Mate is build as a consequence of gnome 2. Current version is based on

Yes, I'm pretty sure :)

When cursor reaches another control somewhere within the main window, 
the edit window looses focus. It should be some control (slider, another 
edit window etc), not a label.


I have standard Mate from 18.2 Mint and proprietary AMD GPUpro video driver.

Are you *sure* you don't accidentally mouseclick right after 3. and before 4. ?

Hello

And the scenario is still working.
1. Select an image in the lighttable mode.
2. Click into the edit window Max size in the export dialog.
3. Move mouse just slightly outside the edit window. It loses focus 
immediately.
4. Type the digit you want. It is recognized as rating for the image 
being selected.


The item 3 is the problematic one. Why does the edit control loose 
focus? One haven't clicked outside the control. A mouse is not 
guaranteed to keep its exact position just after it has been released - 
and it _is_ released to type digits on a keyboard.

I've got darktable cloned from GIT on my HDD. Today I did

git pull

and then

./build.sh

and I got this error

​What can I do to fix it? I'm on Arch Linux (4.13.4-1-ARCH). When I last
built DT after "git pull" about 3 weeks ago​ everything went OK.

Thanks for a reply.

Re: [darktable-dev] Deconvolution and Python framework

Aurélien, this is really interesting.
I saw some output of Piccure+ and (if REAL and not otherwise handled) they
are really interesting!
I hope someone can help you with the porting.

Re: [darktable-dev] Deconvolution and Python framework

[Aurélien PIERRE]

Hi !

Following my work from this Summer, I'm glad to propose my first blind
deconvolution algorithm, written in Python, based on papers from
2011-2014  : https://github.com/aurelienpierre/Image-Cases-Studies

TL;DR :

Blind deconvolution is a technique used in astronomy and microscopy to
deblur pictures based on an estimation of the blur "profile" (SPF for
the geeks). This work on motion blur, focus blur, etc. A commercial
photo software get spectacular results with this technique :
http://relaunch.piccureplus.com/ (although it's not really blind).

My code is a proof of concept which runs now (barely optimized) between
50 and 275 s on a 2 Mpx image.

I'm still looking for some help to port it in a Darktable module, since
I'm not a C developper (or at least some doc). 

Thanks !
