ImageMagick 7.0.4 / NodeJS 6.9.2 / GPLGS 9.15 / Win 7: Failing to convert files

Question

Problem

I am able to do a conversion from PDF to another image format from the command-line using the convert.exe ImageMagick command. However, when running the following JS in Node I get the error that follows the code below.

JavaScript

fs = require('fs');

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

console.log("Start");

var pdfImage = new PDFImage('test.pdf');
pdfImage.convertPage(0).then(function (imagePath) {
  // 0-th page (first page) of the slide.pdf is available as slide-0.png 
  console.log('Converted');
  fs.existsSync('test-0.png') // => true 
}, function (err) {
    console.log(err);
});

package.json

{
  "name": "pdftester",
  "version": "1.0.0",
  "description": "PDF Tester",
  "main": "PDFTester.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "John Doe",
  "license": "ISC",
  "dependencies": {
    "async": "^2.1.4",
    "imagemagick": "^0.1.3",
    "pdf-image": "^1.1.0",
    "pdftotextjs": "^0.4.0"
  }
}

Analysis

The offending line is the command-line built for convert.exe, that is:

'convert \'test.pdf[0]\' \'test-0.png\''

What is adding the extra slashes, ticks ('), and '[0]'?

Thanks in advance!

Answer 1

according to your question , extra slashes denotes to enter in folder. you have to put your file with respect to server file from where it starts. or put your pdf file into from where your running your apps.
