CImage:DistanceUnits

The DistanceUnits method returns the name of the units used to quote distance measurements. If the image has a world coordinate system ("WCS") calibration, this uses WCS units.

Syntax

sUnits = CImage:DistanceUnits()

On success, this method returns sUnits as a string

On failure, this method returns nil.

Remarks

If the image has a WCS calibration, this returns a WCS units. If there is no WCS calibration, measurements are reported in pixels. This method works even if the image has no WCS calibration.

Example

Assume a displayed image has a WCS calibration in microns per pixel. The following script returns the name of the WCS distance units:

I = V:GetImage()	-- load the image from an Image window
s = I:DistanceUnits()	-- return the units string
Printf("Distance units= '%s'", s )	-- result: Distance units= 'microns'
