I just patched the sketch:

uses fpimage,fpcanvas,fpwritepng, fpwritejpeg,fpimgcanv;

Var
  Image : TFPMemoryImage;
  Canvas : TFPimageCanvas;

begin
  // Create image,
  Image:=TFPMemoryImage.Create(640,480);
  Image.UsePalette:=False;
  // Create canvas.
  Canvas:=TFPImageCanvas.Create(Image);
  Canvas.Pen.Color:=colRed;
  Canvas.Ellipse(50,50,150,150);
  Canvas.Rectangle(50,50,150,150);
  // Free canvas
  Canvas.Free;
  Image.SaveToFile('myfile.png',TFPWriterPNG.Create); // Write as png
  Image.SaveToFile('myfile.jpg',TFPWriterPNG.Create); // Alternatively, write as jpg
  // Free Image.
  Image.Free;
end.
