I add some annotations in the image.Then I execute follow:
ImageEnVect1->IO->DoPrintPreviewDialog(iedMaxi, Caption, false, "#25171;#21360;#39044;#35272;");
The result image has no any annotations
But, when I execute:
ImageEnVect1->IO->DoPrintPreviewDialog(iedMaxi, Caption, true, "#25171;#21360;#39044;#35272;");
The result image also has no any annotations, but it should has annotations. Why?

Hi

The PrintAnnotations parameter is only for printing of "Wang Imaging Annotations" that are stored in the meta-data.

You should copy the objects to the back before calling the print code:

https://www.imageen.com/help/TImageEnVect.CopyObjectsToBack.html

Either copy your objects to a temporary TImageEnVect, call CopyObjectsToBack, and print, or call CopyObjectsToBack and then after printing call undo.

The follow is my code:
imgPrint->Assign(ImageEnVect1);
imgPrint->CopyObjectsToBack(true, true);
imgPrint->RemoveAllObjects();
imgPrint->IO->DoPrintPreviewDialog(iedtDialog, Caption, false, "UU");//, Caption, false, "#25171;#21360;#39044;#35272;");
When I run this program, it will show an error:
Floating point division by zero
My enviorment: Delphi XE 10.1 + Win10(64bit), my program is 64bit.

procedure TForm1.Print1Click(Sender: TObject);
begin
  // Save the image with vectorial objects
  ImageEnVect1.Proc.SaveUndo;
  // Merge vectorial objects with the background image
  ImageEnVect1.CopyObjectsToBack(True);
  // Do print preview
  ImageEnVect1.IO.DoPrintPreviewDialog();
  // Restore objects from the merge
  ImageEnVect1.Proc.Undo;
end;
