## Usage

Asynchronous with promises (if error, will return error in the catch block).

```javascript
const fileName = "docs.docx";
const filePath = path.resolve("test","documents", fileName);
const options = {
    width: 300,
    height: 200,
    quality: 100,
    background: '#fff',
    pdf: true,
    keepAspect: true,
    pdf_path: path.resolve("test","pdfs")
}
const outPath = path.resolve ("test", "thumbnail", "test_files", `${fileName.replace(/\.[^/.]+$/, "")}.png`);
filepreview.generateAsync(filePath , outPath, options)
.then( (response) => {
  console.log(response);
  done();
})
.catch( error => done(error));

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

• width
• height
• quality see quality documentation
• background
• pdf
• pdf_path

e.g.

var options = {
  width: 640,
  height: 480,
  quality: 90,
  background: '#fff',
  pdf: true,
  keepAspect: false,
  pdf_path: path.resolve("test","pdfs")
};

// Asynchronous
filepreview.generateAsync(filePath , outPath, options).then( () => done() ).catch( error => done(error));

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
