How to add a webfont to DOMPDF
DOMPDF is a reliable class to convert HTML documents to PDF.
If you haven't already downloaded DOMPDF, you can get it from here:
https://github.com/dompdf/dompdf/releases
These fonts are embedded within the release:
- Courier (Normal, Bold, Oblique, and BoldOblique variants)
- Helvetica (Normal, Bold, Oblique, and BoldOblique variants)
- Times (Normal, Bold, Oblique, and BoldOblique variants)
- Symbol
- ZapfDingbats
and, as of release 0.6.0, DejaVu TrueType fonts are also included.
And now the fun begins!
Lets say that we want to embed the "Roboto" webfont (regular and bold).
Download load_font.php to the same lib directory as dompdf
curl -o load_font.php https://raw.githubusercontent.com/dompdf/utils/master/load_font.php
Open load_font.php with your favorite text editor.
Replace
require_once "autoload.inc.php";
To:
require_once 'dompdf/autoload.inc.php';
Download Roboto font (regular and bold variations) from your favorite source, and place both .ttf under the same lib folder and in subfolder fonts.
lib/fonts/
This is the generic way to run the load_font.php script
php load_font.php new_font_family ./path/to/new_font.ttf
...or in our case:
php load_font.php Roboto ./fonts/Roboto-Regular.ttf ./fonts/Roboto-Bold.ttt
The new webfont is now embedded in DOMPDF!
To use it, specify it in the head tag of your html code:
$page='<html>
<head>
<style>
body{font-family: 'Roboto', sans-serif;}
... rest of css rules here ...
</style>
... your other 'head' tags here ...
</head>
<body>
... HTML CONTENT HERE ...
</body>
</html>
';
/* then use DOMPDF to make the conversion: */
require_once "lib/dompdf/autoload.inc.php";
use Dompdf\Dompdf;
$dompdf = new Dompdf();
$dompdf->loadHtml($page, "UTF-8");
$dompdf->setPaper("A4", "portrait");
$dompdf->set_option('isFontSubsettingEnabled', true);
$dompdf->set_option('defaultMediaType', 'all');
$dompdf->render();
$dompdf->stream(); // stream the pdf in browser
The above commands for DOMPDF are pretty much self explainatory.
