Well, itβs not so easy to get it with static maps. You can omit the scaling task and hope that Google chooses what it considers the best.
In any case, this is how I got rid of it. I had my own zoom in / out buttons to display next to the map image. After a click, I increase or decrease the current zoom value and load the map image.
I know this is not very, but he is doing his job.
