Add margin

[zhengjia]

Hi, this adds a margin to the QR. When background color is dark, position detection pattern is unrecognizable.

Thanks for the contribution :)

Sorry, I may be missing the point here, could this not just be handled in CSS?

.qrcode {margin: 10px;}

@monospaced Yeah it will work on a web page with css. However it may not work as a downloaded image. If I download the QR code and open it in a image viewer, I may not have the ability to control the background color.

To show you an example, the following QR is not scannable.

The source QR code is this .

The default android photo app uses black background color, that's where I find the issue is.
