SegmentOrientation


Header: FIL.h
Namespace: fil
Module: FoundationLite

Computes the orientation of a segment.

Syntax

C++
C#
 
void fil::SegmentOrientation
(
	const fil::Segment2D& inSegment,
	fil::AngleRange::Type inAngleRange,
	float& outOrientationAngle
)

Parameters

Name Type Default Description
Input value
 inSegment const Segment2D&
Input value
 inAngleRange AngleRange::Type _0_180 Switches between 0-90, 0-180 or 0-360 degrees
Output value
 outOrientationAngle float&

Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when an empty segment is given on input.

Examples

SegmentOrientation performed on a segment with parameters: X1 = 50, Y1 = 50, X2 = 300, Y2 = 300 and inAngleRange set to _0_180.
outOrientationAngle returns 45.
