Why do you convert it to RAW? You can read the JPEG directly...

Drop a TImage component on the form (where the image will be displayed) and use the following code:

uses
  JPEG;

procedure TForm1.FormCreate(Sender: TObject);
var
  jpg : TJPEGImage;
begin
  jpg := TJPEGImage.Create;
  jpg.LoadFromFile('C:\DSC00064.JPG');
  Image1.Picture.Bitmap.Assign(jpg);
end;

i get an exception with access violation on adress FFFFFFFC.
i have a paintbox1 with a canvas..
so how can i convert from the jpeg file to the canvas?
I tryed allready Paintbox1.canvas.assign(jpg);
but this assign routine needs a TPersistent Object.

i solved the most of the problems by myself..
i used the Paintbox1.canvas.draw routine to get stuff from the jpeg image..
