Want to find the way to generate the thumbnail image for a given pdf file

I'm currently looking for a way to generate the thumbnail image for a given pdf file, which shows several pages in the same image. The output should like what shows in the arxiv sanity website. I want to know if there is any npm package which supports this functionality. Thanks.

In ImageMagick command line, you can do that as follows. Suppose you want 8 pages from the PDF.

Input PDF from http://www.arxiv-sanity.com:

convert image.pdf[0-7] -thumbnail 140x140 -background white +smush 20 -bordercolor white -border 10 result.jpg


enter image description here

This takes the first 8 pages, makes thumbnails of size 140x140 and appends them side-by-side with a 20 pixels white spacing between them and adds a 10 pixel white border around it all.

Sorry, I do not know Node.js. But apparently there is a module that integrates ImageMagick. See https://github.com/yourdeveloper/node-imagemagick

var PDFImage = require("pdf-image").PDFImage; //pdf to image convert

var pdfImage = new PDFImage("1120.pdf");
  pdfImage.convertPage(0).then(function (imagePath) {
},(err)=>{
   console.log("err",err)
})

//##jimp Npm use thumbnail image generate

//if auth error Follow this step : -> In /etc/ImageMagick-6/policy.xml (or /etc/ImageMagick/policy.xml) find the following line -> and change it to allow reading and writing by the PDF coder in ImageMagick:
