Esempi per Amazon Textract con SDK per SAP ABAP

Gli esempi di codice seguenti mostrano come eseguire operazioni e implementare scenari comuni utilizzando AWS SDK per SAP ABAP con Amazon Textract.

Le azioni sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le operazioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati.

Scenari: esempi di codice che mostrano come eseguire un’attività specifica chiamando più funzioni all’interno dello stesso servizio o combinate con altri Servizi AWS.

Ogni esempio include un link al codice sorgente completo, in cui vengono fornite le istruzioni su come configurare ed eseguire il codice nel contesto.
