API for plotting picture(sketch) which was captured from camera

Hi, there. I am curious about if the line-us could plotting the sketch of people’s faces which I captured from a camera or iPad. If not, or is it possible for me to import a sketch of faces to some software such as Inkscape and use the corresponding extension to plotting. I am capable of doing the conversion between faces to sketch/lines.
Thanks for your response, My English writing was not that good. sorry.

Hey, I want to implement the API to my dishwasher blog where the technician may be contacted through the app. I don’t know if it is possible or not but we do have only two options due to certain limitations. One is Viber and the other is line. I am looking for someone who could do it on my behalf for our business.
