Sorry. i can't answer your question. But, you maybe answer my question.
How can i take snapshot of whole layout not just window?
If my layout size is 2480*3508 and window about 600*800. How can i produce snap of whole layout dimention with 2480*3508. I can take snap of window size means just the viewed section. But, i need whole page in exact pixel & size(2480*3508)
