265fb2a825 improve colourspace guessing in icc 
icc_transform does a better job of guessing the colourspace of an image -- if
the colourspace has not been set (generic multiband), it'll look at the
image bands instead and guess from that

Merge pull request #960 from lhecker/master 
Fixed deadlock in vips_cache_drop_all if vips__cache_dump is true
 2018-05-06 17:13:51 +01:00

80a0a24cfa Fixed deadlock in vips_cache_drop_all if vips__cache_dump is true 
Both vips_cache_drop_all and vips_cache_print acquire vips_cache_lock
on entry, but vips_cache_drop_all calls vips_cache_print internally if
vips__cache_dump is true, leading to a deadlock situation.
This commit solves the issue using one further level of indirection
and a new vips_cache_print_nolock function.

d3439f4d49 Fix wrong value for VIPS_FOREIGN_PNG_FILTER_ALL 
The value is derived by oring all the filter flags:

    0x08 | 0x10 | 0x20 | 0x40 | 0x80 == 0xf8

The value was also checked against PNG_ALL_FILTERS in png.h.

load a toilet-roll image ... of course we should test depth as well.

c410dc2db8 add format option to magickload 
Some magick coders (eg. ICO) don't sniff the filetype from the data, so
when you try to load from a string, imagemagick is unable to pick the
right decode path.

Add a @format option so callers can hint the filetype.

d1dd41a21f strict round down on jpeg shrink 
libjpeg rounds up on shrink-on-load. In some cases this can leave a dark
line along the right and bottom edge, since it only contains (for
example) 1/4 of a pixel of data.

This change adds a crop after jpeg load so that only complete pixels are
output.

06802e4110 use O_TMPFILE, if available 
If O_TNMPFILE is available, use it. This is a linux extension that
creates an unlinked file, so it'll be closed by the system when the last
associated fd is closed.
