react-native-pdf-page-image

This module enables React Native applications to generate images from PDF document pages. It uses PDFKit on iOS and PdfRenderer on Android to render PDF pages as images.

Installation

``sh
npm install react-native-pdf-page-image
`
#### iOS
$ cd ios & pod install

Usage

Importing the Module
`js
import PdfPageImage from 'react-native-pdf-page-image';
`

$3

You can generate images for all pages in a PDF document with the following method:
`js
const uri = "https://pdfobject.com/pdf/sample.pdf";
const scale = 1.0;

// Generate images from all pages
PdfPageImage.generateAllPages(uri, scale)
.then(images => images.forEach((image, index) => console.log(Page ${index+1}: ${image.uri}, Width: ${image.width}, Height: ${image.height})))
.catch(error => console.error('Error generating images:', error));

`

$3

If you only need to generate an image for a single page, use the generate method:
`js
const uri = "https://pdfobject.com/pdf/sample.pdf";
const scale = 1.0;

// Generate an image from a specific page
PdfPageImage.generate(uri, 1, scale) // Example uses page number 1
.then(image => console.log(Generated image: ${image.uri}, Width: ${image.width}, Height: ${image.height}))
.catch(error => console.error('Error generating image:', error));
`

$3

To open a PDF document and retrieve its information, use the open method:
`js
PdfPageImage.open(uri)
.then(info => console.log(PDF opened with URI: ${info.uri}, Page count: ${info.pageCount}))
.catch(error => console.error('Error opening PDF:', error));
`

$3

After processing, you can close the PDF document and delete any temporary files that were generated. Use the close method:
`js
PdfPageImage.close(uri)
.then(() => console.log('PDF closed successfully.'))
.catch(error => console.error('Error closing PDF:', error));
`
