### Render QR Code to Console

Source: https://hexdocs.pm/qrcode_ex/0.1.1

Generate an ASCII representation of the QR code directly in the console.

```elixir
qr_code_content
|> QRCodeEx.encode()
|> QRCodeEx.render()
```

--------------------------------

### Save PNG QR Code to File

Source: https://hexdocs.pm/qrcode_ex/0.1.1

After generating PNG binary data, use `File.write` to save it to a specified path.

```elixir
qr_code_png =
  qr_code_content
  |> QRCodeEx.encode()
  |> QRCodeEx.png()

File.write("path/where/you/want/to/save.png", qr_code_png, [:binary])
```

--------------------------------

### Add QRCodeEx Dependency

Source: https://hexdocs.pm/qrcode_ex/0.1.1

Add the QRCodeEx library to your project's dependencies in `mix.exs`.

```elixir
def deps do
  [
    {:qrcode_ex, "~> 0.1.0"}
  ]
end
```

### Generate QR Code to PNG

Source: https://hexdocs.pm/qrcode_ex/0.1.1

Encode content and generate a QR code in PNG format. The output is binary data that needs to be written to a file.

```elixir
qr_code_content = "your_qr_code_content"

# To PNG
qr_code_content
|> QRCodeEx.encode()
|> QRCodeEx.png()
```

### Generate QR Code to SVG

Source: https://hexdocs.pm/qrcode_ex/0.1.1

Encode content and generate a QR code in SVG format. No file writing is needed as SVG is directly output.

```elixir
qr_code_content = "your_qr_code_content"

# To SVG
qr_code_content
|> QRCodeEx.encode()
|> QRCodeEx.svg()
```

--------------------------------

### Customize SVG QR Code

Source: https://hexdocs.pm/qrcode_ex/0.1.1

Pass options to `QRCodeEx.svg()` to customize color, shape, size, and background.

```elixir
qr_code_content
|> QRCodeEx.encode()
|> QRCodeEx.svg(color: "#03B6AD", shape: "circle", width: 300, background_color: "#FFF")
```
