Basic Usage

Drawing a Rectangle

import { Canvas, Paint, Color, Size, Point } from "termestry";

const myPaint = new Paint(
  Color.RED /* stroke color */,
  Color.BLUE /* fill color */
);

const myCanvas = new Canvas(myPaint); /* create a canvas with the paint */

const size = new Size(10, 10);

myCanvas.rect(
  Point.centerFor(size),
  size
); /* draw a rectangle at the center of the screen */

myCanvas.draw(); // draw the canvas

Creating a stick figure

import { Paint, Color, Size, Point, Canvas } from './src/index.js';

const myPaint = new Paint(
    Color.Red, /* stroke color */
    Color.None, /* fill color */
);
const myCanvas = new Canvas(myPaint); /* create a canvas with the paint */

// What is a stick figure?
//  O <- A circle (head)
// --- <- A long line (arms)
//  | <- A line (body)
// / \ <- Two lines (legs)

const head = new Size(6, 6);
const body = new Size(1, 5);
const arms = new Size(5, 1);
const legs = new Size(5, 2);

const center = Point.centerFor(head);

// The head
myCanvas.ellipse(
    center, // Where to draw the head
    head.width / 2, // The X radius
    head.height / 2, // The Y radius
    0, // The rotation
    0, // The start angle
    2 * Math.PI, // The end angle (2 * PI is a full circle)
);

// The arms
let arms_subpath = myCanvas.subpathAt(
    new Point(
        center.x - arms.width / 2,
        center.y + head.height - arms.height
    )
); // Create a subpath at the center of the head

arms_subpath.lineTo(
    new Point(
        center.x + arms.width / 2,
        center.y + head.height - arms.height
    )
); // Draw the arms

// The body
let body_subpath = myCanvas.subpathAt(
    new Point(
        center.x,
        center.y + head.height / 2
    )
); // Create a subpath at the bottom of the head

body_subpath.lineTo(
    new Point(
        center.x,
        center.y + head.height / 2 + body.height
    )
); // Draw the body

// The legs
let legs_subpath = myCanvas.subpathAt(
    new Point(
        center.x,
        center.y + head.height / 2 + body.height
    )
); // Create a subpath at the bottom of the body

legs_subpath.lineTo(
    new Point(
        center.x - legs.width,
        center.y + head.height / 2 + body.height + legs.height
    )
); // Draw the left leg

let legs_subpath_2 = myCanvas.subpathAt(
    new Point(
        center.x,
        center.y + head.height / 2 + body.height
    )
); // Create a subpath at the bottom of the body

legs_subpath_2.lineTo(
    new Point(
        center.x + legs.width,
        center.y + head.height / 2 + body.height + legs.height
    )
); // Draw the right leg

myCanvas.draw(); // Draw the canvas
