Sample Results JSON

Name Type Description
original_width number width of the original image (px)
original_height number height of the original image (px)
image_rotation number rotation degree of the image (deg)
value Object
value.points Array.<Array.<number>> list of (x, y) coordinates of the polygon by percentage of the image size (0-100)
