<!-- Greeting --> Hi @sandeepsangoju270! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team. <!-- Answer --> This issue was recently fixed in Superset master: blank images from "Download as image" were caused by Canvas elements (used in pie charts and other visualizations) losing their pixel data during export. The fix (PR #35491) adds logic to preserve Canvas content, so downloaded images now correctly include the chart visualization instead of a blank or black rectangle. Make sure your deployment includes this update—if you’re running a recent master or latest-dev build, it should be present already [(details)](https://github.com/apache/superset/pull/35491). If you’re still seeing blank images: - Ensure the chart is fully rendered before exporting. - Check the browser console for errors during export. - Try exporting other chart types or using a different browser to isolate the issue. - If the problem persists, check for any relevant errors in Superset logs and share them for further diagnosis. Note: The export only captures what’s visible in the DOM, and some chart types or rendering methods may still have limitations [(reference)](https://github.com/apache/superset/issues/33904). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
