Instance Attribute Details

#language_hints ⇒ `Array<String>`

Returns List of languages to use for TEXT_DETECTION. In most cases, an empty value yields the best results since it enables automatic language detection. For languages based on the Latin alphabet, setting +language_hints+ is not needed. In rare cases, when the language of the text in the image is known, setting a hint will help get better results (although it will be a significant hindrance if the hint is wrong). Text detection returns an error if one or more of the specified languages is not one of the languages[https://cloud.google.com/translate/v2/translate-reference#supported_languages].
