I would likke to find the image ID from a Scheme script.

(gimp-image-list) run in the Scheme console returns e.g. (1 #(5)) so I know from this that the image-id is 5, but if I have multiple docs open I may get the return value (2 #(8 5)). So how do I find and pass the correct image ID to a Scheme variable inside a script? E.g. (let* ( (img (cadr(gimp-image-list))) ) img ) now returns #(8 5).

I believe the function needed may be (gimp-item-get-image item), but how do I find the item-ID and assign it to a variable?

Any help is appreciated.

Thanks

I found the answer. Not sure why it wasn't working when I first tried it.

Still don't know how to get the item id as required by (gimp-item-get- image item) function.

There are quite a few functions that require 'item' as a parameter. The procedure browser says: 'item ITEM The item' which isn't very helpful, but in actual fact I don't need it. I have an idea why the script initially failed, and it is fixed now and working fine.

Subj: Re: [Gimp-user] Scheme - image ID

I'm puzzled what you're trying to do because it seems you're going

about this backwards.

You would usually know the item ID because you know which image it's

associated with, so wouldn't need to find the image that the item is associated with.

For example to get a layer-id, you'd have to know which image it's in,

using: gimp-image-get-active-layer

You said you found the answer then your last statement seems to

indicate you

haven't.

Apart from the previous suggestions on how to find the image ID I had another thought. If you are writing a script where you want to right

click

an image and run your script from the menu that will pop up you can

set up

your script so the image ID and drawable ID are automatically passed

to your

script.

In the script-fu-register block where you have the list of SF-*

parameters,

you add two lines right before any other SF-* parameters: SF-IMAGE "Image" 0
SF-DRAWABLE "Drawable" 0

In the define for your script you would add "image" and "drawable" as

the

first two parameters expected by your script. You can use any variable

names

you want in place of "image" and "drawable".

If your define was (define (my-script-fu-script param1 param2) you would change it to
(define (my-script-fu-script image drawable param1 param2)

The variable name "image" will automatically be set to the ID of the

image

that you right clicked.

Subj: Re: [Gimp-user] Scheme - random foreground colour

Try

(list (rand 255) (rand 255) (rand 255))

for example: (gimp-context-set-foreground (list (rand 255) (rand 255)

(rand 255)))
