Cab be possible add a border to QR Codes ?

Just these, because some times some app for read codes needs a border because the background can have colors that make interferences

thanks !

Why don't you just use CSS to add a border to the QR code?

<img src='images/qrcode.php' style='border: 5px solid COLOR'>

Where COLOR is a color that does not conflict with the current background.

Yes, I use it, but the issue is if you download the code you don't have the border.

If the user is downloading the image, then you lose all control of what background color they will have it set against, and any border set will be as useful as setting no border. You can always change the background color of the image opposed to setting a border, but still the same issue would happen if downloaded.

Just set a large enough padding, maybe?

$qrCode->setPadding(35); // 35px

Can you provide an example screenshot of a image with no border causing "interferences"? I've never come across a QR code that does not scan due to background color differences.

Uffff I don't have any example ! but it's just a suggestion, if it's not possible no problem, the main is that the lib have a option to define a border in the image will can very nice !

Recently the setDrawBorder() method was added that allows you to add a border to the generated code.
