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

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.

Hi David, Thanks for answering my question so quickly. I realized that I should have phrased my question more carefully.

[Gimp-user] Exact crop question
Hi everyone, I'm wondering if there's an automated way to crop my images of all the white areas on the outside. Basically I've produced quite a few MATLAB plots exported as JPEGs. There's a lot of white around the sides, and the figure is in the center. Is there an automated way to crop exactly the white parts around the figure away? That would save me time from having to zoom in to each picture and do the cropping manually. Thanks!
