Modifica e applicazione di stili al testo

Questa pagina spiega come modificare e stile il testo della 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 del carattere o link ipertestuali.

Consulta la pagina dei concetti Struttura del testo e stili per una panoramica generale di come funzionano gli stili del 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 in modo esplicito il testo. Entrambi i modi utilizzano il metodo batchUpdate, ma con tipi di richieste diversi.

Ricerca e sostituzione globali

Utilizza ReplaceAllTextRequest per eseguire una ricerca e sostituire a livello globale in tutta la presentazione.

La sezione Unione del testo della guida sull'unione dei 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 e inserire testo in una posizione specifica.

Utilizza InsertTextRequest e DeleteTextRequest per eseguire queste operazioni.

La sostituzione di una regione specifica di testo prevede un'eliminazione e quindi un inserimento, che puoi eseguire seguendo questa procedura:

  1. Identifica l'elemento della pagina che contiene il testo.
  2. Identifica la posizione iniziale e finale del testo da sostituire.
  3. Chiama batchUpdate con le due richieste seguenti:
    1. DeleteTextRequest, specificando l'intervallo di testo da eliminare.
    2. InsertTextRequest, specificando la stessa posizione iniziale e la stringa di testo da inserire.

Per garantire l'atomicità quando sostituisci il testo in questo modo, assicurati di includere entrambe le richieste nella stessa chiamata batchUpdate. Ciò è mostrato nell'esempio seguente, che sostituisce tutto il testo di una forma con nuovo testo:

Modifica della formattazione dei caratteri

La formattazione dei caratteri determina il rendering dei caratteri di testo nella presentazione, tra cui carattere tipografico, colore e link ipertestuali.

La pagina dei concetti Struttura del testo e stili descrive in che modo l'API Presentazioni rappresenta le informazioni sugli stili del testo.

Per modificare la formattazione dei caratteri del testo, utilizza batchUpdate con UpdateTextStyleRequest. Devi fornire l'ID della forma o della cella della tabella che contiene il testo, nonché un intervallo che includa le seguenti informazioni:

  • L'indicatore FIXED_RANGE, insieme agli indici di inizio e fine che definiscono l'intervallo di testo da applicare allo stile.
  • L'indicatore FROM_START_INDEX, insieme a un indice iniziale che definisce l'inizio dell'intervallo di testo da applicare allo stile.
  • L'indicatore ALL, senza indici, per definire tutto il testo nella forma di destinazione.

Nell'esempio seguente vengono eseguite diverse operazioni di stile del testo sul 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 utilizzare una chiamata batchUpdate:

Apps Script

slides/api/Snippets.gs
/**
 * Update the text style so that the first 5 characters are bolded
 * and italicized, the next 5 are displayed in blue 14 pt Times
 * New Roman font, and the next 5 are hyperlinked.
 * @param {string} presentationId
 * @param {string} shapeId
 * @returns {*}

Modifica della formattazione del paragrafo

La formattazione del paragrafo determina il modo in cui vengono visualizzati i blocchi di testo nella presentazione, tra cui allineamento, rientro e ornamento 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 in 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 in un elenco puntato e specifica un glifo punto elenco esplicito da utilizzare.
