markmap-export 0.1.1

Export Markmap mind maps to high-resolution PNG images

markmap-export

Export Markmap mind maps to high-resolution PNG images.

Why?

Markmap uses SVG with <foreignObject> for KaTeX and syntax highlighting, which breaks standard screenshot tools and SVG converters. This tool uses Playwright to render the actual browser output at any resolution.

Install

uv tool install markmap-export
markmap-export --install-browser

Usage

# Auto-detect optimal size (recommended)
markmap-export mindmap.html

# Specify output path
markmap-export mindmap.html -o output.png

# Custom dimensions and scale
markmap-export mindmap.html -w 3000 -H 4000 -s 2

Options

Option	Description	Default

-H, --height	Viewport height	Auto-detect
-s, --scale	Device scale factor	2.0 (Retina)
