# jiffy A TikZ-based page-layout diagnostic tool for LaTeX. **Version:** 0.3 (2026/09/13) **Author:** Scot Parker **Contributors:** Gemini Pro and ChatGPT **License:** LaTeX Project Public License (LPPL) version 1.3c ## Description The `jiffy` package produces scaled graphical diagnostics of a document's page geometry. In two-sided mode, `\jiffy` generates a verso diagram, a recto diagram, and a consolidated data sheet. In one-sided mode, it generates one geometry diagram and a data sheet. The data sheet contains page dimensions, off-page diagnostics, and document/typography information. The package supports a miniature renderer and a true 1:1 full-page overlay. Display strings are provided for English (US), Vietnamese, Spanish, German, French, and Dutch. ## Installation Install `jiffy` through your TeX distribution once it is available from CTAN, or place `jiffy.sty` in the same directory as the document for local testing. ## Usage ```latex \usepackage[ pt_precision=1, fullpage=false, display-language=english-us ]{jiffy} \begin{document} \jiffy \end{document}
