toStringz returns an immutable(char)*, so you can assign it to a const(char)*
or an immutable(char)* but not a char*. If you want to assign to a char*, then
you need to use toUTFz, which you are most definitely using incorrectly. The
documentation gives several examples on how to use it correctly, but if what
you want is a char*, then you'd do
this.filename = toUTFz!(char*)("test.bmp");
toUTFZ is a templated function which requires that you give it the type that
you want to convert to. You were trying to call it without giving the type.
