Hi I want to export all the images from a folder in one go on a windows machine.

I am trying to use the "file-jpeg-save" from command line but getting error stating batch command experienced an execution error.

The command I am executing on windows command line is

set gimp="c:\Program Files\GIMP 2\bin\gimp-console-2.8.exe"

for %i in (*.jpg) do %gimp% -b "(file-jpeg-save 0 %i drawable %i %i 90 0 1 1 comment 4:4:4 1 0)"

Can anybody help me to undestand the issue.

Thanks in advance

You can only export something you have loaded first.

But if what you want to do is change some characteristics of a JPEG file, you should look into the "convert" command from the ImageMagick toolbox.

The code passed on the command line -- in your case, file-jpeg-save -- needs to be valid Script-fu, just as used within scripts. This means that second argument needs to be the image ID of an opened image, not the name of the file on disk. Your code needs to load the file as an image and then determine the layer ID of the image's layer before you can save the file as a JPEG.

Also, your command is looping through, opening GIMP for a file and then closing GIMP only to have to re-open GIMP for the next file. It is far better to just open GIMP once and then perform the looping within you script code.

I have written a macro that simplifies this process somewhat, and can be downloaded from HERE. Save it to a file in your GIMP scripts folder and then code such as the following should work. (Warning: this command will overwrite the original JPEG files.)

Not quite sure what that is intended to do, but for a GUI you could try the BIMP plugin http://www.alessandrofrancesconi.it/projects/bimp/

Thanks for your reply. I have copied the macro to script folder. But, the command is still throwing error for me. I am just a toddler with the tool, can you please give me a command that I can copy/paste & it works for me.

The current command(s) I tried are

1.
set gimp="c:\Program Files\GIMP 2\bin\gimp-console-2.8.exe"

%gimp% -i -f -b "(with-files \"*.jpg\" (file-jpeg-save 0 \"C:\\temp\\1.jpg\" drawable \"C:\\temp\\1.jpg\" 90 0 1 1 \"\" 0 1 0 0 ))"

2.
set gimp="c:\Program Files\GIMP 2\bin\gimp-console-2.8.exe"

%gimp% -i -f -b "(with-files \"*.jpg\" (file-jpeg-save 0 -i drawable -i 90 0 1 1 \"\" 0 1 0 0 ))"


Thanks a lot, plz help

I do not use Windows or have it available for testing, but I believe that the command I previously posted should work.



If you leave out the -i switch then you will be able to see whether GIMP actually opens and the status bar shows the processing of each of the files. The -f switch can also be left out but then GIMP will take some extra time to load your fonts (which aren't ever used).

Note that image, layer, and filename are the literal words -- you should not substitute anything else in their place (the macro takes care of this).

EDIT: Changed run-mode to NONINTERACTIVE per correction suggested by paynekj.

It's working for me on a Windows 7 machine, although I am puzzled why you set the run-mode of flie-jpeg-save to RUN_INTERACTIVE as, despite the -i flag, I get the save-options dialog appearing for each file!

Things to be careful of.
The path to the gimp executable must be correct.
Don't put any spaces round the equals in the set command:WILL NOT WORK

Wearing Why complicate life.
Rich2005 gave a simple and effective solution
Why are you ignored?

Because it is like doing a crossword, it is a challenge with great satisfaction when you get it to work.

plus to be honest, command line was in the subject

Copy and paste error on my part. I almost never use numeric values in place of enumerated constants -- it is much easier to read the code and spot errors when things are spelled out.

@paynekj

I have removed the intractive tag the cmmand is getting executed but I am still getting a error msg, screen-shot attached

Please advice.

Solutions are many - for you should be using the simplest solution BIMP (rich2005) - why the command line is to be a better solution?

Why are you interested in only the command line - why that is?

Oops. The jpeg compression level needs to be normalized. Change it from 90 to 0.9 .

@saulgoode

Changed the argument to .9 as suggested, still getting error
Anyone please help me to pull this one off, I am really sorry I am posting every day with a new issue, but can't help it I have just started using the tool & you guys are the best help for me, appreciate your quick replies.

Please suggest





Thanks

Well, the error now appears to be caused by some file called "bimp-locale". To my knowledge, this has nothing to do with my macro and is not part of bog standard GIMP.

I think you will find that the errors have nothing to do with the batch process.

If you check your files, you should see that they have changed.

Kevin

The error message about "bimp-locale" is just a red-herring - that file is actually a folder containing locale-specific settings for the BIMP plugin, but GIMP is too stupid to realize that it's not an executable file and so tries to actually load and execute the folder, and inevitably fails. So you can safely ignore that error message - that will probably always happen but you don't normally notice it. [The same thing happens with any other folders or non-executable files included in the plug-ins folder, but you only see the error message if you start GIMP from a console!]

As Kevin said, the batch process probably is actually running, so check to see if your .jpg files have actually been processed.
But you should terminate the batch run properly with:

Ref: http://www.gimp.org/tutorials/Basic_Batch

So try:

Actually, the gimp-quit is already included at the end of the with-files macro:

Ah!

@Saul
A minor point: using the usual command-line batch syntax -b '(...)' -b '(gimp-quit 0)'
produces the message: "batch command executed successfully" on completion of the first -b '(...)'
[There is no message from the second -b because that batch run never actually finishes - the GIMP core terminates itself when it gets the quit command, and the host OS then kills the child processes, including the script-fu plugin. So the Script-Fu engine never actually completes execution of the script and never outputs the second completion message.]

Ergo, including the (gimp-quit ) in your (with-files ) macro means that there is no completion message output at all.
Perhaps you could output a bespoke completion message eg. of the form "macro with-files completed, N files processed, quitting GIMP..."
