This is strange, since the result of the method is converted to an SDL-compatible type https://github.com/SerafimArts/ffi-sdl-ttf/blob/master/src/Marshaller.php#L83

I can not solve the problem right away, I'll try to figure it out a little later. Thank you very much for the example code to reproduce the error.

[SerafimArts]

Ah, I think I understand! In return expressions i'll should do $this->sdl->cast() instead of $this->cast(). Whoops)

[he426100]

Solved, thank you very much!

[SerafimArts]

Hmm... it seems this still needs to be fixed by the library so that all return types are compatible with SDL (instead of TTF). Is not it so?

[he426100]

I'm sorry, I don't understand these, just modify as you said, the problem solved

[SerafimArts]

Kk. I will re-open the issue so as not to lose it and correct this behavior on the part of the TTF library in next minor patch.
