Author Topic: String sub rectangle (Read 6538 times)

Hi!

I was using SDL for a long time and I used SDL_TTF. Later, I installed SFML and I was very happy about it. I like it a lot and it is much more simpler and strings are better than with SDL_TTF by far. However, there's one thing I can't do with SFML that I could with SDL_TTF, because it was a big texture rather than small letters textures. I can't take my string and cut it where I want just to have a part of a letter and the rest of the string or any other sub rectangle.

I think it would be nice to have a function that takes the sub rectangle coordinates and draw a sub part of the string or that return a sf::sprite that I could then sub-rect myself without any problem.

I may have forgot a function that could do that, but I looked for a while in the documentation, and I couldn't find anything. So, what do you think of my idea? I won't care if it's a bad suggestion.

Render to image will (is?) be implemented in SFML 2, I believe that's what you want.

Well, if we'll be able to do that in SFML2, then there isn't any problem.

However, I believe that the first solution (directly drawing the sub rectangle from the string) would be lighter, easier to add, and simpler to use.

Thanks for the answer!

sf::String will be rewritten in SFML 2. Plus, clipping masks may also be added soon. So don't worry, you just have to wait

Will those masks be added to SFML2, too?

If I can come up with a robust and clean public API, hopefully yes

Hi,

thank you very much for the answer! I'm happy that SFML 2 will handle this and I'll be waiting for it.

Will that clipping mask be only available for sf::String or other sf::Drawables aswell? (sf::Sprite already has SetSubRect(); don't know if a clipping mask is wanted for other sf::Drawables).
If so, I'd suggest sf::String::SetClipMask( const sf::IntRect & ).

(well, the main reason why I'm writing this is to bump the thread; a feature like this is hardly needed at my side

)

Yes, it would be a generic feature that would apply to everything that is rendered.

Okay, so I guess it'll take some time to get implemented. Anyway, thanks for the reply.
