CImage:DistanceWcsStr The DistanceWcsStr method calculates the distance in WCS units between 2 image points measured in world coordinates and returns the result as a string. The related Distance method computes the Distance for pixel coordinates. Syntax
RemarksThe DistanceWcsStr method returns a distance in world coordinate units as a string. Also see the related DistanceWcs method that returns the world coordinate calibrated distance as a number. ExampleAssume an image is displayed and attached to a CImageView named V. The following script measures the Distance between between two points (x1,y1) and (x2,y2) when the coordinates are in distance units (pixels, mm, microns, etc.):
Alternatively, the following example supposes an astronomical image with an equatorial calibration and that the points are expressed in angular units:
