[hugin-ptx] Problems with PNG images on 2018.0 on FreeBSD

[Greg 'groggy' Lehey]

I've just received a bug report on Hugin 2018.0.0.5abfb4de7961:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228547

It seems that this package can't process PNG files.  I've checked and
confirmed, and also that it does appear to run with the Microsoft
package downloaded from the web site (also 2018.0.0.5abfb4de7961 built
by Thomas), though I can't get this one to display the
fast panorama preview.

Looking at the port, I have changed almost nothing since release
2016.2.0.  About the only difference is that I removed support for
autopano-sift-c, which is clearly not an issue here.

I suspect that the problem is due to changes in support libraries that
are beyond my immediate control.  Before I go searching blindly, can
anybody suggest where I should be looking?  What library handles PNG
images?

Also, any idea why I can't get the fast panorama preview on the
Microsoft version?  The buttons are greyed out, and I can't select
them.

I've run into similar problems on other platforms, but I haven't found
the details yet.

Somehow there's more to this problem than you have reported.  Can you
go into more detail?  Also, what happens if you create the temporary
directory?

OK, done, tested, committed to the FreeBSD repo:
/usr/ports/graphics/hugin.  The package will take a day or two.

This breaks POLA.  The tarball for 2017.0 was called
hugin-2017.0.0.tar.bz2.  Does the project intend to truncate the name
from now on, or was this an oversight?

One is enough.

I disagree.  At the very least, it is a conscious decision to make
Hugin less portable.  From memory it was because one part of the
documentation builds differently from the rest, and if it is built in
the source directory, it will fail the second time.  The rest of the
documentation builds correctly, so there's clearly a solution.  But
you decided "don't do that, then", rather than fix the bug.  Before
this, things worked with no problem.

I thought you might mean directory when you say folder, but clearly
we're not talking about the root directory here.

> In the source dir

This is not the way the FreeBSD Ports Collection works.  Summarizing
(this is not what you actually do),

  cd /usr/ports/graphics/hugin
  mkdir -p work/hugin-2018.0.0
  cd work/hugin-2018.0.0
  tar xvf /usr/ports/distfiles/hugin-2018.0rc2.tar.bz2
  cmake
  make

This is a design decision.  It works for 25,000 ports, and it will not
change for one package that doesn't want to build in its own tree.

I can work around this bug by patching the files.  From
/usr/ports/graphics/hugin/files/patch-CMakeLists.txt:


   --- CMakeLists.txt~  2016-01-24 20:16:54.0 +1100
   +++ CMakeLists.txt   2016-02-29 14:04:08.376365000 +1100
   @@ -2,11 +2,6 @@
# require at least cmake 2.8

   -message(FATAL_ERROR "In-source builds are not allowed.")
   -endif()
   -
if(COMMAND cmake_policy)
  cmake_policy(SET CMP0003 NEW)
endif(COMMAND cmake_policy)

But that's tacky.  There are two obvious ways to handle the problem:

1 (preferred): Fix the build issue.  If you have lost track of it, I
  can dig it out.
2 (tacky):  Put a conditional round the commands in CMakeLists.txt to
  not make the check when built with FreeBSD.

The bug with "in-source builds are not allowed" is still there.  Apart
from that it builds under FreeBSD.  It would be nice to finally get
this fixed.

That's debatable, but I'm not talking about options.  If somebody
wants the "simple" option, and the fast preview window is disabled,
then enable it.

No, because I don't use the option, and it's not relevant.  This claim
also seems to contradict the explanation above.

No, as a user you need to do nothing.

Try to put yourself in the position of a beginner who doesn't
understand this stuff.

I suppose you mean:

  There are two possible causes for this.

 Cause 2: you have disabled the fast preview window during the

This seems to violate POLA.  Wouldn't it be possible to allow

I suppose you mean JPEG.  It's an option in both save menus.  Just
select it.  You can also set JPEG as default in Stitching preferences.

Or am I missing something?

Please don't post images here.  It also doesn't help: what people

Step back a bit, and you'll get more out of this exchange.  I don't
understand your use of @ signs, but they're out of place here, and
you've lost your context.  Let's try again:

As I said,

So it's for creating HDR images.

