How to embed a barcode in a PDF document

GroupDocs.Assembly lets you insert barcodes into popular formats like PDF templates. Supports over 60 types, including 1D and 2D barcodes.

Prepare a template with placeholders for barcodes (PDF templates are not supported).
Fetch data from a supported source.
Adjust barcode settings such as size and resolution.
Save the document with the added barcode as a PDF file.

Example document Copy

// Use this tag in your template to create a barcode in the output document
// <<barcode [barcode_expression] -barcode_type>>

// Set the file path for the template
// PDF templates are currently not supported.
String template = "barcode_template.docx";

// Fetch data from your source
DataSourceInfo data 
    = new DataSourceInfo(GetData(), "label");

// Save the document with the added barcode as a PDF file.
DocumentAssembler asm = new DocumentAssembler();
asm.assembleDocument(template, "result.pdf", data);
