PDF Processing Guide

Mandatory: LaTeX-First Workflow

[!IMPORTANT] ALL new PDF generation MUST follow a LaTeX-first workflow. Directly creating structured documents using libraries like reportlab or fpdf is discouraged for new content. This ensures maximum structural integrity, professional typography, and consistent styling for both scientific articles and premium educational materials.

The Standard Workflow

1. Draft LaTeX Source: Generate a valid .tex file with the desired content and layout.
2. Compile to PDF: Use a LaTeX engine (e.g., tectonic or pdflatex) to synthesize the final document.

Example: Python LaTeX Orchestration

import subprocess

def create_pdf_from_latex(tex_content, output_name="document.tex"):
    # 1. Write the LaTeX source
    with open(output_name, "w") as f:
        f.write(tex_content)
