ドキュメント内のテキストを検出するには

次の detect-document-text の例は、ドキュメント内のテキストを検出する方法を示しています。

Linux/macOS:

aws textract detect-document-text \ --document '{"S3Object":{"Bucket":"bucket","Name":"document"}}'

Windows :

aws textract detect-document-text \ --document "{\"S3Object\":{\"Bucket\":\"bucket\",\"Name\":\"document\"}}" \ --region region-name
