Don't know about a script but G'MIC has a filter called Extract Objects found under Arrays and Tiles
I just tried it...not done so before. Will extract the pictures onto different layers

It just squares them tran to make them all the same which I guess is what a script would do
I have attached the extracted picture so you can see what it does.

Attachment:

megaman7.xcf

How would you automate that though? it sounds difficult to me.
There are other applications that are built just to do that.

I have no idea (you're the script writer

) I also noticed it extracted two together where they were almost the same size as one.

If you want to know ask David...He wrote this filter.

Oh there's already a script. Great, then I don't have to bother with it then.

@Nixnine:
I think the script you're after is DivideTransBG.scm by Rob-A available here:

For the sprite sheet you posted above, you will first need to remove the white background (unless you intend to put the separated sprites back onto white backgrounds). I find that Select-by-color with threshold about 4.5 does the job cleanly.

I downloaded and tried the script from this post. I think it must be for v2.6 as I got absolutely no results.

I cleaned the background first and did alpha to selection before trying.

Attached is the xcf file with the bg removed.

Download from Rob's site:
http://www.silent9.com/incoming/scripts

click on DivideTransBG.scm and save to your personal scripts folder.
It works fine for me both on Gimp 2.8.14 and 2.9.1

I must be doing something wrong. I still get no results with the download from the link in your post. Please post an image of the settings you used.
Thanks.

I just left the defaults and changed "Maximum items to isolate" to 100.
and i a new image of 47 separate layers.

Well then here's an image of my settings. I have no output. Did you do alpha to selection of the image of the megamen?

@Oregonian:
I think you must have auto-cropped the image before running the script and it doesn't like that - it needs a bit of transparent border around each sprite.

[ Image ]

I didn't select anything... i just copied the megaman image from the post and pasted as new image in gimp and ran the scripts with defaults and it worked.

Ah! That worked! I added more canvas to the image.

Finally! Thanks! :jumpclap
