This was forwarded to me by one of my coworkers...I wonder if anyone has some experience and possible insight onthe issue here...
Below is the content of what we are currently trying to do with iText. *PROBLEM:* Read an existing PDF, populate form field values and change form fields to Read-Only. *SOLUTION:* According to several references, it looks like it should be possible to use the setFieldProperty method of AcroFields Class. *RESULTS:* Currently, form field values are updated correctly, but we are not able to change the Read-only property. *REPORTING ENVIRONMENT* ColdFusion: 7.x (using JVM 1.4x) iText: 2.1.7 Acrobat PDF: v6+ Files *CODE REFERENCES* Read-Only Example: http://www.itextpdf.com/examples/index.php?page=example&id=161 AcroFields Reference: http://tom.tharrisx.homedns.org/sm3rdpartyref/itext-docs-2.0.4/com/lowagie/text/pdf/AcroFields.html *ColdFusion Source Code* <cfscript> //---------------------------------------------------------------------------------- // FILENAME: iText_demo.cfm // PURPOSE: Populate form fields and make a field Read Only using iText v2.1.7 library. // // CREATED: 03/05/2010 //---------------------------------------------------------------------------------- fullPathToInputFile = expandpath("testTemplate.pdf"); // full path to PDF you want to modify // full path to the PDF we will output.
