jpeg pixel aspect ratio

[Thomas_Do (Thomas)]

@natureboi

unit 0 = pixel aspect ratio (par)

then i extract the xdensity and ydensity values and display them like so:
xdensity 100 par, ydensity 100 par

100 seems wrong, which is why i posted here. i will remove the suffix (par) and either display 100 or 100/100.

In that example the aspect ratio is 100/100=1. No density given. Is that correct for the image in question?
