I know you can flip an image horizontal or vertical. what about if there are any objects on the layer. how or can you flip them too?

Flip the IEBitmap in the selected layer and all selected bitmaps in the layer:
procedure TMainForm.Flip1Click(Sender: TObject);
var
  i: Integer;
  iIEBitmap: TIEBitmap;
begin
  // flip the base IEBitmap in the selected layer
  ImageEnVect1.IEBitmap.Flip(fdVertical);
  // find and flip all iekBITMAP objects in the selected layer
  for i := 0 to ImageEnVect1.SelObjectsCount - 1 do
    if ImageEnVect1.ObjKind[ImageEnVect1.SelObjects[i]] = iekBITMAP then
    begin
      iIEBitmap := ImageEnVect1.ObjBitmap[i];
      iIEBitmap.Flip(fdVertical);
    end;
  ImageEnVect1.Update;
end;

Thanks Bill, but the box does not flip. The box is a vector iekbox, not iekbitmap.

Of course... look at the code... this only flips iebitmap objects. It is not possible to flip other objects as far as I understand. You could reposition the object width or height to give the appearance of flipping. For some objects like text or memo objects it does not even make sense to flip them at all.

Hello you wish it had a property Angle to rotate their boxes.

Watch the Video Below.

Good luck.

TImageEnVect already has a rotate method, but only allows rotate in increments of 90 degrees for some objects. See the help file: 
ImageEnVect1.RotateObject(hobj, 90, ierImage);

The problem with achieving mouse or touch rotation of an TImageEnVect object is that there is no miRotateObject TIEMouseInteractVtItem and the current code only allows rotation of some objects in increments of 90 degrees.

To achieve this it would take some significant enhancements to the source code. I have no idea if it is even possible to accomplish. If the developers pursue this, then I suspect rotation of a layer with attached objects would function better. It may also require adding a RotateObjectsWhenRotatingLayer property as well.

Hi

A major overhaul of TImageEnVect is on the to-do list. You should vote for it in our upcoming survey.
