We'll need to add some more features to our class definition so that we can extract meaningful, aggregated blocks of text. We'll need to add some layout rules and a text aggregator that uses the rules and the raw page to create aggregated blocks of text.
We'll override the init_device() method to create a more sophisticated device. Here's the next subclass, built on the foundation of the Miner_Page and Miner classes:
from pdfminer.converter import PDFPageAggregator
from pdfminer.layout import LAParams
class Miner_Layout(Miner_Page):
def __init__(self, *args, **kw):
super().__init__(*args, **kw)
def init_device(self, resource_manager, **params):
"""Return an PDFPageAggregator as a device."""
self.layout_params = LAParams(**params)
return PDFPageAggregator(resource_manager, laparams=self.layout_params)
def page_iter(self):
"""Yields a LTPage object for each page in the document."""
for page in super...
