save

Example: Save and Restore:

public static int main (string[] args) {
	// Create a context:
	Cairo.ImageSurface surface = new Cairo.ImageSurface (Cairo.Format.ARGB32, 80, 80);
	Cairo.Context context = new Cairo.Context (surface);

	// Draw a rectangle:
	context.rectangle (10, 10, 50, 50);

	// Style settings:
	context.set_source_rgba (0, 0, 0, 1);
	context.set_line_width (8);

	// Change some style settings inside save/restore:
	context.save ();
	context.rotate (0.16);
	context.set_source_rgba (1, 0, 0, 1);
	context.fill ();
	context.restore ();

	// We are using the previous style settings again:
	context.rectangle (20, 20, 50, 50);
	context.fill ();

	// Save the image:
	surface.write_to_png ("img.png");

	return 0;
}
