What is react-image-crop?

The react-image-crop package is a React component for cropping images with a user-friendly interface. It allows users to select and crop images within a defined area, providing a variety of customization options for the cropping process.

What are react-image-crop's main functionalities?

Basic Image Cropping

This code demonstrates the basic usage of the react-image-crop package. It allows users to upload an image and then crop it using a resizable and draggable crop area.

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

function ImageCropper() {
  const [crop, setCrop] = useState({ aspect: 16 / 9 });
  const [src, setSrc] = useState(null);

  const onImageLoaded = (image) => {
    // Perform actions when the image is loaded
  };

  const onCropComplete = (crop) => {
    // Perform actions when the crop is complete
  };

  const onCropChange = (crop) => {
    setCrop(crop);
  };

  const handleFileChange = (e) => {
    const file = e.target.files[0];
    const reader = new FileReader();
    reader.onload = () => setSrc(reader.result);
    reader.readAsDataURL(file);
  };

  return (
    <div>
      <input type="file" accept="image/*" onChange={handleFileChange} />
      {src && (
        <ReactCrop
          src={src}
          crop={crop}
          onImageLoaded={onImageLoaded}
          onComplete={onCropComplete}
          onChange={onCropChange}
        />
      )}
    </div>
  );
}

export default ImageCropper;

Aspect Ratio Locking

This code demonstrates how to lock the aspect ratio of the crop area. In this example, the aspect ratio is set to 1:1, meaning the crop area will always be a square.

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

function AspectRatioCropper() {
  const [crop, setCrop] = useState({ aspect: 1 / 1 });
  const [src, setSrc] = useState(null);

  const onImageLoaded = (image) => {
    // Perform actions when the image is loaded
  };

  const onCropComplete = (crop) => {
    // Perform actions when the crop is complete
  };

  const onCropChange = (crop) => {
    setCrop(crop);
  };

  const handleFileChange = (e) => {
    const file = e.target.files[0];
    const reader = new FileReader();
    reader.onload = () => setSrc(reader.result);
    reader.readAsDataURL(file);
  };

  return (
    <div>
      <input type="file" accept="image/*" onChange={handleFileChange} />
      {src && (
        <ReactCrop
          src={src}
          crop={crop}
          onImageLoaded={onImageLoaded}
          onComplete={onCropComplete}
          onChange={onCropChange}
        />
      )}
    </div>
  );
}

export default AspectRatioCropper;

Custom Crop Area Styling

This code demonstrates how to apply custom styling to the crop area. By importing a custom CSS file, you can style the crop area to fit your application's design requirements.

import React, { useState } from 'react';
import ReactCrop from 'react-image-crop';
import 'react-image-crop/dist/ReactCrop.css';
import './CustomCrop.css'; // Custom CSS for crop area

function CustomStyledCropper() {
  const [crop, setCrop] = useState({ aspect: 16 / 9 });
  const [src, setSrc] = useState(null);

  const onImageLoaded = (image) => {
    // Perform actions when the image is loaded
  };

  const onCropComplete = (crop) => {
    // Perform actions when the crop is complete
  };

  const onCropChange = (crop) => {
    setCrop(crop);
  };

  const handleFileChange = (e) => {
    const file = e.target.files[0];
    const reader = new FileReader();
    reader.onload = () => setSrc(reader.result);
    reader.readAsDataURL(file);
  };

  return (
    <div>
      <input type="file" accept="image/*" onChange={handleFileChange} />
      {src && (
        <ReactCrop
          src={src}
          crop={crop}
          onImageLoaded={onImageLoaded}
          onComplete={onCropComplete}
          onChange={onCropChange}
          className="custom-crop"
        />
      )}
    </div>
  );
}

export default CustomStyledCropper;
