Question 1

How does PDF-Writer compare to libharu for generating PDFs in C++?

Accepted Answer

PDF-Writer offers more comprehensive features like PDF parsing, manipulation, and encryption support, while libharu is simpler but may be sufficient for basic generation. PDF-Writer's performance and modular dependencies make it better for complex workflows, but it has a steeper learning curve.

Question 2

How to build PDF-Writer on Linux without OpenSSL?

Accepted Answer

Use the CMake option -DPDFHUMMUS_NO_OPENSSL=TRUE to exclude encryption support. Run 'cmake ..' with this flag in your build directory, then compile with 'cmake --build . --config Release'. This disables PDF 2.0 encryption but simplifies dependency management.

Question 3

Does PDF-Writer support creating PDFs from HTML or web content?

Accepted Answer

No, PDF-Writer is a low-level library focused on programmatic PDF generation and manipulation, not HTML rendering. You would need to convert HTML to PDF using other tools first, then use PDF-Writer for further processing.

Question 4

What are the image format limitations in PDF-Writer?

Accepted Answer

It supports JPEG, PNG, and TIFF via bundled libraries, but options like PDFHUMMUS_NO_TIFF allow exclusion of formats. Ensure system libraries are available if not using bundled ones, and note that advanced image features may require additional configuration.

Question 5

Can I use PDF-Writer in a Node.js project?

Accepted Answer

Yes, via the MuhammaraJS wrapper mentioned in the README, but this adds a layer of abstraction and may introduce performance overhead. For native C++ integration, you'd need to build and link the library directly.

Question 6

How to handle PDF forms with PDF-Writer?

Accepted Answer

PDF-Writer provides low-level manipulation capabilities, so form handling requires custom code to modify PDF structure. It lacks built-in high-level APIs for form creation or filling, unlike some commercial libraries.

Question 7

Is PDF-Writer suitable for high-volume PDF generation in server applications?

Accepted Answer

Yes, its high-performance C++ core and optimization make it ideal for server-side use, but ensure proper resource management and consider the setup overhead for dependencies like OpenSSL in production environments.
