@priya4075 This service delegates a fair amount of the work out to other services, specifically the rsvg-convert, convert, and pngcrush. The tests are complaining that it cannot find those executables.

I am not sure if those tools are available in Windows, or what is involved in getting python to be able to see them (possibly adding them to the PATH).

Unfortunately I only have experience with, and this software is only tested with linux systems, so there are no guarantees that it will work on Windows, but we welcome pull requests if there are things that need to be changed to make it work on different platforms, as long as it doesn't break functionality on linux systems.

This error only i am getting. I am passing this mathml.

$\underset{n\to \infty }{\lim }\hspace{0.17em}\ln \left(\frac{12n+2}{-9+4n}\right)=\ln 3$

I am trying in Windows 7 OS. Flask server is getting initiated. Just Help me to get an output properly.

@priya4075 This seems to be an error returned directly from svgtex.

That means that everything is probably set up and running well on the mathml-to-image-service side.

To confirm, you can try accessing svgtex directly (by default localhost:16000), type your mathml in there, and see the result that you get.

If you get the same result, then it's an issue with svgtex not understanding the mathml that you've sent it. If not, then it's possibly an issue with the way that mathml-to-image-service is sending the mathml to svgtex, and we can look into that.

Also, maybe try the mathml presented in the docs: http://mathml-to-image-service.readthedocs.io/en/latest/getting_started.html#using-the-api , and see if that works.
