I made the changes to XmpReader and XmpWriter and have been trying on my own to mess with it the last couple of days, but I am not doing something right.
Earlier with iText 2.1.5, I tried the overlay with a PDF/A-1b document (attached here as Good_PDFA_1b.pdf) created using Adobe Pro 9 and the output was still a PDF/A-1b. But now after the changes to the two java programs, executing the app against this PDF/A-1b displays the following message: [Fatal Error] :94:2: The markup in the document following the root element must be well-formed. [Fatal Error] :94:2: The markup in the document following the root element must be well-formed. I then tried to run the app against the PDF/A-1b created by our vendor (which has the PI tags missing) and I get this error message: [Fatal Error] :5:17: The prefix "xmp" for element "xmp:ModifyDate" is not bound. [Fatal Error] :5:17: The prefix "xmp" for element "xmp:ModifyDate" is not bound. If this makes any sense to you guys, I would really appreciate your input. I have attached the two java source files (trunk/src/core/com/lowagie/text/xml/xmp/XmpReader.java, http://www.nabble.com/file/p23966132/Good_PDFA_1b.pdf Good_PDFA_1b.pdf trunk/src/core/com/lowagie/text/xml/xmp/XmpWriter.java) as well Attached files: http://www.nabble.com/file/t799222/Good_PDFA_1b.pdf http://www.nabble.com/file/t799222/XmpWriter.java http://www.nabble.com/file/t799222/XmpReader.java 1T3XT info wrote: > > ek1975 wrote: >> I didn't request that you fix anything for me. > > It sounded that way.
