[cairo] Question about cairo_fill_preserve

[Meryl Silverburgh]

hi,

I have a question about cairo_fill_preserve.

If I use cairo_line_to(), and cairo_move_to() to draw something like this:
|       |
---------
|       |
---------

I see it when i use 'cairo_stroke_preserve()'

But what if I want to fill the bottom rectangle , i try using
cairo_fill_preserve(), but nothing appear.

Here is my example (based on the hello.c in cairo)

#include <cairo.h>

int
main (int argc, char *argv[])
{
        cairo_surface_t *surface;
        cairo_t *cr;

        surface = cairo_image_surface_create (CAIRO_FORMAT_ARGB32, 1240, 180);
        cr = cairo_create (surface);


	cairo_set_source_rgb (cr, 0.8, 0.0, 0.0);


	cairo_move_to(cr, 1002, 0);
	cairo_line_to(cr, 1002, 131);


	cairo_move_to(cr, 1002, 131);
	cairo_line_to(cr, 0, 131);

	

	cairo_move_to(cr, 0, 131);
	cairo_line_to(cr, 0, 0);



	cairo_move_to(cr, 0, 0);
	cairo_line_to(cr, 0, 125);



	cairo_move_to(cr, 0, 125);
	cairo_line_to(cr, 1002, 125);


	cairo_move_to(cr, 1002, 125);
	cairo_line_to(cr, 1002, 0);

	/* works */
	/*  cairo_stroke_preserve(cr); */

	/* nothing shows up */
	cairo_close_path (cr);
	cairo_fill_preserve(cr);

        cairo_destroy (cr);
        cairo_surface_write_to_png (surface, "hello.png");
        cairo_surface_destroy (surface);

        return 0;
}
