Export Feature: How do i export OSM File + PNG Map?

Hi there,

I started developing a tool in Unity to display Buildings and Roads created from the OSM File data you get from the Export Feature of this site. However i now have the problem to export the exact bounds of my chosen area as an underground PNG. Since i have to drag the area to export similar to the area i export as an OSM File, it never fits 100% correct.

My question, is there a possibilty to export both, an OSM File with the exact corresponding Map as PNG?

(Sorry about language, english is not my native one)
