    The CanvasRenderingContext2D.translate() method of the Canvas 2D API adds a translation transformation by moving the canvas and its origin x horizontally and y vertically on the grid.

    Syntax

    void ctx.translate(x, y);

    Parameters

    x
    Distance to move in the horizontal direction.
    y
    Distance to move in the vertical direction.

    Examples

    Using the translate method

    This is just a simple code snippet which uses the translate method.

    HTML

    <canvas id="canvas"></canvas>

    JavaScript

    var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");

ctx.translate(50, 50);
ctx.fillRect(0,0,100,100);

// reset current transformation matrix to the identity matrix
ctx.setTransform(1, 0, 0, 1, 0, 0);

    Edit the code below and see your changes update live in the canvas:

    Playable code
    <canvas id="canvas" width="400" height="200" class="playable-canvas"></canvas>
<div class="playable-buttons">
  <input id="edit" type="button" value="Edit" />
  <input id="reset" type="button" value="Reset" />
</div>
<textarea id="code" class="playable-code">
ctx.translate(50, 50);
ctx.fillRect(0,0,100,100);
ctx.setTransform(1, 0, 0, 1, 0, 0);</textarea>

    var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;

function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);
  eval(textarea.value);
}

reset.addEventListener("click", function() {
  textarea.value = code;
  drawCanvas();
});

edit.addEventListener("click", function() {
  textarea.focus();
})

textarea.addEventListener("input", drawCanvas);
window.addEventListener("load", drawCanvas);
