How to use PDF Thumbnail Generator

Import the package at the beginning of your JavaScript file:

Fetch a PDF file from a URL and save it to a local path:

const pdfUrl = 'https://example.com/path-to-pdf.pdf';
const pdfFilePath = 'downloaded-pdf.pdf';

pdfThumbnailGenerator.fetchPDF(pdfUrl, pdfFilePath)
  .then(() => {
    // PDF fetched and saved
  })
  .catch((error) => {
    console.error(error);
  });

Convert the PDF to images and save them in an output directory:

const pdfPath = 'downloaded-pdf.pdf';
const outputDir = 'output-images';

pdfThumbnailGenerator.convertPDFToImages(pdfPath, outputDir)
  .then((result) => {
    // PDF converted to images
  })
  .catch((error) => {
    console.error(error);
  });

Generate a thumbnail from an image and save it to a specified path:

const imagePath = 'output-images/page-1.png';
const thumbnailPath = 'thumbnails/thumbnail.png';
const thumbnailSize = 200;

pdfThumbnailGenerator.generateThumbnail(imagePath, thumbnailPath, thumbnailSize)
  .then(() => {
    // Thumbnail generated and saved
  })
  .catch((error) => {
    console.error(error);
  });
