Convert and visualize text bounding boxes

In this example we will use the output of the converted document and create an image of elements detected on each page.

System dependencies

This script is converting a PDF document with Deep Search and exports the figures into PNG files.

The PDF to image conversion relies on the pdftoppm executable of the Poppler library (GPL license) https://poppler.freedesktop.org/ The Poppler library can be installed from the most common packaging systems, for example

• On macOS, brew install poppler
• On Debian (and Ubuntu), apt-get install poppler-utils
• On RHEL, yum install poppler-utils

Notebooks parameters

The following block defines the parameters used to execute the notebook

• INPUT_FILE: the input PDF to converted and analyzed
• SHOW_PDF_IMAGE: if enabled, the background will contain the rendered PDF page
• SHOW_CLUSTER_BOXES: if enabled, the cluster boxes will be visualized
• SHOW_TEXT_CELLS_BOXES: if enabled, the PDF raw text cells will be visualized
