Suppressing the "press any character to close this window" message in Script-Fu

Hi all,

I've written a series of scripts to automate GIMP's script-fu batch
processor. Right now I'm working on starting up multiple asynchronous GIMP
processes.

The problem I'm having right now is with the interactive "press any
character to close this window" message that appears when GIMP finishes
processing a piece of Script-Fu.

I want to suppress that message so that there is no user interaction
required.

Is this possible in Script-Fu?

I'm not familiar with that message. Could you provide a little more
detail about your process?

Unless the image processing you are doing is quite involved, you might
find that running a single GIMP instance to be faster if you pass all
of the filenames to it at once. This way you avoid the somewhat
lengthy startup times that GIMP usually experiences.

I don't believe the message has anything to do with Script-Fu. The message
about "press any character..." sounds like a message from a machine running
the Windows operating system and it wants to close a window that was opened
to run a program and that program has now terminated.

You can get more help if you would provide more information about your
batch processing method and how you are invoking GIMP to run Script-Fu scripts.

You get this message because you are running the copy of GIMP that was
compiled as an interactive application with UI. If you don't want any
UI, then don't start the gimp binary, but use the gimp-console binary
instead.

Sorry guys. I should realize that not everyone is following my plot :)

This is the same script / process you guys helped me with a week or two ago.
I am running GIMP on a Windows machine. I have a directory of XCF files
that I want to export to JPG. I have a batch-save-as-jpg script-fu to do
this. The script-fu is invoked from a PowerShell script. That PowerShell
launches the GIMP batch processor and passes in the script-fu function,
scaling percentage, and a file glob.

The Powershell is waiting for the GIMP process to complete before it
continues the script. This is a problem becomes whenever that GIMP command
finishes, it leaves a hanging command-prompt window open that is waiting for
a key press before it will close. This causes the PowerShell to stop
executing.

This is not standard behavior on Windows. Other commands run this way would
briefly launch a command-prompt, execute, complete, and that command prompt
closes on its own. If it's not part of Script-Fu, perhaps it's part of GIMP
batch mode? If it's not GIMP that's waiting for input, perhaps it's a flag
set when launching the executable that tells Windows if it could close the
command prompt. I don't really know where to look for this.

Thank you Sven - that fixed it!
