Cómo editar y aplicar estilos al texto

En esta página, se indica la forma de aplicar ajustes de edición y estilo a tu presentación usando la API de Presentaciones.

Información acerca del texto

El texto de tu presentación siempre se encuentra contenido dentro de una forma o la celda de una tabla. La API te permite modificar este texto de varias maneras:

  • Puedes insertar, borrar o reemplazar el texto de tu presentación.
  • Puedes agregar formato de párrafo para crear listas con viñetas.
  • Puedes cambiar el formato de caracteres, como negrita, cursiva, color, tamaño de fuente o hipervínculos.

Consulta la página de conceptos Text Structure and Styling para obtener una descripción general del funcionamiento de los ajustes de estilo de texto en la API de Presentaciones. Mira también el video anterior para ver un ejemplo completo (Python) en el que se combinan varios de los conceptos de formato de las secciones siguientes.

Inserción, borrado o reemplazo de texto

Existen dos formas de reemplazar el texto de una presentación usando la API de Presentaciones: realizar un procedimiento global de búsqueda y reemplazo, o bien borrar y agregar texto de manera explícita. En ambas alternativas se usa el método batchUpdate, aunque con diferentes tipos de solicitudes.

Búsqueda y reemplazo globales

Usa ReplaceAllTextRequest para realizar un procedimiento global de búsqueda y reemplazo en tu presentación.

En la sección Combinación de texto de la guía Combinar datos, se proporciona un ejemplo de cómo puedes usar este tipo de solicitud.

Reemplazo de texto dentro de una forma

La API de Presentaciones te permite modificar el contenido textual de una forma. Puedes quitar rangos de texto individuales e insertar texto en una ubicación específica.

Usa InsertTextRequest y DeleteTextRequest para realizar estas operaciones.

El reemplazo de una sección específica de texto implica una eliminación y, luego, una inserción. Puedes realizarlo siguiendo estos pasos:

  1. Identifica el elemento de página que contiene el texto.
  2. Identifica la posición de inicio y fin del texto que se reemplazará.
  3. Llama a batchUpdate con las siguientes dos solicitudes:
    1. DeleteTextRequest, que especifica el rango de texto que se borrará.
    2. InsertTextRequest, que especifica la misma posición de inicio y la cadena de texto que se insertará.

Para garantizar atomicidad al reemplazar texto de esta manera, asegúrate de incluir ambas solicitudes en la misma llamada al método batchUpdate. Esto se muestra en el siguiente ejemplo, en el cual se reemplaza todo el texto de una forma por texto nuevo:

Cómo cambiar el formato de los caracteres

El formato de caracteres determina la representación de caracteres de texto en tu presentación, incluidos el tipo de letra, el color y los hipervínculos.

En la página de conceptos Text Structure and Styling, se describe la forma en que la API de Presentaciones representa información de ajuste de estilos de texto.

Para cambiar el formato de caracteres del texto, usa batchUpdate con UpdateTextStyleRequest. Debes proporcionar el ID de la forma o la celda de tabla que contiene el texto, así como un rango que incluya la siguiente información:

  • El especificador FIXED_RANGE, junto con los índices de inicio y finalización que definen el rango de texto al cual deseas aplicar ajustes de estilo.
  • El especificador FROM_START_INDEX, junto con un índice de inicio que define el inicio del rango de texto al cual desees aplicar ajustes de estilo.
  • El especificador ALL, sin índices, para aplicar estilo a todo el texto de la forma de destino.

En el siguiente ejemplo, se realizan varias operaciones de ajuste de estilo en el texto que se encuentra contenido en una forma:

  • Establece la fuente de los caracteres del 0 al 4 en negrita y cursiva.
  • Establece el color de los caracteres 5 a 9 en blue, con fuente Times New Roman de tamaño 14 pt.
  • Se aplican hipervínculos a los caracteres 10 a 14 a www.example.com.

Una manera directa de hacer esto es crear una lista de solicitudes y, luego, usar una llamada a 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 {*}

Cómo cambiar el formato de un párrafo

El formato de párrafos determina la forma en que se representan los bloques de texto en tu presentación, incluidos la alineación, las sangrías y la ornamentación de listas.

En la página de conceptos Text Structure and Styling, se describe cómo la [[slides_api_short]] representa la información de los ajustes de estilo de los párrafos.

La API de Presentaciones admite la actualización de estilos de párrafos, la conversión de párrafos sin formato en listas con viñetas y la eliminación de viñetas de los párrafos.

Convierte párrafos en una lista

Una operación de formato de párrafos común consiste en convertirlos en una lista con viñetas. En el siguiente ejemplo, se convierten todos los párrafos de una forma en una lista con viñetas y se especifica un glifo de viñeta explícito que se usará.
