Oh good grief.
man compare
The compare program returns 2 on error otherwise 0 if the images are
similar or 1 if they are dissimilar.
Line 1085 in scripts/build/output-distance.py:
def system (x):
print 'invoking', x
stat = os.system (x)
assert stat == 0
Now "compare" is called with the option -dissimilarity-threshold 1 which
presumably should cater for an exit status of 0.
I cannot manage with _any_ options to get a status of 0 even for
completely identical images. Probably a bug in this version of compare.
