Open-Source Design Editor SDKs: A Developer's Guide to Choosing the Right Solution

Klaudia — Tue, 25 Nov 2025 08:56:18 GMT

If you’re implementing design or editing capabilities, you’ve probably wondered whether to use an open-source library or go with a commercial SDK. It’s a fair question—especially when there are established libraries like Fabric.js and Konva.js that offer powerful canvas manipulation tools without licensing costs.

Here’s the reality: there’s no single open-source SDK that delivers a complete, production-ready design editor out of the box. Instead, developers typically piece together solutions from canvas libraries, rendering engines, and SVG tools—each requiring custom UI development, editor logic, and ongoing maintenance.

In this guide, we’ll walk through the most popular open-source options for building design editors, organized by what they actually do: canvas manipulation, high-performance rendering, or SVG control. We’ll cover what each library excels at, where you’ll hit roadblocks, and how much development effort you’re really signing up for. Then we’ll show how IMG.LY CE.SDK approaches the same challenges with a different philosophy: providing a complete, enterprise-ready editor that works across platforms from day one.

The Open-Source Landscape: What You’re Actually Choosing

When you choose an open-source approach to building a design editor, you’re typically selecting from three categories of tools. Each solves part of the puzzle, but none deliver a complete editor experience without significant custom development.

1. Canvas and Drawing Libraries

These libraries handle core canvas drawing and object manipulation—layers, transformations, text, images—but they don’t include prebuilt editor UI or workflows. Think of them as powerful toolkits that give you the building blocks, but you’re responsible for assembling the actual editor experience.

2. Rendering Engines

Optimized for high-performance graphics and WebGL-powered rendering, these engines excel at drawing complex scenes quickly. However, they’re focused purely on rendering—no editing workflows, no UI components, no editor logic. Great for graphics-heavy applications, but you’ll need to build everything else yourself.

3. SVG Manipulation Libraries

Lightweight tools for creating, transforming, and animating SVG elements with precision. Perfect for SVG-based graphics projects, but like the others, they require you to build the editor UI and interaction logic from scratch.

Let’s dive into each category and see what these tools actually offer.

Canvas and Drawing Libraries: Flexible Foundations Without the Editor UI

Canvas libraries provide rich object manipulation capabilities—layers, transformations, events, custom controls—but they stop short of delivering ready-made editor interfaces. You get the power and flexibility to build exactly what you want, but you’re taking on the responsibility of creating polished, user-friendly editing experiences.

Fabric.js

Fabric.js is one of the most popular HTML5 canvas libraries for interactive object editing. It’s been around for years and has a large community, extensive documentation, and plenty of examples showing how to manipulate canvas objects programmatically.

Fabric.js gives you layers, object manipulation (resize, rotate, drag), text rendering, image handling, custom controls, and event systems. It’s feature-rich and handles most of what you’d need at the object level for a design editor.

Platforms:
Web only—Fabric.js runs on the HTML5 Canvas API, so it’s browser-based.

Difficulty Building a Full Editor:
Medium. Fabric.js provides the canvas toolkit, but building a polished, production-ready editor means developing the entire UI layer: toolbars, property panels, layer management, undo/redo, export controls, and more. You’ll also need to handle performance optimizations for complex designs and manage state across the editor experience.

Potential Roadblocks:
No ready-made editor UI means substantial frontend development work. Scaling can become an issue with very large or complex designs—you’ll need to implement custom optimizations. Managing collaborative editing, version control, or template systems requires building those features from scratch.

Use Cases:
Product customizers (t-shirts, mugs, promotional items), custom design tools for SaaS platforms, marketing asset creators, and interactive whiteboards.

Future-Proofing:
Fabric.js is mature, stable, and actively maintained by its community. It’s a safe bet for long-term projects, though you’re responsible for keeping up with web standards and browser changes.

Support:

Key Challenges:
Extremely high custom development overhead to implement editing features, object manipulation, and user interfaces. Steep learning curves for WebGL optimization and rendering pipelines. Limited community support for editor-specific use cases.

SVG Manipulation: Lightweight Control, Custom UI Required

SVG libraries give you precise control over vector graphics—shapes, transformations, animations, filters—without the overhead of canvas rendering. They’re lightweight, performant for moderate-scale graphics, and ideal for projects where SVG’s scalability and precision matter. But like canvas libraries, they provide no editor UI or workflows—you’re building those yourself.

