@David_Tschumperle the Manjaro build in the link above is still from march 24th…
Yes sorry, I forgot to upload the package. This should be done now.

It’s ok now, all the packages have been updated.
Great news : Sébastien has finally released the source code of G’MIC-Qt on github, licensed under GPL3.
Do not hesitate to play with it and report any weirdness ! Link : GitHub - c-koi/gmic-qt: G'MIC-Qt is a versatile front-end to the image processing framework G'MIC.

Hello Sébastien,
Yes, I’ve just forked the repo and started to hack on it to allow compilation for GIMP 2.9 :
This is a temporary repo (Seb is on vacations this week), but it should work right now.
I think Seb will merge the changes I’ve made on next week.
Thanks David,

I have a fairly recent Gimp 2.9.5 (commit ccc4b58), maybe it’s the problem.
You should try replacing GIMP_LAYER_MODE_HSL_COLOR_LEGACY by #define GIMP_COLOR_MODE GIMP_LAYER_MODE_HSV_COLOR_LEGACY.
I suspect your Gimp 2.9 API to be a bit older than mine, and this change has been made in the source code recently.

That worked, David, thanks! the qt plugin compiles and runs fine on Manjaro.
I’ll try to update Gimp later, and revert the change you suggested.
Hi David,
stand alone version works great, but I get an error with qmake HOST=gimp
Project ERROR: gimp-2.0 development package not found
I have installed libgimp2.0, I don’t know what I’m missing.
Also gmic_qt is installed on the gmic_qt directory, is there a way to specify the target dir? I try qmake HOST=none TARGET= and it didn’t work
After a few tries I found that is DESTDIR, not TARGET…
You need the gimptool-2.0 binary installed as well as the GIMP include files.
On Ubuntu, the needed package for that is called libgimp2.0-dev. You have to find something similar in your distro.
I have that too. I did a fresh install on a VM and it work fine, so I guess is a problem with some libraries, but I’m not sure what can it be, I’ll look into that. And if everything fails I can always do a re-install.
Release of G’MIC 2.0.0 is almost there. Default downloads now link to today’s prerelease, so more people can try it !

Would it be possible to show the amount of scale under the preview?

An edge case bug: In preview mode (0) (1:1 pixel size) the preview image aspect is affected by the aspect of the interface itself. Edit: only if the initial preview window is smaller than the source image!
Example: use deinterlace2x with aspect 16:9, reduce the width of the gui and stretch the height so it’s tall & thin. The preview image gets stretched in the opposite way - it gets wider relative to height.
Sorry I couldn’t find a stdlib filter to demonstrate with, but even a dummy filter which alters aspect would do.
Feature request:
More user control of preview zoom, e.g. option to save zoom factor with favs.
@iarga I was thinking the same thing!

Hi Andy,
Could you please give us a step-by-step ‘tutorial’ to reproduce the preview bug ?
We didn’t manage to reproduce it. Maybe you have tried an older version of the plug-in ?
I must apologise, I now know the cause and there is no bug - only lost information.
What’s actually happening is due to the preview crop. The filter in the example uses the input h/w ratio to calculate the output aspect, but of course if your preview window is smaller than the full image the h/w ratio could be different.
For example you may have a 16:9 input but if your preview is square and the edges are cropped, the filter will “see” this as a 1:1 ratio. So long as there’s no way of passing full image parameters to the filter there’s no way of fixing that.
Very sorry to have wasted your time 
Not sure I’ve get all the details of your issue, but wouldn’t it be interesting for a filter to have access to the preview window size in pixels, maybe having them stored in variables such as $_preview_width and $_preview_height ?
EDIT: In fact, this is already the case, these variables are defined by the plug-in, so a filter can get the preview size very easily.

Very useful to know, I had no idea! 
I’ll be sure to make use of that, thanks.
