You can use scripting to derive coordinate info, but you really need to explain in much more detail what exactly you need. Anyway, ask in the respective AI scripting forum.
as Mylenium has stated, we need much more info.
Exporting to a png and pdf is no problem.
but what coordinates do you want, and where do you want them?
what is the end usage?
there are many options for saving files. resolution etc...
come back with a rundown of what you need and we can have a look for you.
@Mylenium Thanks for your reply.
We just want blueprint of our UI screens specification, Like XY coordinates , Text specification, Touch area specification(width & height of touch area) for illustrator. We explored Specctr but its says but still there the XY coordinates for only on Top left, and not possbile for grouped objects.
