Error Recovery Levels

Level	Recovery Capacity
low	~7%
medium	~15%
high	~25%
highest	~30%

Higher recovery levels create larger QR codes but can recover from more damage.

Notes

• The QR code is rendered using ANSI background colors
• Works best in terminals that support ANSI color codes
• Use -i (invert) if scanning is difficult with your terminal's color scheme
