Overview
EDS-PDF provides modular framework to extract text information from PDF documents.
You can use it out-of-the-box, or extend it to fit your use-case.
Getting started
Installation
Install the library with pip:
Extracting text
Let's build a simple PDF extractor that uses a rule-based classifier, using the following configuration:
config.cfg
[pipeline]
components = ["extractor", "classifier", "aggregator"]
components_config = ${components}
[components.extractor]
@factory = "pdfminer-extractor"
[components.classifier]
@factory = "mask-classifier"
x0 = 0.2
x1 = 0.9
y0 = 0.3
y1 = 0.6
threshold = 0.1
[components.aggregator]
@factory = "simple-aggregator"
The PDF Pipeline can be instantiated and applied (for instance with this PDF):
import edspdf
from pathlib import Path
model = edspdf.load("config.cfg") #
# Get a PDF
pdf = Path("letter.pdf").read_bytes()
texts = model(pdf)
texts["body"]
# Out: Cher Pr ABC, Cher DEF,\n...
See the rule-based recipe for a step-by-step explanation of what is happening.
