Constructs a new TLcdContourUtil class.

Method Details

getLinearLevels

public double[] getLinearLevels(ILcdMatrixView aMatrix,
 int aNumberOfLevels,
 double aMinLevel,
 double aMaxLevel)

Returns the different levels using a linear subdivision.

Parameters:

aMatrix - the ILcdMatrixView to compute the levels from.

aNumberOfLevels - The number of levels to compute.

aMinLevel - The minimum level. Only values above this level will be considered when computing the subdivision.

aMaxLevel - The minimum level. Only values below this level will be considered when computing the subdivision.

Returns:

An array of length aNumberOfLevels containing the levels for a linear subdivision.

getLogarithmicLevels

public double[] getLogarithmicLevels(ILcdMatrixView aMatrix,
 int aNumberOfLevels,
 double aMinLevel,
 double aMaxLevel)

Returns the different levels using a logarithmic subdivision. For a logarithmic subdivision, either aMatrix should only contain positive values, or aMinLevel should be larger than zero.

Parameters:

aMatrix - the ILcdMatrixView to compute the levels from.

aNumberOfLevels - The number of levels to compute.

aMinLevel - The minimum level. Only values above this level will be considered when computing the subdivision.

aMaxLevel - The minimum level. Only values below this level will be considered when computing the subdivision.

Returns:

An array of length aNumberOfLevels containing the levels for a logarithmic subdivision.
