Hi,

I'm currently trying to write a Script-Fu (actually my first one), but although I found several online tutorials on how to go about, I'm still not sure of the proper syntax for most of the steps I would like the script to perform. This is basically an advanced 'Unsharp Mask' I have been doing manually so far, but since I need it very often, would like to make a Script-Fu for this.

There are other scripting language interfaces available. Python (which I prefer myself), Perl, Ruby, and Lua scripting are all available, Python is more standardized than the others. If you have experience with one of those, I suggest to use that language instead.

Personally I think almost any language other than Script-fu is a better choice. I've got quite a wide range of experience with different programming languages myself, but when I try to work with Script-fu/Scheme/LISP, writing anything but the very simplest of procedures invokes great frustration in me.

I've included an attachment (plain text) which contains some of code fragments which correspond with the steps you described (your steps are the lines starting with ";-" ). I left out the standard stuff such as registering your script, declaring your variables, and handling UNDO.

Hello,

I'm new with scripts-fu too. I've had an eye to your script and I saw a lot of " (set! ". I thought that it doesn't work any more with TinyScheme. (cf. http://www.gimp.org/docs/script-fu-update.html)

Regards.

The code I attached to my previous post had a mistake on line #24 which should have been:
(set! layer (car (gimp-image-get-active-layer value-image)))

I also should have used 'hue-image' and 'sat-image' when I later called 'plug-in-compose' (the code I had functioned fine, it just might be a little confusing).

You still can (and will) use 'set!' in your scripts; but you need to create the variable first. Previously, the variable would be created automatically if it did not exist.

I did not properly present the part about pasting the recomposed image back into the original layer. You will want to set the offsets of the pasted layer so that they match the original active layer ('drawable') and to also anchor your pasted layer. The code should be similar to the following:

(set! floating-sel (car (gimp-edit-named-paste drawable buffer-name TRUE))) (gimp-layer-set-offsets floating-sel (car (gimp-drawable-offsets drawable)) (cadr (gimp-drawable-offsets drawable))) (gimp-floating-sel-anchor floating-sel)

Allright, thanks for the information.
