Google static maps without url limit [closed]

I wanted to create an image of several routes in google maps, I already used the encodepath to reduce the size of the url, I also tried to reduce the definition of the points of the coordinates among other ideas that I had however what it takes is not to have any impediment of characters. Using the html2canvas may be a solution but because it works only on the client side is an impediment to some functions that you wanted to use. Here is an example image of what I am looking for. The solution may not have to go through using static maps, which I really look for are ideas to help me find a solution to my case. Thanks
