Class DiaxialScoping

java.lang.Object

DiaxialScoping

All Implemented Interfaces:

Scoping

public final class DiaxialScoping
extends Object
implements Scoping

A scoping model based on two orthogonal axes (x,y). Each axis may be set to its own independent range of values, such that both ranges together specify a square sub-area. The scoping state is exposed in the 's' switch, as follows:

Switch	Controlled state	Default
s	The scoping state. 4 continguous numbers all padded to the same digit length, together representing the ranges of both axes (x,y). Each number is translated to a decimal by adding a leading decimal. An exception is made for numbers beginning with the letter N, which are always translated as 1.0. For example "s=00NN1030" is taken as x in the range 0.00 to 1.00 and y 0.10 to 0.30.	"0N0N" which specifies the full range on both axes.
