I know there is a way to save a Slide as an SVG, but is there a way to save a SHAPE as an SVG?
I have observed the issue shared by you and regret to share at present the support for converting shape to SVG is unavailable in Aspose.Slides. An issue with ID SLIDESNET-34149 has already been created in our issue tracking system to provide the requested support. This thread has been linked with the issue so that you may be automatically notified once the issue will be resolved.
I also like to add here that Aspose.Slides does allow to create the shape thumbnail in commercially available formats. Please visit this documentation link to serve the purpose in this regard.
We are sorry for your inconvenience,