No, it means that the script won't work for you.  You will have more
work ahead of you.  Assuming that you don't write Microsoft scripts on
a regular basis, the easiest would be just to type in the commands.
Assuming you have three images view-1-1.jpeg, view-1-3.jpeg and
view-1-3.jpeg (what gets called FILES in the script), and you want to
create an output file view-1.jpeg (called RESULT in the script), you
could write:

   nice align_image_stack -a view-1-tmp view-1-*.jpeg
   nice enfuse -o view-1.jpeg view-1-tmp*

You'll then need to remove the -tmp files.  Of course, if you can find
a way to write a script, this will greatly simplify your life.

Re: [hugin-ptx] Full Dynamic Range HDRi Problems

It would be interesting to see how you do this.  I create HDR images
on a regular basis with a script that you can find at
http://www.lemis.com/grog/src/HDR

It's relatively long, but the payload is at the end:

  nice align_image_stack -a $TMP $FILES
  nice enfuse -o $RESULT $TMP*

It should work essentially "as is" on most systems, but not Microsoft.

You mean you take a single image for the nadir?  That shouldn't be a
problem.

OK, I've taken a look at the two "Fails" images, and yes, cpfind fails
silently for me too.  I tried it with panomatic, and that works.  I've
stitched an 81 MP panorama from them, which you can find at
http://www.lemis.com/grog/tmp/Fails.jpeg

So yes, it looks as if this is a bug with cpfind.  For the time being
you can work around it by using panomatic.

Thre are two steps, of course: stitch the panoramas and merge the
images.  You're doing in that sequence.  I do this regularly in the
opposite sequence: first merge the individual views into HDR images,
and then stitch them.  This gives the advantage that you can use the
individual views independently of the panorama, and it should also
solve your problem.

No, that's not the problem.  It would probably be a good idea to
rotate the images, if only to make it easier to understand them, but
Hugin doesn't make any assumptions about orientation.

The real issue is that the images are so similar that they're
confusing the control point detectors.  You will probably have to
identify them manually; I'd suggest picking on cable sockets.  There
are tutorials on the web site that explain manual control point
settings, but be careful: some of them are somewhat out of date.  If
you can't work your way through them, come back again and we'll see
what we can do.

Sadly, no.  I've added a little bit to the Usage function, but it
basically just says "don't use the -g option".  It should work on any
Unix, Linux or Apple machine.  Ensure that the x bit is set (it should
be), then just run

  $ ./HDR

and it will tell you

  Usage: /Photos/Tools/HDR [-g count] result component-images
 -g count: merge in groups of count imeage, requires 'by' program

If you're using Microsoft, you will have to get hold of a shell, such
as Cygwin, but that's a pain.  Probably it's easier to look at the
payload, just the last few lines.  You need to define a source
(FILES), the files you want to merge, and and a result file (RESULT).
I define a temporary file set TMP as $RESULT.tmp.  With that:

  align_image_stack -a $TMP $FILES

This creates a set of intermediate files with names starting with
$TMP.

  enfuse -o $RESULT $TMP*

This takes the intermediate files and merges them into RESULT.  You
can then remove the $TMP* files.

This is what I do, except I use enfuse.  See
http://www.lemis.com/grog/src/HDR for my script.  You could also do
this with TIFFs instead of JPEGs.

I've tried this in the past, with no obvious advantage.  The advantage
of the first way is that you have finished HDR images that you can use
by themselves if you want.  I sometimes do this.

I use fisheye lens a lot, and I've never done any distortion
optimization, but I've also never run into issues like this.  In
addition, the vertical field of view suggests that this isn't a
fisheye.  Let's see what Liz says.

That looks strange, not just because of the ghosting.  It looks as if
you haven't blended at all, just overlaid multiple images.  It's also
interesting that you've covered an angle of more than 360°.

My guess is that you haven't used the correct procedure.  Could you
explain how you did it?  It might be helpful to put up the source
images.  Don't strip the EXIF data.

Unrelated, but possibly helpful: for panoramas with such a wide range
of illumination: try HDR techniques and stitch the resultant images.

I'm tracking these releases on FreeBSD, and they work modulo this
reported problem with the package refusing to build in the source
tree.  If anybody wants a binary package, please let me know.

It would have helped to say exactly where.  I can only see two of
them, one vertical and one going off at an angle to bottom left, round
the centre of the left-hand flower, and they're only visible at
maximum magnification.

This looks to me like an artefact of the stitching.  How did you do
it?

