TImageEnView.CalcSelectionCentroid
Declaration
function CalcSelectionCentroid(): TPoint;
Description
Calculates the coordinates of the selection's centroid (in bitmap coordinates).
The centroid is the geometric center of a shape, i.e. the mean position of all the points in the figure.
Note: Works with all selection types, including selection masks
procedure TMDIChild.ImageEnView1MouseMove(Sender: TObject; Shift: TShiftState; X, Y: Integer);
begin
Label1.Caption := 'Area: ' + IntToStr( Round( ImageEnView1.CalcSelectionArea() ));
Label2.Caption := 'Perimeter: ' + IntToStr( Round( ImageEnView1.CalcSelectionLen() ));
Label3.Caption := 'Centroid: ' + IntToStr( ImageEnView1.CalcSelectionCentroid.X ) + ',' + IntToStr( ImageEnView1.CalcSelectionCentroid.Y );
end;
