![]() ![]() Uninstall is simply delete the gmic_gimp_qt file. Unziped a gmic_gimp_qt which goes in ~/.config/GIMP/2.10/plug-ins/. If you are using a debian type ubuntu / mint… and using a zip from then this is a single (static) file. Why are these details useful ? The linux version will determine what is installed, The Gimp version to certain extent depends on the Linux version and what works. Where did you get gmic_gimp_qt ? Was a one of the zip packages from or did you install via a package manager / “software center” Which version of Gimp ? From the video it looks like it might be an older Gimp 2.10 version. Which version of linux ? Is it debian based ? Anything that uses. It appears that nothing has happened in the GUI, but the image is loaded.Uninstalling still requires the details that were requested. Define the image variable using the define function, and give it the proper path to find the image: (define image (car (gimp-file-load RUN-NONINTERACTIVE "Fourier.png" "Fourier.png"))) In this case, you cannot use let* because the variables must be persistent. First, start GIMP with the GUI enabled and the Script-Fu console, which is found in Filters → Script-Fu → Console. To help you better understand the procedure, I'll break it down. Finally, it defines the string containing the new filename of the resulting image. Then, it selects the first active layer and stores its reference in the drawable variable. It loads the image with gimp-file-load, which returns a list that includes the image, then it selects the first entry with the car function. In this case, the variables are image, drawable, and new-filename. ) function is a special procedure that allows you to define some temporary variables that are valid only inside the body. You might have noticed that variables with long names are spelled with dashes between the words this is the idiomatic style of Lisp-like languages. Everything else inside the define function is the body of the chalk function. ) function defines a new function called chalk that accepts the parameters: filename, grow-pixels, spread-amound, and percentage. In the script, the (define (chalk filename grow-pixels spread-amound percentage). (gimp-image-delete image))) Defining the script variables (gimp-file-save RUN-NONINTERACTIVE image drawable new-filename new-filename) (plug-in-randomize-hurl RUN-NONINTERACTIVE image drawable percentage 1 TRUE 0) (plug-in-spread RUN-NONINTERACTIVE image drawable spread-amount spread-amount) (gimp-edit-bucket-fill drawable BUCKET-FILL-FG LAYER-MODE-NORMAL 100 255 TRUE 0 0) ![]() (gimp-image-select-color image CHANNEL-OP-REPLACE drawable '(0 0 0)) (new-filename (string-append "modified_" filename))) (drawable (car (gimp-image-get-active-layer image))) (let* ((image (car (gimp-file-load RUN-NONINTERACTIVE filename filename))) Inside the chalk.scm file, write your first script with: (define (chalk filename grow-pixels spread-amount percentage) In my case, it is at $HOME/.config/GIMP/2.10/scripts. Writing your first scriptĬreate a file called chalk.scm and save it to the scripts folder found in the Preferences window under Folders → Scripts. Normally when you start GIMP, it loads its graphical user interface (GUI), but you can disable that with the -i option. ![]() The -b option's argument can be the script you want to run or a dash ( -) that makes GIMP launch in an interactive mode instead of the command line. You can run GIMP with batch mode enabled by using the -b option. GIMP Procedure Browser (Cristiano Fontana, CC BY-SA 4.0) Accessing GIMP's batch mode In the Help menu, there is a Procedure Browser with very extensive and detailed documentation about all the possible functions. It took me a while to find the documentation for the full list of GIMP's functions, but it was actually straightforward. ↳ Returns a list containing 1, 2, 3, and 5 Functions and operators are applied to a list of operands by prefixing them: (function-name operand operand. Scheme is a Lisp-like language, so a major characteristic is that it uses a prefix notation and a lot of parentheses. To help you get acquainted with Scheme, GIMP's documentation offers an in-depth tutorial. You can also write scripts in Python, but Script-Fu is the default option. I think Script-Fu is a great way to start because it has an immediate effect on image processing, so you can feel productive very quickly. If you have never used Scheme, give it a try, as it can be very useful. It is an implementation of the Scheme programming language. Script-Fu is the scripting language built into GIMP. ![]() This was the perfect chance to explore them. Although I have been using it for years, I had never investigated its batch-processing abilities nor its Script-Fu menu.
