PAdES Signatures and Long-Term Validation

With version 7.0 of Foxit PDF SDK, we have introduced support for PAdES (PDF Advanced Electronic Signatures), the official standard for the use of CAdES (CMS Advanced Electronic Signatures) in PDFs. Supporting LTV-Enabled signatures helps you deal with a series of archiving, compliance and legal issues when signing contracts, forms and any type of PDF. With Foxit PDF SDK 7.0, preserving and protecting these documents on a long-term basis is easier than ever.


The same functionality already available on other PDF SDK platforms is now available on .NET Core. The open source framework is ideal for those who develop apps on Windows, Linux, and Mac operating systems. With its high-performance and scalable system, .NET Core is the future of the .NET framework and you can develop your apps now in .NET Core with PDF SDK 7.0.

The mobile web viewer now offers the same experience as PC. The menu style adopts the same ribbon menu mode with all the features you get on the desktop version including a search tab, editing tab, protect tab, annotations, page turning component and more. The UI/UX smartly adjusts itself in accordance with the screen size.


AngularJS is Google’s open source JavaScript front end framework and is now compatible with PDF SDK for Web. This means you can now build a fully functioning web-based JavaScript PDF viewer with the framework of your choice. We now offer complete integration with AngularJS and powerful viewing and rendering SDK.

JavaScript functionality has been expanded in Foxit PDF SDK 7.0, providing new methods and properties focused on annotations. You are now able to add new annotations through a JS script, as well as retrieve single and multiple annotations properties using getAnnot and getAnnot methods.

In terms of properties, there is an array of new functionality available for customizing your annotations design such as type, opacity, fill and stroke color, textsize, alignment, rotate, setting readOnly state and much more. This is an exciting new functionality added to the previous form-related JavaScript methods. Now you can not only work on your PDF forms in JavaScript, but also annotate your PDFs with easily transferable JS code!

Take a look at the sample code below for adding an annotation once the file is saved:


#include "include/pdf/actions/fs_action.h" 
#include "include/pdf/annots/fs_annot.h" 

using namespace foxit; 
using namespace pdf; 
using namespace annots; 

// Load a document 

 PDFDoc doc = PDFDoc(input_file); 

 // Prepare Additional Action 

 AdditionalAction pAAction(doc); 
 if (pAAction.IsEmpty()) { 
 return err_ret; 

  // Create new Action of JavaScript type 

 Action new_action = Action::Create(doc, Action::e_TypeJavaScript); 
 if (new_action.IsEmpty()) { 
 return err_ret; 
 // Assign JavaScript action to new action 

 JavaScriptAction js_action = (JavaScriptAction)new_action; 
 if (js_action.IsEmpty()) { 
 return err_ret; 
 // Define the script to be used by the JavaScript action. You may copy and paste your script in the SetScript method parameter below and run different actions. 

 js_action.SetScript(L"var annot = this.addAnnot({ page: 0, type: \"Text\", point: [72, 30], popupRect: [72, 300, 3 * 72, 300 - 2 * 72], popupOpen: true, noteIcon: \"Help\"});"); 

 // Set the JavaScriptAction and the trigger event to the Action 

 pAAction.SetAction(AdditionalAction::e_TriggerDocWillClose, js_action); 

 // Execute the JavaScript action when the event is triggered on runtime 


 // Save PDF file 

 WString newPdf = output_directory + L"<your-saved-file-name>.pdf"; 
 doc.SaveAs(newPdf, PDFDoc::e_SaveFlagNoOriginal);
