How to Insert a Barcode into a PDF Document

With GroupDocs.Assembly, you can easily embed barcodes into PDF templates. Supports 1D and 2D barcode formats including QR, Code 128, Data Matrix, and more.

Design your template using supported tags (note: PDF-based templates are not yet supported).
Pull structured data from your preferred source (e.g., JSON, XML, databases).
Customize barcode settings such as size, resolution, or symbology.
Export the completed document as a PDF file with the barcode.

Example document Copy

# Use this tag in your template to automatically generate and insert a barcode
# <<barcode [barcode_expression] -barcode_type>>

import groupdocs.assembly as ga

    def run():

        # Define the path to your template file
        template = "barcode_template.pdf"

        # Connect to your preferred data source
        data = ga.DataSourceInfo(GetData(), "label")

        # Generate the final document with the embedded barcode
        asm = ga.DocumentAssembler()
        asm.assemble_document(template, "result.pdf", data)

            ga.data.CsvDataLoadOptions(True))

        # Construct a data object with only relevant fields
        data = ga.DataSourceInfo(data_csv, "label")

        # Initialize the DocumentAssembler instance
        asm = ga.DocumentAssembler()

        # Define barcode-specific properties (e.g., type, size)
        asm.barcode_settings.resolution = 1200
        asm.barcode_settings.base_y_dimension = 5

        # Save the completed document with the barcode inserted
