Exemples d'Amazon Textract utilisant pour SDK SAP ABAP

Les exemples de code suivants vous montrent comment effectuer des actions et implémenter des scénarios courants en utilisant le AWS SDK for SAP ABAP avec Amazon Textract.

Les actions sont des extraits de code de programmes plus larges et doivent être exécutées dans leur contexte. Les actions vous indiquent comment appeler des fonctions de service individuelles, mais vous pouvez les visualiser dans leur contexte dans les scénarios correspondants.

Les scénarios sont des exemples de code qui vous montrent comment accomplir des tâches spécifiques en appelant plusieurs fonctions au sein d'un service ou en les combinant à d'autres Services AWS.

Chaque exemple inclut un lien vers le code source complet, où vous trouverez des instructions sur la façon de configurer et d'exécuter le code en contexte.
