```

## Code example
```javascript
var fs = require('fs');

var html = fs.readFileSync('./test/businesscard.html', 'utf8');
var options = { format: 'Letter' };

pdf.create(html, options).toFile('./businesscard.pdf', function(err, res) {
  if (err) return console.log(err);
  console.log(res); // { filename: '/app/businesscard.pdf' }
});
```

## API

```js
var pdf = require('html-pdf');
pdf.create(html).toFile([filepath, ]function(err, res){
  console.log(res.filename);
});

pdf.create(html).toStream(function(err, stream){
  stream.pipe(fs.createWriteStream('./foo.pdf'));
});

pdf.create(html).toBuffer(function(err, buffer){
  console.log('This is a buffer:', Buffer.isBuffer(buffer));
});


// for backwards compatibility
// alias to pdf.create(html[, options]).toBuffer(callback)
pdf.create(html [, options], function(err, buffer){});
```

### Footers and Headers

`html-pdf` can read the header or footer either out of the `footer` and `header` config object or out of the html source. You can either set a default header & footer or overwrite that by appending a page number (1 based index) to the `id="pageHeader"` attribute of a html tag.

You can use any combination of those tags. The library tries to find any element, that contains the `pageHeader` or `pageFooter` id prefix.
```html
<div id="pageHeader">Default header</div>
<div id="pageHeader-first">Header on first page</div>
<div id="pageHeader-2">Header on second page</div>
<div id="pageHeader-3">Header on third page</div>
<div id="pageHeader-last">Header on last page</div>
...
<div id="pageFooter">Default footer</div>
<div id="pageFooter-first">Footer on first page</div>
<div id="pageFooter-2">Footer on second page</div>
<div id="pageFooter-last">Footer on last page</div>
```

There are more options concerning the paperSize, header & footer options inside the phantomjs script.
