Script to rip apart spritesheets and save them individually as pngs

Hey all you amazing scripters,

I have a spritesheet with varying sizes of sprites all on 1 layer. I am wanting to automatically split them up into different layers and then quick save the layers as a png.

I’ve been able to do this manually with actions if they’re the same size or smaller than a defined amount but can’t seem to make them work if they’re different. It seemed that a script would make this way quicker and more efficient.

The sprites will all be separated by varying amount of space, so nothing will be touching. If It doesn’t change anything, the sprites will have a few pixel drop shadow but will still not be touching other adjacent sprites. If that makes the script more difficult because of opacity in the shadow, it can be removed.

Hopefully someone is able to help! I’ve googled extensively and there are a lot of tools that do this but none seem to work on varying sprite sizes. Any and all help is appreciated. Thank you for your time.

The picture I posted was an example. My sprite sheet has no background and transparency around all sprites. The sprites are varying sizes and shapes, and aren't all on the same axis so none of the posted solutions will work. This (linked above) script works nearly perfect but as I already mentioned skips over things randomly and duplicates some layers. I guess I will just have to make do. Thanks.

Yes that script normally create many more layer then you want. It seems to make a layer for any little spec in the raster layer that is surrounded by transparency. It does not know a spec is not one of your sprites. I think if you want an automated process you need to create you sprites sheet in a more organize fashion like in a grid so the sprites can be isolate automatically and layer created. It sound like you would need some AI program that can recognize what is and what is not a sprite in your current sprite sheet. Where Sprites are various sizes in random random locations that can hold a hold a sprite you create.

An Interactive action where the user would be required drag out guide lines so the action could use a script to dice up your sheet can be recorded to create layers then create an animated gif that would look like this. The Frame layers can be saved out as png24 using menu File>Exoprt>Layers to Files... .

Here is an example spritesheet from google so any potential scripters know what I mean. I want to split each image into separate layers and then export them as a png.

I thought of this one, however, it will not be suitable:

Not exactly what I was looking for but I used it for a few hours. It seems to be very buggy and saves the layers at random (skips over things) and then saves a lot of duplicates. Thank you for the thought and I guess if worse comes to worse I can use it.
