John Cupitt e19f9ea0b3 working!

John Cupitt 2620f3b8c9 allow non-square vips_resize()
in a very crude way
2015-11-19 17:09:18 +00:00
John Cupitt 8506ff13a6 try to improve vips_resize() quality
small improvements to vips_resize() quality:

* turn down the anti-alias filter a little so we don't smudge out texture
* don't do the final sharpening pass if we skipped the anti-alias filter
* fix a >/>= mixup which meant we didn't sharpen for small resizes

John Cupitt 3b32200cc1 sizealike() and friends elide completely
sizealike() / formatalike() and bandsalike() used to just vips_copy() if
the image didn't need any changes ... this was fast, but left a
vips_copy_gen() in the pipeline, wasting a lot of space on the C stack
during recursion.

They now vanish completely if the image is already in the right format.
Since we call them before most image processing operations, and
often all three of them, this saves a lot of C stack, more than x2 even
in simple cases.

There might also be a measureable CPU saving if the operations are very
simple (eg. insert).

John Cupitt d94a2807c9 smarter cache sizing for vips_resize
see comment in code, should now account for max delay possible
2015-11-11 10:23:50 +00:00
John Cupitt 66fe338d36 better alpha handling for tiff save
the tiff saver was writing all five-band images as CMYKA, even if they
were tagged as srgb ... it now follows the interpretation tag and will
write many alpha channels instead

see https://github.com/jcupitt/libvips/issues/348

John Cupitt 2b46b7e889 many more const decls
ruby gobject-introspection is quite fussy about needing a lot of const
declarations ... these changes help vips_image_matrix_from_array()
appear in Ruby
2015-10-23 11:45:11 +01:00
John Cupitt 64d081e726 return default value for unset props
we used to issue a warning and return early, but this can leave garbage
in the *value pointer, I think

ruby gobject-introspection will walk object props during GC and can see
state inbetween init and build when not all objects have been given a
value ... we don't want these warnings

John Cupitt fbe321eebf change exif names argh
change exif names again: we were storing under @title, but that's both
subject to i18n, and unlookupable in libexif

we now use @name, which is not subject to i18n and can be searched for
... this will break most code which expects certain exif tag names

also, when we update exif, allow any tag, not just updates to existing
tags, see:

have to have gobject-2.0 in the link line of things like:

	g++ -g -Wall hello8.cc `pkg-config vips-cpp --cflags --libs`

John Cupitt 6e2135d8b5 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.

John Cupitt 384a5e05dc change parameters of vips_gaussblur()
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.

John Cupitt 325f3b9451 dzsave will write a zip file

- no way to pick a container format, always zip
- needs testing
- examine memuse, how well do we work for large zips
- can we make a zip over 4gb?
