EllipseRadialLength function

In unit GraphMath

EllipseRadialLength - Radial-Length of non-rotated ellipse at any given Eccentric Angle.

Declaration

pascal

function EllipseRadialLength(const Rect: TRect; 
 EccentricAngle: Extended): LongInt

Description

Use EllipseRadialLength to get the Radial-Length of non-rotated ellipse at any given Eccentric( aka Radial ) Angle. It is primarily for use in other routines such as RadialPoint. The Eccentric angle is in 1/16th of a degree. For example, a full circle equals 5760 (16*360). Zero degrees is at the 3 o'clock position.
