Foxit Quick PDF Library does not currently support the extraction of path information. However, the GetContentStreamToString function will extract the content stream which contains all of the drawing commands.
You would need to parse the content stream to extract the paths as well as processing transformations including rotation and scaling.
Here is the contents of a typical stream. The meaning of each function / command can be found in the PDF Specification documents.
