SVG isn't really scalable

[bobspace]

Looking at the SVG output produced by the toString method in my browser, the markup is a bunch of path segments rather than rects, so when you try to actually scale it it turns into a bunch of skinny lines far apart from one another instead of a bigger version of the same QR code.

Rendering in rects would be more verbose, but would be massively more useful and actually scale.

Here's an example output, scaled:

hey i would totally be ok with switching to rects. this was a contribution to begin with and im happy to accept another if you're willing.

That sounds fun! I'll take a crack at it.

Hello
i've a solution for this, at least there are two.

@bobspace At first one question: Where and how do you scale the svg?
e.g. When scaling in Inkscape you should enable the 'Scale Stroke Width' option

Possible solutions:

1. The svg should also accept the scale option, just in the same way as the width option, it will scale up very well.
2. Draw a closed rectangle instead of only lines and use fill instead of stroke for color. And I did not mean the rect tag.

I have both already locally, pull request will follow.

UPDATE:
for 1. see Pull request #247
