利用 PDF 搜索快速查找文本，帮助用户定位关键词、浏览文档并立即访问相关内容。

Search in a PDF viewer allows users to quickly locate specific words, phrases, or data within a document without manually scanning each page. By instantly highlighting and navigating between results, search makes it easier to work with large or complex PDFs such as reports, manuals, contracts, or research papers. This functionality improves productivity by helping users find relevant information faster, understand content in context, and move directly to important sections.

Several .NET PDF Viewer controls allow you to search for text in PDF files including:

  • Telerik UI for .NET MAUI PDF Viewer (part of Telerik UI for .NET MAUI) lets you quickly search text highlight matches and navigate results across pages.
  • IronPDF for .NET by Iron Software allows you to programmatically search PDF text, identify keywords and extract relevant content.
  • ImageGear for .NET by Accusoft facilitates fast text search within PDF pages enabling applications to locate phrases highlight results and guide navigation.
  • GroupDocs.Viewer for .NET lets developers search text across viewed PDF documents quickly find matches and display highlighted results within applications.

在 PDF 文档中生成 QR 码和其它 2D 条码，以支持可靠的数据采集、跟踪和自动化流程。

The ability to render 2D barcodes using a PDF component refers to the capability to generate and embed two-dimensional barcodes, such as QR codes, Data Matrix, or PDF417, directly within PDF documents at creation time. This functionality allows developers to programmatically encode structured data, URLs, identifiers, or transactional information into machine-readable symbols that are accurately rendered as vector graphics or high-resolution images within the PDF. This supports use cases such as document tracking, authentication, inventory management, ticketing, and automated data capture in enterprise systems.

Several .NET PDF components allow you to create 2D barcodes, including:

  • Document Solutions for PDF by MESCIUS lets you generate QR Code and Data Matrix barcodes within PDFs as scalable vectors or raster images.
  • DevExpress PDF Document API for .NET (part of DevExpress Office File API) allows you to embed high-quality 2D barcodes in PDF files.
  • PDF4NET by PDF4DEV Solutions facilitates creating and integrating QR Code and Data Matrix barcodes into PDFs with flexible vector and raster output.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) enables you to produce standards-compliant 2D barcodes in PDFs.

直接在查看器中输入并提交交互式 PDF 表单，从而减少了手工步骤，提高了数据准确性。

Filling forms in a PDF viewer lets users complete interactive fields such as text boxes, checkboxes, radio buttons, and dropdowns directly in the document, without needing additional software. The viewer captures data in a structured format, which can help reduce entry errors and eliminate the need to print and scan forms. As a result, documents can be completed and returned more quickly, supporting paperless processes and simplifying day-to-day operations for both organizations and end users. Common use cases include contracts and agreements, job applications and onboarding forms, customer intake documents, compliance paperwork, and internal approval processes.

Several .NET PDF Viewers feature support for form filling, including:

使用内置或自定义印章注释为审批和工作流程提供一致的视觉指示。

Stamp annotation support in a PDF Viewer component allows applications to place predefined or custom visual marks, such as “Approved,” “Draft,” or date-based stamps, directly onto PDF pages as non-destructive annotations. For software developers, this capability simplifies the implementation of document review and approval processes by enabling users to apply consistent, repeatable markings without altering the underlying content. It improves traceability and collaboration by making document status and actions immediately visible, supports automation through programmatic stamp placement, and helps maintain document integrity while meeting common business and compliance requirements.

Several .NET PDF viewer components support stamp annotations, including:

  • Document Solutions for PDF by MESCIUS lets you add stamp annotations, in the PDF Viewer, to indicate status without content changes.
  • XFINIUM.PDF CROSS PLATFORM EDITION allows you to place predefined and custom stamp annotations, through its PDF Viewer, for clear review and approval marking.
  • PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates applying stamp annotations, helping applications visually communicate decisions without altering files.
  • Syncfusion ASP.NET Core PDF Viewer (part of Syncfusion Essential Studio Enterprise) allows you to implement stamp annotation support, enabling consistent status indicators.
