ビューアを通じてPDFコンテンツをキャプチャ

アプリがPDF文書からユーザーが選択したテキストや範囲を直接抽出できるようにし、取得したデータを画面上の可視的な操作と一致

Extracting content using a PDF Viewer refers to enabling end users or applications to select and retrieve content directly through the viewer’s user interface, based on interactive actions such as text selection, area selection, or page-level capture. For software developers, this means the viewer acts not only as a rendering surface but also as a controlled extraction layer that exposes selected text, images, or regions. This approach is valuable in review, approval, and data capture scenarios because it reflects explicit user intent, aligns extracted data with what is visibly selected on screen, and avoids reliance on background parsing alone, resulting in more predictable and user-driven content retrieval within applications.

Several WinForms PDF Viewer components allow content extraction, including:

  • DevExpress WinForms PDF Viewer (part of DevExpress WinForms) allows you to extract user-selected text and visual regions directly through the PDF viewer.
  • Telerik UI for WinForms PDF Viewer (part of Telerik UI for WinForms) allows you to capture visually selected PDF content in the viewer, returning text aligned with user interactions.
  • PDFView4NET Windows Forms Edition by PDF4DEV Solutions facilitates extracting text, images, and regions directly from its PDF viewer based on  user selections.
  • Syncfusion WinForms PDF Viewer (part of Syncfusion Essential Studio Enterprise) lets you retrieve user-selected PDF text and areas via the viewer.

DevExpress WinForms 25.2は、アプリケーションを離れずにAIサービスの切り替えや出力の比較を簡単に実現

DevExpress WinForms is a comprehensive suite of 190+ UI controls and development tools designed for building high-performance desktop applications. It offers a broad array of customizable controls, from data grids and ribbon interfaces to advanced charts, maps, and diagramming components. This empowers developers to rapidly create functionally rich applications, while adhering to accessibility guidelines and touch-enabled technology for modern Windows environments.

The DevExpress WinForms 25.2 update introduces multi-provider support in the AI Chat Control, allowing developers to integrate several AI services into one application. This enables advanced use cases such as side-by-side comparison of responses from different AI models, concurrent sessions with independent chat histories, and dynamic switching between providers during runtime. It’s especially useful in environments where evaluating model performance or offering user choice is essential, such as customer support tools, research platforms, or development sandboxes.

ComponentOne Studio WinForms 2025 v2は、FlexPieを横に揃えたラベルで、よりきれいなビジュアルと読みやすさを向上

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

ComponentOne Studio WinForms is licensed per developer on a perpetual basis and includes a 12 month subscription. Priority Support is also available. See our ComponentOne Studio WinForms licensing page for full details.

PyCharm 2025.3は、ローカル開発と同じツールとインターフェースでリモートマシン上でJupyter Notebookの実行とデバッグをサポート

PyCharm by JetBrains is a comprehensive Integrated Development Environment (IDE) specifically designed for Python programming. It offers a range of features to enhance productivity, including code analysis for error detection, a visual debugger for troubleshooting, integrated unit testing for code verification, and support for version control systems to manage code changes. PyCharm also caters to web development using frameworks like Django, making it a powerful tool for both experienced developers and beginners in the Python world.

The PyCharm 2025.3 update enhances remote development by providing full support for Jupyter Notebooks running on remote machines, so developers can work directly where their code and data reside without transferring files locally. It maintains a consistent IDE experience by preserving the same editor intelligence, refactorings, shortcuts, and debugging capabilities available in local notebooks, while rendering interactive outputs such as tables, plots, and widgets directly in the IDE. Developers can also create and manage remote Python environments with the same level of control as local ones, and explore large datasets efficiently using interactive tables or the Data View tool window, reducing friction in data driven and compute intensive workflows.
