How to display vertex coordinates of Polygonal Lasso Tool?

I use Polygonal Lasso Tool to form a selection like the screenshot below:

Now I want to record the accurate vertex coordinates of the Polygonal Lasso Tool. Do you know how to display these coordinates somewhere in Photoshop so that I can record them manually in a notebook or automatically as a file? Thanks a lot.

PS: I'm using Photoshop CC 2019 on Windows 10.

The price is a bottle of red wine don't go overboard a $15 bottle will do.

// enable double-clicking from Mac Finder or Windows Explorer

#target photoshop // this command only works in Photoshop CS2 and higher

// bring application forward for double-click events

app.bringToFront();

// Save the current preferences

var startRulerUnits = app.preferences.rulerUnits;

// Set Photoshop to use pixels

app.preferences.rulerUnits = Units.PIXELS;

var thePath = selectedPath();

if (thePath == undefined) {

   alert("No

You may be able to write a Photoshop Script to do that. The script would have Photoshop convert the selection to a Path them process path to get the control points coordinates. There may be  extra points the script could also  write the path to a log file. Set guide line marking the points so you can read them on the rulers and switch between ruler unites  just record the point you want in the unites you want. A path can have many points a list may not fit on your display.

@JJMack: Thank you. I have no knowledge of writing script in Photoshop and my time budget does not allow me to study it. Could you please share your script with me? I can pay you for the script.

Do you have a lot or a few of these to do?

Would it work for you to:

  • Convert your selection to a path in the Paths panel
  • Open the Info panel
  • Select an anchor point with the Direct Selection tool (white arrow)
  • Copy the info from the X and Y

@JJMack: Thank you so much for the script. May I ask one more question: I saved the script into C:\Program Files\Adobe\Adobe Photoshop CC 2019\Presets\Scripts\ShowCoord.jsx. This script now shows up in menu File -> Scripts. Then I initiated the Polygon Lasso Tool and made a selection. But when I clicked the menu to run the script, I was given a message "No Path Selected". I tried to call the script via File -> Scripts -> Browse ... but got the same alert. I checked the script and found it is because line 12 returns undefined. I guess the script thought the selection is not selected (or activated), but it is indeed selected:

Could you please tell me how to use the script correctly? Thank you again.

Open the path panel and click on the icon in the bottom to convert the selection to a path the message states you have no path.
