Hi

I use a TImageEnVect to see a TIFF File.
I have loaded the TIFF Image, and I would like it to be Fit To page or zoomed to a specific level depending on user preselection.

How do I set these values just after image has been loaded?

Regards
Michael

Hi

Set it to a specific zoom using:

http://www.imageen.com/help/TImageEnView.Zoom.html


Or make it shrink to window size automatically using AutoShrink:

Or manually using Fit:

procedure TForm1.ImageEnView1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
{ ImageEnView Mouse Down. }
var
  iZoom: double;
begin
  if Button = mbLeft then
  begin
    iZoom := ImageEnView1.Zoom + 25;
    ImageEnView1.ZoomAt(x, y, iZoom, False);
  end
  else
  begin
    iZoom := ImageEnView1.Zoom - 25;
    ImageEnView1.ZoomAt(x, y, iZoom, False);
  end;
end;