It would be nice to have a single archive file, but if you have
difficulty with that, dropbox will be OK.  Expect others to have a go
too.

It might be a Microsoft problem.  On my (FreeBSD) machine it took
about 2 minutes.

But that doesn't help much.  align_image_stack can't handle changes of
perspective, and the result is useless.  You need to take all the
images from the same place, preferably mounted on a tripod.

> Then I tried to just load all the images into Hugin and click Align,
> but that didn't get me very far.

I tried that first.  There's also a question of constant exposure.  In
this case the images are exposed between 7.9 EV and 12.6 EV.  That's
fine for align_image_stack, but not for the control point detectors.

What do you want to do with the images?  Just line them up so that
they all line up?  That will work if you take them from the same
position.  There should be a tutorial on the web site, but it seems to
be hiding.

Hmm, interesting.  I've seen this kind of effect before, but I forget
why.  Could it be that you have used different exposures for each
image?  It could be that enblend is having difficulties adjusting the
exposure.

The other thing you could try would be a few more overlaps.

f/2.8 is an aperture, not a focal length.

No, that's a crop factor, not a focal length.

No, forget the f/2.8.  It's not relevant here.  Check your lens again
and see if you can find a real focal length, and the you can use 5.57
as crop factor.

If you can't find a focal length, and since it's a 170°, set the focal
length to 15 mm and crop factor 1.  That should be close enough for
the control point detectors to align the images.  If it's a 360°
horizontal panorama, they will then calculate a more accurate focal
length, which in my experience is not always what the manufacturer
complains (for example, I use an Olympus 8 mm lens, crop factor 2, but
the control point detectors are unanimous in saying that it's really
7.7 mm).

> Should I use 5.57 as the focal length in Hugin with a multiplier of 1?

No, definitely not.

I've read what the others have written, but there still seems to be
something missing.  As they say, there are no EXIF data, so Hugin asks
for a focal length.  But you don't mention that.

Most mobile phones have a relatively wide angle lens.  I specified 30
mm, crop factor 1 for these images, and they aligned perfectly.

> I am running 2016.2.0 on Windows 10 x64.

There has been some question about this.  But as Stefan says, maybe
it's your configuration with a hangover from older versions.

That's really a question for Tourweaver.  The web page and videos
aren't very helpful, but the panorama display programs that I know
usually want an equirectangular projection, which is simple to produce
with Hugin.  If that doesn't work, you could try some of the others.

It's hard to tell from the results.  Where are the original files and
the .pto file?  FWIW, I take many panoramas with an 8 mm fisheye, and
they align and stitch very well, so it's quite possible.

> I tried with different type of lens: normal, fish eye circular, fish

One of the fisheyes.  I haven't seen a difference, but the question is
whether your lens covers the complete sensor, or whether the corners
are empty.

I think I've seen one, but I'd have to search.  Let's see your images
first.

I'd be interested in looking, but downloading 23 files by hand or

As a data point, clang 3.4.1 works fine, though it finds many things
to warn about.

More to the point, how is this information encoded into the EXIF data?
I'm pretty sure there's nothing in the standard.

[hugin-ptx] Status of autopano-sift-c?

[Greg 'groggy' Lehey]

I've just had a bug report against Hugin on FreeBSD
(https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214391) which
appears to be related to autopano-sift-c.  Comments welcome.

I've been looking for the sources for this program, and the newest I
can find are version 2.5.1 from October 2009.  At
https://sourceforge.net/projects/hugin/files/autopano-sift-C/ I get
the message

  Looking for the latest version? Download hugin-2016.2.0.tar.bz2 (10.4 MB)

But there are no sources for autopano-sift-c in that tarball.

So what is the status?  It appears to be unsupported, and my
experience with it suggests that there's nothing it can do that
panomatic or cpfind can't do better.  Is it time to remove it?

Well, it's certainly an interesting error message.  Do the details
help?  Are you mixing JPEG and TIFF images?  If so, what happens if
you start with only the TIFFs, maybe only a couple at a time?  And
where did the TIFFs come from?

There are a number of techniques described in the tutorials.  But this
is a particularly easy panorama, and it shouldn't have happened.  Have
you set the entrance pupil correctly?

I think it's because there are too many pixels.  This means that the
resultant image is bigger than Google drive will accept.  You can
downsize it externally, or you can set a smaller size in the Stitcher
tab.

