$c = new CairoContext($s);

$c->setSourceRgb(000);
$c->paint();

// Move 10 pixels across, and 10 pixels down
$c->moveTo(1010);
$c->lineTo(9090);
$c->setLineWidth(2);
$c->setSourceRgb(111);
$c->stroke();

// Move 90 pixels across, and 10 pixels down
$c->moveTo(9010);
$c->lineTo(1090);

cairo_paint($c);

// Move 10 pixels across, and 10 pixels down
cairo_move_to($c1010);
cairo_line_to($c9090);
cairo_set_line_width($c2);
cairo_set_source_rgb($c111);
cairo_stroke($c);

// Move 90 pixels across, and 10 pixels down
cairo_move_to($c9010);
cairo_line_to($c1090);
cairo_set_line_width($c2);
cairo_set_source_rgb($c111);
