Examples

// Save current layer configuration (compress images as PNG)
ImageEnView1.IO.Params.IEN_Compression := ioPNG;
ImageEnView1.IO.SaveToStreamIEN( Stream );

// Load saved layers
ImageEnView1.IO.LoadFromStreamIEN( Stream );

// Save the layers of three TImageEnViews to a file
var
  fs: TFileStream;
begin
  fs := TFileStream.Create(FileName, fmCreate);
  ImageEnView1.IO.SaveToStreamIEN( fs );
  ImageEnView2.IO.SaveToStreamIEN( fs );
  ImageEnView3.IO.SaveToStreamIEN( fs );
  FreeAndNil(fs);
end;

// Load the layers
var
  fs: TFileStream;
begin
  fs := TFileStream.Create(FileName, fmOpenRead or fmShareDenyWrite );
  ImageEnView1.IO.LoadFromStreamIEN( fs );
  ImageEnView2.IO.LoadFromStreamIEN( fs );
  ImageEnView3.IO.LoadFromStreamIEN( fs );
  FreeAndNil(fs);
