gitX Mermaid Exporter

Export Mermaid diagrams exactly as rendered by GitHub Viewscreen.

Export Mermaid diagrams from GitHub Markdown pages without rerunning Mermaid or changing their layout. gitX Mermaid Exporter reads the SVG already rendered by GitHub Viewscreen, preserving the current node positions, edges, text, colors, viewBox, and light or dark theme. Export one diagram from its upper-left controls, or use the extension toolbar to choose multiple diagrams and formats before downloading. Features: Export the current GitHub-rendered diagram as native SVG. Export an adaptively cropped PNG using Auto or a manual 1x-6x scale. Select individual diagrams and formats for a batch export. Handle multiple diagrams, delayed rendering, SPA navigation, iframe reloads, and theme changes. Generate safe filenames from the repository, Markdown filename, and diagram index. Work with public and private GitHub repositories through the user's existing browser session. All processing stays in the browser. The extension does not upload Markdown, SVG, PNG, repository content, or usage data. It contains no telemetry, analytics, advertising, account system, remote service, CDN, or remote code. This is an independent extension and is not affiliated with or endorsed by GitHub or the Mermaid project.
