public IndexColorModel getColorModel()
#getColors ).
getColorModel in interface ColorMapTransform<LinearColorMapElement>visibleBand - The band to be made visible (usually 0). All other bands, if any will be ignored.numBands - The number of bands for the color model (usually 1). The returned color model will renderer only the visibleBand and ignore the others, but the existence of all numBands will be at least tolerated. Supplemental bands, even invisible, are useful for processing with Java Advanced Imaging.
RenderedImage objects with values in the #getRange range.
public SampleModel getSampleModel(int width,

public double derivative(double value)
throws TransformException

TransformException - if the derivative can't be evaluated at the
specified point.

transform in interface MathTransform1Dvalue - The value to transform.
TransformException - if the value can't be transformed.
public Matrix derivative(DirectPosition point)
throws MismatchedDimensionException,
TransformException
MathTransformN×M. The elements of the matrix
{en,m : n=0..(N-1)}
form a vector in the output space which is parallel to the displacement
caused by a small change in the m'th ordinate in the input space.
For example, if the input dimension is 4 and the
output dimension is 3, then a small displacement
(x0, x1, x2, x3)
in the input space will result in a displacement
(y0, y1, y2)
in the output space computed as below (en,m
are the matrix's elements):
[ y0 ] [ e00 e01 e02 e03 ] [ x0 ]
[ y1 ] = [ e10 e11 e12 e13 ] [ x1 ]
[ y2 ] [ e20 e21 e22 e23 ] [ x2 ]
[ x3 ]
derivative in interface MathTransformpoint - The coordinate point where to evaluate the derivative. Null
value is accepted only if the derivative is the same everywhere.
For example affine transform accept null value since they produces
identical derivative no matter the coordinate value. But most map
projection will requires a non-null value.

This method never returns an internal object: changing the matrix
will not change the state of this math transform.

the expected dimension.

specified point.public int getSourceDimensions()

ptDst. If ptDst is null, a new
DirectPosition object is allocated and then the result of the
transformation is stored in this object. In either case, ptDst,
which contains the transformed point, is returned for convenience.
If ptSrc and ptDst are the same object,
the input point is correctly overwritten with the transformed point.

TransformException - if a point can't be transformed. Some implementations will stop
at the first failure, wile some other implementations will fill the untransformable
points with NaN values, continue and throw the exception
