Free script: Remove Selected

[varDale_undefined]

Hi all,

I wanted to share a super simple script that creates a checkbox for removing Channels, Paths, Colour Pickers and/or LayerComps allowing a simple interface in case you don't always wish to remove all.

Can someone test on Windows for me

#target photoshop   
//Created by Dale R, for public and commercial use
//global variables
var w = new Window('dialog', 'Batch Remove');
w.preferredSize = [50,100];
w.alignChildren = "left"; // align checkboxes to left
// creating buttons and checkboxes
var ck1 = w.add("CheckBox { text: 'Paths', value: false}");
var ck2 = w.add("CheckBox { text: 'Channels', value: false}");
var ck3 = w.add("CheckBox { text: 'Layer Comps', value: false}");
var ck4 = w.add("CheckBox { text: 'Colour Samplers', value: false}");
var p = w.add ('panel', undefined)
p.alignment = "center";
var btn = p.add('button', undefined, 'Run')
p.add ("button", undefined, "Cancel")
btn.onClick =  function () {
    w.close();
    if (ck1.value == true) {
    app.activeDocument.pathItems.removeAll();    
        }
    if (ck2.value == true) {
        app.activeDocument.channels.removeAll();
        }
    if (ck3.value == true) {
        app.activeDocument.layerComps.removeAll();
        }
    if (ck4.value == true) {
        app.activeDocument.colorSamplers.removeAll();
        }
}
w.center();
w.show();

Is there a way that you can run this script (or a version of it) within an action and selecting certain items but without being promted with the dialogue box every time for each document? I would find it useful to create an action using this script and be able to batch process it over a whole folder of documents that all need paths and alpha channels removed. Thanks!

By @karlssonemil

The script was designed to be interactive with a GUI, intended for use on one active image at a time.

Yes, it is simple enough with a little scripting knowledge to extract the funtions and function calls that you wish to use into a new separate script without a GUI. The script can be recorded into an action for use with automate batch, or extra processing code can be added to the script so that a batch action is not required.

Which paths? Normal paths, clipping paths and/or work paths?

Which channels? Alpha channels and/or spot channels?

I would also love the option to run this without the GUI, is there any chance you could adjust the script so it just ticks all the options automatically? Thanks.

[Stephen_A_Marsh]

Which exact options?

[J--Z]

Every option except the new file one would be fantastic.

Here you go as requested, no GUI... I have not performed exhaustive testing, so use with care and let me know if edits are required... And please do use with care/caution, even more so when batching, the script is obviously "destructive" to non-pixel content and only intended for copies of non-working files.

[J--Z]

Understood! Thanks a lot, been looking for something like this for a long time, very appreciated.

[Pandos]

When i use this in os scripts editor an error ocures at #target photoshop.. what am i doing wrong?

I'm using the os scripts editor but writing in Javascripts..

[Kukurykus]

Get rid of that first line.

[Pandos]

I've tried that, then i get the error: ReferenceError: Can't find variable: app

[Stephen_A_Marsh]

What exact application/program is "os scripts editor"? Sounds like it doesn't know JavaScript.

[Pandos]

i'm very new to this, so sorry for all of the questions and confusion.

I'm using AppleScript 2.7. but i have set it to use JavaScript...thankfull for all of the help i can get!

[Kukurykus]

Did you ran this code script by Photoshop (File / Scripts / Browse)?

[Pandos]

No. i haven't been done that and dont know how.

When i enter the code into AppleScript i get an error message on app not found..

[Stephen_A_Marsh]

Try this:

Downloading and Installing Adobe Scripts

[Pandos]

This is the error message i recive. I have deleted the first line of the code.

[Stephen_A_Marsh]

I believe that you need to use an editor that not only understands JavaScript/ExtendScript – but also understands the Adobe scripting environment as well. As suggested in the other topic thread, for a Mac user I would suggest that you use MS Visual Studio Code for Mac and install the Adobe ExtendScript Debugger extension. Same suggestion for Windows OS, however, the old Adobe ExtendScript Toolkit program still works on Windows (but not on later Mac OS versions) and can be downloaded using the Creative Cloud app (prefs/apps/settings/show older apps).

[Kukurykus]

.scpt is wrong file extension.

[Kukurykus]

I just told you how to do that. After you save your code in .jsx format run it from Photoshop.

[PECourtejoie]

What a work of art!

I have currently no use for such a script, but wondered if a check all/check none button would be useful, given the long list, or maybe a check all per section? (I mean, it is very easy to say as a non scripter)

@PECourtejoie – It's a good and useful suggestion. It is easy enough to preset the checkboxes to be either on or off by default (hard coded into the script with value: true or value: false)... But to offer a checkbox to dynamically check/uncheck checkboxes is much harder for me to do as I don't work with ScriptUI very often.

[PECourtejoie]

I understand, hence the remark in parenthesis.

That said, IMHO, there should be a repository of such code snippets, to create frankenscripts.

[Stephen_A_Marsh]

I finally added a button to Check All checkboxes and Uncheck All checkboxes!

[Kukurykus]

It fails in Multichannel mode.

[Pandos]

Hello hello hello,

some time later and i sat down this evening and got it to work!!!!!!!!!!! i'm quite excited and thank you very much for everything..

I work for a photography studio where we produce a lot of e-com photos with alphas.. is it possible to use this script to remove alphas on a batch? if so.. how? have a great evening or day!!

[Stephen_A_Marsh]

Sure, save the following code as a script and then record the run of the script into an action, then batch the action.

For both alphas and spots:

#target photoshop
app.activeDocument.channels.removeAll();

For only alphas, retaining spots:

/*
https://community.adobe.com/t5/photoshop/remove-alpha-channel-during-a-batch/m-p/11285697
*/

#target photoshop

removeAllAlphaChannelsNotSpot();

function removeAllAlphaChannelsNotSpot() {
    try {
        var myChannel = app.activeDocument.channels;
        for (n = myChannel.length - 1; n >= 0; n--) {
            aC = myChannel[n];
            if (aC.kind == "ChannelType.MASKEDAREA" || aC.kind == "ChannelType.SELECTEDAREA") {
                aC.remove()
            }
        }
    } catch (e) {}
}

            aC = myChannel[n];
            if (aC.kind == "ChannelType.SPOTCOLOR") {
                aC.remove();
            }
        }
    } catch (e) {}
