Code39Settings

Defines options for the detection and output of Code 39 barcodes.

Remarks

The 'Code 39 Settings' object provides advanced configuration for how Code 39 barcodes are detected and decoded by barcode readers in Grooper. These options allow you to control support for full ASCII encoding, the handling of start/stop delimiters, and output formatting.

Use Code 39 Settings to match the encoding and formatting of Code 39 barcodes in your documents, ensuring accurate detection and correct output values. Adjust these options based on your barcode printing standards and the requirements of downstream processes.

Usage and Configuration

• Enable 'Full ASCII' if your barcodes encode the full ASCII character set.
• Use 'Include Start/Stop' to control whether delimiters appear in output values.
• Set 'Start/Stop Optional' if barcodes may be missing start/stop characters.

These settings are typically accessed as a property of a [1D Reader] or Standard Reader when Code 39 symbology is enabled.

Example Scenarios

• For barcodes using only uppercase letters and digits, leave 'Full ASCII' disabled.
• For barcodes printed without start/stop characters, enable 'Start/Stop Optional'.
• To output values exactly as encoded (including delimiters), enable 'Include Start/Stop'.

Properties

Name	Type		Description
Full ASCII	Boolean	►	Enables or disables support for full ASCII encoding in Code 39 barcodes. DefaultFalse The 'Full ASCII' property determines whether Grooper will interpret barcodes using the full 128-character ASCII set. Standard Code 39 supports only 43 characters (0-9, A-Z, and -. $/%+*). Full ASCII mode encodes additional characters as two-character sequences using $, %, +, and / as escape codes. Usage and Configuration Enable if your barcodes may contain lowercase letters, punctuation, or other ASCII characters. Leave disabled for standard Code 39 barcodes (uppercase letters, digits, and a few symbols). Impact Enabling allows decoding of a wider range of values, but may increase the risk of false positives if not required. Disabling restricts decoding to the standard Code 39 character set. Example Enable for barcodes containing values like a123$%. Disable for barcodes containing only A123-XYZ.
Include Start Stop	Boolean	►	Controls whether start/stop delimiters are included in the output value. DefaultFalse The 'Include Start/Stop' property determines if the asterisk (*) start and stop characters are included in the output value returned by the barcode reader. Usage and Configuration Enable to include delimiters in the output (e.g., *CODE39*). Disable to output only the encoded value (e.g., CODE39). Impact Including delimiters may be required for certain downstream systems or validation routines. Excluding delimiters is standard for most data extraction and indexing scenarios. Example Enable if your workflow expects output in the format *12345*. Disable for output like 12345.
Start Stop Optional	Boolean	►	Specifies whether start/stop delimiters are optional during detection. DefaultFalse The 'Start/Stop Optional' property allows Grooper to detect and decode barcodes even if the start (*) and stop (*) delimiters are missing from the printed barcode. Usage and Configuration Enable if your documents may contain Code 39 barcodes without start/stop characters. Disable to require strict adherence to the Code 39 standard. Impact Enabling increases flexibility but may increase the risk of false positives. Disabling enforces stricter validation, reducing false positives but possibly missing some barcodes. Example Enable for barcodes printed as 12345 (no delimiters). Disable for barcodes printed as *12345*.
