Is possibile to read only exif information without load the entire file?
I have huge files and i need to get only exif data.
I'm using the loadfromfilefast but is not "fast" as i would :(

Is also possible to get all exif params in an array without read one by one?

thank you

gian

Look at iexMetaHelpers and ParamsFromFile in the help file or in the online help. T his does not load the entire file... it just loads the IO.Prams from the file.

uses ImageEnIO, iexMetaHelpers;
var
  iImageEnIO: TImageEnIO;
  iFilename: string;
begin
  iImageEnIO := TImageEnIO.Create(nil);
  try
    iImageEnIO.ParamsFromFile(iFilename);
    ListView1.InitializeList;
    ListView1.NewListForExif;
    ListView1.ReadListFromExif(iImageEnIO.Params);
  finally
    iImageEnIO.Free;
  end;
end;

uses iexMetaHelpers;
ListView1.InitializeList;
ListView1.NewListForExif;
ListView1.ReadListFromExif(ImageenView1.IO.Params);
