Pdfium
Pdfium is an open-source PDF rendering engine developed by Google, based on the PDFium library from Foxit Software. It provides high-performance rendering and manipulation of PDF documents, including text extraction, annotation support, and page rendering. It is widely used in applications that require embedded PDF viewing or processing capabilities, such as web browsers and document management systems.
Developers should learn Pdfium when building applications that need to display, edit, or process PDF files without relying on external software like Adobe Reader. It is particularly useful for web browsers (e.g., Chrome), mobile apps, and desktop tools that require fast, reliable PDF rendering. Use cases include implementing PDF viewers in software, extracting text or images from PDFs, and adding annotations programmatically.
