Detailed Description

A contour consisting of owned points with integer coordinates, which are all on the curve; the contour thus consists of straight line segments. For contours with off-curve points use CContour.

Constructor & Destructor Documentation

◆ COnCurveContour() [1/2]

CartoType::COnCurveContour::COnCurveContour ( const MContour aContour)
inlineexplicit

Creates a contour by copying another contour.

◆ COnCurveContour() [2/2]

CartoType::COnCurveContour::COnCurveContour ( const TRect aRect)
inline

Creates a contour from an axis-aligned rectangle.

Member Function Documentation

◆ AppendPoint() [1/2]

void CartoType::COnCurveContour::AppendPoint ( const TOutlinePoint aPoint)
inlineoverridevirtual

Appends a point to the contour, but only if it differs from the previous point.

Implements CartoType::CContourBase< TPoint >.

◆ AppendPoint() [2/2]

void CartoType::COnCurveContour::AppendPoint ( double  aX,
double  aY 
)
inline

Appends a point to the contour whether or not it differs from the previous point.

◆ AppendPoint64ths()

void CartoType::COnCurveContour::AppendPoint64ths ( const TPointFP aPoint)
inline

Converts a point from floating-point to point in 64ths and appends it.

◆ AppendTransformedPoint64ths()

void CartoType::COnCurveContour::AppendTransformedPoint64ths ( const TTransform aTransform,
const TPointFP aPoint 
)

Applies a transform to a point, converts it from floating-point to 64ths, and appends it.

◆ MayHaveCurves()

bool CartoType::COnCurveContour::MayHaveCurves ( ) const
inlineoverridevirtual

Returns true if the path may have off-curve points.

Implements CartoType::MPath.

◆ operator=() [1/2]

COnCurveContour & CartoType::COnCurveContour::operator= ( const MContour aContour)
inline

TOutlinePoint * CartoType::COnCurveContour::OutlinePointData ( )
inlineoverridevirtual

Returns a writable pointer to TOutlinePoint data if possible.

Implements CartoType::MWritableContour.

◆ PointData() [1/2]

const TPoint * CartoType::COnCurveContour::PointData ( ) const
inline

Returns a constant pointer to the point data.

◆ PointData() [2/2]

TPoint * CartoType::COnCurveContour::PointData ( )
inlineoverridevirtual
