John Cupitt 2b482fc2cf seems to work! 2017-01-27 16:43:37 +00:00
John Cupitt 7136053451 sort max/min results by y and x coordinate
previously the list of maxima or minima found by max/min were in found
order, so essentially random

they now sort equal values by y then x coordinate, so the results are
consistent between runs, provided there are fewer maxima / minima than
are being tracked

John Cupitt 36761bcfd7 make vips_gaussnoise() pixels reproducible
previously, pixel values were regenerated on every calculation, so they
changed on recomputation

pixel values are now generated from the pixel (x, y) coordinate plus a per-call
seed

John Cupitt fa3c92c19b add CLAHE
vips_hist_local() has a new param, max_slope, which sets the maximum
amount that the local contrast can be boosted by -- CLAHE

see https://github.com/jcupitt/libvips/issues/268

also fix a couple of small range problems

- scale by 255, not 256, to avoid an overflow
- cum hist includes the current value, so sum to <= target, not < target

John Cupitt c5e675f7db fix --vips-cache-max etc.
--vips-cache-max, --vips-cache-max-memory and --vips-cache-max-files were not
working and probably hadn't been for a while

vipsthumbnail.c turns off the operation cache, it's not useful for
the same operation repeated across many files

John Cupitt 85be55fe4f add vips_image_get_fields()
helps bindings (which struglle with vips_image_map()) get a list of

older libgsfs can't save zip64 and will fail silently for very large
output trees ... improve the slightly sketchy >4gb detection in dzsave

John Cupitt ca7b51fb9e revise header get/set
rework header.c

- built-in enum fields, like "interpretation" are handled as enums, not
  ints
- vips_image_get_*() functions always convert to the target type if they
  can
- rename "field" to "name" in the docs
- clarify docs
