In this example the pID2D1Factory is a void*, so it will need a
cast to the proper type with a cast(ID2D1Factory) soemtime
after the create call;
Since this particular API takes an out void* (since it is
capable of creating multiple unrelated types), it would need to
look something like this:
HRESULT hr = D2D1CreateFactory(
D2D1_FACTORY_TYPE.SINGLE_THREADED,
pIID_ID2D1Factory,
pfactoryOptions,
pID2D1Factory);
if (SUCCEEDED(hr))
{
assert(pID2D1Factory !is null);
ID2D1Factory factory = cast(ID2D1Factory)pID2D1Factory;
factory.GetDesktopDpi(dpiX, dpiY);
}
I've been super busy at work so haven't had much time to
respond to this thread.
Technically the API's fourth argument could be rewritten to be
an 'out IUnknown', but then you are stuck calling
QueryInterface, and back to having the exact same problem with
the QueryInterface method.
Thanks a lot! That solved my issue.
