Installation

Getting started with React Mobile Cropper is straightforward. You can install it using npm or yarn:

npm install --save react-mobile-cropper

Or if you prefer yarn:

yarn add react-mobile-cropper

Basic Usage

Let’s dive into how you can implement React Mobile Cropper in your React application:

import React, { useState } from 'react';
import { CropperRef, Cropper } from 'react-mobile-cropper';
import 'react-mobile-cropper/dist/style.css'

export const ImageCropper = () => {
  const [image, setImage] = useState(
    'https://example.com/path-to-your-image.jpg'
  );

  const onChange = (cropper: CropperRef) => {
    console.log(cropper.getCoordinates(), cropper.getCanvas());
  };

  return (
    <Cropper
      src={image}
      onChange={onChange}
      className={'cropper'}
    />
  );
};

In this example, we’re creating a basic image cropper component. The onChange function is called whenever the crop area is modified, allowing you to access the current coordinates and canvas data.

Advanced Customization

React Mobile Cropper offers extensive customization options to tailor the cropping experience to your needs.

Changing the Stencil Type

You can easily switch between rectangular and circular crop areas:

<Cropper
  src={image}
  onChange={onChange}
  stencilType="circle"
/>

Customizing Colors

To change the main color of the cropper, you can use CSS:

.cropper {
  color: #ff5733;
}

Setting Size Constraints

You can set minimum and maximum dimensions for the crop area:

<Cropper
  src={image}
  onChange={onChange}
  minWidth={200}
  minHeight={200}
  maxWidth={800}
  maxHeight={600}
/>

Custom Stencil Component

For more advanced use cases, you can create and use a custom stencil component:

import { RectangleStencil } from 'react-mobile-cropper';

const CustomStencil = (props) => (
  <RectangleStencil
    {...props}
    aspectRatio={16/9}
    previewClassName="custom-preview"
  />
);

<Cropper
  src={image}
  onChange={onChange}
  stencilComponent={CustomStencil}
/>

Performance Considerations

React Mobile Cropper is designed with performance in mind, using canvas-based rendering for smooth interactions. However, when working with large images or on lower-end devices, you might want to consider using the resizeImage prop to automatically resize large images before cropping:

<Cropper
  src={image}
  onChange={onChange}
  resizeImage={{
    width: 1000,
    height: 1000
  }}
/>

This can significantly improve performance by reducing the size of the image being manipulated.
