Hi,

I am adding an image to an existing PDF. I want to be able to edit/delete/move this image but not other objects. How can I do this?

Thanks

Hi Ken

There is no functionality for that at this time. But you could try resetting the Selected Object:

When you get an ieiPDFObjectSelected event in OnUserInteraction:

Hi Nigel,

I have tried the following but it doesn't stop the object being selected. I have also tried setting the SelectedObject to -1. So how can I stop an object being selected?

procedure TfrmMain.ImageEnView1UserInteraction(Sender: TObject; Event: TIEUserInteractionEvent; Info: Integer);
begin
  if Event=ieiPDFObjectSelected then
  begin
    ImageEnView1.PdfViewer.ClearSelection;
  end;
end;

Thanks

Or just preventing deletion would be fine.

If I store the number of objects into a variable when opening the pdf this works:

if (Event=ieiPDFObjectSelected) then
  begin
    ImageEnView1.PdfViewer.AllowObjectEditing:=
      ImageEnView1.PdfViewer.SelectedObject>=NumObjects;
  end;
