GS1 Digital Link QR Code - bwipp/postscriptbarcode GitHub Wiki

GS1 Digital Link QR Code is an implementation of the QR Code barcode symbology containing a GS1 Digital Link URI.

Variants:

• GS1 QR Code encodes GS1 data in Application Identifier format.

Standards: ISO/IEC 18004, ITS - QR Code, GS1 Digital Link Standard: URI Syntax.

• The data field input is provided as a GS1 Digital Link URI.
• The includetext option enables the display of HRI.
• Deprecated. The dontlint option disables GS1 Application Identifier syntax validation allowing images to be generated for input that does not comply with GS1 standards.
• The eclevel option is used to specify the error correction level:
  • eclevel=L - Low
  • eclevel=M - Medium (default)
  • eclevel=Q - Quality
  • eclevel=H - High
• The fixedeclevel option will prevent the error correction level from being opportunistically raised when a better fix to the current matrix is possible.
• The version option is used to specify the size of the symbol, 1 to 40.
• If the version is unspecified the encoder will default to creating a symbol that is the minimum size to represent the given data at the selected error correction level.

A GS1 Digital Link URI containing GTIN and additional data:

Data:    https://id.gs1.org/01/09521234543213/22/ABC%2d123?99=XYZ%2f987
Options:
Encoder: gs1dlqrcode

With human readable interpretation:

Data:    https://id.gs1.org/01/09521234543213/22/ABC%2d123?99=XYZ%2f987
Options: includetext
Encoder: gs1dlqrcode

Note: By default, the HRI displays only the primary key extracted from the Digital Link URI.

With full AI extraction into multiline HRI:

Data:    https://id.gs1.org/01/09521234543213/10/ABC123/21/12345
Options: includetext alttext=(01)~09521234543213|(10)~ABC123|(21)~12345
         alttextsubspace=~ alttextsplit=| textxalign=offright textxoffset=5
         textyalign=center
Encoder: gs1dlqrcode
