Thread: SDL_TTF - Memory leak when drawing text

    [Solved] SDL_TTF - Memory leak when drawing text

    Hey guys.

    I am currently playing around with SDL and am having a memory leak when rendering some text. I have found out that the code causing the memory leak is the one below. The code is simplified.

    Code:
    For I:= 0 To High(FElements) Do
      begin
        Color.r:= 255;  Color.g:= 0; Color.b:= 0; // Color is of type TSDL_COLOR.
        Tmp:= TTF_RenderText_Blended(FElements[I].Font, 'Some text', Color); // Tmp is a pSDL_SURFACE.
        SDL_BLITSURFACE(Tmp, NIL, Screen, Rect); // Rect is a pSDL_RECT.
      end;
    The problem is that although I know the leak is there (I suspect it is the pSDL_SURFACE), I don't know how to fix it. Any help would be appreciated.

    Thanks!

    Quite simply, you need to either store the surface somewhere and reuse it, or call SDL_FreeSurface() as soon as you're done with blitting.
