Great measurement tool
Have to say this is a great tool to have. For a long time I’ve had to use a screenshot in order to get measurements, which worked fine. Only issue I’m finding is that Euclid gets the incorrect measurement when used on Retina screens. For example, Euclid will get a measurement of 440px whereas taking a screenshot would get about 220px. Not sure if this is intentional since I know if I took a screenshot of that 220px area, it would actually turn out to be a 440px image on a normal screen.
