          Hit Cmd + T to get the transform controls. The control bar up at the top will have the x and y values.

            You may have to explain what you really mean.

            Do you rotate/otherwise transform Layers/Smart Objects/Shapes/… and in which form do you need the coordinates afterwards?

             

            By default Photoshop files’ zero-point is the upper left corner by the way.

              Hi pfaffenbichler,

               

              Thanks.

               

              I want to know about the exact x, y positions of every break points. These values should be given to the scripting side. When i export the trimmed image (png image) its appear square or rectangle shape, because i can't export exact shape of that specified object. So i need to tell every vetice points x,y positions. Here i attached the sample image.vertex_points.jpg

                So you are talking about Paths with corner points without Bezier handles?

                Are there multiple Paths or inly ever one per image?

                 

                Getting PathPoint information can be done with a Script as well as creating a txt- or some other file, you may want to ask for help over at

                  Thanks for your reply.

                   

                  Exactly! I want photoshop scripting for generate values of path position.

                   

                  Thanks

                        By the way: That Script only processes the last Path in the Paths Panel (because if a Shape Layer is selected its Vector Mask appears at the end of the list), if

                        • there are more than one Path or

                        • you want the active Path or

                        • …

                        you may have to adapt the Script.
