Re: [Gimp-user] Re: RGB to BGR script works, but how to run autolevels?
I have it down to the following (although I'd still love an autolevels ;-), is there any way to pass a list to gimp-image-delete, because I've tried several things and I always get invalid argument. I tried: (g-i-d new-image-rgb) (g-i-d (new-image-rgb)) (g-i-d '(new-image-rgb)) Must be something I am misunderstanding about lists. Basically trying to slim the three g-i-d's down to one statement. But I did reduce the decompose to one statement with lists (I suspect it's much faster now but I haven't really timed it) and removed some cruft from the script I started from that I didn't need.. (define (script-fu-irchannelswap inImage inLayer) (set! new-image-rgb (plug-in-decompose 1 inImage inLayer RGB)) (set! new-image-bgr (car (plug-in-compose 1 (caddr new-image-rgb) inLayer (cadr new-image-rgb) (car new-image-rgb) (car new-image-rgb) RGB))) (gimp-display-new new-image-bgr) (gimp-image-delete (car new-image-rgb)) (gimp-image-delete (cadr new-image-rgb)) (gimp-image-delete (caddr new-image-rgb)) (gimp-image-set-filename new-image-bgr (car (gimp-image-get-filename inImage))) ) (gimp-displays-flush) (script-fu-register script-fu-irchannelswap Image/Script-Fu/Enhance/IR Channel Swap Channel Swap Walter Francis copyright 2003, Walter Francis 2003-08-30 SF-IMAGE The Image 0 SF-DRAWABLE The Layer 0 ) -- Walter Francis http://theblackmoor.net Powered by Red Hat Linux 9 ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

I figured there was a better way, but this is my first one, so I was doing what was obvious (and simple :) I made one other small change, grabbing the filename so the path and filename was right to save the changed picture, and I experimented with a progress bar but it didn't work quite right.. I'll experiment some more with all that, and might try using a list for the above. I tried RGB once but only got the Red, so that's why I split 'em up, a list would be more effecient.
