| ImageFunction | | public interface ImageFunction (Code) | | ImageFunction is a common interface for vector-valued functions which
are to be evaluated at positions in the X-Y coordinate system. At
each position the value of such a function may contain one or more
elements each of which may be complex.

| Method Summary | |
| void | getElements(float startX, float startY, float deltaX, float deltaY, int countX, int countY, int element, float[] real, float[] imag)
Returns all values of a given element for a specified set of
coordinates. | | void | getElements(double startX, double startY, double deltaX, double deltaY, int countX, int countY, int element, double[] real, double[] imag)
Returns all values of a given element for a specified set of
coordinates. | | int | getNumElements()
Returns the number of elements per value at each position. | | boolean | isComplex()
Returns whether or not each value's elements are complex. |
| getElements | | void getElements(float startX, float startY, float deltaX, float deltaY, int countX, int countY, int element, float[] real, float[] imag)(Code) | | Returns all values of a given element for a specified set of
coordinates. An ArrayIndexOutOfBoundsException may be thrown if
the length of the supplied array(s) is insufficient.
Parameters:
startX - The X coordinate of the upper left location to evaluate.
Parameters:
startY - The Y coordinate of the upper left location to evaluate.
Parameters:
deltaX - The horizontal increment.
Parameters:
deltaY - The vertical increment.
Parameters:
countX - The number of points in the horizontal direction.
Parameters:
countY - The number of points in the vertical direction.
Parameters:
real - A pre-allocated float array of length at least countX*countYin which the real parts of all elements will be returned.
Parameters:
imag - A pre-allocated float array of length at least countX*countYin which the imaginary parts of all elements will be returned; may benull for real data, i.e., when isComplex() returns false.
throws:
ArrayIndexOutOfBoundsException - if the length of the suppliedarray(s) is insufficient. |

Parameters:
real - A pre-allocated double array of length at leastcountX*countY in which the real parts of all elements will be returned.
Parameters:
