Installation

  $ [sudo] npm install pdf2img

Usage

var fs      = require('fs');
var path    = require('path');
var pdf2img = require('pdf2img');

var input   = __dirname + '/test.pdf';

pdf2img.setOptions({
  type: 'png',                                // png or jpg, default jpg
  size: 1024,                                 // default 1024
  density: 600,                               // default 600
  outputdir: __dirname + path.sep + 'output', // output folder, default null (if null given, then it will create folder name same as file name)
  outputname: 'test',                         // 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)
  quality: 100                                // jpg compression quality, default: 100
});

pdf2img.convert(input, function(err, info) {
  if (err) console.log(err)
  else console.log(info);
});

It will return array of splitted and converted image files.
