Firstly, your chosen library should support a wide array of PDF versions (e.g., PDF 1.4, PDF 1.7, etc.). Libraries that rely on a single underlying engine might struggle with less common versions or corrupted files. Consider libraries offering features like automatic format detection, which can identify the PDF version and apply appropriate parsing strategies. Secondly, efficient error handling is critical. Not all PDFs are perfectly formed; some might be damaged, truncated, or contain invalid elements. A good library will gracefully handle these scenarios, perhaps by providing informative error messages or skipping over problematic sections instead of crashing. It's crucial to implement error handling within your application as well, so that even if the library encounters an error, the user experience isn't completely disrupted. Thirdly, security is paramount, particularly when dealing with PDFs from untrusted sources. The library should be resilient to attacks that might exploit vulnerabilities in its PDF handling. Look for libraries that adhere to security best practices, and carefully review any permissions it requests. Finally, consider performance optimization. Some PDF files can be quite large and complex. A well-designed library will employ optimization techniques to ensure smooth and responsive rendering, avoiding excessive memory usage or lagging. Test your application thoroughly with diverse PDF samples of different sizes, formats, and levels of complexity to ensure smooth functionality across the board. Remember to thoroughly research libraries such as Apache PDFBox or iTextG, evaluating their feature sets, community support, and licensing terms before integration.
