18
19     $ puzzle-diff pic-a-0.jpg pics-a-1.jpg 0.102286
20
21     Compare two images, exit with 10 if they look the same, exit with 20 if
22     they don't (may be useful for scripts):
23
24     $ puzzle-diff -e pic-a-0.jpg pics-a-1.jpg $ echo $?  10
25
26     Compute distance, without cropping and with computing the average inten‐
27     sity of the whole blocks:
28
29     $ puzzle-diff -p 1.0 -c pic-a-0.jpg pic-a-1.jpg 0.0523151
