GetAngle()

Degree100 GetAngle

(

const Point &

rPnt

)

The Y axis points down! The function negates the Y axis, when calculating the angle, such that GetAngle(Point(0,-1))=90 deg.

GetAngle(Point(0,0)) returns 0.

Returns

the returned value is in the range of -180.00..179.99 deg and is in 1/100 deg units
