| # Complete working example: add barcode to an existing PDF | |
| from asposebarcode import BarcodeGenerator, EncodeTypes | |
| from asposebarcode.generator import BarCodeImageFormat | |
| from asposepdf import Document, ImageStamp | |
| # 1. Generate barcode image in memory | |
| barcode_generator = BarcodeGenerator(EncodeTypes.CODE_128, "INV-2023-001") | |
| barcode_generator.parameters.image.width = 300 | |
| barcode_generator.parameters.image.height = 100 | |
| barcode_stream = barcode_generator.generate_barcode_image(BarCodeImageFormat.PNG) | |
| # 2. Load the PDF you want to modify | |
| pdf_document = Document("invoice_template.pdf") | |
| # 3. Add the barcode to the first page | |
| page = pdf_document.pages[0] | |
| stamp = ImageStamp(barcode_stream) | |
| stamp.x = 50 # X coordinate (points) | |
| stamp.y = 700 # Y coordinate (points) | |
| stamp.width = 300 | |
| stamp.height = 100 | |
| page.add_stamp(stamp) | |
| # 4. Save the updated PDF | |
| pdf_document.save("invoice_with_barcode.pdf") |
