I want create a draggable skeleton made up of connected line segments on an image, then drag the points to the desired location. I've been using imline, but this only shows one line and i have to create it myself.
I would like the lines to show up on the image and then drag the points to where i want them.
In the end i am looking for the resulting endpoints of each line segments which i can get using getPosition.
Any suggestions...

If by skeleton you mean a closed figure, the you can use imfreehand. Creates a draggable & resizable figure. More specifically for connected line segments you can use imrect or impoly. The addNewPositionCallback function will give the latest position values at any instant.

So i tried this. but position variable still shows [0,1500;0,1300] which is my predefined location not the one I dragged to in the image. How can I get that.
figure,imshow(outIm);
l = imline;
setPosition(l,[0 0],[1500 1300]);
postion = l.getPosition();
