hi all,

here in the channel i have selected Path 1 as shown in above fig. and after that i'll select the option "Load Channel as selection".

the above fig. shows the option which i have choosen.

after selecting the option "Load Channel as selection. the dotted line i appeared around the alpha channel.
is there any script to retrieve that pathpoint.

the above fig. shows the dotted point after selecting load channel as a selection. i want retrieve those dotted line path point .. is there any script to retrieve that details..

Thank you

Correct answer Stephen Marsh

var doc = app.activeDocument;

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

var idslct = charIDToTypeID('slct');

var desc1 = new ActionDescriptor();

var idnull = charIDToTypeID('null');

var ref1 = new ActionReference();

var idChnl = charIDToTypeID('Chnl');

ref1.putIndex(idChnl, i + 1);

desc1.putReference(idnull, ref1);

executeAction(idslct, desc1, DialogModes.NO);

var desc = new ActionDescriptor();

var ref = new ActionReference();

ref.putProperty(charIDToTypeID('Chnl'), charIDToTypeID('fsel'));

desc.putReference(charIDToTypeID('null'), ref);

var chnlDesc = new ActionReference();

chnlDesc.putIndex(charIDToTypeID('Chnl'), i + 1);

desc.putReference(charIDToTypeID('T '), chnlDesc);

executeAction(charIDToTypeID('setd'), desc, DialogModes.NO);

doc.selection.deselect();

}
i have this code it will loop each channel and select and after selection it will deselect current channel and after that it will select next channel..
can u provide that create vector path for selected channel/path

This code will loop over each alpha channel (ignoring colour channels or spot channels), and create a path from the channel selection (you can adjust the tolerance from 2.0), named after the alpha channel. It doesn't remove existing paths of the same name and it obviously doesn't compare the path name to the channel name or do the other things that you mentioned.

It's currently a selection, so please clarify:

Do you want to convert a selection into a Vector path in the paths panel via scripting...

Or do you wish to load the channel as a selection via scripting...

Or both?

P.S. I'm also curious about the channel names, we're these made from paths? If so, are the paths in the current document or another?

Known Participant

yes those made from paths and in the current document. yes i want to do both via scripting. and through scripting, from path1 to path 8 from channel panel for each selected, i want create vector path in the path panel via scripting

Forgive the question, but if the channel is made from a path selection in the current document, the path already exists - so why save it as a path again?

Or have you modified the channel and now wish to have a new, modified path "matching" the channel edits?
