Error while executing script-fu-inlay:

Error: eval: unbound variable: script-fu-chrome-logo-alpha


GIMP Warning
Plug-in 'Inlay' left image undo in inconsistent state, closing open undo groups.

---

I have many scripts now which are giving me this error of an unbound variable leaving image undo in an inconsistent state.

I tried to find the answer here in the archives but was not successful.

Is there something I can do to resolve this? Is there something in the scripts which needs to be edited? I may have had this problem for a while now, maybe with the jump to the 2.10 series, but i'm not entirely sure.

Thanks

"script-fu-chrome-logo-alpha" is probably in the alpha-to-logo collection, which has been dropped from the "factory" build in 2.10. You can find it here: https://download.gimp.org/mirror/pub/gimp/extras/ in gimp-data-extras-2.0.4.tar.bz2

I have quite a few scripts giving this error.

I have quite a few scripts giving this error.

I can't guess the content of each script Otherwise the names of many constants have been changed, and IIRC someone (Tin?) has a script to fix the old scripts.
