[Gimp-user] GAP scripting?
I need to do a complicated GAP animation. It involves many steps that I will probably need to redo several times. A script that I could edit and re-run multiple times so that I can get it right.

In GIMP 2.2 functions in one file were defined in a way that made them available to be called by scripts in other files. While this can be a useful feature at times it can also cause problems. There were two scripts that defined point-list->double-array which took one argument. The routines were different and as a result, one of the two scripts appeared to be broken as it wound up calling the wrong version of the function. As of GIMP 2.4, the scripts which ship as part of the Script-Fu plug-in define the functions they need locally (ie. other scripts can't access them). This avoids the problems of adding a new script and finding out that some other previously working script no longer works. -- Cheers!

Re: [Gimp-user] Urban Acid script (buggy)
Owen,
Thanks for confirming that it works in 2.2 under Ubuntu and crashes on 2.4.
I too got that unbound error on 2.4 . I declared all the variables, which
cleared that up under Windows. I still got the unbound error in Ubuntu,
which is odd since set-pt is a function, not a variable??
So I added this in the hopes it would clear up:
; define the set-pt procedure (used to be embedded??)
; from http://adrian.gimp.org/scripts/shagadelic.scm
(define (set-pt a index x y)
(prog1
(aset a (* index 2) x)
(aset a (+ (* index 2) 1) y)
)
)
This is added before the "(define (splineValue)"
It appears that set-pt is defined ("built-in?") in the Windows 2.4.1 build
but not Ubuntu 2.4?
However, with that function thus defined, the Ubuntu version behaves as
quirkily as the Windows version. Doesn't appear to do anything, but
proceeds to make GIMP act weirdly.
This odd behavior is why I am appealing for help. I appreciate your
sleuthing.

It looks like this is only happening when I'm working on files that are being served over NFS. I've got a central fileserver at home where I mount /home from, which is where most of my Gimp files are contained. The couple that I had tried that had worked were outside /home but I didn't think to see if that was the causative case or not. I'll be digging around more to see if I can figure out what's going on more specifically, but it'd be nice to see if anyone else can reproduce it by saving to an NFS share. -CJ -- WOW: Flemmy| "The ships hung in the sky in much the same [EMAIL PROTECTED] |way that bricks don't." - Douglas Adams, 24.24.2.3171 | _The Hitchhiker's Guide To The Galaxy_ ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] Urban Acid script (buggy)
Following is my "Urban Acid" Script-Fu program. It attempts to simulate the famous Photoshop Urban Acid action, which dramatically alters the color curves. The program worked well in GIMP 2.2, but is buggy in v2.4. I am having the following problems: * The first time, it runs but the working layer shows no difference. Indeed, even the mode is not set to overlay. * The second time executed, not seems to happen. Not even a copy layer is created. * GIMP seems to increasingly act weird after that. Scripts may or may not run. The entire experience looks like a memory over run. I am now running GIMP 2.4.1 under Windows, but I saw the same thing in 2.4under Windows and also Ubuntu (Gutsy Gibbon).
