DCGAN Tutorial - Where is the output image size of the generator set?

I’m still getting started with pytorch, and I don’t understand where the output image size of the generator in the C++ tutorial is set.

I get it to work, but I don’t understand why the Net produces a 28x28 px output (as it is supposed to do).

I found the answer myself, keeping it here for documentary purposes…
