RadialPoint function

In unit GraphMath

Get the RadialPoint at any given Eccentric angle on any non- rotated ellipse.

Declaration

pascal

function RadialPoint(EccentricAngle: Extended; const Rect: TRect)
: TPoint

Description

Use RadialPoint to get the Radial-Point at any given Eccentric(aka Radial) angle on any non-rotated ellipse. It is primarily for use in Angles2Coords. The EccentricAngle 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.
