Unisci dati in una presentazione

Un'applicazione utile dell'API Presentazioni Google è l'unione di informazioni o più origini dati in una presentazione basata su modelli.

Questa pagina illustra come acquisire dati da un'origine esterna e inserirlo in una presentazione modello esistente. Il concetto è in modo simile a quello dell'unione dinamica con un elaboratore di testi e un foglio di lavoro.

Questo approccio risulta utile per diversi motivi:

  • I designer possono perfezionare facilmente il design di una presentazione utilizzando nell'editor di Presentazioni Google. Questo è molto più facile rispetto all'ottimizzazione dei parametri in dell'app per impostare il rendering della slide.

  • La separazione dei contenuti dalla presentazione è un'attività molto nota che offre molti vantaggi.

Diagramma concettuale di un'unione.

Una ricetta base

Ecco un esempio di come puoi utilizzare l'API Presentazioni per unire i dati in una presentazione:

  1. Crea la presentazione nel modo che preferisci utilizzando segnaposto per aiutarti con la progettazione.

  2. Per ogni elemento di contenuto che dovrai inserire, sostituisci il segnaposto con un tag. I tag sono caselle di testo o forme con una stringa univoca. Assicurati di utilizzare stringhe che difficilmente si presentano normalmente. Ad esempio: {{account-holder-name}} potrebbe essere un buon tag.

  3. Nel tuo codice, utilizza l'API Google Drive per creare una copia del una presentazione.

  4. Nel codice, utilizza il comando gcloud batchUpdate , con un insieme di replaceAllText per eseguire tutte le sostituzioni del testo nel corso della presentazione. Utilizza replaceAllShapesWithImage per eseguire la sostituzione delle immagini in tutta la presentazione.

Dopo aver creato una presentazione contenente tag, assicurati di creare una copia e utilizzare l'API Presentazioni per manipolare la copia. Non utilizzare l'API Presentazioni per manipolare il "modello" principale copia!

Le seguenti sezioni includono snippet di codice che illustrano alcune di queste e il processo di sviluppo. Puoi anche guardare il video qui sopra per vedere un esempio completo (Python) che combinano molti dei concetti delle singole sezioni di seguito.

Unisci testo

Puoi utilizzare una replaceAllText di sostituire tutte le istanze di una determinata stringa di testo in un una presentazione con nuovo testo. Per le unioni, questa procedura è più semplice di trovare e sostituire singolarmente ciascuna istanza di testo. Uno dei motivi per cui l'approccio più sofisticato è che gli ID degli elementi di pagina sono difficili da prevedere, soprattutto quando i collaboratori permettono di perfezionare e gestire il modello. una presentazione.

Esempio

In questo esempio viene usata l'API Drive per copiare un modello di presentazione, rendendo una nuova istanza della presentazione. Quindi utilizza l'API Fogli Google per leggere i dati da un foglio di lavoro di Fogli e infine usa l'API Presentazioni per aggiornare nuova presentazione.

L'esempio prende i dati da 3 celle in una riga di un intervallo denominato in un foglio di lavoro. Sostituisce poi questi dati nella presentazione ovunque la stringa {{customer-name}}, {{case-description}}, oppure Si verificano {{total-portfolio}}.

Unisci immagini

Puoi anche unire le immagini nella presentazione utilizzando un replaceAllShapesWithImage richiesta. Questa richiesta sostituisce tutte le istanze di forme contenenti stringa di testo fornita con l'immagine fornita. La richiesta viene inviata automaticamente posiziona e ridimensiona l'immagine per adattarla ai limiti della forma del tag, conservando le proporzioni dell'immagine.

Esempio

In questo esempio viene usata l'API Google Drive per copiare un modello di presentazione, rendendo una nuova istanza della presentazione. Quindi utilizza l'API Presentazioni per trovare qualsiasi forma con il testo {{company-logo}} e sostituirlo con l'immagine del logo dell'azienda. La richiesta sostituisce anche qualsiasi forma con il testo {{customer-graphic}} con un'immagine diversa.

Sostituisci caselle di testo o istanze di immagini specifiche

La replaceAllText e replaceAllShapesWithImage richieste sono utili per sostituire i tag in una presentazione, ma a volte basta sostituire gli elementi in base a un altro criterio, come come trovarsi in una slide specifica.

In questi casi, devi recuperare gli ID delle forme di tag che sostituire. Per le sostituzioni del testo, devi eliminare il testo in quelle forme e poi inserisci il nuovo testo (vedi l'esempio Modificare il testo in una forma specificata).

La sostituzione delle immagini è più complessa. Per unire un'immagine, devi:

  1. Recuperare l'ID della forma del tag.
  2. Copia la dimensione e trasforma le informazioni dal tag.
  3. Aggiungi l'immagine alla pagina, utilizzando le dimensioni e le informazioni trasformate.
  4. Elimina la forma del tag.

È possibile mantenere le proporzioni dell'immagine e ridimensionarla alla dimensione desiderata richiedono alcune cure, come descritto nella sezione seguente. Vedi anche questo esempio: Sostituisci un tag di forma con un'immagine.

Mantieni proporzioni

Quando crei immagini utilizzando l'API Presentazioni, l'aspetto si basa solo sul dimensioni dell'immagine, non su quelle e trasformano i dati. I dati sulle dimensioni forniti in createImage la richiesta è considerata delle dimensioni desiderate dell'immagine. L'API è adatta le proporzioni dell'immagine alle dimensioni desiderate, quindi applica la trasformazione fornita.

Quando sostituisci un tag con un'immagine, ne mantieni l'aspetto di immagine impostando le dimensioni e il ridimensionamento dell'immagine come segue:

  • width: impostato sul prodotto di width e scaleX del tag
  • height: impostato sul prodotto dei valori height e scaleY del tag
  • scale_x: impostato su 1
  • scale_y: impostato su 1

In questo modo l'API Presentazioni si adatta all'immagine in base al le dimensioni visive del tag, anziché le dimensioni non in scala (vedi Sostituisci un tag di forma con un'immagine). L'impostazione dei parametri di scalabilità su 1 impedisce che l'immagine venga ridimensionata due volte.

Questa disposizione garantisce che le proporzioni dell'immagine vengano mantenute e impedisce l'immagine in modo che non superi le dimensioni della forma del tag. L'immagine contiene nello stesso punto centrale della forma del tag.

Gestisci modelli

Per le presentazioni modello che l'applicazione definisce e possiede, crea utilizzando un account dedicato che rappresenta l'applicazione. Account di servizio sono una buona scelta ed evita complicazioni con i criteri di Google Workspace che limitano condivisione.

Quando crei istanze di presentazioni a partire da modelli, usa sempre le credenziali dell'utente finale. Ciò offre agli utenti il controllo completo alla presentazione risultante e impedisce i problemi di scalabilità legati limiti di Google Drive.

Per creare un modello utilizzando un account di servizio, segui questi passaggi con le credenziali dell'applicazione:

  1. Crea una presentazione utilizzando presentations.create nell'API Presentazioni.
  2. Aggiorna le autorizzazioni per consentire ai destinatari della presentazione di leggerla utilizzando permissions.create nell'API Drive.
  3. Aggiorna le autorizzazioni per consentire agli autori dei modelli di scrivere nei file utilizzando permissions.create nell'API Drive.
  4. Modifica il modello come richiesto.

Per creare un'istanza della presentazione, segui questi passaggi con le credenziali utente:

  1. Crea una copia del modello utilizzando files.copy nell'API Drive.
  2. Sostituisci i valori utilizzando presentation.batchUpdate nell'API Presentazioni.
