## Usage

### Document

A `MuPDF::Document` wraps a PDF file:

```ruby
document = MuPDF::Document.new('./file.pdf')
```

#### Info

The `info` command displays information about the document such as the number of pages:

```ruby
info = document.info
info.pages # e.g. 2
```

#### Pages

The `pages` command finds sizing information about the pages within a document:

```ruby
pages = document.pages
pages.count # e.g. 2
pages.each do |page|
  page.number # e.g. 1, 2, ...
  page.width # 612
  page.height # 792
end
```

#### Draw

The `draw` command is useful for converting a document between formats:

```ruby
document.pages.each do |page|
  document.draw(page: page.number, format: "png", path: "./file-#{page.number}.png")
end
```
