Create A Rotatable & Scalable Photo Grid With Canvas Table

Canvas Table is a simple jQuery based image editing tool to dynamically generate a customizable photo grid using HTML5 canvas.

Click/tap on the photo grid to rotate, scale, and/or pan around an image and then click the Generate button to render a new photo grid that is downloadable as a PNG image (base64 encoded).

How to use it:

1. Create an empty <canvas /> element on which the plugin renders the image editing area.

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

2. Create the Scale and Rotate slider controls.

<label for="scaleRange">Scale</label>
<input id="scaleRange" type="range" disabled="disabled" min="0.1" max="2" step="0.1" value="1" />

<label for="rotateRange">Rotate</label>
<input id="rotateRange" type="range" disabled="disabled" min="-360" max="360" step="1" value="0" />

3. Create a Generate button to render a photo grid after images have been edited.

<button id="createButton" type="button">Create Table</button>

4. Create an empty <img /> to hold the photo grid image.

<button id="createButton" type="button">Create Table</button>

5. Download and insert the JavaScript canvas-table.js after loading the latest jQuery library.

<script src="/path/to/cdn/jquery.min.js"></script>
<script src="/path/to/canvas-table.js"></script>

6. Initialize the plugin on the <canvas /> element and define the paths to the images as follows:

const $canvasTable = $("#canvas").canvasTable({
      // css grid template areas
      templateAreas: ["photo1 photo1 photo1", "photo2 photo3 photo3"],
      images: [
          area: "photo1",
          source: "1.jpg"
          area: "photo2",
          source: "2.jpg"
          area: "photo3",
          source: "3.jpg"
      onSelected(selectedArea) {
        $("#scaleRange").attr("disabled", false);
        $("#rotateRange").attr("disabled", false);

7. Enable the controls & generate button.

$("#scaleRange").on("input", (event) => {

$("#rotateRange").on("input", (event) => {

$("#createButton").click(() => {
  const canvasSource = $canvasTable.createPhoto();
  $("#previewTable").attr("src", canvasSource);

8. Customize the appearance of the canvas table.

const $canvasTable = $("#canvas").canvasTable({
      width: 500,
      height: 500,
      templateAreas: [],
      images: [],
      gap: 1,
      fillStyle: "#fff",
      strokeStyle: "red",
      strokeDash: 0,
      strokeWidth: 3,
      frameImage: "",
      frameWidth: 0,
      showAlignmentLines: true,
      onSelected: () => null

9. API methods:

// scale the image
$canvasTable.changeScale(string | number );

// rotate the image
$canvasTable.changeRotate(string | number );

// generate a photo grid
$canvasTable.createPhoto(type: 'image/png');
