Not certain what your example has to do with XDP.

Other than the brushes and what are obviously bitmap effects, my XDP vector work hits a PDF (and EPS) as vector.

If the map had been created with the idea it would be scaled and made properly, then there would not have been an issue. The same goes with any bitmap effects and the brushes in XDP.

Exchange of files between applications is always problematic. I don't know where the map in your example came from. But if it was suppose to be scalable as vector, the client got ripped off and should attempt to get original files from whomever made it.
