Export Mind Map as Image

Export Mind Map as Image

Mind Elixir exports images through the built-in SCST engine from @mind-elixir/export-mindmap. SCST is a lightweight, high-performance DOM-to-image library based on SVG <foreignObject> + Canvas, with zero third-party screenshot dependencies.

1. Installation

Install @mind-elixir/export-mindmap as a dependency.

npm install @mind-elixir/export-mindmap

2. Usage

Use the downloadImage / exportImage functions to capture the mind map nodes and download them.

import { downloadImage, exportImage } from '@mind-elixir/export-mindmap'
// Assuming `mind` is your MindElixir instance

// Download as PNG / JPEG / WEBP
await downloadImage(mind, 'png') // format: 'png' | 'jpeg' | 'webp'

// Or get the URL for preview / custom handling instead of downloading
const url = await exportImage(mind, 'png')

3. Using SCST directly

SCST is also exported from the package and can be used to screenshot any DOM element.

import { domToBlob, domToDataURL, domToObjectURL } from '@mind-elixir/export-mindmap'

const blob = await domToBlob(element, 'png', options)
const dataUrl = await domToDataURL(element, 'jpeg', options)
const objectUrl = await domToObjectURL(element, 'webp', options) // most memory-efficient for downloads

Note: The built-in mind.exportSvg() method is deprecated. Please use the method above for new projects.
