An image
Example
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); }); } } }