SVG.js

SVG.js is a lightweight library for creating, manipulating, and animating SVG elements. It’s simple, fast, and focused exclusively on SVG—no canvas, no WebGL, just vector graphics.

Features & Capabilities:
SVG shape creation (rectangles, circles, paths, polygons), transformations (rotate, scale, translate), event handling, filters and effects, animations, and group management. SVG.js gives you direct, low-level control over SVG elements.

Platforms:

Open-Source Photo Editing SDKs vs IMG.LY CE.SDK: An Honest Comparison for Developers

Klaudia — Tue, 25 Nov 2025 07:48:22 GMT

If you’re building an app that needs photo editing capabilities, you’ve probably asked yourself: should I use an open-source library or go with a commercial SDK?

Open-source tools offer flexibility and zero licensing costs, which makes them attractive when you’re starting out. But they also come with trade-offs. You’ll need to handle UI development, performance optimization, and ongoing maintenance yourself. And as your app scales, those “free” solutions can become surprisingly expensive in engineering time.

In this article, we’ll compare the most popular open-source photo editing SDKs and libraries like Jimp, Pica, OpenCV, ImageMagick, and GraphicsMagick and show you how they stack up against IMG.LY CE.SDK, our enterprise-grade editing solution. We’ll be honest about where open-source tools shine (flexibility, cost) and where commercial SDKs like ours stand out (UI, scalability, automation, and enterprise support).

We’ll also dig into what it actually takes to build with each option: difficulty of integration, potential roadblocks you’ll hit, and what happens when you need to scale beyond a prototype.

1. Jimp

Jimp is a pure JavaScript image processing library built for Node.js and browser environments. It’s one of the most popular open-source options for developers who need basic image manipulation without native dependencies.

Features & Capabilities

Key features:

Resize, crop, rotate images
Apply filters (blur, grayscale, sepia, brightness, contrast)
Color adjustments and overlays
Text rendering on images
Format conversions (JPEG, PNG, BMP, TIFF, GIF)
Simple compositing and blending

Platforms

Node.js
Browser (with bundlers like Webpack or Rollup)

Difficulty Building

Low. Jimp is easy to get started with. You install it via npm, import it, and start processing images with a simple API. There’s minimal setup and no need to configure native dependencies, which makes it beginner-friendly.

Potential Roadblocks

Performance issues with large images. Because Jimp runs entirely in JavaScript, it’s not optimized for heavy workloads or high-resolution images. If you’re processing thousands of images or working with files larger than a few megabytes, you’ll notice slowdowns.

No built-in UI. Jimp is a processing library, not an editor. If you want users to interact with images (adjust brightness, apply filters visually), you’ll need to build the entire interface yourself.

Limited advanced features. Jimp doesn’t support layer-based editing, masking, or advanced compositing. It’s great for quick transformations but won’t help you build a Photoshop-like experience.

Use Cases

Small to medium web apps needing server-side image manipulation
Quick prototyping of image features
Backend workflows for resizing user uploads
Simple filters and adjustments in Node.js environments

Support & Pricing

Jimp is actively maintained on GitHub with a strong community. It’s completely free and open-source (MIT license), which means no licensing costs but also no dedicated support team.

Who It’s For

Developers who need a lightweight, Node-friendly image library for basic transformations and don’t want to deal with native dependencies.

Comparison to IMG.LY CE.SDK

Jimp is simple and flexible for basic image processing, but it’s not built for end-user editing experiences. IMG.LY CE.SDK offers a production-ready photo editor with a polished UI, advanced editing features (layers, masks, filters, AI enhancements), and cross-platform support (Web, iOS, Android, React Native, Flutter). Where Jimp requires you to build everything from scratch, our SDK gives you a complete editing solution that integrates in hours, not months.

2. Pica

Pica is a high-quality image resizing library focused on performance and accuracy. It’s designed to do one thing extremely well: resize images using advanced algorithms like Lanczos3, which preserve image quality better than standard browser or canvas resizing.

