John Cupitt 3837497613 threaded tilecache could deadlock
in threaded mode, tilecache could deadlock if the downstream pixel
source raised an error

senario:

	- thread1 starts working on tile A and flags it as a CALC
	  (calculation in progress)

	- thread2 needs tile A, sees it is being worked on, and blocks
	  until computation is done

	- thread1 hits an error ... it correctly remarks the tile as
	  PEND (calculation pending), but does not broadcast a wake-up
	  signal

	- thread2 stays blocked!

threads now broadcast a wakeup on tile error as well as on tile success

Thanks to Todd Patrick

John Cupitt ee2b1f71ce better option parsing for "vips"
The vips driver program was parsing options in a single pass. This
failed if an option came in two parts, for example:

	vips --plugin x.plg list

the argument to --plug would be picked up as the action for "vips",
since actions were selected before option parsing

Now we parse in two passes: the first pass picks up options for vips
itself and for the libvips library, then we select the action, then we
parse again, including any options created by the action

John Cupitt 6f22c00df4 NN now rounds down rather than to nearest
nearest-neighbour interpolation now strictly rounds down rather than
rounding to nearest

round to nearest caused strange half-pixels along top/left image edges
during enlargement, and extra 1.5 sized pixels everywhere else

instead we should fix the thing that round to nearest was supposed to fix by
adding an extra pair of params to the affine transform which displace in
input space (dx/dy displace in output space)

John Cupitt 1abac4018a better enum arg error message
you now get something like:

$ vips tiffsave k2.jpg x.tif --compression poop
tiffsave: enum 'VipsForeignTiffCompression' has no member 'poop', should be one of: none, jpeg, deflate, packbits, ccittfax4, lzw
2012-08-10 13:54:42 +01:00
John Cupitt 463058c149 note and use res unit on jpg load/save
previously, jpeg save always used pixels/inch and jpeg load converted to
vips pixels/mm

now on jpg load the image's res unit is recorded in
VIPS_META_RESOLUTION_UNIT, and on jpg save the res unit is set from
VIPS_META_RESOLUTION_UNIT (or defaults to inches).

you can now copy a cm-preferring tiff to a jpg and the unit is preserved

John Cupitt a9c7a36670 be more cautious enabling tiff ycbcr

John Cupitt 73f8263286 sequential can now skip ahead
vips_sequential() no longer bans all non-seq access, it just bans
rewinding --- if you ask for something some way ahead, it reads and
throws away pixels

this means VipsExtract and VipsInsert can now be seq: they will read and
throw away any stuff they don't need
2012-07-14 12:13:58 +01:00
John Cupitt 25ad2b7a53 turn off seq mode in vips7
the new sequential mode readers for tiff/jpg/png were not working well
from the vips7 command-line: they either decompressed twice, or handed
over a sequential mode image

it should now work as well as it did pre-seq.
2012-07-12 09:05:14 +01:00
John Cupitt 643dc28950 turn on seq mode automatically in cli
cli operations turn on seq mode automatically when they can

vips_operation_get_flags() added: lets you attach a set of flags to an
operation

flags for now are "nocache" (replacing the old nocache system) and "seqential"

if vips_object_set_argument_from_string() from string sees "seq" flag on the
object for which it is setting the arg, it enables sequential mode

all operations which can run sequentially have been tagged

the operation printer knows about flags and can display them
