Export to image
Would be great to have this either for the end user or even as a developer API. At the moment we're having to rely on some code dating back to 2012 which doesn't work server side on Sharepoint Online..
Thank you for valuable feedback. I’m glad to inform that we have now enabled the functionality to download files as JPEG/PNG images in Visio for the web for the end users. You can choose from the various customization options available in the export dialog.
