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

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
2016-03-01 12:12:51 +00:00

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
see https://github.com/jcupitt/libvips/issues/397

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

use a better name for the dzsave temp dir
...
see https://github.com/jcupitt/libvips/issues/242
dzsave with deepzoom layout and fs container writes a temp dir called
dzsave-temp-324857 or similar, and makes sure that this directory does
not exist
after write, the foo_files and foo.dzi files are picked out to the
current dir and the temp removed

mask builders take prec, not integer
...
vips_gaussmat() and vips_logmat() used to default to float, but
vips_conv() defaulted to int ... so this failed:
vips gaussmat m.v 2 0.1 --separable
vips convsep k2.jpg x.jpg m.v
since we were using a small float mask with an integer convolution
This change makes everything int by default, with gaussmat having a new
param called --precision whose arg can be int or float.
The old @integer param is deprecated.

sorry :-(
The old param (passing sigma*2 as an int) were just too confusing
coming from other packages. This new behaviour matches ImageMagick, and
almost everyone else in the world.
A new optional param lets you set the minimum amplitude as well.
