Description

    FIELD PARAMS is a module provided for the Oxford University Osney
Labs custom software for visualisation of experimental data.
FIELD PARAMS returns the X and Y dimensions of a field as integer parameters,
and the minimum and maximum values of the field as float parameters.
It allows each of these parameters to be scaled by its own scale factor.
FIELD PARAMS is used to provide the GENERATE COLORMAP module with the
range of the data values (cf COLOR RANGE), while also allowing the user
to modify the colour range.  It also provides the X dimension ofthe field
as an upper limit to the ANIMATE INT module which controls the position
of the viewable window.

Inputs

	input - field

Outputs

	X dimension - integer
	Y dimension - integer
	Min	    - float
	Max	    - float

Parameters

	X scale
Applies a scale factor to the value output from the X dimension port.
	Y scale
Applies a scale factor to the value output from the Y dimension port.
	Min scale
Applies a scale factor to the value output from the Min port.
	Max scale
Applies a scale factor to the value output from the Max port.

Example

	The networks view1.net and view4.net use FIELD PARAMS
