Hi

Why I can not open pdf in ImageenMView?
Please add it option to ImageenMView.
I think I can open in ImageenFolderView.

Hi Ali

You can open a PDF file in ImageEnMView, just ensure you have copied iepdf32.dll to your EXE folder:

Hi Ali

Are you using ImageEnMView1.MIO.LoadFromFilePDF()?

Also, see the demo:

\Demos\Other\PDFViewer\PdfViewer.dpr

Hi Nigel

Are you using ImageEnMView1.MIO.LoadFromFilePDF()?
No.
I copied with regular Windows copy.

Also, see the demo:
\Demos\Other\PDFViewer\PdfViewer.dpr
I will test it.

Thank you for your help.

Hi Ali

TImageEnMView.CopyToIEBitmap() will only copy a specific frame from a TImageEnMView.

If you attach a TImageEnView to your TImageEnMView then it will show all of the frames:

// Show thumbnail preview of all pages of a PDF document
ImageEnView1.PdfViewer.Enabled := True;
ImageEnMView1.AttachedImageEnView := ImageEnView1;
ImageEnView1.IO.LoadFromFilePDF( 'C:\document.pdf' ); // NOTE: Loading into TImageEnView, not TImageEnMView

Hi Ali

Ensure you are calling ImageEnMView.AttachedImageEnView, not ImageEnView.

Hi Nigel

I checked you were right.

I want to save image content of ImageEnView1 PDF file opened to other temporary place and load again with ImageEnView1.
As same as below which show error: "PDF document is not open".
// Show thumbnail preview of all pages of a PDF document
ImageEnView1.PdfViewer.Enabled := True;
ImageEnMView1.AttachedImageEnView := ImageEnView1;
ImageEnView1.IO.SaveToFile('C:\SCM\documents\doc.pdf');
ImageEnView1.IO.LoadFromFilePDF( 'C:\SCM\documents\doc.pdf' ); // NOTE: Loading into TImageEnView, not TImageEnMView

Hi

In your code above, when you call ImageEnView1.IO.SaveToFile() you have not yet loaded or added any content to the PDF, so there is nothing to save.

Hi Ali

Have you tried the demo:

\Demos\Other\PDFViewer\PdfViewer.dpr

Does that work correctly for you?

Hi Ali

Change your ImageSelect event as follows:

procedure TForm1.ImageEnMView1ImageSelect(Sender: TObject; idx: Integer);
var
  fn: string;
begin
  fn := ImageEnMView1.ImageFileName[ idx ];
  if LowerCase( ExtractFileExt( fn )) = '.pdf' then
  begin
    ImageEnView1.PdfViewer.Enabled := True;
    ImageEnView1.IO.LoadFromFilePDF( fn );
  end
  else
  begin
    ImageEnView1.PdfViewer.Enabled := False;
    ImageEnMView1.CopyToIEBitmap(idx, ImageEnView1.IEBitmap);
    ImageEnView1.Update;
  end;
end;
