Quoting David Gowers <[EMAIL PROTECTED]>: > You defined zac-autocrop correctly, but you haven't registered it with GIMP. > See this link for an example. If you are calling a Script-fu defined function from the command line, it is not required that the function be registered with the PDB. The definition will be loaded when Script-fu is initialized and the function made available within Script-fu. PDB registration is only necessary if you wish the defined function to be made available to plug-ins or scripts in other languages. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Thanks guys, I've figured out what to do from your pointers! Didn't realize there's a difference between _ and -. Zac ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

You don't use _ in the names of functions in Script-Fu. 'plug_in_autocrop' should be 'plug-in-autocrop'. If you wrote zac-autocrop to load, crop, and re-save your files, why does your GIMP command line shown above call plug-in-autocrop instead of zac-autocrop? -- Cheers!

script-fu is something I do not use, so I will give my example
implementation in a form that you could call from the PyGimp console.
def autocrop_many (pattern):
import glob
filenames = glob.glob (pattern)
for filename in filenames:
#the following is a direct translation of your script-fu.
image = pdb.gimp_file_load (filename, filename)
drawable = image.active_layer
pdb.plug_in_autocrop (image, drawable)
pdb.gimp_file_save (image, drawable, filename, filename)
pdb.gimp_image_delete (image) # this line may not be needed
If you paste the above into a PyGimp console, then call it like
autocrop_many ('/path/to/files/movie*')
it should do what you want.
If you don't have python support installed, I can only help by
pointing out basic errors in your code; I know little of script-fu

* plug_in_autocrop accepts an image as it's first parameter, but you
provided a filename.
(you also are trying to call 'plug_in_autocrop', whereas the function
is named 'plug-in-autocrop'. -/_ substitution is only used if you're
coding your plugin in Python.)
I think you meant to call zac-autocrop here, anyway.

^^
the above line has the _ / - mistake I pointed out earlier in this email.

You defined zac-autocrop correctly, but you haven't registered it with GIMP.
See this link for an example.

Re: [Gimp-user] Exact crop question
Hi David, Thanks for answering my question so quickly. I realized that I should have phrased my question more carefully. What I want is to be able to autocrop all the images matching a pattern, say "movie*.jpg". How do I do that? I tried something below, but that didn't work. =( Thanks!