It's not said that another hoster will have the same problem.

That's maybe jumping to conclusions.  It's fairly certain that icpfind
can't find the PATH environment variable using the wx interfaces; it
doesn't mean it wasn't set, nor that the rest of the environment is
missing/inaccessible.  I'll continue looking, but it's not a high
priority for me.

Thanks for following up on this.  I think I've done as much as I can,
so I'll leave it to you.  A couple of thoughts:

> And finally: I still don't know what file system runs out of space.

Yes, I've asked several times for details on this, but none were
forthcoming.

I think it's reasonable to assume that Michael was partially following
my instructions by removing the temp directory specification, so it's
possible that the files were being written to /tmp or elsewhere on the
root file system.  But there's no way to know without the information
I asked for.  As you observer, all the df output he sent shows plenty
of space free in both directories, at least because they weren't done
concurrently.

Quite possibly there is an issue here with enfuse.  My guess is that
it really does write to the temporary directory.  If that's the case,
then setting it to be in /home would probably solve the problem, in
which case the only issue is the bug with the missing PATH variable.

> unless you have bracketed shots.

I suspect this is a problem with the Assistant, which frequently
offers this for what appears to be no good reason.  It doesn't happen
if you go via the Stitcher tab.

I'm prepared to blame libraries for lots of things, but I can't think
of a scenario where one could cause this kind of problem.  Still, I've
compared the two ldd outputs (sorted, trimmed path names), and we
have:

OK, that wasn't it, then.  It might still be worth looking at this
towards the end of stitching to see what happens to the "Used" value.

That's exactly what I'm asking you not to do.

If you mean the information you referred to above, definitely.  So far
there's no evidence that anything is wrong with Hugin.

That's possible.  Hugin does not use tmpfile(), but it's not beyond
the bounds of possibility that some library might.

I'm sure that much of your issues relate to the fact that you write
your reply away from what you're replying to.  In case it's my
terminology, that recommendation is to leave the temporary directory
specification empty (default).

OK, these are just the small PTO files, which you showed in more
detail in your other post.

> after stitching:

Is this your comment?  It confuses the issue.  But after stitching
there's nothing left to do.

At least I have the information now, but unless nona or enblend are
hiding something, there's no evidence of any large files being written
to the temporary directory, so you might as well reset the preference
so that you don't have to start Hugin twice.  If you do run into the
root file system filling up again, take a look in the /tmp directory
and see what you can find.  My guess is that whatever the problem was,
it has gone into hiding.

I did specify 'ls -l'.  If you look at those files, I think you'll

We seem to be going round in circles.  I reported this issue nearly a
week ago.  What does it write to the root file system when you don't
specify a temporary directory?

I have now committed the FreeBSD port.  The package should become
available in a day or two.

If you find anything wrong with this port, the correct way to report
it is via the FreeBSD site at https://www.freebsd.org/support.html
You can, however, also contact me.

Where?  Take a look in your specified directory and see what's in

OK, that's interesting.  I thought it once worked for me too.  What
platform and version of Hugin?

I modified icpfind to find what it was looking for.  It had an empty
PATH variable, so it couldn't find the control point detector.  And
yes, I'm still planning to track the bug down.

Good idea, but so far we have no evidence that anything is being
written to /tmp or wherever.  That's what I've been trying to find out
for the last week.

*sigh* I've been through this in some detail.  This is the bug we
discussed some time ago.  Please don't set your temporary directory.
Go to Preferences/Filenames and make sure that "Temporary Dir" is
empty.  If you still get the "Could not find "cpfind" in path."
message, please confirm that you have reset this field and post your
~/.hugin file.

And what files are you writing to /tmp?  Nobody else sees any written
there.  You have confirmed that the logs don't get copied to the
clipboard, but you can still watch the window.  If that's too much
difficulty, try repeating this in a shell window while stitching is in
progress:

  $ ls -lrt /tmp

That should list any newly created temporary files.

Where's that?  When I select the stitcher, I don't get that option.
It's also not in preferences.  I thought it might be related to the
Interface (Simple/Advanced/Expert), but I get it in Simple mode as
well.  Do you not see the window?

When you select "Create panorama" or "Stitch", you get asked for a
name of the resultant panorama.  Then a log window pops up and shows
what's going on.  When it's finished, it conveniently goes away.  Take
a look at
http://www.lemis.com/grog/photos/Photos.php?dirdate=20160918=4
for an example.  Here you'll see it writing to
/photowork/Hugin-build-eureka/ .  My question is what pathnames you
find in your log window.

