在 Web 應用中將手寫筆記添加到 PDF

11月 26, 2025
帶有自由繪圖和墨蹟注釋的 ASP.NET Core PDF 控制項允許使用者將簽名、草稿和筆記直接添加到文件。

Freehand Draw, also known as Ink Annotation, in ASP.NET Core PDF Viewer controls allows users to add freeform, hand-drawn annotations directly onto PDF documents. This feature mimics natural handwriting or sketching by enabling input through mouse, touch, or stylus, making it especially useful for scenarios requiring personal notes, signatures, or diagrammatic feedback. The annotations are embedded as part of the PDF, ensuring they remain accessible and visible across different platforms and viewers. It is commonly used in applications where document review or digital signing is required, enhancing interactivity and collaboration within PDF-based processes.

Several ASP.NET Core Assembly PDF Viewer components offer support for Freehand Draw/Ink Annotation including:

  • Document Solutions for PDF by MESCIUS allows you to draw free‑hand ink annotations that capture user‑stroke paths and embed them as editable vector markup within a PDF.
  • ImageGear .NET by Accusoft enables freehand and polyline annotation so developers can capture scribbles, arrows or curves and save them as PDF annotation objects.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) supports ink annotation within its viewer, enabling users to draw and add signatures to PDFs.

ABP Platform 10.0 添加 Elsa 工作流程模組，使開發人員能夠直接在其應用中設計、執行和管理視覺化工作流程。

ABP Platform is a comprehensive framework designed to accelerate the development of enterprise software solutions by offering an opinionated architecture built on best practices for .NET and ASP.NET Core. It equips developers with the essential infrastructure, production-ready startup templates, pre-built application modules, and modern UI themes needed to build robust, scalable, and maintainable applications. With powerful tooling, detailed guides, and extensive documentation, ABP Platform improvs implementation, reduces repetitive tasks, and ensures consistency across projects. Ideal for organizations seeking to enhance productivity and maintain high-quality standards, it enables teams to focus on delivering business value while the platform handles architectural complexity and automation.

The ABP Platform 10.0 update introduces the Elsa Workflow module, giving developers a fully integrated way to design and execute visual, event-driven processes within both monolithic and microservice architectures. With built-in support for Elsa Studio, developers can model and manage behavior through a hybrid UI while relying on ABP to handle execution, state management, and service interactions, resulting in a more consistent and maintainable approach to orchestrating application processes.

To see a full list of what's new in version 10.0.0, see our release notes.

The ABP Platform is available as a Team, Business or Enterprise license, which entitles developers to use the platform's Pro features and provides software updates and technical support for 1 year. See our ABP Platform licensing page for full details.

精確跟蹤網路路徑

.NET 元件中對 TraceRoute 的支援有助於開發人員診斷延遲、對應封包路由，以及最佳化網路應用程式中的效能。

TraceRoute is a network diagnostic protocol used in .NET Communications and Messaging controls to determine the path packets take from the source to a destination across an IP network. It works by sending packets with incrementally increasing Time-To-Live (TTL) values, which prompts routers along the path to return error messages that help identify each hop and measure transit delays. This functionality is particularly useful for monitoring network latency, diagnosing connectivity issues, and understanding the routing behavior of networks in distributed systems. By integrating TraceRoute into a .NET application, developers gain visibility into network paths, enabling more informed troubleshooting and performance optimization of communication processes.

Several .NET Comms & Messaging components offer support for TraceRoute protocol including:

  • IPWorks .NET Edition by /n software lets you perform a TraceRoute to map network hops to a designated host and analyze latency across each segment.
  • PowerTCP Sockets for .NET by Dart Communications supports an asynchronous TraceRoute feature to identify packet‑routing paths and measure round‑trip delays.
  • SocketTools .NET Edition by Catalyst Development Corp. allows a TraceRoute operation by sending timed‑echo packets with incremental hop limits to detect intermediate routers.

ActiveReports.NET v19.2 添加用於 Web 檢視器 PDF 匯出的權限設定面板，從而能夠精細控制使用者互動。

ActiveReports.NET from MESCIUS, is a comprehensive reporting solution for developers building applications in .NET. It helps you to design and deliver visually appealing reports through user-friendly designers and a wide range of controls. ActiveReports simplifies report creation and distribution with a versatile API, rich data source connectivity, and support for multiple export formats. This translates to increased developer productivity and improved end-user experience with powerful reporting functionalities within your .NET applications.

The ActiveReports.NET v19.2 update introduces configurable permissions for PDFs exported from Web Viewers, allowing developers to apply precise controls over how end users interact with generated documents. By enabling encryption and selecting permissions such as copying, printing, annotating, modifying, filling forms, and accessing content through assistive readers, developers can enforce security, compliance, and workflow requirements directly within the export process. This update optimizes permission management across the JS Viewer, Blazor Viewer, and ASP.NET WebViewer, providing a consistent and efficient way to govern document behavior without additional code or external tooling.

To see a full list of what's new in v19.2, see our release notes.

ActiveReports.NET is licensed per developer and is available with or without a 12 month support and maintenance subscription. See our ActiveReports.NET licensing page for full details.

用內置驗證工具維護可靠的試算表資料登錄，該工具可防止錯誤並保持共用活頁簿之間的資料完整性。

Data validation in spreadsheets allows users to control what information can be entered into each cell, ensuring that data remains accurate and consistent across a workbook. By defining specific rules and restrictions, it helps prevent incorrect inputs and maintains the integrity of shared data. Users can provide guidance through prompts or drop-down lists, reducing the likelihood of errors and saving time on data correction. This feature is especially valuable in collaborative settings, such as managing budgets, tracking inventory, or collecting survey responses, where reliable data entry is essential for accurate analysis and reporting.

Several ASP .NET Core spreadsheet products offer data validation, including:

  • DevExpress ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) lets you control data accuracy by defining validation rules and guiding users with clear feedback.
  • Aspose.Cells for .NET allows you to enforce consistent data entry by applying validation rules, dropdown lists, and custom error alerts.
  • Telerik ASP.NET Core Spreadsheet (part of DevExpress ASP.NET and Blazor) validates inputs, preventing errors, and maintaining consistent information across workbooks.
  • Syncfusion ASP.NET Core Spreadsheet (part of Syncfusion Essential Studio Spreadsheet Editor SDK) enables data entry through automatic prevention of invalid values.
