A lightweight Elixir library for extracting text from PDF files using Python's `pdfplumber`. Supports single and 
multi-page extraction with optional area filtering.

## Features

- 🔍 Extract text from single or multiple PDF pages
- 📍 Area-based extraction using bounding boxes
- 🐍 Leverages Python's powerful `pdfplumber` library
- 🚀 Simple and intuitive API
- ✅ Comprehensive test coverage
- 📚 Full documentation

## Installation

Add `pdf_extractor` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:pdf_extractor, "~> 0.2.1"}
  ]
end
```

Then start it in your application start function:

```elixir
defmodule MyApp.Application do
  use Application

  def start(_type, _args) do
    children = [
      ...
    ]

    PdfExtractor.start()

    opts = [strategy: :one_for_one, name: MyApp.Supervisor]
    Supervisor.start_link(children, opts)
  end
end
```

## Usage

Extract text from specific regions using bounding boxes `[x0, y0, x1, y1]`:

```elixir
pages = [0, 1] # zero based index
areas = %{
  0 => [0, 0, 300, 200],    # Top-left area of page 0
  1 => [200, 300, 600, 500] # Bottom-right area of page 1
}
PdfExtractor.PdfPlumber.extract_text("path/to/document.pdf", pages, areas)
```

### Return Format

The function returns a map where keys are page numbers and values are the extracted text:

```elixir
%{
  0 => "Text from page 0...",
  1 => "Text from page 1...",
  2 => "Text from page 2..."
}
```
