Overview

Cardinal can automatically digitize figures (charts, graphs, plots) within documents into HTML format. For each digitized figure, you’ll receive:
  • digitized_html – HTML representation of the chart/graph data.
  • bounding_box – coordinates of the figure location in the original document.
Before Digitization Example: Original Figure After Digitization Example: After Digitization

​
How to Enable

To enable figure digitization, set digitizeFigures: true in your API request.
  • Default: digitizeFigures = false
  • To enable figure digitization, set digitizeFigures = true.
  • ⚠️ Enabling figure digitization will add latency to your requests, since additional processing passes are run.

​
Example Response

The digitized figures will appear in the pages array, with each page containing a digitized_figures array: 
{
  "pages": [
    {
      "digitized_figures": [
        {
          "digitized_html": "<html>...</html>",
          "bounding_box": {
            "x": 100,
            "y": 200,
            "width": 400,
            "height": 300
          }
        }
      ]
    }
  ]
}
Figure digitization is processed alongside other document elements and accessed through the same /markdown endpoint.
