Example

This example is not tested
extern crate piston;
extern crate graphics;
extern crate glutin_window;
extern crate opengl_graphics;

use piston::window::WindowSettings;
use piston::event::*;
use glutin_window::GlutinWindow as Window;
use opengl_graphics::{GlGraphics, OpenGL, Texture};
use graphics::{Image, clear, default_draw_state};
use graphics::rectangle::square;
use std::path::Path;

fn main() {
	let opengl  = OpenGL::_3_2;
	let mut gl  = GlGraphics::new(opengl);
	let window  = Window::new(
			opengl,
			WindowSettings::new(
				"Example",
				[600, 400]
			).exit_on_esc(true));

	//Create the image object and attach a square Rectangle object inside.
	let image   = Image::new().rect(square(0.0, 0.0, 200.0));
	//A texture to use with the image
	let texture = Texture::from_path(Path::new("Example.png")).unwrap();

	//Main loop
	for e in window.events() {
		if let Some(r) = e.render_args() {
			gl.draw(r.viewport(), |c, gl| {
				//Clear the screen
				clear([0.0, 0.0, 0.0, 1.0], gl);
				//Draw the image with the texture
				image.draw(&texture, default_draw_state(), c.transform, gl);
			});
		}
	}
}
