Hi,

I purhcased and watched the artist workshop. there was a cool script there for exporing a layer. Can you guys please, please please make it available, or tell us how to do it?

I'll make the script available when I get home tonight 🙂

I'd love to check that out too. Thanks Shiu!

yeah, that'd be awesome..

I'm close - but I can't get it to give me the layer name when I save it.. a lot of alt-tab and F2 going on here 🙂

What are the quirks? Does the script run quickly?

As quick as my programming skills allow it to be, it does suffer from having to loop through quite a lot of layers. The main "quirk" is that you can't export multiple layers that are grouped together as a single layer, they will have to merged. I'm sure that a more programmer savvy person could improve it. Maybe a natively written plugin would be the best option, but that's way beyond my skills.

It's still FAR faster than doing it manually though when bound to an action.

Unless you are doing actions that are unnecessary, the speed is likely limited by Photoshop. Not sure what you mean by the bold part in "can't export multiple layers that are grouped together as a single layer, they will have to merged". You can have a number of layers in a group, but they are still separate layers. You want them to be merged and exported as a single PNG? Not sure everyone wants that, in which case I guess the script is fine as is. I cleaned up the syntax a little and will put it in the launcher the next time I have to rebuild it.

Yeah the speed is definitely limited by photoshop, looping through the layers changing visibility is very slow unfortunately. Sometimes you want to export multiple layers a single PNG by adding them to a group, that's what I was talking about 🙂 Then you can use adjustment layers without having to merge first. So if the selected layer is a group exporting the PNG should take that into account, if not it should export as it normally does.

But don't you use groups for general organization? How would the script know that some groups should be merged and others traversed and a PNG output for each layer in the group?

Shiu, how does your script compare to Photoshop's built in "Export Layers to Files"?

I find it to be much faster and it allows you to select a single layer and export it instead of all layers every time. I use a combination of an action where I scale the image to a preferred size and with a layer selected I hit F5 then it writes out the PNG and reverts it back to its original size.

I actually had my own action which is much quicker - I duplicate the selected layer, apply mask, copy all, file new, delete the background and save it, closed, doc, delete the original layer.. that's lightning fast. I didn't know about the script recorder, so I didn't know how to do all that with the doc file name : but now I do. I'll post up my resulting script shortly.

Yeah that is a faster way of doing it. One downside to that is if you use adjustment layers which I rely heavily upon. I do have an idea for how to possibly do it faster though. Basically all layers except for the selected one and adjustment layers could be merged into a single layer which could then be hidden. This would be much faster since changing visibility is what takes time.

Enclosed is my version of the script.

For those of you who don't have spanish computers, you'll need to change "Fondo" on line 93 to "Background" or whatever it is in your language.

Thanks for the headsup on adjusment layers. I'm gonna make a version of the script whereby you can select all the layers your interested in first , and it will merge them down then do the same thing with that.. that'd be quick too..

Other variations could be all layers in a folder.. I'm not an artist, so I'll just have to keep working up tweaks for my artist as and when she needs them..

Script is in plain text..

ps
code is verbose becuase I recorded it... http://blogs.adobe.com/crawlspace/2006/ ... and_1.html

Remember to disable the recording script again, it will slow down lots of things in photoshop 😉 thanks for sharing

good call 🙂 thanks.
