I want to generate barcodes in my application. When I run the code locally
php bin/console server:run 0.0.0.0
on my Windows PC, it works like a charm, but when I push it to my Git repository and pull it on my Apache2 Server an test it there, I get black bars.
The composer.json files are the same and the PHP Version also (PHP 7.4.7)
I am working with Symfony 4 and picqer/php-barcode-generator (https://github.com/picqer/php-barcode-generator).
In the controller:
$barcodeList[$barcode->getId()]['img'] = base64_encode($generator->getBarcode(intval($barcode->getValue()), $generator::TYPE_EAN_13, 1, 25));
In the template:
<img src="data:image/png;base64,{{ barcode.img }}" >
Example of the result on my local PC:
