<commit_before># file_data

Ruby library that reads Exif tag data from Jpeg files. More file data formats may be supported in the future.

Examples for getting Exif tags:

```ruby
#All Exif tags from a file
exif = Exif.new
hash = exif.read_tags("path_to_file")

#All Exif tags from a binary stream
io = StringIO.open("...")
exif = Exif.new
hash = exif.read_tags(io)

#Only specific tag id numbers (see exif_tags.rb or the Exif spec)
image_width = 256
image_length = 257
exif = Exif.new
hash = exif.read_tags("path_to_file", image_width, image_length)
```

Return Values:
Tag type TYPE_UNDEFINED: Array of bytes and boolean which is true if the bytes are little endian
Tag type that is not recognized: nil
Otherwise: The value as the most appropriate type<commit_msg>Updated spacing in readme<commit_after># file_data
