45eaaf4178 Spandspi's FAX engine now gives separate size and resolution information about 
the images on the line and the images in the file. The ties in with the recent
addition of image resizing and flattenign for colur images.
mod_spandsp has been changed to make use of the additional information.

c6c03827b8 T.31 now has basically functional T.38 mode - needs more testing, though 
Various modules which lacked routines to get at the sub-structures now
have them.
The tests have been tweaked so they only access internals where essential.

dfce47f26d Relaxed the constraints for declaring a clean end of call on FAX receive. If we 
get an EOP, we no longer worry whether the final stages tidy up. This helps
tolerate the increasing number of VoIP calls which hang up before the audio has
flushed down the line.

A few little cleanups.

831e5dd4d9 Add image squashing feature to the FAX engine so a superfine image or fine 
image can be sent to a machine which has those resolutions inhibited.

cc73cb6544 Some tweaks to spandsp tests. Make spandsp write TIFF files more like the 
TIFF/FX spec says, even though no software seems to care.
 2012-09-07 00:41:41 +08:00

1603dc70e2 This should have moved us from tiff-3.8.2 to tiff-4.0.2 . The windows builds 
will need rechecking.

7b9e4ff674 Various updates to spandsp tests 
spandsp logging now passes an opaque pointer to the logging routine, to
increase flexibility. Right now the pointer is set to NULL in all calls.

4a7bbf4ec6 Another round of tweaks for spandsp. There should be no functional changes, 
although quite a few things have changed in the test suite
 2011-07-02 21:16:52 +08:00
Steve Underwood
d30e82e226 Numerous little changes to spandsp that haven't been pushed to Freeswitch for a 
while. The only big changes are a majorly rewritten V.42 and V.42bis which are
now basically functional.

ccbee25641 Added some new files for spandsp 2010-07-25 03:43:53 +08:00
Steve Underwood
f029f7ef7c Moved spandsp to a more recent version. A huge number of little changes occur here, as recently spandsp 
lost all the $Id$ entries the source files had for the dark old days of CVS
 2010-07-25 03:29:44 +08:00

01052800c7 A typo fixed in the OKI ADPCM codec 
The V.17 modem has been modified, so it will not clear the most recent
saved AGC value if long training is requested.
The T.38 gateway codec now has fillin implemented properly

Steve Underwood
f87bf812e7 Tone generate modified to export the descriptor creation and deletion. 2010-06-07 00:33:46 +08:00
Steve Underwood
bc13e944c6 Changes to the signaling tone detector to detect concurrent 2400Hz + 2600Hz 
tones. This passes voice immunity and other key tests, but it bounces a bit
when transitions like 2400 -> 2400+2600 -> 2600 occur. Transitions between
tone off and tone on are clean.
 2010-06-06 22:24:20 +08:00
Steve Underwood
3e30434a0c Fixed a typo in spandsp's msvc/inttypes.h

proceed with his signaling work.
