| Format introduction | DWG is a proprietary binary file format used for storing two- and three- dimensional design data and metadata. It is the native format for several CAD packages including DraftSight, AutoCAD, IntelliCAD, Caddie and Open Design Alliance compliant applications. In addition, DWG is supported non-natively by many other CAD applications. | Truevision TGA, often referred to as TARGA, is a raster graphics file format created by Truevision Inc. It was the native format of TARGA and VISTA boards, which were the first graphic cards for IBM-compatible PCs to support Highcolor/truecolor display. |
| Technical details | DWG contains all the pieces of information a user enters, such as: Designs, Geometric data, Maps, Photos. The .dwg file format is one of the most commonly used design data formats, found in nearly every design environment. The DWG technology environment contains the capability to mold, render, draw, annotate, and measure. | The format can store image data with the maximum 24 bits of RGB and an extra 8-bit alpha channel. Color data can be color-mapped, or in direct color or truecolor format. Image data may be stored raw, or optionally, a lossless RLE compression similar to PackBits can be employed. |
