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 );
