How to get the path point data From JPEG or JPG files

[Mahesh12]

Hi all,
I have .jpg file which contains path point or vector path.
So where that pathpoint details are stored, and how to get that path point data from the path panel

in the above image jpg file contains 6 paths in it so how to get that.
Thank You

Do you just wish to copy all paths from one file to another? Such as all paths from a JPG to a PSD? Or something else?

What exactly do you wish to do with each pathItem in the pathItems collection?

Or are you specifically after lower level details such as pathPoint, pathPoints or pathPointInfo?

You labelled the post as both actions/scripting and SDK. Can you clarify, as programming in the SDK is very different.

@Stephen Marsh  i want to store that path point details in a file

Ah, I have never done that!  :]

The information is available in ESTK Scripting both via DOM and AM. (Edit: … for open files that is.) 

So as @Stephen Marsh already indicated it would be important to know what you are actually trying to achieve.

@c.pfaffenbichler can you help me with scripting

I omitted the Bezier Handles as you only seemed to speak of pathpoints.

As the others mentioned, scripting can get the info. You can store the info in an array. It will record the points in the orthat they were drawn. 

I'm curious as to how a jpg file has path info stored? I thought that wasn't possible.
