New Photoshop export script.

tonyc

Hello. I've been fiddling around with the export script for Photoshop. 😃

Here's the new script:

EDIT: updated to make the ruler origin optional.

EDIT2: added export directory name option.

EDIT3: fixed ignore layer bug, added "-NOSKIN" tag option, added loading and saving of options.

EDIT4: my bad! needed try / catch block around getCustomOptions when no previous settings exist!

 
 
// This script exports photoshop layers as individual images.
// It also write a JSON file that can be imported into Spine
// where the images will be displayed in the same positions.
 
// Settings.

var saveJSON = true;
var ignoreHiddenLayers = true;

Where's the default origin position of the rulers? upper left?

tonyc

Yeah.

I guess I could put another checkbox in the dialog to revert to the normal behaviour? (new behaviour default off?)

🙂

Pharan

Good call. I like it.

(I learned how to set the ruler origin just now. And since you mention it in the checkbox, people can naturally check what that is and how to set it to take advantage of the feature.)

Søren

Good stuff 🙂 I'll take a look at it later and if I like it with the rulers I might include it in the official script if you're ok with that?

tonyc

Yeah no worries.

EDIT:

Added option to specify export directory name. Again.. Use it if you want. 🙂

Pharan

This is also a good feature. 😃

Hello guys!

Today I noticed that when I uncheck "Ignore hidden layers" in the photoshop scrip it doesn't stop ignoring them. Does anyone know if I'm doing something wrong?

Thanks!

Søren

Haven't had time to look into the script yet.
If there are any problems with ignoring layers I'll get that fixed as well.

tonyc

Hello.. I've updated the main post with my latest version.

I found the ignore layer bug and fixed it.

The latest version checks if the layergroup / folder name in Photoshop has a "-NOSKIN" tag in it and doesn't create a skin for that layergroup / folder. It's handy for keeping your Photoshop files in order and not having millions of layers in the root of the doc.

Also, the script will now remember what your options were last time round and use those.

Use it if you want.

Enjoy!

Pharan

Thanks so much for you work on this, tonyc! It's a huge help!

-NOSKIN tag?

Beat me to doing this 🙂

-NOSKIN tag?

Aye, just include the string -NOSKIN (minus no skin) on the folder name in your Photoshop project and the layers within won't be made into skins.

e.g. I have the layers "leftarm" and "rightarm" in the folder "arms-NOSKIN". The slots "leftarm" and "rightarm" are exported to the "default:" skin instead of "arms:" because of the -NOSKIN tag. I haven't fully tested skins inside -NOSKIN folders yet so BEWARE! :o

Søren

Cool that you keep updating it 🙂 Not completely sold on the -NOSKIN tag yet though. I would love to update the script for Adobe CC and then use HTML5 to give it a proper looking panel and some buttons to add/remove tags etc. But unfortunately I don't think it will work in older versions of Photoshop then.

Pharan

This version gets an error "Error 1302: no such element" in Photoshop CS5 on line 27:

var exportSettings = app.getCustomOptions(settingsID);

I think the same code is also in line 363.

I don't think Photoshop CS5 can remember previous settings, or the API changed.

UPDATE:
I used the version with the try-catch block. Seems to work fine in CS5 now. Maybe that was the problem.

By the way, do you want to put this on GitHub as a GIST?
https://gist.github.com/

So we can branch and fork and stuff and people can choose the version that works for them while we can still track changes and bugs?

Søren

Unfortunately Nate manages the git stuff, I'm sure he can put it up when he is back from vacation.

Hello,

any chance to get a working export script for Photoshop CS6?

Søren

The script works for CS6 that's what I wrote it for.

totoe33

Any chance to get this script. i tried the pasted one and its not working for me.
maybe i put it wrong into photoshop or give it a wrong extension.
thanks.
