Export Mind Map as Image

Mind Elixir recommends using @zumer/snapdom for high-quality image exports. This tool allows you to convert the SVG nodes directly into image formats.

1. Installation

Install @zumer/snapdom as a dependency.

npm install @zumer/snapdom

2. Usage

Use the snapdom function to capture the mind map nodes and download them.

import { snapdom } from '@zumer/snapdom'
// Assuming `mind` is your MindElixir instance

const downloadImage = async () => {
  // 1. Capture the nodes
  const result = await snapdom(mind.nodes)

  // 2. Download as JPG or PNG
  await result.download({
    format: 'jpg', // or 'png'
    filename: 'mind-map-export',
  })
}

3. Creating a Trigger

You can add a button to your UI to trigger this function.

<button id="export-btn">Export Image</button>

<script>
  document.getElementById('export-btn').addEventListener('click', downloadImage)
</script>

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