About

pngenerator : A file preview generator for node.js

Will generate a file preview (gif, jpg or png) of about 450 different document formats.

See pngenerator in action, watch this demo using Angular : https://vimeo.com/151667833

Installation

pngenerator depends on 'unoconv':

  $ apt-get install unoconv

pngenerator depends on 'ffmpeg':

  $ apt-get install ffmpeg

pngenerator depends on 'ImageMagick':

  $ apt-get install imagemagick

pngenerator depends on 'curl':

  $ apt-get install curl

To install use npm:

  $ npm install pngenerator

Usage

Asynchronous with callback (if error, will return error in the callback) :

var pngenerator = require('pngenerator');

pngenerator.generate('/home/myfile.docx', '/home/myfile_preview.gif', function (
  error
) {
  if (error) {
    return console.log(error);
  }
  console.log('File preview is /home/myfile_preview.gif');
});

Synchronous (if error, will return false):

var pngenerator = require('pngenerator');

if (
  !pngenerator.generateSync('/home/myfile.docx', '/home/myfile_preview.gif')
) {
  console.log('Oops, something went wrong.');
} else {
  console.log('File preview is /home/myfile_preview.gif');
}

You can specify a url instead of a file path, ie: http://www.myfile.com/my_file.doc, and pngenerator will download it to generate its preview.

You can set options object for the preview generation. List of options available:

• width
• height
• quality see quality documentation
• background see background documentation
• pagerange [specify pages to export (ie, for pages 1 to 2, pagerange: "1-2", for page 1 to 5, pagerange: "1-5") - for Office documents and PDFs only]

e.g.

var options = {
  width: 640,
  height: 480,
  quality: 90,
  background: '#ffffff',
  pagerange: '1-3'
};

// Asynchronous
pngenerator.generate('/home/myfile.docx', '/home/myfile_preview.gif', options, function(error) {...});

// Synchronous
pngenerator.generateSync('/home/myfile.docx', '/home/myfile_preview.gif', options);

To be more stable, you can run unoconv as listener before running the file preview generation.

$ unoconv --listener
$ node script_with_file_preview_generations.js
