Defining Field Options 4-11
Using Option 51 (PDF417 Security/Truncation)
Define a security level and choose whether or not to truncate a PDF417 bar code. Higher security
levels add data to a bar code, improving scan reliability. Some damaged bar codes may still be
scannable if the security level is high enough. Use this option to create standard PDF417 bar
codes or use the truncated option to create a narrower bar code. This option can appear only
once per PDF417 field, in any order, following the bar code field.
As the security level is increased, so is the size of the PDF417 bar code. For each level
increased, the bar code doubles in size.
Syntax R,51,security,stand/default |
R1. R Option Header.
R2. 51 Indicates Option 51.
R3. security Security level ranges from 0 to 8. 0 is the default.
Higher security levels add data to a bar code, improving scan
reliability. Some damaged bar codes may still be scannable if the
security level is high enough.
R4. stand/def Truncation selector. S is the default. Valid values:
S a standard PDF417 bar code
T truncated
Example R,51,2,S |
Defines a security level of 2 for a standard PDF417 bar code.
Using Option 52 (PDF417 Width/Length)
This option defines the image width or length of a PDF417 bar code. If defining a fixed number of
columns (width), the bar code expands in length. If defining a fixed number of rows (length), the
bar code expands in width. Column value does not include start/stop or left/right indicator
columns. If this option does not immediately follow the PDF417 bar code field, the default
settings are used. Use this option once per PDF417 bar code field.
Syntax R,52,row/column,dimension |
R1. R Option Header.
R2. 52 Indicates Option 52.
R3. row/column Indicates the number of rows or columns. If rows are specified,
the bar code expands in columns, or vice versa.
R Row
C Column
R4. dimension The number of rows or columns defined for the bar code. Valid
values:
3-90 for rows. 3 is the default for rows.
1-30 for columns. 1 is the default for columns.
Example R,52,C,10 |
Defines the column width of 10, which expands the PDF417 bar code length by 10.
