Adding HTML Content Efficiently

IronPDF for Python supports applying multiple different stamps — HTML, text, image, and barcode — to a PDF document in a single operation using ApplyMultipleStamps.

Getting Started

Create individual stamper objects for each stamp type, add them to a List[Stamper] collection, then call ApplyMultipleStamps on a PdfDocument to apply all stamps at once.

Understanding the Code

HtmlStamper(html): Stamps an HTML fragment onto the PDF. Supports VerticalOffset and HorizontalOffset to fine-tune position using pixel-based Length values.
TextStamper(text): Stamps plain text with custom font settings. Set UseGoogleFont = True and FontFamily to use any Google Font by name.
ImageStamper(path): Stamps an image file onto the PDF. Use MinWidth and MinHeight to control the stamp dimensions.
BarcodeStamper(value, encoding): Generates and stamps a barcode or QR code. BarcodeEncoding.Code39 produces a standard Code 39 barcode.
List[Stamper](): A typed collection that holds stamper objects of mixed types.
ApplyMultipleStamps(stamps_list): Applies all stamps in the list to every page of the document in a single efficient pass.
