The background color does not affect the background numbering of lines of code

[mowshon]

First of all, I want to thank you for a wonderful module! This was what I was looking for and almost began to use Selenium for this.

I want the background of the line numbering to match the background of all the code. But apparently in the code I did not find where to specify the background color for the lines.

from code2image.cls import Code2ImageBackground

c2i = Code2ImageBackground(code_bg='#243036', img_bg='#5b81e3', line_numbers=True, shadow_dt=1)

with open('coding/requests-status-code/code.py') as f:
    code = f.read()

img = c2i.highlight(code)

# save the image
img.show()

Result:

Also, the rectangle border radius is hardcoded and I can't change it from Code2Image attributes?
