static

Compute distance from point px,py to an axis of the band defined.

by pair points (x1,y1),(x2,y2) where lineWidth is the width of the band

Compute the closest distance of approach from point px,py to this line. The distance is computed in pixels units.

Let us call a = distance AM a2=a**2
b = distance BM b2=b**2
c = distance AB c2=c**2
d = distance PM d2=d**2
u = distance AP u2=u**2
v = distance BP v2=v**2 c = u + v
d2 = a2 - u2
d2 = b2 - v2 = b2 -(c-u)**2
==> u = (a2 -b2 +c2)/2c
