PDF4NET 15は、アラビア語、ベンガル語、デーバナーガリー語、ヘブライ語、クメール語、タミル語、タイ語などの複雑なスクリプトをサポートし、グローバルリーチを拡大

PDF4NET is a .NET library for generating, importing, and manipulating PDF documents on the fly from any .NET application. It does not rely on any Adobe products for creating or importing PDF files. PDF4NET hides the complex structure of PDF files behind a simple object model that allows creation of complex PDF files with a few lines of code.

The PDF4NET 15.0.0 update enhances document processing by introducing support for complex scripts, including Arabic, Bengali, Devanagari, Hebrew, Khmer, Tamil, and Thai. This improvement ensures accurate text rendering, proper character shaping, and right-to-left script support, allowing developers to generate and manipulate PDFs with multilingual content more effectively. By enabling seamless integration of these scripts, the update enhances localization capabilities, improves accessibility, and ensures compliance with diverse linguistic requirements, making it easier to create globally compatible PDF documents without additional customization or external dependencies.

To see a full list of what's new in version 15, see our release notes.

PDF4NET is licensed per developer. All licenses include a 12 month subscription which provides all major and minor product updates and technical support. See our PDF4NET licensing page for full details.

PDF4NET is available individually or as part of PDFBundle4NET.

Bookmark navigation in a PDF viewer enhances the user experience by allowing quick access to specific sections within a document.