Features & Capabilities

Compositing and layering
Batch processing for thousands of images
PDF and SVG support
Scriptable automation

Platforms

Cross-platform: Linux, Windows, macOS
Language bindings: Node.js, PHP, Python, Ruby, Perl, and more

Difficulty Building

Medium. The command-line syntax is powerful but syntax-heavy. You’ll spend time learning the specific flags and options for each operation. Language bindings simplify integration, but you still need to understand the underlying CLI logic.

Potential Roadblocks

Steep learning curve. The CLI syntax is powerful but not intuitive. Documentation can feel overwhelming because of the sheer number of options available.

No UI. These are backend processing tools. If you want users to edit images interactively, you’ll need to build the entire frontend yourself.

Security concerns. ImageMagick has had several security vulnerabilities over the years (like ImageTragick). You’ll need to stay on top of updates and security patches.

Conclusion: Which Photo Editing SDK Is Right for You?

Here’s the honest breakdown:

Jimp is great for quick, lightweight Node.js image manipulation: resizing uploads, applying basic filters, or prototyping. But it’s limited for large-scale workloads or advanced editing features. If you’re building a simple backend image pipeline, Jimp works. If you need a user-facing editor, you’ll hit roadblocks fast.

Pica excels at high-quality resizing and does it better than almost anything else. But it’s a single-purpose tool. You’ll need other libraries for cropping, filtering, and everything else that makes up a complete editing experience.

OpenCV is extremely powerful for computer vision and image analysis — facial recognition, object detection, advanced transformations. But it’s complex, requires a steep learning curve, and doesn’t include a UI. If you’re building AI-powered vision features, OpenCV is the industry standard. If you’re building a photo editor for users, it’s overkill (and you’ll still need to build everything else yourself).

ImageMagick and GraphicsMagick are ideal for server-side automation and batch processing. They’re reliable, scalable, and handle format conversions beautifully. But they’re backend tools - no UI, steep CLI syntax, and security concerns you’ll need to manage. Great for automating image workflows behind the scenes; not suited for interactive editing.

IMG.LY CE.SDK is the only solution that combines cross-platform editing, enterprise-grade scalability, polished UI, templates, AI features, and automation in one package. Where open-source tools require you to piece together multiple libraries (and build the UI yourself), our SDK gives you a complete, production-ready editing solution that integrates in hours.

If you’re evaluating open-source tools, ask yourself:

Do I need a user-facing editor or just backend processing?
How much engineering time will I spend building and maintaining a custom solution?
What happens when I need to scale or add new features?

Open-source libraries are excellent for narrow use cases, but they require significant development investment. CE.SDK eliminates that overhead so your team can focus on what makes your product unique — not rebuilding image editing from scratch.

Build vs. Buy: Is Fabric.js Right for You

Jan — Thu, 15 May 2025 09:31:43 GMT

When you’re building a design editor into your product whether for social content, marketing assets, video, or design workflows choosing the right foundation matters. Many teams start with Fabric.js, an open-source canvas library, attracted by its flexibility and permissive license. But as the project scope grows, so do the limitations.

This article explores the advantages, but also the pitfalls of building a creative tool with Fabric.js and why many product teams ultimately decide to switch or start with a commercial SDK like IMG.LY’s CreativeEditor SDK (CE.SDK).

Consult our comparison page of Fabric.js and IMG.LY for a feature by feature breakdown of the differences between our SDKs and Fabric.js.

Why Teams Switch from Fabric.js

We’ve spoken with dozens of companies, from startups to enterprise clients, who evaluated Fabric.js and in many cases opted for IMG.LY instead. Here’s what we consistently hear:

1. Time-to-Market vs. Reinventing the Wheel

Open-source is attractive at first. But once the excitement of building wears off, teams often face a sobering reality: stitching together a decent editing experience from Fabric.js is a months-long effort.

“We used Fabric.js before, but if IMG.LY’s SDK is cost-effective, we’d rather not reinvent the wheel.”

— B2B SaaS Prospect

They want a modern editor UI, fast iteration cycles, and a stable base not to spend their next quarter building the basics like zoom, text editing, object grouping, layer management, or responsive templates.

