Ok,It working fine.
void write_coordinates(SPObject *obj,FILE *fp) { if(!SP_IS_ITEM(obj)) return ;
Inkscape::XML::Node *path= obj->getRepr(); if (path->name() != Glib::ustring("svg:path")) return;
gchar const *svgd = path->attribute("d");
if ( path != NULL ) { Geom::PathVector pathv = sp_svg_read_pathv(svgd); for (Geom::PathVector::const_iterator pit = pathv.begin(); pit != pathv.end(); ++pit) { Geom::Point p = pit->front().initialPoint(); fprintf(fp,"MoveTo: %f,%f \n ", p[0],p[1]);
for (Geom::Path::const_iterator cit = pit->begin(); cit != pit->end_closed(); ++cit) { if(Geom::LineSegment const *line_segment = dynamic_cast<Geom::LineSegment const *>(&*cit)) { // don't serialize stitch segments if (!dynamic_cast<Geom::Path::StitchSegment const *>(&*cit)) { fprintf(fp,"LineTo: %f,%f \n ", (*line_segment)[1][0], (*line_segment)[1][1] ); } } else if (Geom::CubicBezier const *cubic_bezier = dynamic_cast<Geom::CubicBezier const*>(&*cit)) { fprintf(fp,"Curve To1: %f,%f \n ",(*cubic_bezier)[1][0], (*cubic_bezier)[1][1]); fprintf(fp,"Curve To2: %f,%f \n ",(*cubic_bezier)[2][0], (*cubic_bezier)[2][1]); fprintf(fp,"Curve To3: %f,%f \n ",(*cubic_bezier)[3][0], (*cubic_bezier)[3][1]);
} else if (Geom::QuadraticBezier const *Qcubic = dynamic_cast<Geom::QuadraticBezier const*>(&*cit)) { fprintf(fp,"QuadraticBezier \n "); } } pit->closed(); }
fprintf(fp,"PATH2: %s \n ", svgd ); } } How i get each parameter of gchar const *svgd = path->attribute("d"); here i parse with above function but gives screen coordinate instead of the svg file coordinate. Please let me know how can i get original coordinate which i write in file in variable.(actually i don't want to parse string)Is there any function in inkscape ,so i can get original value directly.
Thanks

Ok,Its working with following way.I used SPObject *obj = doc->getRoot(); insted of doc->getRoot()->firstChild(); But it give outPut Four line ,The first line repeat 2 times. http://old.nabble.com/file/p32080719/Data.txt Data.txt why its happen ,is there any error in code ?
void write_coordinates(SPObject *obj,FILE *fp) { if(!SP_IS_ITEM(obj)) return ;
Inkscape::XML::Node *newitem= obj->getRepr(); Inkscape::XML::Node *path = sp_repr_lookup_name(newitem, "svg:path",-1);
if ( path != NULL ) { gchar const *svgd = path->attribute("d"); fprintf(fp,"PATH2: %s \n ", svgd ); }}
void visit_all_objects(SPObject *obj,FILE *fp) { if (obj == NULL) return;
write_coordinates(obj, fp); // write object's coordinates to a file here SPObject *child = obj->children; for (; child; child = child->next) { visit_all_objects(child,fp); } } bool sp_file_save_as(Gtk::Window &parentWindow, gpointer /*object*/, gpointer /*data*/) { if (!SP_ACTIVE_DOCUMENT) return false;
SPDocument *doc = inkscape_active_document(); SPObject *obj = doc->getRoot();//->firstChild(); FILE *fp = fopen("D:\\Data.txt","w"); visit_all_objects(obj, fp); fclose(fp); return true;}
One more things , How i get each parameter of gchar const *svgd = path->attribute("d"); here i try with following function but gives screen coordinate instead of the svg file coordinate. Geom::PathVector pathv = sp_svg_read_pathv(svgd); Please let me know how can i get original coordinate which i write in file in variable.(actually i don't want to parse string)Is there any function in inkscape ,so i can get original value directly.

I try to implement your code in another following way .
The Input file name :drawing-1.svg http://old.nabble.com/file/p32072659/drawing-1.svg drawing-1.svg
with above code I can get only One line coordinate instead of the two line.Please check the attached output file The OutPut file name :Data1.txt http://old.nabble.com/file/p32072659/Data1.txt Data1.txt
Now how can i get next line coordinate ?
This cannot be done this way. You must define a recursive function (a function that calls itself) like I told you earlier. Please tell me what was wrong with the code I posted. If it gave an error, please post the error.
I guess the previous code could have crashed, so here is another attempt:
void write_coordinates(SPObject *obj) { Inkscape::XML::Node *path = obj->getRepr(); gchar const *svgd = path->attribute("d"); if (svgd) fprintf(fp,"PATH2: %s \n ", svgd ); }
void visit_all_objects(SPObject *obj, FILE *fp) { if (obj == NULL) return;
write_coordinates(obj, fp); // write object's coordinates to a file here SPObject *child = obj->children; for (; child; child = child->next) { visit_all_objects(child); } }
bool sp_file_save_as(Gtk::Window &parentWindow, gpointer /*object*/, gpointer /*data*/) { if (!SP_ACTIVE_DOCUMENT) return false;
SPDocument *doc = inkscape_active_document(); SPObject *obj = doc->getRoot()->firstChild();
FILE *fp = fopen("D:\Data.txt","a"); visit_all_objects(obj, fp); fclose(fp);
return true; }
