saving layer-masks as jpgs

[oeschen]

Hey all,

I am looking for a solution to extract all the masks in a .psd file into single "normal" jpgs or tiffs.
For example: if a psd has 30 layers and only 10 of them have a layer mask, the script should be able to save all 10 masks into 10 single files. Would it be possible to integrate it into a Batch process, where I can apply this to several files?
Does anyone have a suggestion or idea?

Thanks in advance!!

I think Image > Calculations (set to Result > New Document) might provide a quick way to get a new file, at least I think it should be faster than copy/pasting.
Unfortunately ScriptingListener.plugin seems to record this with names, so the code should be amended for index instead to avoid issues if more than one Layer or more than one open Document have the same name.

Edit: Does this help?

Interesting idea, but somehow it does not work for me when I try using it. I have CS6. Did you apply the scipt on an open file without selection the layers?

I get the following error:

Error 8800: General Photoshop Error occured. This functionality may not be available in this version of Photoshop.
- The command “Select” is not currently available.
Line: 12
-> executeAction(cTID("slct"), desc, DialogModes.NO );

Am I just using the "wrong" version of PS?

Thanks for helping out here!
Cheers

As
Code: Select allexecuteAction(cTID("slct"), desc, DialogModes.NO )
does not seem to be part of the code I posted I have to wonder what you are doing.

Anyway, this is an amended version.

WOW!!!
Such great work. Not sure why I had issues with the first script but the second you sent works great!!
Big thanks from Berlin!
