Add logo #90

Does anyone know if it's possible to add a logo or text in the middle of the QR code? Preferably using the SVG plugin.

The easiest thing would be to simply run the resulting SVG code through an SVG library and simply overlay a logo or text with a white background on top of the QR code (making sure to not cover too much data points).

I'm a QR noob... I assumed that you could not cover any of it at all.

No, QR codes contain error correction data. The amount of redundant data depends on the selected error correction level. The highest level (H) can sustain a loss of up to 30%.
