Capture Information with Vision API

[Oluwafemi Balogun]

Attached is a screenshot from Vision API. The intent is to be able to select a single block to capture the content of that selected block. We are avoiding to read directly from the accompanying json file since it gives information for all the blocks/image but be able to generate appropriate json for the selected box only. Currently, the accompanying json gives output for the entire image, block by block, but we need only have the json for the block selected by user. Would appreciate feedback on how best to go about achieving this. Thanks.

According to the Vision API docs, each response block has a set of related vertices, like the following:

        {
          "description": "ABBEY",
          "boundingPoly": {
            "vertices": [
              {
                "x": 45,
                "y": 50
              },
              {
                "x": 181,
                "y": 43
              },
              {
                "x": 183,
                "y": 80
              },
              {
                "x": 47,
                "y": 87
              }
            ]
          }
        },

You'll need to capture the point that the user clicks and cycle through each block to see whether the point is within the block's boundaries.
