Questa pagina spiega come modificare e applicare stili al testo di una presentazione utilizzando l'API Presentazioni.
Informazioni sul testo
Il testo della presentazione è sempre contenuto in una forma o cella di tabella. L'API consente di modificare questo testo in diversi modi:
- Puoi inserire, eliminare o sostituire testo nella presentazione.
- Puoi aggiungere la formattazione del paragrafo per creare elenchi puntati.
- Puoi modificare la formattazione dei caratteri, ad esempio grassetto, corsivo, colore, dimensione o link ipertestuali.
Consulta la pagina dei concetti Struttura del testo e stili per una panoramica generale su come funzionano gli stili di testo nell'API Presentazioni. Guarda anche il video qui sopra per vedere un esempio completo (Python) che combina molti dei concetti di formattazione riportati nelle sezioni seguenti.
Inserimento, eliminazione o sostituzione di testo
Esistono due modi per sostituire il testo in una presentazione utilizzando l'API Presentazioni: eseguendo una ricerca e sostituisci a livello globale oppure eliminando e aggiungendo testo. In entrambi i modi, viene utilizzato il metodo batchUpdate ma con tipi di richieste diversi.
Ricerca e sostituzione globali
Utilizza ReplaceAllTextRequest eseguire una ricerca globale e sostituirla durante tutta la presentazione.
La sezione Unione del testo della sezione La guida ai dati fornisce un esempio di come puoi utilizzare questo tipo di richiesta.
Sostituzione di testo all'interno di una forma
L'API Presentazioni ti consente di modificare il contenuto testuale di una forma. Puoi rimuovere singoli intervalli di testo ed è possibile inserire il testo in una posizione specifica.
Utilizza InsertTextRequest e DeleteTextRequest per eseguire queste operazioni.
La sostituzione di una regione specifica di testo consiste in un'eliminazione, quindi per l'inserimento, che puoi eseguire seguendo questa procedura:
- Identifica l'elemento della pagina che contiene il testo.
- Identifica la posizione iniziale e finale del testo da sostituire.
- Chiama
batchUpdate
con le due richieste seguenti:- DeleteTextRequest, che specifica l'intervallo di testo da eliminare.
- InsertTextRequest, che specifica la stessa posizione iniziale e la stringa di testo inserito.
Per garantire l'atomicità quando sostituisci il testo in questo modo, assicurati di includere entrambi nella stessa chiamata batchUpdate. Questo è mostrato nell'esempio seguente, che sostituisce tutto il testo di una forma con un nuovo testo:
Apps Script

Modifica della formattazione dei caratteri
La formattazione dei caratteri determina la visualizzazione dei caratteri di testo nel presentazione, inclusi carattere tipografico, colore e link ipertestuali.
La pagina dei concetti Struttura del testo e stili descrive il modo in cui l'API Presentazioni rappresenta le informazioni sugli stili del testo.
Per modificare la formattazione dei caratteri del testo, usa batchUpdate
con
UpdateTextStyleRequest.
Devi fornire l'ID della forma o della cella della tabella che contiene il testo,
nonché un intervallo
che include le seguenti informazioni:
- L'indicatore
FIXED_RANGE
, insieme agli indici di inizio e di fine definisci l'intervallo di testo a cui applicare uno stile. - L'indicatore
FROM_START_INDEX
, insieme a un indice iniziale che definisce l'inizio dell'intervallo di testo a cui applicare uno stile. - L'indicatore
ALL
, senza indici, per definire tutto il testo nel target forma.
Nell'esempio seguente vengono eseguite diverse operazioni di stile del testo contenuto in una forma:
- Imposta il carattere dei caratteri da 0 a 4 in grassetto corsivo.
- Imposta il colore dei caratteri da 5-9 a
blue
carattere Times New Roman da 14 pt. - Link ipertestuali da 10 a 14 a
www.example.com
.
Un modo semplice per farlo è creare un elenco di richieste e quindi utilizzando un metodo batchUpdate chiama:
Apps Script

Modifica della formattazione del paragrafo
La formattazione del paragrafo determina il rendering dei blocchi di testo nelle presentazione, tra cui allineamento, rientro e ornamentazione dell'elenco.
La pagina dei concetti Struttura del testo e stili descrive il modo in cui [[slides_api_short]] rappresenta le informazioni sugli stili dei paragrafi.
L'API Presentazioni supporta l'aggiornamento degli stili dei paragrafi, la conversione di paragrafi semplici agli elenchi puntati e la rimozione di punti elenco dai paragrafi.
Conversione dei paragrafi in un elenco
Un'operazione comune di formattazione dei paragrafi consiste nel convertire i paragrafi in un elenco puntato. L'esempio seguente converte tutti i paragrafi di una forma a un elenco puntato e specifica un glifo punto elenco esplicito da utilizzare.
