John Cupitt dbbe8b77c1 vipsheader could crash on bad field names

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 2be0b97dce switch to g_warning()_/g_info()
we had vips_warn() and vips_info(), but they are a bit crappy ... switch
to g_warning() and g_info() instead

we were not updating argc in vips.c after all calls to
g_option_context_parse_strv() on Windows, leading to a crash in some cases

John Cupitt 595f18cf64 tiny speedup for vipsthumbnail --linear
use scrgb for working space in vipsthumbnail, was xyz

John Cupitt dbbd2850a1 better max_alpha default
it used to default to 255, now it sniff the interpretation and defaults to
65535 for RGB16 and GREY16

John Cupitt 54d8e4808f restore bandfmt after unpremultiply in thumbnail
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.

Example:

	$ vipsheader Opera-icon-high-res.png
	Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
	$ vipsthumbnail Opera-icon-high-res.png -o x.tif
	$ vipsheader x.tif
	x.tif: 117x128 float, 4 bands, scrgb, tiffload

This change makes it note and restore BandFmt aropund pre/unpremultiply.

John Cupitt 2c646a02e4 better jpeg autorot
jpeg write is more careful about removing exif tags that have been
removed from the image metadata

it failed previously if there were multiple Orientation tags
2016-04-13 08:39:29 +01:00
John Cupitt 8fb146029c more tuning of vipsthumbnail

John Cupitt ad7ddc4f24 more vips_resize() tuning
now we have better tuning for the anti-alias blur, we can increase the
amount we shrink by and reduce the amount we affine by

this gives a noticable speedup
2016-03-01 11:19:30 +00:00
John Cupitt 19a838470b add webp shrink-on-load

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 346a9e70c0 remove --disable-cxx flag
it was getting too hard to support :( automake now generates libtool
lines before configure runs, so it can't know we don't want a C++ link