The documentation says that if you select "Copy log messages to
clipboard" in the Preferences/General tab, you will get log messages,
well, in the clipboard.  That doesn't work for me, but it might for
you.

I don't know many root directories that big.

We (mainly Sean Greenslade and I) discussed this, but the only firm
conclusion was that normally nothing gets written to the temporary
directory.  That's why I asked you:

The fact is that you *have* managed to fill up your root directory,
and so far we have no explanation for it.  It's not beyond the bounds
of possibility that you have another bug here.

You still haven't answered my question about the running out of disk
space.  We haven't been able to reproduce that.

I'm still investigating exactly what happens, but then I will either
report it or submit a fix.

For the record: setting that variable (which ends up in ~/.hugin as
tmpDir=/var/tmp, for example) appears to cause hugin pass an empty
PATH environment variable to icpfind, which then fails.  It's not the
problem of icpfind, which works fine if started directly.  But I
haven't had time to track it down yet.

Unfortunately it was bad advice, leading you to a bug.

That's not important.  The issue is that specifying any temporary
directory invokes a bug whereby hugin doesn't pass the PATH
environment variable to icpfind.  I didn't know this when I wrote (2)
above.  But this means that icpfind can't find the control point
detector.

Read what I wrote above.  It can't.

Yes.  If you can't find the control point detector, you can't run it,
and that happens immediately.

> It isn't even trying.

Would you please try?  As I said:

No, this is in no way related.  This is the way your camera is
reporting them.  The control point detector, once you find it, should
fix that.

I have been able to reproduce this message, clearly with a subtly
different version of wx (see the line number):

/usr/local/include/wx-3.0/wx/strvararg.h(456): assert "(argtype & 
(wxFormatStringSpecifier::value)) == argtype" failed in wxArgNormalizer(): 
format specifier doesn't match argument type

This appears to be the result of a number of issues:

1.  You followed my advice and set the temporary directory path in
preferences/file names.
2.  The "temporary directory path" is really a search path for
executables.
3.  You missed the message "can't find control point detector".
4.  The error message seems to have gone out of its way to be
unclear.  Probably it's reporting an error that occurred as a
result.

Could you please try removing the entry for the temporary directory
and see if you still have trouble?  As I said (thread "hugin shouldn't
stitch in root"):

Not without seeing the images.  Where are they?  Did you take them at
constant exposure settings?

Which version of Hugin is this?  And what's the platform, and where
did you get the executable from?

If this is a 2016.* version, I'm not sure that this is serious.  I
can't reproduce the message at will, but I've seen something similar
at this juncture.  It gave me the option to continue, and when I did,
everything continued normally.

Yes, but this isn't the sort of thing you do when you start off.  I've
just checked and discovered two things:

1.  On a 15136x7568 pano with 20 components (the largest I do), the
intermediate files  took up 550 MB.  It's not clear that your
intermediate files are larger, since there are more of them, but
that could easily mean 2 GB in your scenario.

During stitching, the enblend image grew to about 8 GB, and I
could easily see you heading over the 16 GB in your scenario.  But
that's (virtual) memory, not disk space.

At the end of stitching, total disk space (intermediate and final
image) grew to about 800 GB.

2.  How much space was used in /tmp or /var/tmp?  None at all!  I
don't know where I got the idea that the intermediate files go to
/tmp.  So the question remains: what is getting written to the
root file system in Michael's scenario?  Michael, can you check
next time you stitch a pano.  The log window will tell you what is
being written, and where.  Maybe it's not /tmp at all.

I think we have a disconnect here.  That's what I understand by
"create a (360°) panorama".

That second URL is a very roundabout way of saying the same thing.
But clearly you mean "how to animate a 360° panoarama".  There are
various software solutions, and we discussed some of them a while
back.  See
https://groups.google.com/forum/#!msg/hugin-ptx/2BRtxG3lSM4/MrLhTJedAQAJ
for one discussion.  Cartola (http://cartola.org/360/) does a lot of
this stuff, and may chip in if he sees his name mentioned.

Your URL is interesting, though.  I'll take a look.  My first
impression is that the online view is slow.

