SuperScript in VSDX text box not working

We have a number of VSDX diagrams we are converting to PNG and SVG that have equations with superscript text in text boxes. Does aspose support superscript text in text boxes, is this fixed in a later version, or is this a bug? We are using Aspose diagram 17.4.


Aspose.Diagram API has support of subscript and superscript text. Kindly send us your source drawing and code. We will investigate your scenario in our environment, and share our findings with you.

How should I send the drawings?


You can compress all files to a ZIP, and then upload to your post. There is an upload button in the header of the post editor. However, if the ZIP size is more than 3MB, then please upload to any free file sharer server, and share its download URL. Your response is awaited.