2. Lack of Advanced Features

Fabric.js excels at low-level canvas manipulation, offering a robust API for working directly with objects on the HTML5 canvas - shapes, images, text, and transformations. It’s a great starting point for developers who want fine-grained control over rendering and interactivity. However, it falls short when it comes to modern editing paradigms. Fabric.js provides no native concept of reusable templates, lacks support for layout and design constraints like alignment guides or snapping behavior, and does not include higher-level abstractions for content-aware or AI-powered editing. In short, Fabric.js gives you a raw toolkit, not a polished, plug-and-play editing solution. If you’re building a sophisticated design application, you’ll need to layer these capabilities yourself or integrate additional frameworks to bridge the gap.

“We needed a template system and advanced photo editing. Open-source libraries couldn’t do it out of the box.”

— Marketplace Platform Prospect

Teams chasing parity with Canva or Adobe tools quickly hit walls. What starts as a proof-of-concept becomes a rebuild of the tables stakes of design editing.

Real-World Use Cases & Vertical-Specific Challenges

We’ve seen teams from various industries reach the same conclusion: Fabric.js doesn’t scale to meet their creative, technical, or business needs. A few common themes:

E-commerce & Web-to-Print: Retailers building product customization flows need template constraints, consistent output quality, and export formats that go beyond canvas. They can’t afford rendering inconsistencies or unpredictable export fidelity.
MarTech & Social Media Tools: Marketers need batch generation, AI-assisted creative workflow, brand constraints and consistent creative output across devices. Fabric.js lacks built-in support for these workflows.
Mobile-first Apps: Teams building hybrid apps or web apps that need to be functional on mobile struggle with Fabric.js’ lacklustre mobile support. The inability to deliver a consistent UX across iOS, Android, and Web leads to dropped features or split tech stacks.
Video and Multimedia Platforms: Fabric.js has no native video support, track-based editing, or multi-frame logic. Prospects in this space frequently abandon their Fabric.js POCs once real constraints emerge.

A major pain point across all verticals is rendering consistency. CE.SDK renders identically across browser, server, and mobile thanks to a shared rendering core (CreativeEngine). This is critical for:

Workflows that begin on web and finish on mobile
Server-side generation (e.g., previews, PDFs, batch exports)
Feature parity and UX reliability across platforms

Check out our demo page to explore these use cases.

Technical Debt: The Hidden Cost of Fabric.js

On paper, Fabric.js seems like a fast way to get started. But its real cost emerges over time in performance bottlenecks, missing architecture, and maintenance drag.

Aging Codebase and Patchy Maintenance

As of 2025, Fabric.js has over 400 open issues on GitHub, some dating back years. Many feature requests such as better performance for large object sets, async rendering, or text-on-path improvements are either unresolved or uncertainly prioritized.

The core maintainers do their best, but progress is slow. You’re relying on volunteer effort for critical infrastructure.

Slow Issue Resolution

Many of the GitHub issues (e.g., #5885, #6582) highlight long-standing rendering bugs and performance problems. These are hard to fix, and updates can break your own hacks or workarounds.

Unlike a commercial SDK, Fabric.js doesn’t guarantee backward compatibility. No SLAs. Little roadmap visibility.

Customer Feedback: Why They Walked Away

Here are some soundbites from our customers and prospects on why they decided against building with Fabric.js:

“The quality and UX didn’t meet our standards.”
Product Customizer

“Developer experience was poor. We spent more time debugging than building features.”
B2B SaaS Ad Design

“We needed enterprise support, scalability, and documentation. Open source didn’t cut it.”
Web to print Customer

“Cross-platform support and minimum SDK version constraints were a major blocker.”
Claim Management Application

Voice of the Dev

Beyond enterprise evaluations, developers working with Fabric.js often share their struggles publicly on GitHub, Stack Overflow, and developer forums. Their commentary offers real-world insight into day-to-day frustrations:

“FabricJS doesn’t seem to work well on Mobile.”

Github issue #6980

“Fabric.js object controls don’t work until after a common selection is made. Had to hack around it with extra event listeners.”

StackOverflow

“Trying to integrate Fabric.js with Next.js + Rollup is a mess. Unexpected tokens, config rewrites — it doesn’t play well with modern bundlers.”

