CImage:AreaUnits

CImage:AreaUnits

The AreaUnits method returns the name of the units used to quote area measurements .If the image has a world coordinate system calibration, this uses WCS units.

Syntax

sUnits = CImage:AreaUnits()

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 unit with squared dimensions. If there is no WCS calibration, measurements are reported in square pixels. This method works even if the image has no WCS calibration.

Example

Assume a displayed image has a WCS calibration in cm per pixel. The following script fragment returns the name of the WCS area measurements units:

I = V:GetImage()	-- load the image from a display window
s = I:AreaUnits()	-- return the units string
Printf("Area units= '%s'", s )	-- result: Area units= 'cm^2'
