New on CTAN: svg-animate
by CTAN Announcements via ctan-ann 19 Mar '26

Sébastien Gross submitted the svg-animate package. Version number: 1.0 2026-03-16 License type: agpl3 Summary description: Generate animated SVG diagrams with TikZ Announcement text: ---------------------------------------------------------------------- svg-animate is a new LaTeX package for producing step-by-step animated SVG diagrams with TikZ. Animations are implemented as SMIL keyframes embedded in the SVG output, so they run natively in any web browser with no JavaScript and no external dependencies. The animation model is simple: a TikZ picture is divided into discrete steps, and each element is revealed or hidden at specific steps via instantaneous opacity transitions. The same source file produces both an animated SVG (via latex + dvisvgm) and a clean static PDF (via xelatex or lualatex), making it suitable for web publishing and print from a single source. Key features: - \begin{animate} / \reveal / \animstep — minimal, intuitive interface - Per-step durations, looping or one-shot playback - Multi-step and range visibility (step={1,3-5}) - Blinking elements with configurable amplitude (blink=) - Static fallback for PDF output (\noanimate, static key) - Cascading options from global to per-element level Requirements: PGF/TikZ >= 3.1.9, dvisvgm >= 2.9, TeX Live 2022+ or MiKTeX 22+. ---------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/svg-animate More information is at https://www.ctan.org/pkg/svg-animate ------------------------------------------------------------------------ Thanks for the upload.
