Elixir wrapper for [Tesseract OCR](https://github.com/tesseract-ocr), an open

source text recognition (OCR) Engine.

## Requirements

- Elixir 1.6+ / Erlang OTP 19+

- [Tesseract OCR binary](https://github.com/tesseract-ocr/tesseract/wiki)

## Installation

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

```elixir

def deps do

  [

    {:tesseract_ocr, "~> 0.1.5"}

  ]

end

```

## Usage

Reading an image file.

```elixir

iex> TesseractOcr.read("test/resources/world.png")

"world"

```

With additional options.

```elixir

iex> TesseractOcr.read("test/resources/world.png", %{lang: "por", psm: 7, oem: 1})

"world"

```

Get words positions.

```elixir

iex> TesseractOcr.Words.read("test/resources/world.png")

[%{confidence: 95, word: "world", x_end: 185, x_start: 2, y_end: 56, y_start: 2}]

```

Convert image into PDF with text.

```elixir

iex> TesseractOcr.PDF.read("test/resources/world.png", "/tmp/test")

"/tmp/test.pdf"

```

Convert image into TSV with text.

```elixir

iex> TesseractOcr.TSV.read("test/resources/world.png", "/tmp/test")

"/tmp/test.tsv"

```
