below code gives access violation if fSource is a bmp file larger than 90 mb (i last tried with 115 mb) and fDest is jp2.  Is it because of TSingleImage ? It works very good for all other bmp files.

Imaging Library Version: 0.26.4
Compiler: Delphi 2007
OS: Windows Vista Ultimate

var
    mImage: TSingleImage;
begin
   fSource := 'C:\x.bmp';
   fDest := 'C:\x.jp2';

    mImage := TSingleImage.Create;
    mImage.LoadFromFile(fSource);

    Imaging.SetOption(ImagingJpeg2000LosslessCompression, 1);

    try
      mImage.SaveToFile(fDest);
    finally
      mImage.Free;
    end;

end;
