Okay but raster images can’t represent circles either, since they’re just approximations using squares
And many “circles” aren’t circles either, but 2D torus approximations. The edge of a true circle is made of infinitesimally small points so would be invisible when drawn. And even if you consider a filled circle, how could you be sure you aren’t looking at a 1-torus with an infinitessimally small hole? Or an approximation of all the set of all points within a circle?
Clearly, circles are a scam.
A 1-torus is a circle, you mean an annulus. You do NOT want to make this mistake at a topologist dinner party, trust me.
Damn, so what’s the name of the shape that’s a flat donut with an inner and outer circular perimeters? i.e. a filled circle with another smaller radius circular area subtracted from it. Or 2D cross section of a torus seen perpendicularly to the plane that intersects the widest part of the torus. A squished donut, or chubby circle, if you like.
Annulus
Damn you PDF, damn you to heck!

Well I’d argue vector image can represent a real circle but what’s on the screen will never be one.
Also why is this on Lemmy Linux?
Titles like this annoy me. If you have something interesting to say - which is the case here - say what it is. No need to obfuscate the topic. It wastes time for everyone.
Anyway, it’s kinda hilarious that the only way to make a proper circle in PDFs is with line caps. What a bizarre format. I hope it’s succeeded by something better sooner rather than later, I can’t think of any time they haven’t been a pain to work with.
I’ve been saying this for years! If properties of a shape cannot be expressed with finite precision then how can that shape exist in a universe with clunky restrictions like the planck length?
