Hello, although you said in the introduction that jpegtran-scans are used on the large image JPG, I still don't know how to use it. I can only change the small image now, but the large image is not available. Please help me, thank you!

I used you jpg.py script process my 1.jpg and 2.jpg

  • 1.jpg size is 272 KB
  • 2.jpg size is 103 KB

I change this script below:

if max(len(i) for i in c1) >= (273 * 1024)/20 - 8:
#  print "ERROR: The first image file has a segment that is too big!",
#  print "Maybe save it as progressive or reduce its size/scans."
  sys.exit()

It's run, but No processing image. please help me, thanks!
