アクセシブルなPDFのためのファイルサイズ最適化

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.

PDF4NET 14 adds support for PDF structure compression when saving PDF/UA files. Portable Document Format/Universal Accessibility (ISO 14289) is an international standard that addresses accessibility concerns in Portable Document Format (PDF) files. It ensures that PDFs can be readily understood and utilized by individuals with disabilities who rely on assistive technologies like screen readers. Compressing the structure leads to smaller file sizes, boosting upload and download speeds, and reducing required disk space.
