How to get a set of point coordinates from a vector editor?

Question

Mathematics

We need a vector editor that could represent a picture in the form of combined sets of coordinates, in mathematical form, that is, without using a special language (svg).
Point coordinates are needed for processing in a mathematical program.
To put it simply, we need a convenient way to quickly draw a picture and translate it into a set of coordinates.

Answer 1

SVG is an easy to parse format, just convert all objects to path before saving.

Answer 2

There is another option to use macros, which are supported by many editors. But, I think that dealing with the document object model and the macro language is somewhat longer than with some text format like svg.
