The OneNote API supports getting InkML in beta: https://developer.microsoft.com/en-us/office/blogs/onenote-ink-beta-apis/

The you can use InkMLJs to render it to a canvas: https://github.com/Microsoft/InkMLjs

Once you have it in a canvas, you can export to an image How To Save Canvas As An Image With canvas.toDataURL()?

As for the “extracting text” part… OneNote API does not support getting the ink analysis text from the OneNote page, so you'd have to run the analysis yourself via the coordinates in the InkML.
