Work with multiple images

[ouyuanzheng]

I want to use S2P to process multiple images covering the same area, I would like to ask how to set the "roi" parameter in the JSON file. "roi" in the example : "roi" : { "x" : 150, "y" : 150, "w" : 700, "h" : 700 }, how do I get the x and y parameters? What system coordinates are x and y? Can you give me some advice? Thank you so much!
