What is the D version of `createSizeIntWH`? In C++ it
returns a pointer but in D version it returns an instance.
extern(C++){
cv.Size_!int createSizeInt();
cv.Size_!int createSizeIntWH(int w, int h);
void deleteSizeInt(ref cv.Size_!int sz);
}
createSizeIntWH returns a pointer to instance, not an
instance. Try:
cv.Size_!int* createSizeIntWH(int w, int h);
I doubt it because in
https://dlang.org/spec/cpp_interface.html#using_cpp_classes_from_d
cpp code:
Derived *createInstance(int i)
d code:
extern (C++){
...
Derived createInstance(int i);
}
I wouldn't use a class on the D side, unless your C++ type uses
virtual functions. Classes in D are different from structs, it is
not the same as C++ where they are basically the same thing.
