I would really appreciate some help with this little problem I have, it may only be a click away somewhere in a menu - perhaps someone can help. The application I'm using is Inkscape and I'm trying to find a way to quickly merge the overlapping nodes of a *single* object. Because the shape's nodes have been randomly jittered they are now overlapping each other - which is exactly what I want but not the white 'negative' spaces. I would like to achieve the result shown on the right of the picture (this was done outside Inkscape using Photoshop) perhaps you can help?
