Document Solutions for PDF 8.2.0

• AI-Powered PDF Processing - This release introduces a powerful new package, DsPdfAI, designed to showcase how Document Solutions for PDF can integrate with AI services to enhance PDF document workflows. This feature allows developers to leverage OpenAI or Azure OpenAI to generate summaries, create outline trees, and extract structured tables data directly from PDFs.
  • Supported Scenarios - Currently, DsPdfAI supports the following three AI-driven PDF processing capabilities:
    • Generate a Document Summary - Quickly produce short or long summaries of any PDF document.
    • Programmatically Generate a PDF Document Summary using DsPdfAI in C# or VB.
    • Build a Document Outline Tree - Automatically generate a structured table of contents, complete with nested outline levels.
    • Automatically generate a structured table of contents using AI capabilities included in a .NET PDF API.
    • Extract Tables from a Document - Use natural language prompts to identify and extract tabular data from a PDF.
    • Extract Tables from a PDF using PDF API AI Capabilities.
    • These features are built on top of the OpenAI Chat API, with options to connect either via the official OpenAI .NET client library or the Azure OpenAI service.
  • API Overview - The new package introduces two main classes, both inheriting from a shared base class for core functionality:
    • OpenAIDocumentAssistant - Connects to the OpenAI REST API using the official .NET client library.
    • AzureOpenAIDocumentAssistant - Connects to Azure OpenAI services using the Azure.AI.OpenAI package.
    • Both derive from OpenAIDocumentAssistantBase, which implements the logic for extracting text via Page.GetText() and sending content to the AI service for processing. The pageRange parameter allows developers to limit requests to specific sections of a PDF.
  • Platforms Supported:
    • OpenAI REST API (via the official .NET client).
    • Azure OpenAI Service (via the Azure.AI.OpenAI package).

These changes ensure that the most frequently used actions are easier to access, while still allowing backward compatibility for users who prefer the legacy layout.

Document Solutions for Word 8.2.0

• Update TOA and TA Fields - DsWord now provides APIs to work with TOA (Table of Authorities) and TA (Table of Authorities Entry) fields, making it easier to build and manage legal or reference-heavy documents programmatically.
  • The new ToaFieldOptions class enables developers to read and modify TOA field options, while the ToaPageNumberOptions class controls how page numbers are displayed. A CitationCategoryMap class has also been added to retrieve citation category names for more accurate categorization.
  • For TA fields, the new TaFieldOptions class allows reading and writing of TA field options, which define the text and page numbers or ranges for individual TOA entries. Together, these enhancements give developers full control to generate, update, and customize TOA and TA fields in Word documents.
• Get List of Template Tags Defined in the Document - DsWord now provides a new API to retrieve all template tags (placeholders such as {{CustomerName}}) defined in a Data Template. Using the DataTemplate.GetTemplateTagInfos() method, developers can obtain a list of TemplateTagInfo objects that provide details such as the tag's name, type, range, and text. This makes it easy to analyze or store placeholder information for reporting, data validation, or role-based permissions.
• Access Template Tags and Locations in the Exported PDF - When exporting a DsWord document to PDF, you can now mark template tag locations for accessibility, validation, or review. By setting WordLayoutSettings.MarkTemplateTagAreas = true, DsWord records the positions of template tags during layout. Developers can then use the PdfOutputSettings.MarkupTemplateTags delegate to add custom markup, such as PDF annotations, to highlight these tags on each page.
• Method GetTemplateTagInfos has been added to GrapeCity.Documents.Word.Templates.DataTemplate: Gets the list of TemplateTagInfo objects in the document.
• Enum TemplateTagType has been added to GrapeCity.Documents.Word.Templates: Specifies the type of a template tag.
• Class TemplateTagInfo has been added to GrapeCity.Documents.Word.Templates: Represents information about a template tag.

• Property MarkupTemplateTags has been added to GrapeCity.Documents.Word.Layout.PdfOutputSettings: Specifies a method to be executed for each PDF page during export, allowing custom markup to be added to template tags on the page.
• Class ToaFieldOptions has been added to GrapeCity.Documents.Word.Fields: Represents options for configuring a Table of Authorities (TOA) field.
• Class ToaPageNumberOptions has been added to GrapeCity.Documents.Word.Fields: Represents options that control how page numbers are displayed in the result of a Table of Authorities (TOA) field.
