- Output to PNG, GIF, JPEG, or SVG.
- Generates UPC-A, UPC-E, EAN-13, EAN-8, Code 39, Code 93, Code 128, Codabar, ITF, QR Code, and Data Matrix.
Use from a PHP script:
include 'barcode.php';
$generator = new barcode_generator();
/* Output directly to standard output. */
$generator->output_image($format, $symbology, $data, $options);
/* Create bitmap image. */
$image = $generator->render_image($symbology, $data, $options);
imagepng($image);
imagedestroy($image);
/* Generate SVG markup. */
$svg = $generator->render_svg($symbology, $data, $options);
echo $svg;
Use with GET or POST:
barcode.php?f={format}&s={symbology}&d={data}&{options}
e.g.
barcode.php?f=png&s=upc-e&d=06543217
barcode.php?f=svg&s=qr&d=HELLO%20WORLD&sf=8&ms=r&md=0.8
f - Format. One of:
