Both functions take an image object as the first parameter and not a
filename.

Shouldn't you ask these kind of questions on the gimp-user mailing-list?
This doesn't seem to be related to the development of GIMP.

Re: [Gimp-developer] thumbnail generation for nautilus via gimp

2007-12-07 Thread Eckhard M.

Hello,

i have written my Gimp python plugin so far:

#!/usr/bin/python

from gimpfu import *
import os
import os.path

def python_thumbnailer(this_path):
  image_formats = [ 
".psd",
".xcf",
".rgb" 
  ]
  num_files = len (os.listdir(this_path))
  all_files = os.listdir(this_path)
  
  for this_file in range(num_files):
this_ext = ''
this_filepath = this_path+"/"+all_files[this_file]
if os.path.isfile(this_filepath):
  this_ext = splitext(this_filepath)[1]

  if this_ext in image_formats:
pdb.gimp_file_load(this_filepath,this_filepath) 
pdb.gimp_file_save_thumbnail(this_filepath,this_filepath)
pdb.gimp_image_delete(this_filepath)
  pdb.gimp_quit(0)
register(
  "python-fu-thumbnailer",
  "Generating thumbnails",
  "Generating thumbnails for Nautilus via Gimp",
  "Eckhard M. Jaeger",
  "Eckhard M. Jaeger",
  "2007",
  "/Xtns/Nautilus Thumbnailer...",
  "",
  [
(PF_STRING, "this_path", "Directory Path", ""),
  ],
  [],
  python_thumbnailer)

main()


But when i try to execute it with 
gimp-console  -i -n -f -d -s -b '(python_thumbnailer RUN-NONINTERACTIVE
"/home/agy/psd_samples")'

i get always 
batch command: experienced an execution error.

Did somebody know what is wrong?
Thanx.

In fact GIMP does implement special behavior for .py files. Or rather,
pygimp tells GIMP that files ending in .py should be executed by the
Python interpreter. This is what the third line in
$(prefix)/lib/gimp/2.0/interpreters/pygimp.interp does. The effect is
that you can omit the shebang (#!/usr/bin/python) if your plug-in's
filename has the .py suffix.

But you are right that all plug-ins must be executable. Files that don't
have the exectuable bit set are skipped when plug-ins are initialized.

In fact, all Gimp plugins are executables; when you call a plugin,
GIMP runs it and communicates with it through a pipe. GIMP does not
implement any special behaviour for .py files. That is why Python
plugins must be executable.

Hello,

i found the problem why the script doesn't showed up, it needs the file
permission "Exexcute".
Do not know why, i have written exporters for Blender and plugins for
gEdit both in Python but
they didn't need the permission "Exexcute".

Ok, i'm new to Python Gimp plugins.

Hello,

thanks for the feedback but other python plugins did work like Pylomo
http://registry.gimp.org/plugin?id=10976
which didn't has a header starting with #!/usr/bin/python .

I'm using Ubuntu 7.10 and Gimpo 2.42
( http://www.getdeb.net/app.php?name=Gimp ).

I don't know, but did you get any error messages when you started the Gimp from 
the command line?

If it uses python, do you need to call python #!/usr/bin/python?

Does it have the right permissions?

When I add those corrections, I get the menu item

main()

this script is copied into ~/.gimp-2.4/plug-ins but didn't appear
anywhere :(
I can't find the bug, please can somebody help me. Thanx.

In fact it turns out that ImageMagick is very often slower and needs
more memory than GIMP. If you use 'gimp -i' then the UI is not loaded
and the gimp-console binary doesn't even have the UI linked in.

2007-12-03 Thread Eckhard M.
Hello,
thanx to all for the feedback and help.

@David

This sounds nice, i will check it out. I'm trying now to create a
automatic thumbnailer 
( like http://wiki.ubuntuusers.de/OpenDocument_Thumbnails
http://wiki.ubuntuusers.de/_attachments/OpenDocument_Thumbnails/opendocument-thumbnailer
http://wiki.ubuntuusers.de/_attachments/OpenDocument_Thumbnails/opendocument.schemas
 )
and if it done i will write a small plugin called "Browse Images" that
will open Nautilus with the
directory of the opened image. If none image is loaded it will open the
home directory. 
 
My Script generates at the moment only for PSD, RGB and XCF files
thumbnails, that i have
toch change too.

I recommend you to use gimp-console instead of gimp; The GUI is
irrelevant to what you're doing.

Briefly, you need to:
1. Load the image
2. Generate the thumbnail
3. Delete the image from memory (using gimp-image-delete)

for each image in the list of images.

For a start, invoking gimp-console once for each image is fine.
Later I suggest you run gimp-console only once, for greatly increased
speed (make gimp's scripting loop over the files, rather than your
scripting.). You could do this very easily if you can rely on
gimp-python being installed on the users' machines, and use that
instead of Script-Fu. (you can also write a loop in Script-fu, but I

Hi,

As Liam suggested ImageMagick is a command line tool intended for  
precisely the sort of processing you are trying to do and will certainly  
be much lighter and faster than a full GUI image processing program like  
gimp. You could get your script to use gimp for (rare) cases like xcf  
format where you dont have an option.

The thumbnails can in general only be generated by opening a file
and processing it, to get the image data and scale it down.

An exception is that some file formats can include a thumbnail that's
pregenerated, which might or might not be a useful size.

For most image formats you will probably find ImageMagick's mogrify
or convert to be faster, or perhaps netpbm.  But neither of those can
read GIMP .xcf save files as far as I know.

Unless a file contains an internal thumbnail (as jpeg files sometimes
do), there is no way to generate a thumbnail for a file without
loading it.  So probably you're hoping for something that is
impossible.

Re: [Gimp-developer] thumbnail generation for nautilus via gimp

2007-12-02 Thread Eckhard M.

Hello Sven,

thanks for the link and the help.

there is a thing that i don't understand, my script is opening the file
and so the thumbnail 
is generated by Gimp automaticly when closing gimp.

I thought using gimp-file-save-thumbnail would be faster and uses less
memory then opening 
the files like i did. But now i read the documentation and see to use
gimp-file-save-thumbnail
i have to open the file first to get the image ID. 

So my question is: Is there an advantage using gimp-file-save-thumbnail?

Have a look at the documentation again (hint: I gave you a link). Your
call misses the ID of the image (that you need to obtain by opening it
in GIMP beforehand). And your filename needs to be in parenthesis.

Hello Sven,

thanx for that. I tried something like 

gimp -i -n -f -d -s -b '(gimp-file-save-thumbnail /path/to/image.psd)'
-b '(gimp-quit 0)'

but i didn't get it work :(

This is what have done so far:

You can use the PDB function gimp-file-save-thumbnail(). See

[Gimp-developer] thumbnail generation for nautilus via gimp

2007-12-01 Thread Eckhard M.

Hello,

i got the idea to create a python script thats generate the thumbnails
of unsupported images in nautilus using gimp.
Implementing this in Gimp and in Nautilus.

I studied the commandline options ( -n, -a, -i, -d, -f, -s )of gimp and
do not know if it is possible. Am i right i have to load and unload 
all the images of a directory to get gimp generating an thumbnail or is
there a better way?

Thanx.
