Some Samj filters have Disappeared[Solved by Jontait2]

Graechan · **Posted:** Sat May 23, 2015 9:03 pm **(#1)**

Several Gmic filters from Testing/Samj have disappeared does anyone know where they went or where they are being shifted to

This has resulted in my script 'Gmic Logos' being faulty and I'm at a loss as to how to fix,
or was it a mistake to use Gmic to create a script in the first place

Gmic Logos Rel2 will be posted soon (this will restore the missing Samj filters) thanks to Jontait2

but in a previous post you said "I believe David is doing some changes to 3rd party filters so I'll wait untill he announces these "
I imagine you still have to wait...(the Testing group is the most affected)

Yes; forgot about that dinasset. It's possible that they may be located in different subcategories now.

Graechan · **Posted:** Sun May 24, 2015 12:09 am **(#4)**

here is a list of the missing Gmic filters and the 'Gmic Logos' Options affected
Wild Cactus

which used -samj_CeKoaSa_007

Hallucinogenic

which used -samj_Formes_Couleurs_Variees_Dans_Image

Colored Wind

which used -samj_Wind_Quatre_Zones_001

In the Bushes

which used -Remplir_Fleurs_2_samj

Flowers

which used -samj_dessiner_une_fleur

I'm still waiting on David for more information

I have noticed at least one that I thought was missing is in a different place now. Not under testing anymore but has [samj] after it.

Graechan · **Posted:** Sun May 24, 2015 12:36 am **(#6)**

Sallyanne if it's one of the ones I'm missing which one and where did it go :tyspin

sallyanne · **Posted:** Sun May 24, 2015 1:21 am **(#7)**

I cant find the ones you mentioned Graechan but there are about 31 in amongst the different categories.

3 in Arrays and Tiles
6 in Artistic
1 in Black and White
1 in colours
1 in Degradation
2 in patterns
and 18 in Rendering

I addressed this in another thread: viewtopic.php?f=8&t=12520#p169900

David is currently making changes to how third party scripts and filters will appear in G'MIC. Please stand by for further information from him (or just like me if nobody has said anything in a while).

It's been a long standby for any information about the filters :hoh

Will the filters return and if so will they be renamed or just reassigned :hoh

You might have to do some hunting Graechan; 1.6.3.1 has now been released so they should be there somewhere. I did PM David (via Flickr) but didn't get a response yet. He's busy; G'MIC is just one of many projects that I'm sure David's working but I'm sure he will address the issue shortly now that 1.6.3.1 has been released.

Just noticed a few of samj's presets are located in a few different categories depending on what they do. Some are actually located under render by the way. Bet you all of her presets are there; they've apparently been canonized (and being fantastic as they are, they deserved to be). Testing is just that; testing. Some of these presets are over a year old (and some may even be older). Long enough to get from testing phase to finalizing.

I wouldn't personally have considered one day to be a long standby time...

Yes, the filters will return, and they may live in a different location.
In fact, they may still be somewhere in the filter tree (they were just moved to a different location).

Let me explain what's happening...

G'MIC is a powerful program that uses a scripting language to allow some low-level access to things. This means that it has the potential to do Very Bad Things™.

David is (rightfully) concerned that any malicious scripts from third party users could potentially open him up to liability. So by default third party scripts that he himself did not write or approve will need to be manually enabled by end-users, who can do it knowing the risks (same as any person installing software from someone they don't know on the internet).

This is actually a smart move on his part, and is being done in consideration of users safety.

Hello there,

I confirm that there may be some changes for some filters location, but actually no removal.
Most of the changes concern filters from samj, and some of them have been moved to Testing/Samj/.
What I did should not break existing scripts using samj's filters, so maybe samj has also do some changes in the filter names, which would explain the issues you have. I cannot say much about these changes by the way.

Graechan · **Posted:** Tue May 26, 2015 7:54 pm **(#14)**

Due to the fact that Samj has cut us of completely there is little I can say or do as well except consider it a lesson and delete the affected options, I assume by your comment that you also no longer have contact with her (this saddens me).

Ronounours · **Joined:** Jan 03, 2011 **Posts:** 1656

I still have contact with her sometimes (and you can do as well, just by writting her an e-mail

) ).
I'm not really familiar with writing .scm scripts, so I'm not sure I can solve your problem easily. What I can say anyway is that the G'MIC commands whose name start by gimp_ are quite volatile by nature : with the plug-in update mechanism, the chance they are modified (renamed or with new parameters) even between two new versions of the plug-in is high, so this is somehow quite adventurous to use them in .scm scripts

What you can do is defining your own G'MIC commands in your .scm script, and call them instead, so you are sure they won't move.
You can even do a copy/paste of the samj's commands if necessary. To define a new G'MIC command in a G'MIC pipeline, use the -command command, like in this G'MIC pipeline :

Code: Select all

-command "foo : -blur 10 -mirror c" -foo

I'm a little unsure of how to do this but I can try

I found this code for CeKoaSa_007 in a Gmic 1590 update but I'm not sure how to apply it

Code: Select all

#@gimp Cekoasa 007 : samj_CeKoaSa_007, samj_CeKoaSa_007_preview(1)
#@gimp : Sep = separator(), note = note("<span foreground="orangered"><small>Colors / Couleurs</small></span>")

#@gimp : Sep = separator(), note = note("<span foreground="orangered"><small>Gradient Norm</small></span>")
#@gimp : Douceur / smoothness = float(0,0,10)
#@gimp : Sep = separator(), note = note("<span foreground="orangered"><small>Rodilius</small></span>")
#@gimp : Amplitude = float(10,0,30)
#@gimp : \303\211paisseur / thickness = float(10,0,100)
#@gimp : Nettet\303\251 / sharpness = float(300,0,1000)
#@gimp : Orientations = int(5,2,36)
#@gimp : D\303\251calage / offset = float(30,0,180)
#@gimp : Douceur / smoothness = int(0,0,5)
#@gimp : Sep = separator(), Type Aper\303\247u = choice("Tout","Rendu en bas","Rendu a droite","Rendu en haut","Rendu a gauche")
#@gimp : Sep = separator(), note = note("<small>samj - Derni\303\250re mise \303\240 jour : <i>2014/04/24</i>.</small>")

@Graechan

I've got the Wild Cactus to work by replacing the existing call:

Code: Select all

            (plug-in-gmic 1 image gmic-layer 1
               (string-append
                  "-v - " ; To have a silent output. Remove it to display errors from the G'MIC interpreter on stderr.
                  "-samj_CeKoaSa_007 1.20,0,10,10,300,10,30,0,0")
            )

with this command definition and invocation:

Code: Select all

            (plug-in-gmic 1 image gmic-layer 1 
               (string-append
                  "-command \"graechan_wildcactus : "
                  "-pow[-1] 1.20 "
                  "-c[-1] 0,255 "
                  "[-1] "                  ; was "--gimp_do_nothing[-1] "
                  "-gimp_gradient_norm[-1] 0,0.5,0,100,0 "
                  "-gimp_rodilius[-1] 10,10,300,10,30,0,1,0,0 "
                  "-blend[-1,-2] grainextract,1,0 "
                  "\" -graechan_wildcactus")            
            )
   )   

The above command is the core sequence from samj's CeKoaSa_007 preset:

Code: Select all

 -pow[-1] $Colors_Couleurs
 -c[-1] 0,255
 --gimp_do_nothing[-1]
 -gimp_gradient_norm[-1] $Smoothness_GN,0.5,0,100,0
 -gimp_rodilius[-1] $Amplitude_R,$Thickness_R,$Sharpness_R,$Orientations_R,$Offset_R,$Smoothness_R,1,0
 -blend[-1,-2] grainextract,1,0

but with your parameters substituted in place of the $xxx parameters.

Alternatively, you can do it all in one line like this:

Code: Select all

(plug-in-gmic 1 image 0 1 "-command \"graechan_wildcactus : -pow[-1] 1.20 -c[-1] 0,255 [-1] -gimp_gradient_norm[-1] 0,0.5,0,100,0 -gimp_rodilius[-1] 10,10,300,10,30,0,1,0,0 -blend[-1,-2] grainextract,1,0 \" -graechan_wildcactus")

Notes:
- when defining a command, GMIC expects the command to be contained between double quotes, which conflicts with Scheme also using double quotes to delimit string definitions, so you have to "escape" the GMIC command's quotes using backslash like this: \"
- the GMIC dummy procedure gimp_do_nothing no longer exists; it was only being used in this preset to create a new layer copy of the input (active) layer; nowadays, just [-1] will achieve the same result.

The other missing presets are going to be a bit more difficult - they're all rather long with lots of options and you/we need to sort out which bits you do need and then discard the rest.

Very cool answer jontait2, I was not sure how to do this in Scheme.
Thanks a lot !
