# react-native-pdf-thumbnail

A react native module for generating thumbnail for PDF files.

A wrapper for:
- PDFKit on iOS (requires iOS 11+)
- PdfRenderer on Android (requires API level 21 - LOLLIPOP)

No other JavaScript or native dependencies needed.

## Installation

```sh
npm install react-native-pdf-thumbnail
```

## Usage

```js
import PdfThumbnail from "react-native-pdf-thumbnail";

// fileUri can use `file` scheme on iOS, `file` and `content` schemes on Android

const { uri, width, height } = await PdfThumbnail.generate(fileUri, 0);

```

The example app contains a document picker, it generates thumbnail for the selected PDF file.
