I need to draw shapes and save to a file

[Tigre Pablito]

hi people from SFML

I need to draw a black square with a white (with alpha set) circle inside it and then save that to a file. I need this to make a light effect on my Super Mario game. 

I tried with image, circleshape, but wasn't able to find a method that pastes or draws the circle to the image. I know i could do this (without SFML) with window forms and .Net but i'm upset of Sin, Cos, and those.

Can you give me some code example?
Thanks

Draw to a render texture (see tutorial), copy to image (see documentation of sf::Texture), save image to disk.
