Class DwgFileV12Reader

java.lang.Object

org.gvsig.dwg.lib.readers.DwgFileV12Reader

All Implemented Interfaces:

IDwgFileReader

public class DwgFileV12Reader
extends java.lang.Object
implements IDwgFileReader

Reads version 12 dwg files. DWG 13 and DWG 12 are very different formats (nor do DWG 13-14 and 2000). Thats the reason why this IDwgFileReader is very different from the rest. Documentation of reverse engineering of the format: http://www.iwriteiam.nl/DWG12.html
