    node-pdf2img-promises

    Build Status

    A Node.js module for converting a pdf into an image file, using Promises.

    This module is based on pdf2img by Fitra Aditya.

    • It was completely refactored to use async/await instead of callbacks
    • Error handling was improved
    • The async lib dependency was removed
    • An option to inform the desired image quality was implemented
    • The lib is now an EventEmitter, so you can listen to the file conversion progress

    Dependencies

    These dependencies must be installed on your server, as the gm package uses them:

    • GraphicsMagick
    • GhostScript

    Installation

      $ npm install pdf2img-promises
    

    Usage

    const fs      = require('fs');
    const path    = require('path');
    const Pdf2Img = require('pdf2img-promises');
     
    let input   = __dirname + '/test.pdf';
    let fileName = 'test';
     
    let converter = new Pdf2Img();
     
    // The event emitter is emitting to the file name
    converter.on(fileName, (msg) => {
        console.log('Received: ', msg);
    });
     
    converter.setOptions({
      type: 'png',                                // png or jpg, default jpg
      size: 1024,                                 // default 1024
      density: 600,                               // default 600
      quality: 100,                               // default 100
      outputdir: __dirname + path.sep + 'output', // output folder, default null (if null given, then it will create folder name same as file name)
      outputname: fileName,                       // output file name, dafault null (if null given, then it will create image name same as input name)
      page: null                                  // convert selected page, default null (if null given, then it will convert all pages)
    });
     
    converter.convert(input)
      .then(info => {
        console.log(info);
      })
      .catch(err => {
        console.error(err);
      })

    It will return array of splitted and converted image files.

    { result: 'success',
      message: 
       [ { page: 1,
           name: 'test_1.jpg',
           size: 17.275,
           path: '/output/test_1.jpg' },
         { page: 2,
           name: 'test_2.jpg',
           size: 24.518,
           path: '/output/test_2.jpg' },
         { page: 3,
           name: 'test_3.jpg',
           size: 24.055,
           path: '/output/test_3.jpg' } ] }
