Basically I would like to know how to handle the image atributes like "Drag & Drop" ..how to float over an another images and How can read and set their X and Y position...
I would like to have the chance of choose one of two or more marks or symbols and drag them to one specific area where there is a background image to point something in particular and save the X and Y position of each mark. So any user can load those records later and display the marks at the same position so they can understand the meaning of those marks.
Is there a tutorial for that?
I would do something like the image below
Thanks ..Have a nice day
