f3326c8126 better vips_resize() for cubic/linear/nearest 
vips_resize() used to do most of a downsize with vips_shrink() and the
final 200 - 300% with vips_reduce(). This was correct for lanczos2/3,
but not right for linear/cubic, which need more shrink and less
reduce to avoid aliasing.

This patch makes vips_resize() leave the final 100 - 200% to
vips_reduce() for linear/cubic, and leave everything to reduce for
nearest.

b90145ca31 free pixel buffers on image close 
We were freeing pixel buffers on thread exit. This was convenient, but
meant that main thread buffers were not freed until program exit. As a
result, long-running programs which created main thread buffers would
slowly fill the operation cache with useless junk, forcing everything else out.

This change also frees pixel buffers on image close. This makes the
cache work much better in long-running programs, and can substantially
reduce memory use.

See https://github.com/jcupitt/libvips/issues/466

15878bffca Revert "free main-thread pixel buffers" 
This reverts commit 2a77301033.
 2016-06-06 06:38:18 +01:00
John Cupitt
2a77301033 free main-thread pixel buffers 
threads keep pixel buffers in thread-private storage, and free these
buffers on thread exit ... this means buffers created by the main thread will
only be freed on program exit!

if your program creates any main-thread buffers, these buffers will
eventually fill the operation cache and force everything else out,
making the cache useless

this patch explicitly frees main-thread pixel buffers on image close

	{
        	VIPS_COUNT_PIXELS( or, "vips_shrinkh_gen" );
	}

and on image close, if more than 100% of the pixels have been
calculated, you get a warning

only if you enable debugging, since this hurts perf slightly

2ea5c5f7e5 make python bandrank() work like bandjoin() 
we had a custom wrapper for bandjoin(), but bandrank(), a function with
an almost identical interface, did not ... this was confusing

bandrank() now has a custom wrapper too ... this breaks API
unfortunately, but hopefully very few people were using this thing and
it's better to make this change as soon as possible

25c3c49d1c better handling of cast+shift for non-int formats 
before, im.cast(uchar, shift = true) where im was float and tagged as
rgb16 would not shift the image, since it's unclear how much to shift a float
type by

now we do two casts: first, we guess the numeric range from the
interpretation, so rgb16 would be ushort, so we cast float->ushort;
second, we cast to the target type and do the shift on the way

de65da85b9 smarter conversion of float masks to int 
we were just rint()ing masks going from float -> int, but this could
give bad results in some cases, with output images becoming darker
or lighter, as individual elemets moved up or down

now we adjust the output scale to try to keep the overall brightness
the same, if we can

d126a733a0 better rgb16/grey16 conversion 
things like float tagged as rgb16 did not save well as png ... new
conversion rules should help
