From 655fcebb893b44019786e7e9c7229975024f4d97 Mon Sep 17 00:00:00 2001 From: "Johan B. C. Engelen" Date: Sat, 22 Mar 2008 19:11:02 +0000 Subject: * add RegisteredTransformedPoint widget, that transforms the point before displaying/writing. This in order to keep them in SVG coordinate system in XML, but in canvas coord system in the spinbox * move Geom::Point XML writing to central place in ostringstream * add verb for LPE context (bzr r5165) --- .../parameter/pointparam-knotholder.cpp | 204 +++++++++++++++++++++ 1 file changed, 204 insertions(+) (limited to 'src/live_effects/parameter/pointparam-knotholder.cpp') diff --git a/src/live_effects/parameter/pointparam-knotholder.cpp b/src/live_effects/parameter/pointparam-knotholder.cpp index 12d081703..fa042be5a 100644 --- a/src/live_effects/parameter/pointparam-knotholder.cpp +++ b/src/live_effects/parameter/pointparam-knotholder.cpp @@ -1,3 +1,206 @@ +<<<<<<< .mine +#define INKSCAPE_LPE_POINTPARAM_KNOTHOLDER_C + +/* + * Container for PointParamKnotHolder visual handles + * + * Authors: + * Johan Engelen + * + * Copyright (C) 2008 authors + * + * Released under GNU GPL, read the file 'COPYING' for more information + */ + +#include "live_effects/parameter/pointparam-knotholder.h" +#include "live_effects/lpeobject.h" +#include "document.h" +#include "sp-shape.h" +#include "knot.h" +#include "knotholder.h" +#include "knot-holder-entity.h" + +#include +#include +#include <2geom/point.h> +#include <2geom/matrix.h> +#include "svg/stringstream.h" +#include "xml/repr.h" + +class SPDesktop;
