chalk-annotate – Chalk-textured annotations for Beamer presentations

This package provides pre-rendered PNG overlays with natural chalk grain and opacity variation for emphasizing text and other content in Beamer slides. It offers six annotation styles: ellipse, underline, box with fill and border, arrow, and strikethrough. Each style is available in five colors: red, blue, green, orange, and purple. The resulting annotations look more realistic than pure TikZ decorations. The package works with XeLaTeX and LuaLaTeX.
