# PDF documents Produce PDF deliverables with two libraries: **fpdf2** to generate new documents and **pypdf** to manipulate existing ones (merge, split, rotate, fill forms). Follow every section below before declaring a PDF done. ## Installing the libraries Install each pinned dependency with its own `exec` call — commands have a bounded wall clock, and one `pip` invocation per package stays inside it: ``` python3 -m pip install --user fpdf2==2.8.3 python3 -m pip install --user pypdf==6.16.1 ``` Installs work only when this chat's network policy allows package managers, and they persist for the rest of the conversation. If an install is refused by policy, do not retry: tell the user to enable the package-manager network policy for this chat, and offer the closest format you can produce without the library (for example markdown or HTML) — only with their knowledge, never as a silent substitution. If a dependency cannot be installed at all, say so plainly instead of quietly delivering a lesser format. ## Generating PDFs with fpdf2 - Build documents from `fpdf.FPDF`: `add_page()`, `set_font(...)`, then `cell(...)` / `multi_cell(...)` for text and `image(...)` for figures. - The core fonts (Helvetica, Times, Courier) cover ASCII reliably. For text beyond Latin-1, register a Unicode TrueType font with `add_font(...)` before use; never let glyphs silently render as placeholders. - Set metadata that helps the user: `set_title(...)`, `set_author(...)` when the documen
