- 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

|
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
