smooth photon propagator

[zhyiyu]

Hi, I really appreciate tikz-feynman package and your work. I would like to ask for an enhancement that, the photon propagator could be more smooth.

As I can see while it is magnified, the photon propagator is actually patched up with straight lines, which would be much more better if it is just the smooth sine function!

If there is anything I could do, please let know and I would really love to be able to help and make tikz-feynman better!

Hi @JP-Ellis and @zhyiyu ,

I see the same problem: The photon and boson propagators look pretty jagged.

I could imagine one could try to increase the number of samples, maybe somewhere around complete sines decoration style definition? I'm not an expert, but maybe one could try something along the lines:

      /tikz/decoration={
        complete sines,
        amplitude=1mm,
        segment length=2mm,
        samples=200 % <----- try to add this
      },

Best regards,
Alex

Thank you for your reply! Can we manually increase sampling points while drawing the diagram?

Hi @zhyiyu ,

Can we manually increase sampling points while drawing the diagram?

Naively I had guessed that this should be possible. However, I had no luck so far. I've tried to add samples=500 to the various draw commands, but with no effect:

-- [boson, samples=500] --

Do you or @JP-Ellis have an idea?

I could not find where the packages are installed on my mac, but I would consider modifying the .sty file.
