Convert Sprite to Image

[Yukilay]

My question is simple: There is any way to converta Sprite to Image? I would like to compare EACH pixel with Color::Trasparent to approach a better collision management (although I'm sure it isn't worth, I want to be aware of the difference).

Thanks guys.

This would be too inefficient (you would have to retrieve the sprite's texture from video memory). Build your "collision map" (a bidimensionnal array of booleans or alpha values, for example) when you load the texture, and then use it for collision detection.

Maybe you should see this topic on wiki https://github.com/SFML/SFML/wiki/Source%3A-Simple-Collision-Detection-for-SFML-2 which has a functions that compare and the alpha value.
