问题 I am getting the following errors while trying to convert PDF(XFA) to string. These errors started coming when I switched from PDFBox 1.8.12 to PDFBox 2.0.4 Here is the log Mar 09, 2017 7:16:07 AM org.apache.pdfbox.pdfparser.BaseParser parseCOSArray WARNING: Corrupt object reference at offset 779916 Mar 09, 2017 7:16:07 AM org.apache.pdfbox.pdfparser.BaseParser parseCOSArray WARNING: Corrupt object reference at offset 780049 Mar 09, 2017 7:16:07 AM org.apache.pdfbox.pdfparser.BaseParser

XFA values initially invisible when AcroForm values are set

问题 I want to fill out a dual AcroForm/XFA PDF form automatically. I included an XFA dataset packet and all values showed up in Adobe Reader. I set the V= key in AcroForms entries to the new value and all values showed up alternative PDF readers. However, when I open the PDF with XFA and AcroForm V= entries in Adobe Reader, only the value of the text field that is currently selected is visible: I cannot find any mention in the PDF specification of a special flag to set when AcroForms and XFA are

Digital Signing of XFA forms

由 痴心易碎 提交于 2019-12-10 12:14:45
问题 I'd like to sign PDF documents created in Adobe Livecycle (it is XFA form) programmatically. I know about iText library for manipulating with PDFs, but I haven't found any example how to sign it yet. Maybe its not supported yet. Do you know any other Java library which can do that? Or do you know a way how to sign it? I know, my question is similar to this opened question, but I don't need the use of iText. Thank you very much for your help! 回答1: This is a small example showing how to sign

AcroField changes made using itext7 in C# do not commit/are not visable due to hybrid AcroForm-XFA issues

问题 Project is to fill existing forms programmatically from a database/datagridview and allow the user to edit the forms afterwards as the database does not hold all values needed. I am able to get the values, and put them into the form however: Values set using AcroForms do not show/print when viewing form. Background color change does not show when viewing form. Both changes appear when clicking into the field. I understand this is caused by hybrid XFA and AcroForms issues, and that pdfXFA is a

How to calculate the checksum in an XFA form

由 这一生的挚爱 提交于 2019-12-09 06:50:56
问题 When you save an XFA form (XFA = XML Forms Architecture) using Adobe software, a checksum attribute is added to the form element. This checksum appears to be a SHA-1 digest, but it's unclear as to what is actually fed to the hash. Does anyone have any idea as to how this is generated? This value is needed by Adobe Acrobat to validate what's actually in the form's XML data, but when I create a hash of the XML that is being fed to the form, Adobe Acrobat doesn't accept it. This checksum

How To programmatically detect XFA (Adobe XML Forms Architecture) dynamic PDF

由 泄露秘密 提交于 2019-12-08 05:02:57
问题 I have a system that converts pdf to tif. Basically it's a program written in csharp that uses iTextSharp to get metadata about the pdf and pdf2tif (http://pdftotif.sourceforge.net/) to convert to the file. I've noticed a number of pdf's do not convert correctly. In Acrobat and Foxit they open as multi page forms but in any other viewer (Ghostscript...) they open as 1 page documents with the message "To view the full contents of this document, you need a later version of the PDF viewer. You

Detect dynamic XFA with iText

问题 I need to make pre-populated PDF/XFA forms read-only (as in no inputs, such as text, checkboxes, radio buttons etc. can have their values changed). For regular AcroForms PDFs and static XFA forms, I can accomplish this by calling setFormFlattening(true) on the PdfStamper instance. For dynamic XFA forms, I have to set an access attribute of the XDP's field node to be readOnly . The problem is, how do I detect if a form is dynamic XFA? isXfaPresent doesn't differentiate between static or

Extract xdp or xfa from PDF

问题 I created a PDF form with Adobe LiveCycle Designer. I'm now struggling to extract the data programmatically from the PDF after it's been filled out. I tried to do this using poppler (the qt4 binding, but I guess that doesn't matter), but apparently poppler can't handle XFA forms. Although evince and okular are able to display the form... As far as I understand, the PDF contains an XDP which in turn contains the XFA form. My question is, how can I extract that data from the PDF? If there are
