Understanding react-native-image-crop-picker

If you are looking for a tool to handle image cropping and picking within your React Native application, then react-native-image-crop-picker may be just what you need. This library provides a simple and easy-to-use interface for handling images that are picked from the user's device, and allows for efficient cropping and resizing of those images as needed.

Installation

npm install react-native-image-crop-picker --save

After installing the package, you will need to link it to your project. You can do this using the following command:

react-native link react-native-image-crop-picker

This will automatically link the library to your project.

Usage

Once the library is installed and linked, you can import it into your project using the following code:

import ImagePicker from 'react-native-image-crop-picker';

With this library, you can easily pick images from the user's device using the openPicker or openCamera methods. For example:

ImagePicker.openPicker({
  width: 300,
  height: 400,
  cropping: true
}).then(image => {
  console.log(image);
});

This code will open up a UI that allows the user to select an image from their device. Once the user selects an image, the library will automatically crop and resize the image according to the specified dimensions.

You can also use the openCamera method to capture a new image using the device's camera:

ImagePicker.openCamera({
  width: 300,
  height: 400,
  cropping: true
}).then(image => {
  console.log(image);
});

This code will open up the device's camera and allow the user to capture a new image. Once the user has taken the photo, the library will automatically crop and resize the image according to the specified dimensions.

In addition to these basic features, react-native-image-crop-picker also provides a variety of advanced options for handling images, including:

• Specifying the MIME type of the image
• Setting a custom compression level for the resulting image
• Specifying a custom filename for the resulting image
• And more!

Overall, react-native-image-crop-picker is a powerful and flexible library that can help you handle images within your React Native application with ease.
