How to set a transparent mask from sf::Sprite? (not from sf::Image)

[joaojoaojoao]

Hi

(This is my first post on SFML, so please..be gentle  )

I have a class that contains:

   sf::Texture   mTexture;
   sf::Sprite     mSprite;


I need to create an image with some part that is invisible.
I've read that there is a method called "createMaskFromColor()"

But this method is only used for sf::Image's.

Since I don't have any image on my class (only a texture and a sprite), how can I set a transparent mask from a sprite?

Thank you!

Loading a texture is effectively a short way of loading an image and then transferring that to a texture so, if you do that manually, you can manipulate the image before it gets to the texture.

sf::Image image;
image.loadFromFile("image.png");
// manipulate image here
sf::Texture texture;
texture.loadFromImage(image);
sf::Sprite(texture);

The image (but not the texture) can be discarded after the texture has loaded from it so the image manipulation can happen inside a function with local scope.
