Code:

(newWidth (car (gimp-image-width image)))
(newHeight (car (gimp-image-height image)))

That makes sense. Unfortunately, I'm still getting the same error with this:

Code:

(define (script-fu-scale-half image)
    (gimp-image-undo-group-start image)
    (gimp-selection-none image)
    (let*
        (
            (newWidth (car (gimp-image-width image)))
            (newHeight (car (gimp-image-height image)))
        )
        (gimp-image-scale image (/ newWidth 2) (/ newHeight 2))
    )
    (gimp-displays-flush)
    (gimp-image-undo-group-end image)
)

Edit: I wish I knew why, but it inexplicably started working without me changing anything (as far as I can tell). It works now!

Did you refresh the script (or restart Gimp)?

I thought I had (filters>script-fu>refresh scripts), but maybe I had missed it.