GitHub Issue #8444

“We’re blocked by the use of ‘unsafe-eval’ due to our content security policy. Fabric.js needs a rewrite to be CSP-compliant.”

GitHub Issue #9666

Concrete takeaways from developer feedback:

Basic UI control quirks: Common issues with selection handling and control behavior require manual workarounds.
Compatibility friction: Fabric.js does not play well with modern build tools like Next.js and Rollup without additional configuration or patching.
Security blockers: The reliance on unsafe-eval creates CSP conflicts, making it unsuitable for projects with strict security requirements.
Uncertain roadmap: Critical features like async rendering may sit open for years, and niche features important to your use case may never land if they don’t align with community priorities.

While every open source project faces these difficulties, they do represent systemic issues with performance, extensibility, and production-readiness. For teams building long-lived, customer-facing tools, this developer feedback is often a leading indicator of future roadblocks.

Back-of-the-Envelope Cost of Building with Fabric.js

Many teams underestimate the cost of building a design editor from scratch. Here’s a rough breakdown of the time investment we’ve heard from teams who tried:

Task	Estimated Engineering Time
Core canvas-based editor UI (zoom, drag, resize, selection, tool switching)	6–8 weeks
SVG support, snapping, grouping, and layer management	4–6 weeks
Template constraints	3–5 weeks
Cross-platform adaptation (ironing out issues on mobile browsers, defining fallbacks)	4–6 weeks
Bug triage, ongoing maintenance, and refactors (first 12–18 months)	6–9 weeks

Total: ~6–8 months of senior dev time just to get to feature parity with what CE.SDK offers out of the box.

This doesn’t include the cost of QA, product management, or future extensibility. Nor the opportunity cost of what your team could be building instead.

When Does Fabric.js Still Make Sense?

This article might read like a put-down, but it’s not supposed to be that. Until now we were simply evaluating Fabric.js with respect to building fully-featured design editing tools. There are, however, a number of well-scoped use cases where Fabric.js excels. These include:

Building an internal tool, proof of concept, or educational app
Creating a custom, single-platform sketching or annotation layer
Developing a low-fidelity prototype with full code-level control
Building canvas collaboration tools such as drag and drop editors or interactive canvases, such as Miro.

An example of where Fabric.js worked well is a tool such as Mockola, a drag-and-drop diagram editor, where shape manipulation, lightweight rendering, and canvas-level control are more important than cross-platform design fidelity. Mockola’s is a good use case, because its emphasis on real-time collaboration and planning rather than high-fidelity design. This means that features like free drawing, drag-and-drop, and JSON-based serialization are a great fit, all of which Fabric.js supports out of the box.

For teams willing to invest in building and maintaining their own editor infrastructure and whose use case does not require cross-platform parity, advanced media editing, or enterprise scaling Fabric.js continues to be a compelling foundation.

However, for products that need to ship quickly, scale reliably, and support modern creative workflows across platforms, IMG.LY’s CE.SDK offers the infrastructure and polish that customers now expect.

The Bottom Line

As MIT CIO Symposium speaker Mark Holst-Knudsen put it:

“You shouldn’t build anything that’s available off the shelf because it’s not a source of competitive advantage if everybody else can avail themselves of it.”

For most companies, building an editor from scratch is not a competitive edge, it’s a distraction from shipping and scaling. And Fabric.js, while capable in the hands of specialists, isn’t a shortcut to the finish line.

IMG.LY’s CE.SDK gives you a head start with advanced editing features, AI automation, template support, plugin extensibility, rendering consistency, and battle-tested scalability across platforms. We put together a data report based on 600+ customers, 28 structured customer interviews, and a self-reported customer survey that speaks for itself when it comes to real-life outcomes.

So before you dive into Fabric.js and start reinventing core functionality, ask yourself: What competitive advantage are you going to build on top of a design editor and which functionality are you better served buying from a trusted vendor?

How To Crop an Image in React

Antonello — Mon, 28 Jun 2021 17:03:00 GMT

In this article, you will learn to crop an image in JavaScript. Specifically, you will see how to achieve this goal with the react-image-crop React library.

Over the last few years, providing users with features to deal with images has become more and more common. This is why every developer should know how to deal with basic operations on images, such as cropping. This gives them the possibility to choose only the areas they are interested in.

