Is there a way to undo a stream of commands like the ones below?
ImageEnVect.Proc.SaveUndo;
{ Merge vectorial objects with the background image }
ImageEnVect.CopyObjectsToBack(Antialias.Checked,
AdaptBitmapPixelFormat.Checked);
ImageEnVect.RemoveAllObjects;
ImageEnVect.Update;
Thanks.

TImageEnVect.ObjUndoMode
Declaration
property ObjUndoMode: TIEVUndoMode;
Description
This property allows you to share the Undo/Redo system between image processing and vectorial objects. The default value (ieumSeparated) separates the two systems.
Example
ImageEnVect1.ObjUndoMode := ieumShared;
ImageEnVect1.ObjAutoUndo := true;
ImageEnVect1.Proc.UndoLimit := 10;
From now you can do Undo of image processing or vectorial objects just calling:
ImageEnVect1.Proc.Undo;
ImageEnVect1.Proc.ClearUndo;
otherwise if ObjUndoMode is ObjUnmSeparated then both ObjSaveUndo, Proc.SaveUndo and ObjUndo, Proc.Undo and ObjClearUndo, Proc.ClearUndo must be used.
Set ObjUndoMode := ieumShared then Proc.Undo, changes both the processing changes and any object changes.
A small demo will be posted to the users section.

Thanks Bill. I was not aware of the mode.
Now, would the undo command undo 2 commands one after another in one time?
I am doing a copyobjectstoback and a removeall objects.
Where can I find the user's area for the demo?
Thanks. |

Thanks Bill. Your demo works fine but not my code :(
When i undo, the box comes back but when i move it, the raster image of the box is still there. Not in your demo though..
Will try to find out what is wrong.

| Bill, i am emailing you a modified project. Create a box, merge it and undo. Move the box and you will see the box bitmap still there. If you do not get it in a few, i may have an old email address. |

Pierre,
You are using an older version of ImageEn than I am using. When I compile your project here it works as expected.

When i tried your demo originally, it worked fine. No problem. I made some modifications and it behaves like mine.
Let me reload your original source code again..And try it..
Thanks. |

Yep, your demo works fine. There is something i am modifying that makes the bitmap stay. I'll troubleshoot.
Thanks. |

| Got it..When in your demo I changed in the imageenvect component the objundomode property to shared instead of separated, it then left the bitmap after the undo. |

You should be using ieumSeparated in order to use ImageEnVect1.Proc.Undo. See the simplified version I emailed you.

Got it. I guess i got confused. I thought i had to use ieumShared to use proc.undo for both vector and bitmap.
Let me look at your demo.
Thanks. |

No you are correct... it should be ieumShared ... you got me confused.
procedure TForm1.FormCreate(Sender: TObject);
begin
ImageEnVect1.ObjUndoMode := ieumShared;
ImageEnVect1.ObjAutoUndo := False;
ImageEnVect1.ObjUndoLimit := 10;
IERegisterFormats;
OpenPictureDialog1.Filter := GraphicFilter(TGraphic);
end;
The simpler demo uses ieumShared!
If the simple demo sent by email does not work as is then you should update ImageEn. What version are you using anyway?
