m = 49, n = 1 [ratio: 10%]

[Description]

Sets the error correction level for PDF417.
m
Function
48
The error correction level is set by "level."
In this case, the error correction level set by the "Ratio Setting"is canceled.
49
The error correction level is set by "ratio." The ratio is[n × 10%].
In this case, the error correction level set by the "Level Setting" is canceled.

[Notes]

  • Settings of this function affect the processing of GS ( k   <Function 081> and GS ( k   <Function 082> .
  • Error correction level is specified by either "level" or "ratio."
  • Error correction level specified by "level" (m = 48) is as follows. In this case, the error correction level set by the " Ratio Setting" is canceled. The number of the error correction codeword is fixed regardless of the number of codewords in the data area.

  • Error correction level specified by "ratio" (m = 49) is as follows. The error correction level is defined by the calculated value [number of data codeword × n × 0.1 = (A)]. The number of the error correction codeword is changeable in proportion to the number of the codeword in the data area.
