QRCode.Placement (QRCode v2.2.1) View Source

A patterns are a non-data element of the QR code that is required by the QR code specification, such as the three finder patterns in the corners of the QR code matrix.

It contains function patterns (finder patterns, timing patterns, separators, alignment patterns) and reserved areas (format information area, version information area).
