[UFRaw-Devel] Seeing zipper artifacts with X-T1 (x-trans) raw files

[Omari S. <xs...@xs...>]

Howdy, y'all

I'm planning on picking up a Fuji X-T1 soon, and so I'm trying to figure 
out what my workflow will look like.

So, current state of affairs:
I downloaded this as a test file:
http://img.photographyblog.com/reviews/fujifilm_x_t1/photos/fujifilm_x_t1_11.raf
 From here: http://www.photographyblog.com/previews/fujifilm_x_t1_photos/

I have installed the latest dcraw and the latest ufraw from Debian's 
unstable repository:
$apt-cache policy ufraw
ufraw:
   Installed: 0.19.2-2
   Candidate: 0.19.2-2
   Version table:
  *** 0.19.2-2 0
         500 http://mirrors.usc.edu/pub/linux/distributions/debian/ 
unstable/main amd64 Packages
         500 http://mirrors.kernel.org/debian/ unstable/main amd64 Packages
         100 /var/lib/dpkg/status

$apt-cache policy dcraw
dcraw:
   Installed: 9.19-1.1
   Candidate: 9.19-1.1
   Version table:
  *** 9.19-1.1 0
         500 http://mirrors.usc.edu/pub/linux/distributions/debian/ 
unstable/main amd64 Packages
         500 http://mirrors.kernel.org/debian/ unstable/main amd64 Packages
         100 /var/lib/dpkg/status


WHAT HAPPENS:
If I try to open the sample file with ufraw, ufraw segfaults.

If I try to open the sample file with dcraw, it works fine and spits out 
an image

I then compiled the CVS version of ufraw.  If I try to open the sample 
file with the CVS ufraw, it opens, but I see zipper artifacts.  I'm 
confused, though, since dcraw.cc has
#define DCRAW_VERSION "9.20"


So first things first, how do I get rid of the zipper?

Beyond that, it looks like everything other than full-res has a strong 
color cast (Green, in my case).  I presume that is the issue mentioned here:
http://sourceforge.net/p/ufraw/discussion/434060/thread/99c10c54/#1539

I note that dcraw's half-scale output works fine.  i.e., the following 
commands produce images that appear identical, but have different scales:
$dcraw -v -T -w    fujifilm_x_t1_11.raf
$dcraw -v -T -w -h fujifilm_x_t1_11.raf
