Hi,

When I install new scripts in GIMP 2.7.2 i can't see them even after re-opening the program.

I am interested in layerfx.scm

Any help, please?

I suspect the problem is down to how you have "installed" the script.

What exactly did you do to install it, specifically where did you put the .scm file?

Kevin

Hi,

I put them into the following directory:

C:\Program Files\gimp-2.7.2\share\gimp\2.0\scripts

OK, that's not the best place, but it should work.

Can you confirm that you put individual .scm files into that folder and NOT a zip file.
Also in Gimp select Edit->Preferences and have a look at the folders section - specifically for the scripts.
Does the folder you detailed appear in the list?

Oh and where did you get the scripts from? I ask because layerfx.scm isn't one I have so I can't tell you where it will appear in Gimp's menus.

Hi,

I downloaded the scripts from Gimp scripts from www.registry.gimp.org
Some are downloaded as .scm but some have to be unziped, which i did

I can see the folder through the preferences

What would be the best place to install the scripts?

Just confused i guess.

Just a reminder that there are pinned threads at the top of the Gimp Help forum with some basic script/plug-in install instructions, as well as the recommended folder locations for installed scripts.

viewforum.php?f=8

LayerFX should appear in a new separate menu item "Script-Fu" in the image window menu bar.




Are you sure you are saving them with a SCM extension and not a TXT extension?

IIRC, when you save in windows you have to be careful or microsoft will add the txt extension on to the .scm ie, script.scm.txt. I think you have to make sure you have "all files" selected when you save or that will happen. And on my old pc, which was XP SP3, I put my scripts exactly where you have put yours and they worked perfect...after I learned how NOT to have the .txt extension.

All my scripts have the extension .scm. I made sure if they were provided in text format I had to replace the .txt with .scm and save as type "All"

Maybe my GIMP is corrupt, but seem to me working well. I might have to download a fresh copy.

Thanx to all.

I dont think its Gimp try this -
Right click the script
Select properties
At the bottom of the window check to see if you need to un-block it.
That is sort of a way Windows CHMODS it's files.
I do have to do this quite a lot with SCM and Python files.

Maybe with gimp 2.7.2 the python version of that script could be better because offer also a sort of preview

Anyway it is possible that you didn't found the script only because you didn't know where to look ?

because there is no way to predict where a script will be installed , except if looking to the script
BUT that is easy and don't require know any coding, because is all in a line always written in plane english and always very close to the end of the script

let see where i chose a script i open with the notepad ( In Win better Notepad++ then the basic notepad )

Don't get scared you only need to look at what close to the end, here in big bold and red

"Roy Johnson"
"2009, Roy Johnson"
"June 2009"
"RGB* GREY"

Now look what big and in bold, that is clear as english may be, again this block on line is always close to the end of the script

(script-fu-register "script-fu-max-loc-contrast"
_"<Image>/Colors/Contrast/Maximize Local Contrast..."
"Stretch contrast based on local pixel maximum and minimum values"
"Roy Johnson"
"2009, Roy Johnson"
"June 2009"

What highlighted _"<Image>/Colors/Contrast/Maximize Local Contrast..." is where the plugin in the menu, here is image windows, COLORS menu, Contrast submenu

Note that now you may also change , as exmple if you prefer have it in the Filters menu
_"<Image>/Filters/Contrast/Maximize Local Contrast..."

or even create a new menu "MyScriptCollection"
_"<Image>/MyScriptCollection/Contrast/Maximize Local Contrast..."

anyway to know where to search the script in menu just look for that line,

Thank you Rod,

That worked for me, too.

Stay well.

You bet, glad to be able to help.

Stay well yourself.

as for the "layer effect" script nobody may predict where will be installed because there are several variants of same script each use a different place (from new "Fx foundry " or "Script fu" menu, to the more probable Layer menu,or even in the Filters menu )

I downloaded the new released GIMP 2.7.3 by Partha, and everything worked fine with all scripts spearing like in Rod's screenshort.

Thanks to all.

If you are interested in having the script show in Layers here is the code.
Attached as a zip file.Just delete the original, and unzip to your script directory.

With this code all the scripts will be located in the Layer/Layer Effects sub menu.
Like this:


You will also see the name of the layer script as installed (layerfx.scm), at the end of each description pop-up.
Very useful if you ever want to find the installed script.
Example:

By the way make sure to add a alpha channel to the layer so the script will work.
LayerFX.scm doesn't work without an alpha channel.
