Crea una diapositiva

Questa pagina descrive come aggiungere diapositive a una presentazione di Presentazioni Google esistente.

Presentazioni

Ogni singola pagina di una presentazione di Presentazioni è una diapositiva.

Per aggiungere una diapositiva alla presentazione, devi disporre dell'ID presentazione. Puoi trovare l'ID della presentazione aprendola in Presentazioni e volgendo lo sguardo al suo URL:

https://docs.google.com/presentation/d/presentationID/edit

Per aggiungere una diapositiva, utilizza il metodo batchUpdate() con l'ID presentazione e includi un CreateSlideRequest nel corpo della richiesta. L'ID della nuova diapositiva viene restituito nel corpo della risposta.

Esempio

L'esempio seguente mostra come aggiungere una diapositiva a una presentazione. Tutti i campi per CreateSlideRequest sono facoltativi. Questo esempio crea la diapositiva come seconda diapositiva, con il layout TITLE_AND_TWO_COLUMNS e un ID oggetto esplicito.

Apps Script

Dopo aver creato la slide, puoi aggiungere testo e forme.

Compilare i segnaposto

In genere i layout contengono forme segnaposto che vengono copiate nella diapositiva al momento della sua creazione. CreateSlideRequest ti consente di specificare gli ID oggetto utilizzati per questi segnaposto copiati tramite il campo placeholderIdMappings. In questo modo puoi modificare i segnaposto copiati nella stessa richiesta batchUpdate, il che migliora le prestazioni e consente di risparmiare quota. Per ulteriori informazioni, consulta l'esempio CreateSlideRequest.
