使用TCPDF在现有PDF上生成条形码

I used to dynamically create PDF documents and barcodes with HTML using TCPDF.

To generate the barcode options the serializeTCPDFtagParameters method is used and later <tcpdf method="write1DBarcode" params="PARAMS" /> is passed to the PDF's HTML.

Now, I need to generate a barcode and then insert on each page of an existing PDF template.

Is it possible to generate a barcode for an existing PDF using TCPDF library?
