getLanguageHints(int index)
public String getLanguageHints(int index)
List of languages to use for OCR. 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). Document processing returns an
error if one or more of the specified languages is not one of the
supported languages.
repeated string language_hints = 1;
| Parameter |
|---|
| Name | Description |
index | int
The index of the element to return.
|
| Returns |
|---|
| Type | Description |
String | The languageHints at the given index.

getLanguageHintsBytes(int index)
public ByteString getLanguageHintsBytes(int index)
List of languages to use for OCR. In most cases, an empty value

needed. In rare cases, when the language of the text in the image is known,
