TIEPolylineLayer.CalculateLength

Declaration

function CalculateLength(Units: TIEUnits): double;

Description

Returns the length/perimeter of the lines of the polyline layer.
If PolylineClosed = True, it will measure the perimeter. If not closed, it will only measure the length of all lines.

Note:
◼Use TImageEnView.SetScale to adjust the scale of units
◼Polyline measurement is less accurate than other layer types

Example

// Show length of current polyline in MM
ShowMessage( 'Length is ' + Trunc( TIEPolylineLayer( ImageEnView1.CurrentLayer).CalculateLength( ieuMillimeters )) + ' mm' );
