详细描述

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

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

成员函数说明

◆ alpha()

double Qwt3DColorMapColor::alpha ( ) const

返回 alpha 值

返回: 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

返回: 颜色数量

◆ createVector()

ColorVector & Qwt3DColorMapColor::createVector ( ColorVector & vec )

overridevirtual

重载 Qwt3DColor .

◆ manualMax()

double Qwt3DColorMapColor::manualMax ( ) const

返回手动区间的最大值

返回: 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

返回: 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

实现了 Qwt3DColor.

◆ presetName()

QString Qwt3DColorMapColor::presetName ( ) const

返回构造时传入的 preset 名称

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

◆ setSourceAxis()

void Qwt3DColorMapColor::setSourceAxis ( Qwt3DColorSource source )

Selects which coordinate of the (x, y, z) functor argument feeds the colormap

Selects which coordinate of the (x, y, z) argument feeds the colormap; the active range (setActiveRange()) applies to the selected axis

参数

source The source coordinate (ColorFromX, ColorFromY or ColorFromZ)

The default ColorFromZ preserves the historical behavior. The active range pushed by the owning item via setActiveRange() applies to the selected coordinate. The legend color vector is unaffected: it always shows the colormap over the active range.

◆ sourceAxis()

Qwt3DColorSource Qwt3DColorMapColor::sourceAxis ( ) const

Returns the source coordinate selection (default ColorFromZ)

Returns the source coordinate selection

返回: The current Qwt3DColorSource (default ColorFromZ)

◆ useManualInterval()

bool Qwt3DColorMapColor::useManualInterval ( ) const

返回是否使用了手动区间

返回: true 如果通过 setInterval() 设置了手动区间
