```elixir
def deps do
  [
    {:pdf_extractor, "~> 0.1.0"}
  ]
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..."
}
```
