'How to access Cairo drawn path?

I'm using cairomm to draw object.

#include "cairo/cairo.h"


int main()
{
    cairo_surface_t *surface;
    cairo_t *cr1;

    double width = 3840;
    double height = 2160;

    surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32, width, height);
    cr1 = cairo_create (surface);

    cairo_move_to(cr1, 0, 0);
    cairo_set_source_rgb(cr1, 1, 1, 1);
    cairo_set_line_width(cr1, 50.0);
    cairo_move_to(cr1, 0, 0)
    cairo_line_to(cr1, width, height)
    cairo_stroke();


    return 0;
}

Above code makes a line. I want to manipulate(to move, to extend, etc..) the line after the line is created. Are there any solutions?

c++cairo
