Laminas Barcode not rendering correctly
I'm attempting to render barcodes for a MVC application in laminas. I can build the barcode object, and the renderer, but when I render it it blacks out the whole screen with a single white square in the middle. I tried replacing my code with the following from PHP Snippets, and I got the same issue. Am I missing a php extension or a composer package or something?
<?php use Common\Util;
use Laminas\Barcode\Object\Code128;
use Laminas\Barcode\Renderer\Image;
$barcode = new Code128([
'text' => 'PHP Snippets',
'barHeight' => 60,
'factor' => 2,
]);
$renderer = new Image([
'resource' => imagecreate($barcode->getWidth(), $barcode->getHeight()),
'barcode' => $barcode,
]);
ob_start();
$renderer->render();
$image = base64_encode(ob_get_contents());
ob_end_clean();
echo '<img src="data:image/png;base64,' . $image . '">';
?>
Here is the html that renders. For some reason it renders the whole <body> as a single image, from the bar code.
<body style="margin: 0px; background: #0e0e0e; height: 100%"><img style="-webkit-user-select: none;margin: auto;background-color: hsl(0, 0%, 90%);transition: background-color 300ms;" src="http://mymvcapp.com/orders"></body>
And here is what displays over the whole browser tab.
