Why would there be a problem with portables? So long as there is a "scripts" folder in the gimp-directory it should work - even if the gimp-directory is something outlandish like "Z:\some\path\via\Timbuktoo\.gimp-oujamaflip" so long as the G'MIC environment variable "path_gimp" is set to that path (which it must be for G'MIC to work at all) and there is a "scripts" folder in that directory, then it should work.

As to the matter of script managers installing to sub-folders, I don't really see a way around that at the moment.

That would be a folder called "gmic-presets" in your main gimp-directory (ie. .gimp-2.8).
I can't see that really helps either with scripts managers installing to sub-folders or with portables.

Do I need the presets file and if so, where does the presets file go? I have Windows 7. 64 Bit.

Tested out the script presets these are the ones that didn't appear or give an error:
Hallucinogenic
In the Bushes
Flowers

Both the .scm and the .gmic file must go in your user scripts folder - NOT the system-wide scripts folder
ie.
On Windows: C:\Users\<user>\.gimp-2.8\scripts
On Linux: /home/<user>/.gimp-2.8/scripts

For me on my PC, all of the presets now work through the GMIC Logos script. Thanks Jontait2.

How so? It sounds like you're thinking of treating the .scm and .gmic as separate entities to be handled by installation managers. But if they are treated as separate entities, they can still both be installed to the normal scripts folder (surely?).


Including the presets in the script itself is a pretty horrible solution - I did have a look at that when David first suggested using a .gmic file, but there are problems:
- the entire set of presets would have to be stored in the script as one great long string (approx 60,000 characters) - which may be problematic - or broken-up into manageable units. I'm not sure whether TinyScheme does actually have a maximum string-length, but I have had problems trying to use very long strings before;

These filters are not available in Gimp-G'MIC itself - even after installing this script you still won't be able to invoke the presets actually used by the script manually from the G'MIC plugin's menu tree - the presets are only loaded temporarily when the script runs, and then immediately forgotten about. The next time you run Gimp G'MIC it will have no "memory" of the presets!

@Graechan
Unfortunately the syntax changes in G'MIC 1.6.5.0 have broken the "G'MIC Logos" script again - specifically, the 3 options which use presets in the newly-introduced Gmic-Logos-presets.gmic file (ie. "Hallucinogenic", "In the bushes" and "Flowers").

The problem is that the G'MIC command to load that file was using the @{-path_gimp} construct to find the user's .gimp-2.8 folder and that syntax has changed to ${-path_gimp}.

So I have amended the script to use the Script-Fu platform-specific literal "gimp-directory" instead - this should allow the script to work with both old and new versions of G'MIC.

Please try the above script on Windows and, if you're happy with it, rename as Gmic Logos.scm and post it on GimpScripts as Rel 2.1.
Cheers.
