  • https://tabula.technology/ this could probably solve your problems using the coordinates of the your particular field you are extracting – aayush_malik Nov 20 '19 at 05:28

You can extract the both images (inline & XObject) and texts (plain and containing PDF operators) from PDF document using pdfreader

Here is a sample code extracting all the above from all document pages.

from pdfreader import SimplePDFViewer, PageDoesNotExist

fd = open(you_pdf_file_name, "rb")
viewer = SimplePDFViewer(fd)

plain_text = ""
pdf_markdown = ""
images = []
try:
    while True:
        viewer.render()
        pdf_markdown += viewer.canvas.text_content
        plain_text += "".join(viewer.canvas.strings)
        images.extend(viewer.canvas.inline_images)
        images.extend(viewer.canvas.images.values())
        viewer.next()
except PageDoesNotExist:
    pass

You can also convert images to PIL/Pillow object and save

for i, img in enumerate(images):
    img.to_Pillow().save("{}.png".format(i))
