Detailed Description

A point class containing two fixed-point numbers; see also TPointFixedSmall.

Constructor & Destructor Documentation

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

Construct a TPointFixed from a point with 0...16 fractional bits.

CartoType::TPointFixed::TPointFixed	(	const TPoint &	aPoint,
		TFixed::TRaw
	)		`[inline]`

Construct a TPointFixed from a point containing raw values (with 16 fractional bits).

void CartoType::TPointFixed::operator*= ( const TFixed & aFixed ) [inline]

Multiply the vector represented by the point.

void CartoType::TPointFixed::operator+= ( const TPointFixed & aPoint ) [inline]

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

void CartoType::TPointFixed::operator-= ( const TPointFixed & aPoint ) [inline]

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

CT_EXPORT void TPointFixed::Polarize ( )

Convert a point to polar coordinates. The radius is stored in iX, the angle in radians in iY.

TPoint CartoType::TPointFixed::Rounded ( ) const [inline]

Return an integer point, rounding the values in the TPointFixed object to units.

TPoint CartoType::TPointFixed::Rounded64ths ( ) const [inline]

Return an integer point in rounded 64ths of the values in the TPointFixed object.

TFixed CartoType::TPointFixed::VectorLength ( ) const [inline]

Return the length of the vector represented by the point.

The x coordinate.

The y coordinate.
