Description

    FIELD SIZE returns the dimensions of a field as integer parameters.
It allows each of these parameters to be scaled by its own scale factor.
FIELD SIZE is used to limit the range of parameters such as cropping
limits to a proportion of the size of a field.

Inputs

	input - field

Outputs

	X dimension - float
	Y dimension - float
	Z dimension - 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.
	Z scale
Applies a scale factor to the value output from the Z dimension port.

Example

	This network allows the upper limit of cropping to be set to a
chosen proportion of the image dimension by adjusting the X scale and
Y scale parameters of FIELD SIZE.
