Hi

You are best to do this using selections. Please email me for an update that supports curved selections, like the following:

procedure TMainForm.btnCurvedSelectionClick(Sender: TObject);
const
  WAVE_HEIGHT = 0.4; // Wave selection is 40% height of image
  CURVE_COUNT = 6;   // Number of up and down curves
  CURVE_MULT  = 2.4; // How curved is the line? 1=half circle
var
  waveHt, i: Integer;
  waveWidth, curve, endX: Double;
begin
  ImageEnView1.Deselect();
  ImageEnView1.SelectionBase := iesbBitmap;

  waveHt    := Round( ImageEnView1.IEBitmap.Height * WAVE_HEIGHT );
  waveWidth := ImageEnView1.IEBitmap.Width / CURVE_COUNT;

  ImageEnView1.AddSelPoint( 0, 0 );
  ImageEnView1.AddSelPoint( 0, waveHt );

  curve := CURVE_MULT;
  endX := 0;
  for i := 1 to CURVE_COUNT do
  begin
    endX := endX + waveWidth;
    ImageEnView1.AddSelCurve( Round( endX ), waveHt, curve );
    curve := -1 * curve;   // reverse direction of curve
  end;

  ImageEnView1.AddSelPoint( ImageEnView1.IEBitmap.Width, 0 );
  ImageEnView1.EndSelect();
end;



You can then use ImageEnView1.Proc.CropSel(); to remove the selection, or create layers from the selection:

  ImageEnView1.LayersCreateFromSelection();
  ImageEnView1.CurrentLayer.SoftShadow.Enabled := True;
