I solved it by changing some more code, generating the tuple key by the image hash. In this way the PDF file size decrease a lot, similar to using a PDF printer.

void PdfDraw::DrawImageOp(int x, int y, int cx, int cy, const Image& _img, const Rect& src, Color c)
{
	Image img = _img;
	if(!IsNull(c))
		img = CachedSetColorKeepAlpha(img, c);
	
  //Tuple2<int64, Rect> key = MakeTuple(img.GetSerialId(), src);
	Tuple2<int64, Rect> key = MakeTuple(img.GetHashValue(), src);
	int q = images.Find(key);
	if(q < 0)
	{
		//q = images.GetCount();
		//images.Add(key, img);
		
	  Image h = sJPEGDummy();
		q = images.GetCount();
		images.Add(key, h);
		data = JPGEncoder(40).SaveString(img);
		img = h;
	}
	
	if(img.GetSerialId() == sJPEGDummy().GetSerialId())
		jpeg.Add(data);
	
	page << "q "
	     << Pt(cx) << " 0 0 " << Pt(cy) << ' '
	     << Pt(x) << ' ' << Pt(pgsz.cy - y - cy)
	     << " cm /Image" << q + 1 << " Do Q\n";
	     
}
