ConvertFromSquarePixels() protected static method

Converts an area in pixels into the given units given some particular pixel spacing.

Thrown if is a physical unit of measurement and is not calibrated.

area	double	The area of pixels to be converted.
units	ClearCanvas.Dicom.Iod.Units	The units into which the area should be converted.
pixelSpacing	PixelSpacing	The pixel spacing information available.
return	double