Yes, it should.  It also has the advantage of higher resolution.  With
a fisheye lens you get the whole scene in 6 photos.

I think you're about the fourth person to point this out, but I

Michael, have you followed the advice on parallax that many of us have

Others have addressed your probable issues, but I'm still left
wondering what you mean with this suggestion.  Can you elaborate?

The big issue in these images is exposure, both overall and in
relation to each other.  This is part of the reason why no control
points are detected between the left-hand two images.  Another reason
could be the relative lack of appropriate features for control points.
It's not a good idea to have the camera on auto ISO, but it's unlikely
that this could cause significant problems with control point
detection.

> How do I figure out lens distortion? Darktable knows my lens
> including it's distortion. Can I use that information somehow?

Your camera has a raw format (NEF), and that's what you should be
using.  You can probably do this automatically with Nikon ViewNX-i,
available for free at
http://downloadcenter.nikonimglib.com/en/download/sw/71.html.  But I
greatly doubt that distortion is your problem.  If you want to use
Darktable, process the image to correct distortion and feed the output
images to Hugin.

Since this doesn't look like a once in a lifetime, never to be
repeated shot, and you haven't mentioned entrance pupils, I'd suggest:

- Use a tripod.
- If you have a panorama bracket, use it.  Otherwise mount the camera
  on a rail.  It seems that you can get entrance pupil information for
  your setup from
  http://hugin.sourceforge.net/docs/manual/Entrance_pupil.html and
  http://wiki.panotools.org/Entrance_Pupil_Database.
- Use manual focus, manual exposure (check which is most appropriate
  before you start), recommended ISO setting for your camera, and raw
  images.

That will give you the relationship between the entrance pupil (z
axis), but not the x and y axes.

> check out the sample I posted.

What I see there are:

- It looks like a 3 row pano.

- The middle row seems OK.  This suggests that your z axis adjustment
  is good enough.

- The black areas are where you have no coverage at all.  So though
  your coverage may overlap in the middle, it's not overlapping in the
  corners.

- The bottom row has serious alignment issues.  That suggests to me
  that your lens is offset either from the x axis (axis of the main
  rotator), or (more likely) from the y axis (axis of the horizontal
  rotator).  It seems that MCE doesn't get too worried about these
  things, but the Hugin control point detectors don't want to know.
  You could add control points manually, but it would be better to
  address the cause.  Take a look specifically at
  http://www.johnhpanos.com/epcalib.htm (mentioned above) just before
  section 4.

I suspect that you'll get considerably better results next time
round.  If you don't, post the images (original size, with EXIF data)
somewhere and I'm sure a number of us will take a look.

Documentation?  Before going to the trouble of finding a Microsoft

know what advantages it has over Hugin.

These are basically all restrictions compared to Hugin.  But in
itself, these restrictions point to areas for future improvement.

[hugin-ptx] Problems with Hugin 2016.2 rc 1.

[Greg 'groggy' Lehey]

I've just built rc1 on FreeBSD, and I've run into some issues testing
it.  When I start, I get these messages on the xterm:

  (hugin:99873): Gtk-WARNING **: gtk_widget_size_allocate(): attempt to

It's possible that this is behind a number of issues I have had,
mainly with the fast panorama preview.  If anybody recognizes these
messages and can point me to the solution, I'd be grateful.  Otherwise
does anybody have a Microsoft package ("Windows" 7) that I can use to
test the same images?

Thanks in advance

Based on reports I heard about earlier versions, this is an area where
Photoshop was weak.  But as I said, a comparison would be good, and if
there are areas where Photoshop is better, it would be clearly
something to address in Hugin.

Those are two different products, of course.  I don't know the

Last time I heard, no, much worse.  but that was a long time ago, and

If not, because you then have no choice.  If so, Photoshop still costs
an arm and a leg.  If you have Photoshop, why not do a comparison and
report back?

[hugin-ptx] 360 degree pano viewer?

[Greg 'groggy' Lehey]

I used to use SaladoPlayer for preparing and viewing 360° navigable
panoramas, but after a system upgrade it no longer ran, and it seems
that the web site is up for sale, so I assume that's the end of
Salado.  Does anybody have an alternate suggestion?

Information is useful too.  And it's not documented in the canonical
places.

Why?  It seems there is stuff in there which can't be found
elsewhere.  Documentation shouldn't be optional.