So, let’s see how to crop an image in React with react-image-crop. Follow this step-by-step tutorial to achieve the following result:

Prerequisites

This is the list of all the prerequisites for the demo application you are going to build:

Node.js and npm 5.2+ and higher
react-image-crop >= 8.6.12

Cropping an Image with `react-image-crop`

You can clone the GitHub repository that supports this article and try the demo application by launching the following commands:

git clone https://github.com/imgly/Blog-How-To-Crop-an-Image-in-React-with-React-Crop-Image.git
cd Blog-How-To-Crop-an-Image-in-React-with-React-Crop-Image
npm i
npm start

Otherwise, you can continue following this tutorial and build the demo application step by step.

1. Creating a React Project

The easiest way to create an empty working project in React is by using Create React App, the officially supported way to create single-page React applications. You can create a new project called react-image-cropper-demo with the following command:

npx create-react-app react-image-cropper-demo

You will now have a demo project located in the react-image-cropper-demo folder with this file structure:

react-image-cropper-demo
├── README.md
├── node_modules
├── package.json
├── .gitignore
├── public
│   ├── favicon.ico
│   ├── index.html
│   ├── logo192.png
│   ├── logo512.png
│   ├── manifest.json
│   └── robots.txt
└── src
    ├── App.css
    ├── App.js
    ├── App.test.js
    ├── index.css
    ├── index.js
    ├── logo.svg
    ├── reportWebVitals.js
    └── setupTests.js

Move into the react-image-cropper-demo folder and launch a local server by running:

cd react-image-cropper-demo
npm start

Visit http://localhost:3000/ in your browser, and you should be able to see the default Create React App screen.

2. Installing `react-image-crop`

Add the react-image-crop library to your project’s dependencies by running the following command:

npm install --save react-image-crop

Your package.json file will be updated accordingly, and you should now be able to see react-image-crop as a dependency.
Now, you have everything required to start developing your image cropper component.

3. Building the Image Cropper Component

First of all, create a components folder inside src. Then, make an ImageCropper folder containing index.js and index.css. These two files will contain the cropper component definition and style respectively.

Initialize index.js with the following lines of code:

import React from 'react';

function ImageCropper() {
  return <div>{/*TODO*/}</div>;
}

export default ImageCropper;

This way, you have just created an empty ImageCropper component.
Now, you need to import ReactCrop, which is part of the react-image-crop library. Add it to the ImageCropper imports:

import ReactCrop from 'react-image-crop';

Plus, do not forget to import dist/ReactCrop.css or ReactCrop.scss as follows:

import 'react-image-crop/dist/ReactCrop.css';
// or scss:
import 'react-image-crop/lib/ReactCrop.scss';

This is what the final ImageCropper will look like:

import React, { useState } from 'react';
import ReactCrop from 'react-image-crop';
import 'react-image-crop/dist/ReactCrop.css';
import demoImage from './demo-image.jpg';

function ImageCropper(props) {
  const { imageToCrop, onImageCropped } = props;

  const [cropConfig, setCropConfig] = useState(
    // default crop config
    {
      unit: '%',
      width: 30,
      aspect: 16 / 9,
    }
  );

  const [imageRef, setImageRef] = useState();

  async function cropImage(crop) {
    if (imageRef && crop.width && crop.height) {
      const croppedImage = await getCroppedImage(
        imageRef,
        crop,
        'croppedImage.jpeg' // destination filename
      );

      // calling the props function to expose
      // croppedImage to the parent component
      onImageCropped(croppedImage);
    }
  }

  function getCroppedImage(sourceImage, cropConfig, fileName) {
    // creating the cropped image from the source image
    const canvas = document.createElement('canvas');
    const scaleX = sourceImage.naturalWidth / sourceImage.width;
    const scaleY = sourceImage.naturalHeight / sourceImage.height;
    canvas.width = cropConfig.width;
    canvas.height = cropConfig.height;
    const ctx = canvas.getContext('2d');

    ctx.drawImage(
      sourceImage,
      cropConfig.x * scaleX,
      cropConfig.y * scaleY,
      cropConfig.width * scaleX,
      cropConfig.height * scaleY,
      0,
      0,
      cropConfig.width,
      cropConfig.height
    );

