Method Detail

transform

public java.awt.geom.Point2D transform(java.awt.geom.Point2D source,
                                       java.awt.geom.Point2D dest)
                                throws TransformException

Description copied from interface: MathTransform2D

Transforms the specified ptSrc and stores the result in ptDst. If ptDst is null, a new Point2D 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.

Specified by:

transform in interface MathTransform2D

Overrides:

transform in class AbstractMathTransform

Parameters:

source - the specified coordinate point to be transformed.

dest - the specified coordinate point that stores the result of transforming ptSrc, or null.

Returns:

the coordinate point after transforming ptSrc and stroring the result in ptDst.

Throws:

TransformException - if the point can't be transformed.

transform

public void transform(double[] source,
                      int srcOffset,
                      double[] dest,
                      int dstOffset,
                      int length)
               throws TransformException

Description copied from interface: MathTransform

Transforms a list of coordinate point ordinal values. This method is provided for efficiently transforming many points. The supplied array of ordinal values will contain packed ordinal values. For example, if the source dimension is 3, then the ordinals will be packed in this order: (x₀,y₀,z₀, x₁,y₁,z₁ ...). The size of the passed array must be an integer multiple of MathTransform.getDimSource().

Specified by:

transform in interface MathTransform

Parameters:

source - the array containing the source point coordinates.

srcOffset - the offset to the first point to be transformed in the source array.

dest - the array into which the transformed point coordinates are returned. May be the same than srcPts.

dstOffset - the offset to the location of the first transformed point that is stored in the destination array.

length - the number of point objects to be transformed.

Throws:

TransformException - if a point can't be transformed.

transform

public void transform(float[] source,
                      int srcOffset,
                      float[] dest,
                      int dstOffset,
                      int length)
               throws TransformException

Description copied from interface: MathTransform

Transforms a list of coordinate point ordinal values. This method is provided for efficiently transforming many points. The supplied array of ordinal values will contain packed ordinal values. For example, if the source dimension is 3, then the ordinals will be packed in this order: (x₀,y₀,z₀, x₁,y₁,z₁ ...). The size of the passed array must be an integer multiple of MathTransform.getDimSource().

Specified by:

Overrides:

transform in class AbstractMathTransform

Throws:

TransformException

createTransformedShape

public java.awt.Shape createTransformedShape(java.awt.Shape shape)
                                      throws TransformException

Description copied from interface: MathTransform2D

Transform the specified shape. This method may replace straight lines by quadratic curves when applicable. It may also do the opposite (replace curves by straight lines). The returned shape doesn't need to have the same number of points than the original shape.

Specified by:

createTransformedShape in interface MathTransform2D

Overrides:

createTransformedShape in class AbstractMathTransform

Parameters:

shape - Shape to transform.

Returns:

Transformed shape, or shape if this transform is the identity transform.

Throws:

TransformException - if a transform failed.
