1 /** 2 * \file lpe-framework.h 3 * \brief A framework for writing an Inkscape Live Path Effect toy. 4 * 5 * Instead of using the standard toy framework, one can use this LPE 6 * framework when creating an LPE for Inkscape. When new 2geom functions 7 * are required for the LPE, adding this functionality directly in Inkscape 8 * greatly increases compile times. Using this framework, one only has to 9 * rebuild 2geom, which speeds up development considerably. (Think about 10 * how much of Inkscape will have to be rebuild if you change/add something 11 * in point.h ...) 12 * An example of how to use this framework is lpe.test.cpp. 13 *//* 14 * Copyright 2009 Johan Engelen <goejendaagh@zonnet.nl> 15 * 16 * This library is free software; you can redistribute it and/or 17 * modify it either under the terms of the GNU Lesser General Public 18 * License version 2.1 as published by the Free Software Foundation 19 * (the "LGPL") or, at your option, under the terms of the Mozilla 20 * Public License Version 1.1 (the "MPL").
