    Remarks
    Additional grades for Data Matrix barcode (defined in ISO 16022 Annex M):
    • FixedPatternDamage.L1 - Grade of segment L1 (see below).
    • FixedPatternDamage.L2 - Grade of segment L2 (see below).
    • FixedPatternDamage.QZL1 - Grade of segment QZL1 (see below).
    • FixedPatternDamage.QZL2 - Grade of segment QZL2 (see below).
    • FixedPatternDamage.Segment_X_Y_Top - Grade of top alignment patterns (clock track and solid area) of data region located by specified indexes (X, Y).
    • FixedPatternDamage.Segment_X_Y_Right - Grade of right alignment patterns (clock track and solid area) of data region located by specified indexes (X, Y).
    • FixedPatternDamage.ClockAndSolidArea - Grade of all alignment patterns of data regions.
    • FixedPatternDamage.AG - Grade of average grade of L1, L2, QZL1, QZL2, ClockAndSolidArea.

    Segment L1 is the vertical portion of the L and extends to the module in the quiet zone adjacent to the L corner. Segment L2 is the horizontal portion of the L and extends to the module in the quiet zone adjacent to the L corner. Segments QZL1 and QZL2 are the portions of the quiet zone adjacent to L1 and L2 respectively and extend one module beyond the end of L1 and L2 respectively, furthest from the corner.

    Additional grades for Han Xin Code Matrix barcode (defined in specification):
    • FixedPatternDamage.A1 - Grade of 11x11 in symbol left top corner (finder pattern and quiet zone).
    • FixedPatternDamage.A2 - Grade of 11x11 in symbol right top corner (finder pattern and quiet zone).
    • FixedPatternDamage.A3 - Grade of 11x11 in symbol right bottom corner (finder pattern and quiet zone).
    • FixedPatternDamage.A4 - Grade of 11x11 in symbol left bottom corner (finder pattern and quiet zone).
    • FixedPatternDamage.B - Grade of Alignment Pattern and Assistant Alignment Pattern.
    • StructuralInformationRegion.Region1 - Grade of Structural Information Region 1 (left top and right top).
    • StructuralInformationRegion.Region2 - Grade of Structural Information Region 1 (left bottom and right bottom).
    • StructuralInformationRegion.Region - Grade of Structural Information Region 1 and Region 2.
