using labelme for create an annotation file in coco fromat for pose estimation

[alaa-shubbak]

I don't have any exact error yet.
i just want to know the format of json i got
for point annotation , it gives the (x,y) couples
for rectangle annotation, it gives me those:

{
     "label": "xxxx",
     "points": [
       [
         199.15119363395226,
         15.411140583554383
       ],
       [
         461.4854111405835,
         263.9522546419098
       ]
     ],
     "group_id": null,
     "shape_type": "rectangle",
     "flags": {}
   }

what does the 1st point and the 2nd points mean. is it the top-left and bottom-right corners (points)? or depends on the points that i already created. (the clicked positions)
just to be sure .
thanks
