});

CompressImage.createCustomCompressedImage(imageUri, appDirectory, maxWidth, maxHeight, quality).then((response) => {

## Sample App

A basic, sample app is available in [the `example` folder](https://github.com/emekalites/react-native-compress-image/tree/master/example). It uses the module to compress a photo from the Camera Roll.

## API

### `promise createCompressedImage(imageUri, appDirectory)`

The promise resolves with an object containing: `path`, `uri`, `name` and `size` of the new file. The URI can be used directly as the `source` of an [`<Image>`](https://facebook.github.io/react-native/docs/image.html) component.

Option | Description
------ | -----------
imageUri | Path of image file whether jpeg or png
appDirectory | The folder or path to save the compressed image

### `promise createCustomCompressedImage(imageUri, appDirectory, maxWidth, maxHeight, quality)`

The promise resolves with an object containing: `path`, `uri`, `name` and `size` of the new file. The URI can be used directly as the `source` of an [`<Image>`](https://facebook.github.io/react-native/docs/image.html) component.

Option | Description
------ | -----------
imageUri | Path of image file whether jpeg or png
appDirectory | The folder or path to save the compressed image
maxWidth | Image maximum width
maxHeight | Image maximum height
quality | Image quality
