自由文字註釋可讓開發人員將持久性文字嵌入到 PDF 頁面中,非常適合審核、審查或協作文件。

Free text annotations in PDF-processing components enable users to place editable text directly onto document pages, enhancing notes, comments, or briefing elements without relying on external tools. This feature supports adding visible text blocks (rather than hidden pop-ups) that remain part of the document's content layer, allowing for richer, in-context feedback and markup across workflows such as review, auditing, or collaborative editing.

Several ASP.NET Core PDF controls offer support for free text annotations including:

  • Telerik UI PDF for ASP.NET Core (part of Telerik UI for ASP.NET Core) lets developers add customizable free text annotations to PDFs, with control over font, position, and more.
  • Document Solutions for PDF by MESCIUS provides a FreeTextAnnotation class that enables developers to place persistent text directly into a PDF, with properties for customization.
  • ImageGear for .NET by Accusoft supports FreeText via its ART marks API, allowing the creation of text annotations on PDFs and exporting them as FreeText annotation objects.
  • Syncfusion ASP.NET Core PDF (part of Syncfusion Essential Studio Enterprise) allows developers to add free text annotations to PDFs with several customization options.

Aspose.GIS for Python via .NET 為開發人員提供了讀取、寫入、分析和渲染 GIS 資料的工具,無需依賴重量級 GIS 軟體。

Aspose.GIS for Python via .NET is a comprehensive geospatial library designed for the Python ecosystem but built on .NET core, enabling cross-platform support across Windows, macOS and Linux environments. It allows developers to read, write, convert, and process a wide range of GIS (Geographic Information Systems) formats, such as Shapefile, GeoJSON, KML, GML, FileGDB, GPX, while also supporting spatial reference systems, geometry creation and analysis, and map rendering into vector or raster outputs (e.g., SVG, PNG). The API emulates a Python-friendly syntax while exposing deep native capabilities of the .NET library, giving users a unified and efficient workflow for geospatial data manipulation.

The library offers significant benefits for organizations and developers working with spatial or location-based data. Because it supports a wide array of GIS formats and allows for conversions between them, it simplifies cross-system data flows, enabling workflows like ingesting an ESRI FileGDB dataset, converting to GeoJSON for web delivery, and then rendering a map image for export. Built-in rendering and geometry operations (such as intersect, union, centroid) enable advanced spatial analytics and map-based reporting without relying on heavy external GIS tools. This makes the product ideal for use cases including mapping applications, location-based services, geospatial data pipelines, and enterprise reporting systems where integration, conversion, and automation of GIS data are required.

Aspose.GIS for Python via .NET is offered as Developer Small Business, Developer OEM, Developer SDK, Site Small Business, Site OEM and Site SDK licenses catering to a range of business needs. Licenses are perpetual, and include 1 year of support and maintenance. Subscription renewals are also available. See our Aspose.GIS for Python via .NET licensing page for full details.

Aspose.GIS for Python via .NET is available individually or as part of the following products:

用直觀的分組和篩選工具輕鬆組織、流覽和分析資料,這些工具可在試算表中創建可折疊的大綱。

Grouping and filtering are key spreadsheet tools that make data easier to manage and analyze. Grouping combines related rows or columns into collapsible sections for clearer summaries. Filtering displays only the information that meets specific conditions, helping focus on what matters most. Together, these features improve data management, reduce visual clutter, and enhance analytical clarity.

Several .NET WinForms spreadsheet controls contain data filtering and grouping controls including:

  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) lets you efficiently organize and analyze large datasets by grouping and filtering data.
  • Spread.NET WinForms (part of Spread.NET by MESCIUS) allows you to manage complex spreadsheets with intuitive grouping and advanced filtering for focused data analysis.
  • Infragistics WinForms Spreadsheet (part of Infragistics Ultimate UI for Windows Forms) facilitates data exploration through grouping and precise filtering.
  • MindFusion.Spreadsheet for WinForms enables streamlined data management with collapsible grouping and targeted filtering to simplify data review.
