[hugin-ptx] Question about Lux and PTO files

[David W. Jones]

In my testing here, it completely ignores crop settings in the PTO file. 
It seems to me that would severely restrict usefulness, particularly in 
situations where you have a large panorama with a small crop area.


Ideas?

You can always simply look at the lux documentation, where all mouse 
gestures and key commands are explained in great detail - the section 
in the README is titled 'User Interface'. Find the documentation here 
.

Yes, the famous RTFM.


The UI is made so that you can interact with the view with gestures 
and usually don't have to use the menu, unless you need to change 
settings or do 'something special'. Once you get the hang of it,

Then it's not nearly intuitive. But it is different.
it allows you to view (and present) your images fluidly, doing most of 
the view control with the mouse, and the occasional keystroke. 
Admittedly, performance with touchpads is not optimal, so if you use 
lux on a laptop, it's a good idea to connect a physical mouse.
I do use a physical mouse. I also have a graphics tablet on the laptop. 
I don't use the touchpad, I really, really, really don't like them!
I recommend you read the docu - some of the mouse gestures are quite 
specific and hard to figure out by trial-and-error, e.g. the 
brightness and zoom level gestures.

Zoom in and out using my mouse wheel works exactly as expected.

Just grabbed it and tried it out. Works fine on stock Bookworm. Thanks!

Re: [hugin-ptx] lux 1.2.2 released

[Maarten Verberne]

had some time and did some testing comparing enblend/nona vs lux.
these results are from the same system with the same set of images, 
results on your system are different ;)


image quality was good, sometimes a bit better, sometimes a bit less, 
depending on lighting conditions that make the need for blending important.


i didn't like that lux out of the box worked with a preview full screen, 
it made it impossible to use the system (without a 2nd monitor) while it 
was running.


while i run nona -g(pu) this only has an speed advantage if i start more 
than one script, i gives the system time to sync those operations and 
creates more headroom on the cpu for that 3rd script running.


i set one instance Nona -g/Enblend/Exif at 100, the other values are 
related to that.
Lux/Exif is just a bit faster than 2 instances of Nona -g/Enblend/Exif 
running the same set.

Sorry I can't really help with that - I was hoping that the AppImage would 
run just about everywhere, but there seem to be limits... Sometimes lux 
starts flashing on start-up if the screen extent is unexpected, and my code 
just re-tries until it gets what it wants, which may not be the right 
approach in every case. I do that to circumvent buggy behaviour in gnome 
which occured after the switch to wayland - I reported the problem, but 
there was no echo, so I had to program around the bug...

Can you please try and start lux in a window to see if that maybe avoids 
the flashing? just try

lux -W

This is also easier to shut down if the controls don't work anymore.

My other laptop is an aarch64 laptop and the deb and App image do not run 
on it either as they are intel x86_64.


That's correct. On macOS, you can run the i86 build via rosetta, but on 
other OSs, there are no handy emulation layers which instantly kick in 
automatically. But it would be interesting to see ARM builds for other 
platforms! You know that the build is quite straightforward for Linux, so 
if your ARM boxes run linux, it might be as easy as clone the pv repo, cd 
pv, mkdir build, cd build, cmake .., make. I recommend installing highway 
as a build-time dependency. On ARM it should make a big difference. Usage 
of ARM-specific build toolchain should happen automatically - the cmake 
build detects the host CPU. Packaging as debian package is now quite 
straightforward; all you have to do is to tell cmake to pick the 
appropriate package generator. The variables for the generator are already 
in the CMakeLists.txt. you specify the generator like this:

cmake -DCPACK_GENERATOR=DEB

after that, just say

make package

and cmake should produce the debian package. That's how I made the debian 
package I just uploaded. Apart from not being signed, it seems to fit in 
well, and it's much smaller than the AppImages! It also saves me the 
headache of having to include third party copyright info for all the shared 
libraries which the AppImage generator I use does not find automatically... 
but, hey, I want to see users from other distros use lux as well, hence the 
AppImage approach.

If you can produce a viable debian package for Linux on ARM, I can upload 
it to my downloads page. I think we did that some time ago when you were 
building lux on your RasPis.

I just wanted to report the same. Also on Debian Bookworm.
I will await the new .deb package.
The AppImage does not run on my Chromebook with beta linux, which is the
reported debian bookworm by the way. It starts flashing and completely
blocks everything. But that could be because it is linux running in a
sandbox on ChromeOS.
My other laptop is an aarch64 laptop and the deb and App image do not run
on it either as they are intel x86_64.

Bye,
Harry

I uploaded a debian package 
 for debian 12 
stable. It might be usable for other debian-based distros.

Thanks, downloaded, tried it. It installed over the 1.1.6 that was there 
before. Trying to run lux in a terminal gave me this:

lux: error while loading shared libraries: libexiv2.so.28: cannot open 
shared object file: No such file or directory

Bookworm comes with libexiv2-27. I have that installed. I guess the 
libexiv2 version your package is looking for is -28?

Ah, thanks for pointing that out! I used a local build of libexiv2 v. 28, 
and the dependency slipped into the package. Using libexiv2 v.27 is okay, 
but there are some (annoying) API changes with v.28 and switching back to 
v.27 requires some finessing in the build. I'll see to it that the 
dependency is set to v.27 and rebuild and upload the package. Thanks for 
testing!
