Yes, I agree that "it depends on user settings", but my question still holds, i.e. what is the default? If I just rotate or zoom, what interpolation method is adopted? Analogously, where can I find those "user settings"? The practical use lies in the fact that I want to write the...

Ok, I'll try to be more precise. I want to test the Euclidean Invariance of a filter that I have designed. To do so, I want to compute the numerical difference between a) a transformation F (that could be for instance a zoom or a rotation) and then the filter b) the filter and then the transformatio...

What exactly do you mean when you say that "vector objects are described as connected points"? Let us suppose that I have a generic RGB picture (a painting, for instance). I open it with Inkscape and I do a 3x zoom of a small square inside that. An interpolation method has to used to get t...

Does anyone know what interpolation method is used by default for the following operation?
i) rotation
ii) zoom

I've tried to look for this info on the Internet, but so far I have no idea of the answer...
