I\'ve this string from Mysql db:
$img_base64_encoded = \'data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiIHN0YW5kYWxvbmU9Im5vIj8+
For those who generate an HTML variable for output, this is how I got it working: Note that I am generating a barcode using the tc-lib-barcode library found here
$img_base64_encoded = 'data:image/png;base64,' . base64_encode($bobj->getPngData()); $text.= '';
