- poor SMP scaling in benchmark
kernel changes? benchmark an old version
- gbandjoin in Python seems to be broken
7.12 seems to run about the same speed
b = VImage.VImage.gbandjoin ([a, a, a])
avg is different? used to 120.134, now 120.151
fails with a typecheck error
vips-7.18 had 151 as well
$ ./try157.py
Traceback (most recent call last):
File "./try157.py", line 6, in <module>
b = VImage.VImage.gbandjoin ([a, a, a])
TypeError: in method 'VImage_gbandjoin', argument 1 of type
'std::vector< vips::VImage,std::allocator< vips::VImage > >'
probably all IMAGEVEC wrappers are duff like this ... the proto should take
a std::allocator too?
however, this works?
b = a.lin ([1,2,3], [4,5,6])
how odd
- vip2dj -rotate STILL does not always work, eg. try
/data/john/study2/small0.v ... should NOT rotate, but it does
- rename "header" program? or maybe use "vips header" instead?
it's disabled on ubuntu due to a name clash
- import ~/summer-demo/summer.tif fails with "unable to read embedded
profile", is this a bug? better err msg would be good
trying to catch errors now, but is it working? not sure
WONTFIX for 7.20

in the vips generic property setter? or do it in nip2?
