Detailed Description

Adapts a QwtColorMap (from qwt::core) for use as a Qwt3DColor.

Bridges the 2D colormap infrastructure into the 3D color functor system.

Member Function Documentation

◆ alpha()

double Qwt3DColorMapColor::alpha ( ) const

返回 alpha 值

Returns: alpha 值（0.0 ~ 1.0），默认 1.0

◆ colorCount()

unsigned Qwt3DColorMapColor::colorCount ( ) const

返回颜色向量中的颜色数量

Returns: 颜色数量

◆ createVector()

ColorVector & Qwt3DColorMapColor::createVector ( ColorVector & vec )

overridevirtual

Reimplemented from Qwt3DColor.

◆ manualMax()

double Qwt3DColorMapColor::manualMax ( ) const

返回手动区间的最大值

Returns: 手动最大值（仅当 useManualInterval() 为 true 时有意义）

◆ manualMin()

double Qwt3DColorMapColor::manualMin ( ) const

返回手动区间的最小值

Returns: 手动最小值（仅当 useManualInterval() 为 true 时有意义）

◆ operator()()

RGBA Qwt3DColorMapColor::operator()	(	double	x,
		double	y,
		double	z
	)		const

overridevirtual

Implements Qwt3DColor.

◆ presetName()

QString Qwt3DColorMapColor::presetName ( ) const

返回构造时传入的 preset 名称

Returns: preset 名称，如果通过 QwtColorMap* 构造则返回空字符串

◆ useManualInterval()

bool Qwt3DColorMapColor::useManualInterval ( ) const

返回是否使用了手动区间

Returns: true 如果通过 setInterval() 设置了手动区间
