutoCAD binary format.

When DWG files are rasterized, they are 24 BPP.
