Detailed Description

Implements a color model that performs a linear interpolation to compute the pixel colors with intervals specified by the user.

Library: ilvmaps
This color model can be used to create images from an IlvMapRaster.

See also: IlvDefaultRasterRenderer.

Constructor & Destructor Documentation

§ IlvIntervalColorModel() [1/2]

IlvIntervalColorModel::IlvIntervalColorModel	(	const IlUChar *	redMap,
		const IlUChar *	greenMap,
		const IlUChar *	blueMap,
		IlUInt	colorCount,
		const IlInt *	limits,
		IlUInt	limitCount
	)

Creates an instance of IlvIntervalColorModel.

Parameters

redMap	The value of chars indicating the red component of the colors for the interval limits. The value can be between `0` and `255`. The first value of the array is for MinInt and the last value is for MaxInt. Intermediate limits are specified in the limits array.
greenMap	The value of chars indicating the green component of the colors for the interval limits. The value can be between `0` and `255`. The first value of the array is for MinInt and the last value is for MaxInt. Intermediate limits are specified in the limits array.
blueMap	The value of chars indicating the blue component of the colors for the interval limits. The value can be between `0` and `255`. The first value of the array is for MinInt and the last value is for MaxInt. Intermediate limits are specified in the limits array.
colorCount	The size of the arrays redMap, greenMap and blueMap.
limits	The values of the interval limits.
limitCount	The size of the array limits.

Note: The number of limits must be colorCount - 2.
