John Cupitt 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

John Cupitt 7a91eaa583 tiff save converts for jpg in jpg mode
when jpg compression is on, tiffsave now converts the input image for
jpg save ... previously, it would try to send a tiff-formatted image
(eg. perhaps with an alpha channel, or float data), which would fail

John Cupitt dbbd2850a1 better max_alpha default

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 c2d1de9a26 allow mixed zoom and shrink in resize
vips_resize() now allows >1 on one axis, <1 on the other ... previously,
although you could have non-square ratios, you couldn't mix zoom and
shrink

John Cupitt 23eaf93867 fix build with graphicsmagick
GM is still using the old page interface of subimage/subrange, IM has
deprecated that in favour of scene/number_scenes

we were accidentally just supporting the new IM system ... this change
adds support for GM as well, plus a configure test to pick one

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 f58190bccd tag non-int rgb tiff as scrgb
Photoshop uses 0 - 1 and no gamma for float RGB, so we tag float /
complex RGB tiffs as scRGB

thanks Murat

we were getting occasional memory access problems in nohalo and vsqbs
interpolators ... the previous fix was not enough

version bump
2016-03-24 16:06:31 +00:00
John Cupitt e8b5cb6c23 add VIPS_COUNT_PIXELS, overcomputation tracking
added VIPS_COUNT_PIXELS(), use like this:

	static int vips_shrinkh_gen( VipsRegion *or, ... )
	{
        	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

John Cupitt 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
