Changing Selected Channels' channelType

[Ben_Lindsey]

Hello Everyone,

I've been trying to run the following script on only the channels I currently have selected. However, no matter what I put in, I cannot get it to run on only those channels I have selected. Can anyone help? I'm sure it's probably the simplest thing but I've been pulling my hair out over this.

var doc = app.activeDocument;

for(var channelIndex = 0; channelIndex<doc.channels.length; channelIndex++){

    if(doc.channels[channelIndex].kind == ChannelType.MASKEDAREA||

        doc.channels[channelIndex].kind == ChannelType.SELECTEDAREA){

        doc.channels[channelIndex].kind = ChannelType.SPOTCOLOR;

    }

}

You are running the script on all channels not selected channels, example of selected channels.

var alist =  activeDocument.activeChannels;

for(var a =0;a<alist.length;a++){

    $.writeln(alist.kind + " " + alist.name);

    }

SuperMerlin​ Thank you so much for the guidance! I've changed it using your suggestion and it's working now. The process seems to take a bit long but it's working as expected.

var doc = app.activeDocument;

var alist = doc.activeChannels;

for(var a = 0; a<alist.length;a++){

    if(alist.kind != ChannelType.SPOTCOLOR ){

        alist.kind = ChannelType.SPOTCOLOR;

    }

}

Does your suggested script also rename the selected channels in sequential order?  For example, could I use that to append '01', '02', '03' and so on sequentially to the beginning of the channels while keeping the channels' existing names behind the numbers?

Yes..

var alist =  activeDocument.activeChannels;

for(var a =0;a<alist.length;a++){

    alist.name = "0" + (a+1)  + alist.name;

    }
