PDF reading and writing capabilities in viewer components are essential for applications that handle document management or display. These features allow developers to integrate PDF interaction directly into web or desktop applications, enabling end-users to open, view, annotate, and sometimes even modify PDF files without relying on external software. By supporting both the consumption and output of PDF content, these components improve workflows across document-heavy environments, such as enterprise reporting, legal systems, and educational platforms.

Common features include:

  • Printing/saving to PDF allows users to convert viewed documents or application content into PDFs or store existing files for offline access.
  • Printing PDFs to a printer enables direct output of documents to physical printers with accurate formatting and pagination.
  • Localization ensures the viewer interface adapts to multiple languages, facilitating global user adoption.
  • Right to Left (RTL) support is critical for users of languages such as Arabic or Hebrew, aligning UI and text layout appropriately.
  • Searching text provides in-document search capabilities, letting users find specific terms or phrases quickly within large PDFs.
  • Opening existing PDFs from stream allows developers to load documents directly from memory or server streams, improving performance and enabling secure or dynamic content delivery.

.NETのPDF処理アプリでOCRを有効化

6月 27, 2025
Telerik Document Processing Libraries 2025 Q2 Updateでは、光学式文字認識(OCR)のサポートによりPDF処理ライブラリを強化

Telerik Document Processing is a suite of document processing libraries designed for web, desktop and cross-platform .NET applications. It enables developers to create, read, edit, and convert a wide range of document formats, including PDF, DOCX, XLSX, ZIP and HTML, without relying on external software such as Microsoft Office or Adobe Acrobat. These libraries are independent from the user interface (UI) and are built for high performance and accuracy, providing convenient APIs that give flexibility and control so you can integrate document processing capabilities into your applications with only a few lines of code.

The Telerik Document Processing Libraries 2025 Q2 (2025.2.520) update adds Optical Character Recognition (OCR) support to the PDFProcessing library, enabling developers to extract machine-readable text from scanned PDFs and images directly within .NET applications. This functionality facilitates the conversion of previously inaccessible content, such as scanned contracts, forms or handwritten notes, into editable and searchable machine-encoded text, providing users with extracted text along with a PDF containing the image with selectable text. By integrating OCR capabilities, developers can now streamline data extraction and analysis tasks, reducing the need for manual data entry and improving overall efficiency in handling diverse document types.

To see a full list of what's new in 2025 Q2 (2025.2.520), see our release notes.

Telerik UI is licensed per developer and has two licensing models: an annual Subscription License and a Perpetual License. The Subscription license provides access to the latest product updates, technical support, and exclusive benefits for a flat annual fee, and must be renewed to continue using the software. The Perpetual license is a one-time purchase granting access to the current released version and includes a one-year subscription for product updates and technical support. After this initial period, users can choose to renew the subscription element to continue receiving updates and support; otherwise, they may continue using the installed version available during their active subscription term but will forgo future updates and support. See our Telerik DevCraft Ultimate licensing page for full details.

The Telerik Document Processing Libraries are available in the following products:

印刷してPDFに保存すると、動作環境に関係なく、アプリケーションで信頼性の高い高品質のドキュメントを生成可能

Printing to PDF allows users to save an existing document, webpage, or file as a PDF by using a virtual printer. It captures the document exactly as it would appear if printed, preserving the formatting, layout, and styling. The resulting document is typically static and cannot be edited, ideal for archiving or sharing finalized versions of a document. This feature is particularly useful for standardizing outputs across different software, ensuring consistent presentation, and providing an easy way to generate PDFs from files that do not natively support the format.

Several WinForms PDF controls offer the ability to print/save to PDF including:

  • Telerik UI PDF for WinForms (part of Telerik UI for WinForms) enables developers to print or export UI content directly to PDF files with layout fidelity and output options.
  • ComponentOne Studio WinForms PDF (part of ComponentOne Studio WinForms by MESCIUS) offers native support for saving forms, controls, and reports as PDF.
  • LEADTOOLS PDF provides a robust API for printing or exporting documents to PDF, supporting both vector and raster content, with configurable print settings and security options.
  • ImageGear for .NET by Accusoft allows saving rendered documents or image-based content directly to PDF formats, with control over compression and output resolution.

PDF内で直接編集可能なフィールドを許可し、迅速かつ効率的なデータ入力を可能にすることで、ユーザーの操作を強化

Form filling in a PDF Viewer enables users to interact with editable fields such as text boxes, checkmarks, radio buttons, and selection lists - right inside the document. This functionality is ideal for scenarios like contracts, surveys, and registration forms, where structured input is essential. By integrating these capabilities, developers can improve user interactions and allow form submission without leaving the application, enhancing data capture and eliminating the need for external tools.

Several WPF PDF Viewers feature support for form filling, including:

  • Telerik UI PDF for WPF (part of Telerik UI for WPF) enables editable text, checkboxes, radio buttons, and saving completed PDF forms.
  • DevExpress WPF PDF Viewer (part of DevExpress WPF) allows you to fill, highlight, import, and export PDF form fields.
  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) allows you to fill PDF forms with text fields, checkboxes, and dropdowns.

組み込みのナビゲーションツールを使用すると、ユーザーはPDFドキュメントを簡単に移動できるため、複雑なファイルでも簡単にアクセスして理解可能

PDF navigation features play a crucial role in enhancing the usability and accessibility of digital documents. In modern PDF components, navigation tools are designed to provide intuitive access to document content, helping users locate specific sections, pages, or topics quickly. These tools are particularly important in lengthy or complex PDFs such as manuals, reports, and eBooks, where efficient navigation can significantly improve the reading experience and reduce time spent searching for information.

Common features include:

  • Bookmark navigation allows users to jump to predefined sections through a sidebar of bookmarks that often mirrors the document's structure.
  • Hyperlink navigation supports both internal links within the document and external web links, facilitating direct access to related information or resources.
  • Table of Contents navigation mirrors traditional print documents by listing chapters or sections with interactive links, helping users to understand the document's structure at a glance and move directly to areas of interest.
  • Thumbnail navigation provides visual page previews, enabling users to scroll through and select pages more easily, especially in graphically rich or page-specific content.
