Photoshop Script to continue work path

  • December 9, 2018

Hello everyone,

I opened a document that already had a path, and then I select the path from the "Paths" window:

and it is shown on the canvas:

I want a script that will continue the current path so I can close the path. (sometimes the path will be somewhere else so I can't rely on exact X,Y position)
I want something like this for example:

that's it.

Try this. Works in CC2018. In CS6 does not work.

var len = app.activeDocument.pathItems.length;

    var zoom = get_doc_zoom();
    set_doc_zoom(100);

But it should be possible to auto-complete the open subPathItem if there are clear and unequivocal rules about how it is to be completed.

    r-bin​, c.pfaffenbichler​ thank you for your replies. I'm on the way to solve it, I made a new path, and recorded the last anchor point in an action, I played the action afterwards and it said "Pick-up Path"

    I think I have 2 ways to go from here (i need help to execute each one of them since I don't know how)

    1. find a script to "Pick-up Path"

    2. I've recorded the last anchor point in an action, if I could record the last anchor point and somehow save it for later, for example: write the X,Y position into the Metadata and later delete it, it should work, only question how I record the anchor point or the last anchor point

      Do you want to activate (select) the last point in the Path?

      If so, then I tried to do this in CS6 using the code obtained from the record of the PathSelectionTool action. It works extremely unreliable and I abandoned this idea.
