Enum qrcode::canvas::MaskPattern

pub enum MaskPattern {

The mask patterns. Since QR code and Micro QR code do not use the same pattern number, we name them according to their shape instead of the number.

Variants

Checkerboard = 0

QR code pattern 000: (x + y) % 2 == 0.

HorizontalLines = 1

QR code pattern 001: y % 2 == 0.

VerticalLines = 2

QR code pattern 010: x % 3 == 0.

DiagonalLines = 3

QR code pattern 011: (x + y) % 3 == 0.

LargeCheckerboard = 4

QR code pattern 100: ((x/3) + (y/2)) % 2 == 0.

Fields = 5

QR code pattern 101: (x*y)%2 + (x*y)%3 == 0.

Diamonds = 6

QR code pattern 110: ((x*y)%2 + (x*y)%3) % 2 == 0.

Meadow = 7

QR code pattern 111: ((x+y)%2 + (x*y)%3) % 2 == 0.
