// uses jpeg; var JP : TJpegImage; B : TBitmap; begin JP := TJpegImage.Create; JP.LoadFromFile("C:\Picture.jpg"); B := TBitmap.Create; B.Assign(JP); B.SaveToFile("C:\BMPPicture.bmp"); B.Free; JP.Free; end;

Вот тебе простой пример:

procedure TfrmMain.CustomItem5Click(Sender: TObject);

var
jpgImg: TJPEGImage;
begin
if OpenPictureDialog1.Execute then
imgMain.Picture.LoadFromFile(OpenPictureDialog1.FileName);
BEGIN
if SavePictureDialog.Execute then
BEGIN
// create the jpeg-graphic
jpgImg := TJPEGImage.Create;
// assign the bitmap to the jpeg, this converts the bitmap
jpgImg.Assign(imgMain.Picture.Bitmap);
// and save it to file
jpgImg.SaveToFile(ChangeFileext(SavePictureDialog.filename, "_thumb.jpg" ));

end ;

END;
END;
