Introduction¶
GIMP comes with a so-called batch mode that allows you to do image processing from the command line. It also makes it easy to apply the same set of operations to a number of images. We have got a lot of questions on the mailing-lists on how to use the batch mode and this small page tries to explain the basics to you.
Gimp Photo Processing Tools
GIMP can be started with a number of command-line options. Let’s have a closer look at the output of
gimp --help
:In order to do image processing from the command-line, you usually use the Script-Fu batch interpreter. This is the default, which makes things simple. To give you an impression of what can be done, try the interactive console mode:
This will tell GIMP Hp easy scan app for windows. to start in batch mode and accept commands on the command-line. This is essentially the same as using the Script-Fu console. It would however be tedious to enter the commands here, so instead we will create a simple script and show you how to run that:
A simple example¶
This simple script takes a filename and some numeric parameters. It opens the respective file, applies the Unsharp Mask filter and saves the image again (be careful, for the sake of simplicity this script overwrites the original image). It does all this w/o any user interaction, so we can run it without any user interface. In order to do that, save the script with the .scm extension in the ~/.gimp-2.4/scripts directory. Then run it like this:
There is a catch here: Some plugins or Script-Fu scripts create new layers and then flatten the image again. This changes the drawable ID. If this is the case insert the following line to get the current drawable ID just before saving the image:
Processing several files¶
You might want to apply an effect to a number of files, typically to a set of files in the same directory. GIMP 2.2 added a very useful function for this purpose, the file-glob plug-in. This turns GIMP into a versatile batch processor. In order to use it, we will need to do some modifications to our script:
This version of the script takes a glob pattern instead of a filename and will apply the Unsharp Mask filter to all files matching this pattern. In order to sharpen all PNG images in the current directory, you would run the following command:
Further information¶
If you want to write your own scripts for batch processing, we suggest you use the Procedure Browser as found in the Help menu. It gives you a detailed list of all commands.
