# Alt1lib The base library for Alt1 apps to communicate with the Alt1 API. For intellisense based IDE's it will also add intellisense declarations for the global `alt1` object inside the Alt1 browser. ## Installation ```sh npm install alt1 ``` # Usage ```js import * as a1lib from "alt1/base"; // Captures a 400x400 rectangle starting at position 100,100 from the top-left of the game area // imgref now contains a reference to the image (in this case still in Alt1 memory) var imgref = a1lib.capture(100,100,400,400); // Retrieve our raw pixel data so we can directly read it var imagebuffer = imgref.toData(); // Show the image by adding it to the DOM (for debugging) imagebuffer.show(); ```