I looked there too.  I've looked again.  There's no mention of the
online documentation at
http://enblend.sourceforge.net/enblend.doc/enblend_4.2.xhtml/enblend.html
there or anywhere else in that directory.  It should be there or in
the man/info pages.

I have:

 can build all documentation:  no, because of missing tidy

OK, I missed that one.  I didn't do the original port, and it's
possible that this got missed as a result.  I'll go through the README
and check what else I've missed.

Sorry, don't understand.

I'd suggest that it's more of an attitude problem.  Incomplete man
pages don't help anybody.  There's no reference to some options, nor
to the online documentation.  It also claims that the info pages
(without graphs or images) are included in the info pages.  And I
can't find any reference to the online documentation in the build
instructions or any other file in the top level build directory.  How
did the Microsoft build people find out about it?

No wonder people are confused.

It shouldn't be.  That's what man pages are for.  And the man page
doesn't even mention this combination of options.  I've only just
discovered:

I'd be inclined to install the external version of enblend, whatever
that means.  Otherwise a bit of information on your platform and Hugin
version might help.

Remove the following lines from CMakeLists.txt:

(end of patch)

The background is that if you allow in-source builds, one of the
documentation files modifies itself during the build.  The FreeBSD
always performs in-source builds, and this is a major nuisance.  If
you want to check which file is affected, I'm sure it's fixable.

The FreeBSD compiler (clang) certainly does.  But as you know, I've
had much pain with clang and hugin, and if there's any change to the
C++11 path, it could break something.

I've updated the ports Makefile accordingly, and there seem to be no
issues here.

This is now in the FreeBSD Ports Collection as graphics/hugin.  It
will take a few days for the packages collection to be updated.

At the same time I have deleted the port graphics/hugin-2016 (rc2).

Contact me if you have any difficulties.

The FreeBSD version is available from ports as
/usr/ports/graphics/hugin-2016 (the same location as RC1, which is now
no longer available).  It will take a few days for the packaging
system to create the new version.

OK, I've taken a look at the images.  The first thing that strikes me
is the significant difference in exposure, particularly:

File orig/pict0308-20160306.mrw
Exposure:   1/5 sec, f/5.6, 27/400 ISO

File orig/pict0309-20160306.mrw
Exposure:   1/25 sec, f/5.6, 27/400 ISO

That's very visible in the originals, and it causes problems both with
the control point detectors (I used CPfind) and with blending the
final panorama.  But using 2016.0.0 RC1 running on FreeBSD 10.2 amd64,
I got:

Assistant:
   Images connected by 74 control points
   Error 9.1/23.4

Photos tab
  Optimize Positions (incremental, starting from anchor)
  Images connected by 84 control points
  Error 1.2/4.3

Particularly the second looks very acceptable, though the blending is
suboptimal.  I've put the images up at
http://www.lemis.com/grog/photos/Photos.php?dirdate=20160307=220
(click on each image for larger versions).  The first (pano-1) is done
with the Assistant, the other with the pano editor.  Neither used
vertical line detection, which in my environment proves to be more of
a problem than it's worth.  You'll note that the images are almost
perfectly connected in the second version, while there are significant
discontinuities in the first.

I was about to say "So what's the difference?".  But the answer is
clear: I processed the raw images with DxO, while you used Bibble.  So
I tried with your TIFF images and got results similar to yours:

  Images connected by 73 control points
  Error 10.2/315.1

Looking at the control points, the big deviations are between the
overexposed image and the one to the right, and the control point
detector has been completely confused.  Why this should happen now and
not with earlier versions, I don't know.  And I still got a
recognizable panorama (pano-3).  Comparing it to pano-2, it's clear
that the second image was burnt out in the TIFF version.

That still doesn't explain why I get (marginally) different results
than you, or why I got two different results from Assistant and Pano
Editor.  I've seen similar strangenesses in the past, where the
results depend on how I process the images and what platform they're
on.  But I think your problems will go away if you can repeat the
shooting next Sunday and expose all the images the same.

Yes.  Clearly it failed.

Do I understand correctly that you didn't try it with an older version
of Hugin?  That might be worthwhile.  It would also be interesting to
see where the big errors are (control points window).

Anyway, without seeing the images, it's hard to say.  Can you put them
up somewhere.  From my point of view I'd rather see the raw images,
but compressed TIFF or JPEG might be a better choice for most people.
