Antenna House PDF APIを使用すると、開発者はPDF処理機能をアプリケーションやWebサービスに統合可能

Antenna House PDF API is a command-line program enabling developers to integrate PDF processing functionalities into their applications and web services*. It offers features like information retrieval, text extraction, page manipulation, watermarking, and security settings, simplifying tasks like creating searchable archives or password-protecting documents. It also enables advanced PDF processing, such as converting to the international standards PDF/A-1b and 2b for long-term PDF preservation, embedding and integrating fonts, optimizing PDFs, linearization for Web display, and 256-bit AES encryption.

Because the software is run by providing commands and options, information retrieval, processing, and editing of PDF files can be accomplished with minimal development effort. It can also be used with programming languages like PHP, Python, Ruby, and others to call and control executables, making it simple to integrate into web services.

Antenna House PDF API is available in Server, Standalone, and OEM/ASP licenses. Licensed per server/user, and available as perpetual licenses with annual renewable maintenance or annual subscription licenses that must be renewed each year to continue using the software. See our Antenna House PDF API licensing page for full details.

*A separate ASP contract is required if the service is embedded in a Web service and provided to an unspecified number of people.

.NETアプリでのPDFへのポリライン注釈の追加

5月 16, 2024
特定の領域を強調して、要素を視覚的に接続し、PDFドキュメント内のパスをトレースしして、読者のコミュニケーションと明瞭さを向上

Polyline annotations in PDFs are interactive elements that enable the creation of free-form shapes defined by connected straight line segments. This functionality offers a versatile tool for reviewers or editors to precisely highlight specific areas, connect elements visually, or trace paths within the PDF document, promoting better communication and clarity for readers. They are particularly beneficial for creating dynamic and interactive documents as they help in embedding more complex graphical data, which can improve the usability and readability of PDFs in technical fields such as engineering, architecture, and design.

Several .NET PDF components allow you to move, resize, remove or edit the appearance of polylines in PDF files, including:

  • DevExpress PDF Document API (part of DevExpress Office File API) lets you add and manage interactive polylines for highlighting or connecting elements in PDFs.
  • Document Solutions for PDF by MESCIUS offers robust polyline drawing tools to improve visual data representation and document interaction.
  • Aspose.PDF for .NET empowers developers to create and manipulate polyline annotations within PDF documents using C#.
  • Syncfusion WPF PDF (part of Syncfusion Essential Studio Enterprise) allows developers to implement polylines with advanced graphical control within user-friendly interfaces.
