Expand description
The different mask patterns. The mask pattern should only be applied to the data and error correction portion of the QR code.
Variants§
Checkerboard = 0
QR code pattern n°0: (x + y) % 2 == 0
.
HorizontalLines = 1
QR code pattern n°1: y % 2 == 0
.
VerticalLines = 2
QR code pattern n°2: x % 3 == 0
.
DiagonalLines = 3
QR code pattern n°3: (x + y) % 3 == 0
.
LargeCheckerboard = 4
QR code pattern n°4: ((x/3) + (y/2)) % 2 == 0
.
Fields = 5
QR code pattern n°5: (x*y)%2 + (x*y)%3 == 0
.
Diamonds = 6
QR code pattern n°6: ((x*y)%2 + (x*y)%3) % 2 == 0
.
Meadow = 7
QR code pattern n°7: ((x+y)%2 + (x*y)%3) % 2 == 0
