DXF (Drawing Interchange Format) was first introduced by AutoDesk AutoCAD, and is one of the most widely used CAD/CAM/CAE applications in the world. DXF is very popular and is supported by most 3D formats on PC platforms.
A DXF file is an ASCII file containing 2D and 3D components representing a drawing. Those components are known as Entities. The DXF file can represent almost any CAD drawing using those entities, and can connect a group of entities together (such as windows, doors, etc.) and use them later in the file. The DXF file has seen many changes through the years, from version 2.6 to the latest release version 14. However, the latest release of AutoCAD still manages to open files created with any of the earlier versions.
Blaze ImgConvert supports all current variations of the DXF format (versions 2.6, 9, 10, 11, 12, 13, 14) and loads the following objects: LAYER, BLOCK, LINE, 3DFACE, TRACE, SOLID, ARC, CIRCLE, ELLIPSE, POINT, LWPOLYLINE, POLYLINE, SPLINE, INSERT, TEXT, MTEXT, DIMENSION, LEADER, TOLERANCE, ATTRIB, ATTDEF, 3DSOLID, VERTEX, and IMAGE.
LEADTOOLS can save the following objects: POINT, LINE, SOLID, 3DFACE, POLYLINE, VERTEX, ELLIPSE, CIRCLE, ARC, TEXT, BLOCK, INSERT, and IMAGE.
Blaze ImgConvert currently does not support the following objects: ACAD_PROXY_ENTITY, BODY, HATCH, MLINE, OLEFRAME, OLE2FRAME, RAY, REGION, SHAPE, VIEWPORT, and XLINE.
For DXF files, you can read the following bits per pixel: 8.
