When saving to PDF:
• Is it possible to determine the page format?
• Is it possible to determine other PDF metadata such as Author, Title, Subject, Keywords?

When saving to GIF:
• Is it possible to determine the duration of the GIF frames?

Hi Peter

It is not that easy to create a catch-all Params object. We would need to fill it with an amalgamation of all file params whenever read, and when set we would need to iterate through every property to determine what had changed and apply it.

Bill, thank you for your answer!

But my question was about MIO.SaveToFile (sorry for having written TImageEn in the question title): With MIO you have to cycle through all the images to set the Params of each and every image.

While this is useful for setting different Params for each image, it is cumbersome for setting identical Params for all images.

So MyMVImages.MIO.Params.GIF_DelayTime := 10; should not cause a compiler error but automatically set this Params to all images. This could be easily achieved with an overload.

The help file is your friend... use it!
See TImageEnIO.Params in the help file 

1. procedure TMainForm.FormCreate(Sender: TObject);
var
  a: TIOPDFPaperSize;
begin
  // Fill combobox with available PDF paper sizes
  cmbPaperSize.Clear;
  for a := Low(TIOPDFPaperSize) to iepAuto do
    cmbPaperSize.Items.Add(IEPaperSizeToStr(a));
  // Make "US Letter" the selected one
  cmbPaperSize.ItemIndex := cmbPaperSize.Items.IndexOf(IEPaperSizeToStr(iepLetter));
end;

// Set PDF paper size to user's selection
ImageEnView1.IO.Params.PDF_PaperSize := IEStrToPaperSize(cmbPaperSize.Text);



2. ImageEnView1.IO.Params.GIF_DelayTime := 10; // Set current frame to display for 1/10th of a second
