详细描述

A curve fitter using a spline interpolation

The default setting for the spline is a cardinal spline with uniform parametrization.

QwtSpline, QwtSplineLocal

构造及析构函数说明

QwtSplineCurveFitter()

QwtSplineCurveFitter::QwtSplineCurveFitter

(

)

Constructor

Creates a spline curve fitter with a cardinal spline using uniform parametrization.

~QwtSplineCurveFitter()

QwtSplineCurveFitter::~QwtSplineCurveFitter ( )

override

Destructor

Deletes the internal spline object.

成员函数说明

fitCurve()

QPolygonF QwtSplineCurveFitter::fitCurve ( const QPolygonF &  points ) const

overridevirtual

Find a curve which has the best fit to a series of data points

参数

points

Series of data points

返回

Fitted Curve

参见

fitCurvePath()

实现了 QwtCurveFitter.

fitCurvePath()

QPainterPath QwtSplineCurveFitter::fitCurvePath ( const QPolygonF &  points ) const

overridevirtual

Find a curve path which has the best fit to a series of data points

参数

points

Series of data points

返回

Fitted Curve

参见

fitCurve()

实现了 QwtCurveFitter.

setSpline()

void QwtSplineCurveFitter::setSpline

(

QwtSpline *

spline

)

Assign a spline

The spline needs to be allocated by new and will be deleted in the destructor of the fitter.

参数

spline() [1/2]

QwtSpline * QwtSplineCurveFitter::spline

(

)

Get the spline (non-const version)

返回

Spline

setSpline()

spline() [2/2]

const QwtSpline * QwtSplineCurveFitter::spline

(

)

const

Get the spline (const version)

返回

Spline
