# Interactive job example
# PDF rendering using poppler and pdf2image
# It will render each PDF page to a pageXX.jpg file

1. From speed-submit: salloc --mem=1Gb
2. Create conda environment:
   2.1 conda create --prefix /speed-scratch/$USER/poppler-venv python=3.8
   2.2 conda activate /speed-scratch/$USER/poppler-venv
   2.3 conda install -c conda-forge poppler
   2.4 pip install pdf2image
   2.5 pip install poppler-utils

3. Create python script.

Python script:
from pdf2image import convert_from_path, convert_from_bytes
from pdf2image.exceptions import (
    PDFInfoNotInstalledError,
    PDFPageCountError,
    PDFSyntaxError
)


# Store Pdf with convert_from_path function
images = convert_from_path('./pdf1.pdf')

for i in range(len(images)):

      # Save pages as images in the pdf
    images[i].save('page'+ str(i) +'.jpg', 'JPEG')

4. Execute the script: python script_name
5. If any rendering error is shown, check if the PDF is composed correctly:
   5.1 pdfinfo pdf1.pdf
