[Description]
•
Sets the error correction level for PDF417.
•
When
m
= 48, the error correction level is set by the “Level Setting” and the “Ratio
Setting” is canceled. The number of error correction codewords are as follows:

When
m
= 49, the error correction level is set by the “Ratio Setting” to the level
indicated by the number for encoded data, and the “Level Setting” is canceled.
The rate is set to [
