Image editing in rich text editor?

Currently, the built-in rich text editor in Filament does not support direct image editing capabilities such as cropping or adjusting images within the editor itself. To achieve this functionality, you would typically need to integrate a third-party image editing library or find a plugin that can extend the capabilities of the rich text editor.

One popular JavaScript library for image editing is Cropper.js. You can integrate this with the rich text editor to allow users to crop images before inserting them into the editor. Here’s a basic guide on how you might set this up:

Step 1: Install Cropper.js

First, you need to include Cropper.js in your project. You can add it via npm or include it directly from a CDN.

npm install cropperjs

Or include it via CDN:

<link  href="https://cdn.jsdelivr.net/npm/cropperjs/dist/cropper.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/cropperjs/dist/cropper.min.js"></script>

Step 2: Setup HTML for Image Upload

Create an HTML structure for uploading an image and a modal for cropping that image.

<input type="file" id="imageInput" accept="image/*">
<div id="cropperModal" style="display:none;">
    <img id="imageToCrop">
    <button id="cropImage">Crop</button>
</div>

Step 3: Initialize Cropper

Use JavaScript to initialize Cropper when an image is selected.

const imageInput = document.getElementById('imageInput');
const imageToCrop = document.getElementById('imageToCrop');
const cropperModal = document.getElementById('cropperModal');
let cropper;

imageInput.addEventListener('change', function (e) {
    const files = e.target.files;
    if (files.length) {
        const reader = new FileReader();
        reader.onload = function (e) {
            imageToCrop.src = e.target.result;
            cropperModal.style.display = 'block';
            cropper = new Cropper(imageToCrop, {
                aspectRatio: 16 / 9,
                viewMode: 1,
            });
        };
        reader.readAsDataURL(files[0]);
    }
});

document.getElementById('cropImage').addEventListener('click', function () {
    const canvas = cropper.getCroppedCanvas();
    // You can now upload this canvas data to your server or insert it into your rich text editor
    cropperModal.style.display = 'none';
    cropper.destroy();
});

Step 4: Integrate Cropped Image into Rich Text Editor

After cropping, you can convert the canvas to a data URL and insert it into the rich text editor. The exact method will depend on the rich text editor you are using.

This setup provides basic functionality. Depending on your needs, you might want to add more features like resizing, rotating, or advanced cropping options. Also, ensure to handle errors and edge cases (like no file selected, large image files, etc.) for a robust implementation.
