Update of /cvsroot/libwpg/libwpg/src/conv/raw In directory sc8-pr-cvs6.sourceforge.net:/tmp/cvs-serv14544/src/conv/raw Modified Files: main.cpp Log Message: - important records for WPG2 (pen, brush, lines, curve) - the listener is now PaintInterface, using PostScript-like rendering model - simplified SVG generation (due to the above PaintInterface) - fixed coding style to follow libwpd (tab-indentation, camelcase function names, correct file names, ...) - fixed FSF address - added notices on implementation details (first commit for my Google Summer of Code project) Index: main.cpp =================================================================== RCS file: /cvsroot/libwpg/libwpg/src/conv/raw/main.cpp,v retrieving revision 1.7 retrieving revision 1.8 diff -u -d -r1.7 -r1.8 --- main.cpp 1 Feb 2005 17:15:56 -0000 1.7 +++ main.cpp 17 Jun 2006 08:11:53 -0000 1.8 @@ -1,128 +1,130 @@ -/* libwpg - * Copyright (C) 2004 Marc Oude Kotte (ma...@so...) - * Copyright (C) 2005 Fridrich Strba (fri...@bl...) - * - * This library is free software; you can redistribute it and/or - * modify it under the terms of the GNU Library General Public - * License as published by the Free Software Foundation; either - * version 2 of the License, or (at your option) any later version. - * - * This library is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
