Steve Underwood fc7a74905b Various little memory leak possibilities in spandsp sorts, and the spandsp

received as we queue a retry, causes the retry frame to remain queued in the
HDLC entity.

Steve Underwood c09dec0de1 Fixed jaggies in image resizing. 
Split naming of T.81/T.42 type JPEG from normal JPEG. This is in preparation
for allowing the selective output of normal JPEG (like most people want)
and the T.81/T.42 type you might want for forwarding as T.37

Steve Underwood 365fc08719 Changed spandsp from using TRUE and FALSE to using C99 true and false. It seems 
like the quirks we used to get using those with C++ have gone away.
 2013-08-08 21:40:28 +08:00
Steve Underwood df669f700a A cleanup of FAX image size/resolution matching accuracy. Squashing of bi-level 
images should now be correct. This is now close to supporting grey scale and
colour.
 2013-08-06 02:38:06 +08:00

 2013-03-14 05:04:43 +08:00
Steve Underwood 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.
 2013-03-10 20:55:21 +08:00
Steve Underwood 1d289b3617 Chnaged T.30 x-rex, y-res, width vetting to be more rigorous.

Steve Underwood 560e70f27d Some minor tweaks to T.30 page handling 2013-02-25 22:48:12 +08:00
Steve Underwood 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.
 2012-11-14 21:53:17 +08:00
Steve Underwood 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.
 2012-09-14 00:24:19 +08:00
Steve Underwood 5f12c3dc1c Improvements to T.4 end of image handling, and the related tests.

 2012-08-11 18:32:00 +08:00
Steve Underwood 3ae2bdf4aa Improvements to dithering down colour and gray scale images to bi-level 
images, for images with different illuminants.
 2012-08-07 22:34:32 +08:00
Steve Underwood e523076274 FAX T.6 decompression fixed for images with black in the last pixel of lines. 
Colour and grey images can down be dithered down to bi-level images for transmission as faxes.
More movement towards T.42 support
