Overwriting existing files

(mPDF ≥ 2.3)

Using Overwrite() function, an existing PDF file can be overwritten, replacing specified text with alternatives. For example you may have created a long complex PDF file, and you wish to produce copies with an individual number on each copy without having to re-generate the whole document each time.

Use first SetImportUse() to enable pdf import functions.

Note: OverWrite() was written to work on PDF files produced by mPDF. It will work with encrypted files, as long as the same encryption properties are used for the new document. I have also used it successfully with a number of external PDF files, including those produced by Acrobat Distiller (but not if they are encrypted). It will not work with embedded font subsets.
