You can certainly instantiate other Ops inside your own, as well as hook them
up and evaluate them. Unless I’m mis-remembering, the simplest place to create
and connect them is _validate, but if you’re always going to need the Blur op,
I think you could also create it in your constructor and include its hash in
your op’s in `append`.
Iop* blurOp = dynamic_cast<Iop*>(Iop::create("Blur"));
blurOp->set_input(0, input(0));
Iop::set_input(0, blurOp);

Subject: RE: [Nuke-dev] DD::Image::Blur
Sounds like you want to be in Python mode, and not C++… Gizmo capabilities come
to mind. Jonathan can correct me, but I don’t believe you can hand your
_engine lines to an exernal class. The only answer I’ve found in the past is
to actually do the Gaussian blur yourself, in your C++ code. In fact, my first
reaction would be to do the blur as an integral part of whatever computation
you with to accomplish.
For sure you can’t make an instance of another Iop from within another Iop… it
would wreck havoc with Nuke’s cache management, I’m thinking.

Subject: [Nuke-dev] DD::Image::Blur
In my Iop plugin, I need a (Gaussian) blurred version of the input image, and I
see DD::Image::Blur exists, but how do I use it?
Can I make a instance of it and just ask for a blurred version of the line I am
processing?
It is not used in any of the example plugins.
Thanks.
