Hello there,
Well, here I am again to announce another release of a new version (numbered 1.7.7) of the G'MIC image processing framework. As always, I encourage upgrading to this new version as soon as possible .
Particularly this time, as we found (and fixed) two critical bugs in colorspace conversions RGB->HSL and RGB->HSI in the previous stable version.

This version is backward-compatible with the previous one (1.7.6), meaning that all new filters added in this version have been also _backported_ for users of the previous stable version.Here is the following is the full Changelog of the version 1.7.7, as compared to the previous stable version 1.7.6.
Enjoy !

---

New features:

- [stdlib] New command -rolling_guidance implements the rolling guidance filter (ECCV'2014 paper from Qi Zhang-etal.).

- [gimp] New filter Artistic / Sharp abstract creates image abstractions using the rolling guidance filter.



- [gimp] New filter Details / Sharpen [texture] implements a new image sharpening algorithm based on the rolling guidance filter to separate and enhance texture part of an image.

---

Improvements:

- [web] Default downloads of pre-compiled binaries now links to the pre-release of the incoming version (not the case for the source `.tar.gz` package). G'MIC is considered as stable enough now to propose the cutting-edge development versions to the users by default.

---

Bug fixes:

- [core] Fixed two critical bugs in color conversion commands -rgb2hsl and -rgb2hsi. These commands were not working correctly in version 1.7.6.

- [core] Fixed small bug in commands -bilateral and -guided : wrong result was returned when std_variation_r==0 and std_variation_s!=0 (or if guide was a constant image).

I'd be really interested by what you think about this new sharpening filter in G'MIC. I find it already really cool and useful, but I'd like to know what you power users think about it !

Oh i like this Sharp Abstract filter David.

Sharpen Texture

Very good additions, David!

David, Thank you so much for your new nice additions in G'MIC. Great Job!
But I ask please check this problem I have since I installed the new release in my computer. When I try to run a filter, I get this error message (attachment). I've checked everything about installation and it seems to be right. Also, it may be that the problem occurs ONLY on the 32bits version, But it is sure that the 64bits version runs properly.
Thank you so much.

Isabella, it seems your error occurs when invoking a script from dinasset, am I right ? In this case, I'm afraid I can't do anything right now. We should wait for dinasset to investigate the issue.

all my filters, including that one, run properly in the new G'MIC version BUT I'AM USING THE 64BITS VERSION.
Issabella pointed out that this may happen only on 32bits version (something missing or incorrect in the 32bits preparation?)

AFAIK also animicule had problems with the new version, but I'm not aware of the version of his OS

edit: he uses 64bits version, so not the same

can anybody else running 32bits version double check?
(i.e. having 1.7.7 and running that filter with option "Anguish")

I ask Issabella to check all the PP options.
For Anguish it could be caused by a parameter value outside the range, not checked in the previous versions of G'MIC
(but, interactively, it works fine with those parameters, running "Custom code", so the check should not be there, at least in the 64bits version)

I get the same error.

this is the same as previous test
pls check other PP (for this specific try the version I sent via e-mail)

this is the outcome obtained interactively

using
[G'MIC] Custom code (global): -gimp_custom_code "-repeat $! -l[$>]
-samj_Angoisse_en 1,5,0,5,100,2,4,1,2508
-endl -done
",0,0,0

OK, Issabella, seen your last post: hence, that last parameter is not the cause
let see whether other G'MIC calls abend
try all the PP, Issabella

OK, Thank you so much.

David, Dinasset, please SORRY as it was my blame that I didn't refresh the filters after install the new release.

It works great now and I feel so embarrassed. Excuse me please.

'all's well that ends well'.

Ronounours,

Is there a way to refresh the filters by downloading a file or files
to a flash drive to move them to my home computer?
I do not have internet connection to refresh online.
I use the same filter that Dinasset made.

Thank you for your time!

Yes, basically you have to consider the 3 digits of your G'MIC version (let say 1.7.7 for now), and then you download the filter update file here : http://gmic.eu/update177.gmic.
After that, you have copy this file directly into your local gmic/ configuration folder.
This folder is located either in $HOME/.config/gmic (on linux) or %APPDATA/gmic/ (on windows).

Thank you!
I will do so!
