Subject: ETiffError TiffOpen

I have this error in Delphi5, Envision Library v2.01.

EnDcxGr, { for TDcxGraphic }
EnTifGr, { for TTifGraphic }
EnBmpGr, { for TBitmapGraphic }
EnPngGr, {for TPngGraphic}
EnIcoGr, { for TIconGraphic }
EnWmfGr, { for TMetaFileGraphic }
EnReg; { for image format registration }

procedure TForm1.FormCreate(Sender: TObject);
if FindDibGraphicClass('*.TIF') = nil then
RegisterDibGraphic('TIF', 'TIFF file', TTiffGraphic);

procedure TForm1.Button1Click(Sender: TObject);
var BlobStream:tblobstream;
BlobStream:=TBlobStream.create(dataset1.fieldbyname('pic') as tblobfield,bmWrite);

{All right! Then:}

BlobStream:=TBlobStream.create(dataset1.fieldbyname('pic') as tblobfield,bmRead);
BlobStream.Seek(0,soFromBeginning );
{In this block I have error. If I use BMP,PNG,JPG format or other, I have no error.
