AutoIt Requires Chilkat v11.7.0+

What PDF Text Replacement Does Not Change: Metadata, Links, Form Fields

See more PDF Text Replacement Examples

TextReplace changes the page content only. A placeholder that also appears in the document's metadata (the Title, Author, Subject, Keywords, Creator or Producer), in a link's target URL, or in a form field's value is left as it is and reported in "notReplaced" with "where" saying which. The invoice template's title is "Invoice for {{customer}}" and its "View this invoice online" link points at a URL that holds {{customer}}. AutoIt
