Do you mean make change the zoom of imageenview1 so it displays at the same size as the image in imageenview2?

ok.

begin
imageEnvivew1.io.loadfromfile(ExtractFilePath(Application.ExeName)+'tmp1.bmp');
imageEnvivew2.io.loadfromfile(ExtractFilePath(Application.ExeName)+'tmp1Resampled.bmp');

after
... // how can i detect the size of imageEnvivew2, ? unknow Resampled and equal, sync to mageEnvivew1.zoom;
... //?:=imageEnvivew2.IEBitmap.Width -+ <> imageEnvivew1.IEBitmap.Width
... //imageEnvivew2.Zoom:=imageEnvivew1.Zoom * or / ?

ComboBox1.Text := IntToStr(trunc(imageEnvivew1.Zoom));
ComboBox2.Text := IntToStr(trunc(imageEnvivew2.Zoom));

end;

If you want the image in ImageEnView2 to display at the width of the image in ImageEnView1, wouldn't that just be:

ImageEnView2.Zoom := ImageEnView1.IEBitmap.Width * ImageEnView1.Zoom / ImageEnView2.IEBitmap.Width;

Otherwise please show some example screenshots.

thanks.
I did this and it gave the same result.

imageEnView2.Zoom := imageEnView1.zoom / (imageEnView2.IEBitmap.Width / imageEnView1.IEBitmap.Width);

Perhaps I'm not really following what you are trying to do. Can you attach some screenshots to better show it?

I want to do it manually in imageenview like on this site.
https://openmodeldb.info/models/4x-NomosUniDAT-bokeh-jpg

as ImageEnView1.RunTransition( iettRightLeft1, 2000);

I added the my project file.

Hi

Please try this:

// Slide Transition from old.bmp to new.bmp ensuring that both are shown as the same height
procedure TForm1.btnCompareClick(Sender: TObject);
const
  Display_Zoom = 100;
  Center_Image = True;
var
  bh: Integer;
  iz: Double;
begin
  // Get original image as transition start
  ImageEnView1.IO.LoadFromFile( ExtractFilePath( Application.ExeName ) + 'old.bmp' );
  ImageEnView1.Zoom := Display_Zoom;
  if Center_Image then
    ImageEnView1.CenterImage()
  else
   ImageEnView1.SetViewXY( 0, 0 );

  bh := ImageEnView1.IEBitmap.Height;
  iz := ImageEnView1.Zoom;
  ImageEnView1.PrepareTransition();

  // Load second image as transition result (Zoom to match display size of old image)
  ImageEnView1.IO.LoadFromFile( ExtractFilePath( Application.ExeName ) + 'new.bmp' );
  ImageEnView1.Zoom := iz / ( ImageEnView1.IEBitmap.Height / bh );
  if Center_Image then
    ImageEnView1.CenterImage()
  else
   ImageEnView1.SetViewXY( 0, 0 );

  // Run the transition
  ImageEnView1.TransitionParams.AlternativeStyle := True;  // Include transition line
  ImageEnView1.TransitionParams.WipeLineColor := clYellow;
  ImageEnView1.RunTransition( iettRightLeft, 3000 );       // Wipe Right to Left
end;

oh thank you.
Can we do it without effects? When you hold it with the mouse and drag it, the other image appears.
Just like the one on this site.

Hi

That would be a lot more work.

You'd need to create two bitmaps and then scale them to the display size (i.e. making them both the same size).

You could then pass them to:

http://www.imageen.com/help/TImageEnProc.PrepareTransitionBitmaps.html

And in your mouse up event call:

http://www.imageen.com/help/TImageEnProc.CreateTransitionBitmap.html

Passing the display TImageEnView.IEBitmap and the percentage of the x position.
Don't for get to call ImageEnView1.Update after setting ImageEnView1.IEBitmap.

I did it with a different method. With system.Timage. but I could not apply it to imageenview. I couldn't adapt.
I want to do this with imageenview.
Can you help me adapt it to imageenview?

my code for Timage

procedure TForm4.MoveControl(AControl: TControl; const X, Y: Integer);
var
  lPoint: TPoint;
begin
  lPoint := AControl.Parent.ScreenToClient
    (AControl.ClientToScreen(Point(X, Y)));
     AControl.Left := lPoint.X - AControl.Width div 2;
       if AControl.Left>TImage1.Width then
         AControl.Left:=TImage1.Width;    end;

procedure TForm4.shape1MouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
    if ssLeft in Shift then
    begin
      MoveControl(Sender as TControl, X, Y);
      TImage0.Width:=shape1.Left-1;
    end
end;

procedure TForm4.FormCreate(Sender: TObject);
begin
  TImage0.Left:=1;
  TImage1.Left:=1;

 TImage0.Top:=1;
  TImage1.Top:=1;
end;

procedure TForm4.FormShow(Sender: TObject);
begin
 TImage0.Width:= TImage1.Width Div 2;
 shape1.Left:=TImage0.Width+1;
shape1.Top:=TImage1.Top;
shape1.Height:=TImage1.Height;
end;

Sorry, in v13.0.0 and older versions you need to add a line to the TIEImageCompareInteraction.PaintBackBuffer() method:

procedure TIEImageCompareInteraction.PaintBackBuffer(BackBuffer: TIEBitmap);
var
  iev: TImageEnView;
  ww, hh, lx: Integer;
  bmp1, bmp2: TIEBitmap;
begin
  iev := TImageEnView(fParent);

...

  lx := Round( iev.ClientWidth * fLineX );
  if fScreenBitmapX <> lx then
  begin
    // Reset the transition - needed for ImageEn versions <= 13.0.0
    fTransition.CreateBitmap( 0, fScreenBitmap.VclBitmap );    // <<<<<<<<<<<<<< ADD THIS LINE

    // Generate our display image
    fTransition.CreateBitmap( fLineX * 100, fScreenBitmap.VclBitmap );

...
  end;

  fScreenBitmap.DrawToTIEBitmap( BackBuffer, 0, 0 );
end;

Adding zoom would increase the complexity quite a bit. Are you a registered user or just using a trial?

I am using the trial version. Zoom is very important for this project. Otherwise it doesn't make much sense. It is necessary to see the changing details and pixels in the pictures.

Hi

I'm sorry we can only create custom demos for registered users.

You can implement zoom in the demo by scaling the values that are passed to PrepareTransition by the zoom (of the display ImageEnView). You'll also need to draw only the visible area (i.e. offset by ViewX and ViewY) to the BackBuffer bitmap in the BackBuffer paint event.

See:

http://www.imageen.com/help/TIEBitmap.DrawToTIEBitmap.html
