用书签将导航功能添加到 PDF

12月 10, 2025
带有书签导航的 .NET PDF 组件允许用户快速跳转到复杂多页文档中的特定内容。

Bookmark navigation in a .NET PDF control allows users to access and move through predefined sections within a PDF document using a hierarchical list of bookmarks. While commonly used for chapters, bookmarks can also point to tables, figures, appendices, or any specific content, enabling flexible navigation across various elements of a document. Developers can create bookmarks dynamically based on document structure, metadata, or application logic, making it easier to guide users through complex content or highlight specific areas of interest.

Several .NET PDF components offer bookmark navigation including:

  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) allows developers to programmatically add, edit, and remove bookmarks in PDFs.
  • Document Solutions for PDF by MESCIUS enables .NET apps to manage bookmarks so users can jump directly to pages, sections, or content elements in complex PDFs.
  • Aspose.PDF for .NET allows insertion and manipulation of PDF bookmarks so users can navigate to sections, headings, or customized targets efficiently.
  • Telerik UI for WPF PdfProcessing (part of Telerik UI for WPF) supports bookmarks in PDF documents, enabling hierarchical navigation inside .NET applications.

BFO PDF Library v2.29.4 通过改进对复杂信任链的支持确保企业 PDF 流程中数字签名验证的可靠性。

The BFO PDF Library by Big Faceless Organization is a high-performance Java toolkit for creating, editing, and displaying PDF documents programmatically. Designed for developers who need to generate or manipulate PDFs dynamically, it supports features such as PDF/A and PDF/X compliance, digital signatures, encryption, and complex layout capabilities including tables, charts, and barcodes. The library integrates seamlessly into Java applications and is often used in enterprise environments where reliable, scalable PDF output is required. It also includes a viewer component for rendering PDFs within Java user interfaces, making it suitable for both backend document generation and client-side display.

The Big Faceless PDF Library v2.29.4 update improves digital signature validation by enhancing support for “cross-signed” trust chains, where the signer's certificate is issued by an intermediary certificate authority rather than directly by a root authority. This change makes the validation process more reliable in enterprise and real-world environments, where certificate chains often include intermediate signers or alternate trust paths. By better recognizing and resolving these chains, the library reduces the likelihood of false negatives during signature checks, ensuring a more accurate reflection of a document’s authenticity. This enhancement is particularly useful for developers integrating PDF processes in regulated or compliance-heavy contexts, where accurate and consistent signature validation is critical.

To see a full list of what's new in v2.29.4, see our release notes.

Big Faceless PDF Library is licensed per server/machine and is available as an annual or a perpetual license depending on the use case. Technical support is available. See our Big Faceless PDF Library licensing page for full details.
