Constructor & Destructor Documentation

CartoType::TPointFixedSmall::TPointFixedSmall	(	const TPoint &	aPoint,
		int32	aFractionalBits
	)		[inline]

Construct a TPointFixedSmall from a point with 0...27 fractional bits.

Member Function Documentation

CT_EXPORT void TPointFixedSmall::HyperbolicRotate

(

TFixedSmall

aZ

)

Perform hyperbolic rotation according to the specified angle. If the original vector is the unit vector (1,0) the result is iX = cosh (aAngle) and iY = sinh (aAngle).

void CartoType::TPointFixedSmall::operator+=

(

const TPointFixedSmall &

aPoint

)

[inline]

Offset a point by another point, treated as a positive vector.

void CartoType::TPointFixedSmall::operator-=

(

const TPointFixedSmall &

aPoint

)

[inline]

Offset a point by another point, treated as a negative vector.

CT_EXPORT void TPointFixedSmall::Rotate

(

TFixedSmall

aAngle

)

Rotate the vector according to the specified angle. If the original vector is the unit vector (1,0) the result is iX = cos (aAngle) and iY = sin (aAngle).
