This Orton Effect looks good - I found some very interesting links,

I’ll steal your Orton Plugin and try to rewrite it. Some things are different to the program on the Gimp site - I have to find out why.

I love XKCD - here is the comic Carlos mentioned.

In spanish, there’s a good ressource for learning python-fu in javie’s linux blogsite (python-fu for non-programmers), aswell as some nice scripts to download.

Btw, this comic stripe shows why Python is so confortable and easy to learn XDD

Sorry for putting so many links in this comment, i think it is interesting to share this things, and i’m not a spam bot

In fact, you will find that the GIMP-Python scripts start with the line !/usr/bin/python . The GIMP extension is loaded with the familiar import command.

Another point of difference between GIMP-Python and Script-Fu is that GIMP-Python stores images, layers, channels and other types as objects rather than just storing their ID. This allows better type checking that is missing from Script-Fu, and allows those types to act as objects, complete with attributes and methods.

Also, GIMP-Python is not limited to just calling procedures from the PDB. It also implements the rest of libgimp , including tiles and pixel regions, and access to other lower level functions.

You are on the spot with being “comfortable”. I think I’ll be that more with Python than with Scheme because I have some background in OO.

Thanks for the further input on Scheme - I see that it is a very logical and strict language- And easy to program in if you have internalized the concept but difficult to understand if you haven’t. A bit like FORTH - I once learned that too.

I am not sure how far I can or want to go into writing plugins. And how to make a video out of it. If I do it I’ll keep Scheme on the screen - and threaten now to ask you for further advice.

is right in that parentheses hilighting in an editor is helpful. But your count got off in that the end of the program not only encloses the ( from the start, but also the ( from the let statement.

(let ((var1 exp1) (var2 exp2)) body) sets up en environment where the expressions are bound to the local variables. This binding of name to expression holds throughout the body of the let.

Lastly, values are returned in script-fu in the form of a scheme list. (car list) returns the head of the list so

(let ((pop-base (car (gimp-layer-copy drw TRUE))) …

says start an environment in which the variable pop-base is assigned the value of the head of the list returned from calling function gimp-layer-copy. Phew!
