Functions

func MaskUtil_applyMaskPenaltyRule1

func MaskUtil_applyMaskPenaltyRule1(matrix *ByteMatrix) int

MaskUtil_applyMaskPenaltyRule1 Apply mask penalty rule 1 and return the penalty. Find repetitive cells with the same color and give penalty to them. Example: 00000 or 11111.

func MaskUtil_applyMaskPenaltyRule2

func MaskUtil_applyMaskPenaltyRule2(matrix *ByteMatrix) int

MaskUtil_applyMaskPenaltyRule2 Apply mask penalty rule 2 and return the penalty. Find 2x2 blocks with the same color and give penalty to them. This is actually equivalent to the spec's rule, which is to find MxN blocks and give a penalty proportional to (M-1)x(N-1), because this is the number of 2x2 blocks inside such a block.

func MaskUtil_applyMaskPenaltyRule3

func MaskUtil_applyMaskPenaltyRule3(matrix *ByteMatrix) int

MaskUtil_applyMaskPenaltyRule3 Apply mask penalty rule 3 and return the penalty. Find consecutive runs of 1:1:3:1:1:4 starting with black, or 4:1:1:3:1:1 starting with white, and give penalty to them. If we find patterns like 000010111010000, we give penalty once.

func MaskUtil_applyMaskPenaltyRule4

func MaskUtil_applyMaskPenaltyRule4(matrix *ByteMatrix) int

MaskUtil_applyMaskPenaltyRule4 Apply mask penalty rule 4 and return the penalty. Calculate the ratio of dark cells and give penalty if the ratio is far from 50%. It gives 10 penalty for 5% distance.

func MaskUtil_getDataMaskBit

func MaskUtil_getDataMaskBit(maskPattern, x, y int) (bool, error)

MaskUtil_getDataMaskBit Return the mask bit for "getMaskPattern" at "x" and "y". See 8.8 of JISX0510:2004 for mask pattern conditions.

func MatrixUtil_buildMatrix

func MatrixUtil_buildMatrix(
	dataBits *gozxing.BitArray,
	ecLevel decoder.ErrorCorrectionLevel,
	version *decoder.Version,
	maskPattern int,
	matrix *ByteMatrix) error

MatrixUtil_buildMatrix Build 2D matrix of QR Code from "dataBits" with "ecLevel", "version" and "getMaskPattern". On success, store the result in "matrix" and return true.

func QRCode_IsValidMaskPattern

func QRCode_IsValidMaskPattern(maskPattern int) bool