    return new Promise((resolve, reject) => {
      canvas.toBlob((blob) => {
        // returning an error
        if (!blob) {
          reject(new Error('Canvas is empty'));
          return;
        }

        blob.name = fileName;
        // creating a Object URL representing the Blob object given
        const croppedImageUrl = window.URL.createObjectURL(blob);

        resolve(croppedImageUrl);
      }, 'image/jpeg');
    });
  }

  return (
    <ReactCrop
      src={imageToCrop || demoImage}
      crop={cropConfig}
      ruleOfThirds
      onImageLoaded={(imageRef) => setImageRef(imageRef)}
      onComplete={(cropConfig) => cropImage(cropConfig)}
      onChange={(cropConfig) => setCropConfig(cropConfig)}
      crossorigin="anonymous" // to avoid CORS-related problems
    />
  );
}

ImageCropper.defaultProps = {
  onImageCropped: () => {},
};

export default ImageCropper;

imageToCrop is the source image received from the props. The or statement used when assigning the ReactCrop’s src props assures that either imageToCrop or a default demo image is shown. After being loaded, a reference to the image is saved and then used when performing the cropping operation. Then, whenever a user uses the component to try to crop an image, the cropConfig object containing the crop settings is updated accordingly. Finally, when the user stops selecting the area to crop, cropImage is called. This function is in charge of producing the cropped image and passing it to the onImageCropped function received from the props.

4. Putting It All Together

Now it is time to see the ImageCropper component in action. All you need to do, is change the App.js file as follows:

import React, { useState } from 'react';
import './App.css';
import ImageCropper from './components/ImageCropper';

function App() {
  const [imageToCrop, setImageToCrop] = useState(undefined);
  const [croppedImage, setCroppedImage] = useState(undefined);

  const onUploadFile = (event) => {
    if (event.target.files && event.target.files.length > 0) {
      const reader = new FileReader();

      reader.addEventListener('load', () => setImageToCrop(reader.result));

      reader.readAsDataURL(event.target.files[0]);
    }
  };

  return (
    <div className="app">
      <input type="file" accept="image/*" onChange={onUploadFile} />
      <div>
        <ImageCropper
          imageToCrop={imageToCrop}
          onImageCropped={(croppedImage) => setCroppedImage(croppedImage)}
        />
      </div>
      {croppedImage && (
        <div>
          <h2>Cropped Image</h2>
          <img alt="Cropped Image" src={croppedImage} />
        </div>
      )}
    </div>
  );
}

export default App;

The input element allows users to upload an image, then stored it in imageToCrop and passed to ImageCropper. Each time a user crops it, the resulting image is saved thanks to the setCroppedImage function. Then, it is finally displayed in the Cropped Image section as presented in the fiddle at the beginning of the article.

Final Considerations on `react-image-crop`

Cropping an image from scratch is not an easy task. This is why using a library like react-image-crop is the recommended approach. As you have just seen, you can achieve your goal with just a few lines of code. This is great! On the other hand, these libraries are designed to achieve specific goals, like cropping an image. What if you need to perform or get users the possibility to do other image-related operations? You may be ending up with as many libraries as operations required.

Not only might they have very different UIs, but it may also be complicated to integrate them all in the same project. This is why in such a circumstance, a commercial and wider solution like PhotoEditorSDK should be the preferred approach. In fact, with only one library you get several tools to treat images as you want, while preserving the consistency of your application’s UI. Also, whenever you need help, you can ask for support from the img.ly developers who built the SDK or visit one of the myriad snappy integration guides written by the developers on the blog.

Cropping an Image with PhotoEditorSDK

First, you should read this article from the official documentation on how to get started with PhotoEditorSDK in React. Then, by using the transform tool you can perform cropping, resizing, flipping, and rotation operations with just one feature. This way, you should be able to achieve the desired result:

Conclusion

In this article, we looked at how to crop an image in React. Cropping an image can turn into a complex task and this is using a library should be the preferred approach. In particular, react-image-crop allows you to crop an image easily and with only a handful of lines of code, as we have seen. On the other hand, it is a library with a very specific purpose. So, if you needed to perform more than one operation on your images, you might need a more advanced and complete solution like PhotoEditorSDK.
