Quick Start

Installation

npm install @syncfusion/ej2-image-editor

Security: After installing, run npm audit or verify the package via Socket.dev to confirm the supply-chain integrity of @syncfusion/ej2-image-editor before deploying to production.

Basic Initialization

import { ImageEditor } from '@syncfusion/ej2-image-editor';

// Create a new instance
const imageEditor = new ImageEditor({
    width: '550px',
    height: '330px',
    toolbar: ['Open', 'Save', 'ZoomIn', 'ZoomOut', 'Crop', 'Rotate', 'Flip']
});

// Append to a container
imageEditor.appendTo('#imageeditor');

// Open an image — replace with a validated, trusted URL; never use URLs from third-party responses directly
imageEditor.open('url');

HTML Setup

<div id="imageeditor"></div>

CSS Themes

@import "@syncfusion/ej2-image-editor/styles/material.css";

Common Patterns

Pattern 1: Basic Image Editor with Full Toolbar

import { ImageEditor } from '@syncfusion/ej2-image-editor';

const imageEditor = new ImageEditor({
    width: '600px',
    height: '400px',
    toolbar: ['Open', 'Save', 'ZoomIn', 'ZoomOut', 'Crop', 
              'Rotate', 'Flip', 'Undo', 'Redo', 'Reset'],
    created: () => {
        // Replace 'url' with a validated, trusted image URL or local asset path
        imageEditor.open('url');
    }
});

imageEditor.appendTo('#imageeditor');

Pattern 2: Adding Text Annotation

const dimension = imageEditor.getImageDimension();
imageEditor.drawText(
    dimension.x + 50, 
    dimension.y + 50, 
    'Annotation Text',
    'Arial',      // font family
    30,           // font size
    false,        // bold
    false,        // italic
    'blue',       // text color
    false,        // selected
    null,         // rotation
    '#FFFFCC',    // fill color
    'black'       // stroke color
);

Pattern 3: Applying Filters

import { ImageEditor, ImageFilterOption } from '@syncfusion/ej2-image-editor';

// Apply brightness adjustment
imageEditor.finetuneImage('brightness', 30);

// Apply blur filter
imageEditor.applyImageFilter(ImageFilterOption.Blur);

// Apply multiple fine-tune effects
imageEditor.finetuneImage('contrast', 20);
imageEditor.finetuneImage('saturation', 15);

Pattern 4: Cropping an Image

const dimension = imageEditor.getImageDimension();

// Step 1: Programmatically select a crop region
imageEditor.select('Custom', dimension.x, dimension.y, 500, 300);

// Step 2: Apply the crop
imageEditor.crop();

Pattern 5: Dialog Integration

import { Dialog } from '@syncfusion/ej2-popups';

const dialog = new Dialog({
    width: '600px',
    height: '450px',
    isModal: true,
    visible: false
});
dialog.appendTo('#dialog');

const imageEditor = new ImageEditor({
    width: '100%',
    height: '100%'
});
imageEditor.appendTo('#imageeditor');

document.getElementById('openBtn').onclick = () => {
    dialog.show();
    // Replace 'url' with a validated, trusted image URL
    imageEditor.open('url');
};
