It would be great if TCPDF could be used to open an existing (previously created) PDF document, then search and replace text. At some point support for images would be nice, but text would be a great start. I know there is a FPDI related product that does this, but it would great if TCPDF could do it as well.
The tcpdf parser class is able to extract information from an existing PDF document but the import function for TCPDF is not yet complete.
