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) :
`
javascript
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):
`
javascript
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.
`
javascript
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
