Could you build this?
Partial Generating basic PDFs with Java libraries can be assisted by LLMs, but building a robust declarative layout engine with complex paging, flow-breaking, and table rendering is a heavy algorithm design task.
What it would actually take: A custom declarative PDF engine requires implementing a box-model layout system, flow breaking across page boundaries, font measurement, and SVG/vector compilation in Java over low-level libraries like PDFBox or OpenPDF. The critical difficulty is handling nested dynamic tables, flexible wrapping, and absolute positioning constraints deterministically across multi-page boundaries. It demands strong computer science foundations in layout tree algorithms, constraint solving, and typographical metrics.
