GIMP Version: 2.6.12
Operating System: Windows
OS Version: XP - SP3
GIMP Experience: Beginner Level

Does anyone know how I can use the wavelet sharpen plugin on a directory of images (batch)?

I tried in the command line:

gimp.exe -i -b '(batch-wavelet-sharpen "*.jpg" 0.3 1.0)' -b(gimp-quit 0)'

and

C:\Program Files\GIMP-2.0\bin\gimp.exe -i -b '(batch-wavelet-sharpen "*.jpg" 0.3 1.0)' -b(gimp-quit 0)'

and

C:\Program Files\GIMP-2.0\bin\gimp-2.6.exe -i -b '(batch-wavelet-sharpen "*.jpg" 0.3 1.0)' -b(gimp-quit 0)'

which gets me not a recognized command

You would need to write a script incorporating the call to plug-in-wavelet-sharpen

the script would need to get a list of the files to process - all files ending *.jpg ?
open each file in turn
call plug-in-wavelet-sharpen passing in the image numeric id and drawable numeric id
save the file - overwrite the original?

And here's a script to do it:

Attachment:

File comment: As usual a zip file because I can't attach plain script files.

batch_capnhud_wave_sharp.zip [1.13 KiB]
Downloaded 186 times

I've put the plug-inwavelet-sharpen parameters inside the script, but it would be relatively simple to make them command line values if you want.

Code: Select all

      ; Adjust these values to suit 
      (amount 0.3)
      (radius 1.0)
      (luminance TRUE)

From the Windows command line:

Code: Select all

"C:\Program Files\GIMP-2.0\bin\gimp-2.6.exe" -i -f -d --verbose -b "(batch_capnhud_wave_sharp \".jpg\" \"sharpened\")" -b "(gimp-quit 0)"

You may need to edit the path to the GIMP executable to match your system.

In the example above I've made the command line save the sharpened images into a folder called sharpened. If you want to overwrite your existing images change \"sharpened\" to \".\"

Well that explains why running the commmand was not working.

Thank you for taking the time to do this.

Just one question what if the directory contained .png and .jpg would the part in the script change to \".jpg, .png\"

No. The way the script is written it can only do one file type at a time, so run it on .jpg then change to .png and run it again.

Correction: if you make it \".*g\" then that matches .jpg and .png, but be warned this will match other things as well: .gig .pig .zog .anything_at_all_ending_in_a_g ..... you get the idea

I feel I must confess that I didn't take all that much time as I've now made a template for this kind of request, mostly thanks to doing something very similar yesterday: http://gimpforums.com/thread-batch-despeckle

maybe I am doing something wrong with the script, but each time that I run the .bat file I get a command window that ends up indicating the following when attempting to process an image.

The .bat file is in the directory that the images are in so all I am trying to do is just process and overwrite but error prevents any processing from happening.

when I run the following from the command line or .bat file

Code: Select all

"C:\Program Files\GIMP-2.0\bin\gimp-2.6.exe" -i -f -d --verbose -b "(batch_capnhud_wave_sharp \".jpg\" \".\")" -b "(gimp-quit 0)"

i experience

Code: Select all

No batch interpreter specified, using the default 'plug-in-script-fu-eval'.
script-fu.exe-Warning: processing-th_alps_60266_6743902.jpg

batch command experienced an execution error

EXIT: gimp_real_exit

EXIT: batch_exit_after_callback

(Type any character to close this window)

and script

You have commented out the definition of the amount variable:

Code: Select all

      ;(amount 0.3)

So when the script gets to the place where it is used:

Code: Select all

              (plug-in-wavelet-sharpen RUN-NONINTERACTIVE image drawable amount radius luminance)

It will be throwing up an unbound variable: amount error.

I tabbed the wrong word when using autocomplete to help keep the original, but make changes as I needed. It never occurred to me that something was wrong with the script, since I have used it with no problems before. thank you for pointing out my mistake.

batch command executed successfully
