Convierta EPUB a XPS usando Cloud SDK – Aspose.HTML

Aspose.HTML Cloud ofrece una API sencilla para convertir de forma rápida y eficiente documentos EPUB al formato XPS. El formato EPUB ha ganado popularidad como formato de libro electrónico basado en XML y está diseñado para adaptar la presentación del contenido al dispositivo lector. Se implementa como un archivo que consta de archivos XHTML que contienen el contenido, imágenes y otros archivos de soporte.

El artículo explica en un conjunto de ejemplos de código cómo convertir un documento EPUB a XPS utilizando los SDK del cliente Aspose.HTML Cloud y las llamadas a la API REST. Consideraremos varios escenarios de conversión de EPUB a XPS. Los SDK están disponibles en PHP, C++, Ruby, Python, C#, Java, Android, Swift y más.

Ejemplos de SDK de conversión de EPUB a XPS

Un caso de uso generalizado de las funciones de Aspose.HTML Cloud SDK es el procesamiento y la conversión de archivos. Las API de la nube le permiten recuperar un documento EPUB de una ubicación de almacenamiento por su nombre o de un archivo local en su disco, convertirlo a un formato específico y guardarlo en el almacenamiento o en el disco local. Los siguientes ejemplos de código demuestran cómo convertir EPUB a XPS para diferentes casos utilizando los SDK y cURL disponibles.

Ejemplo 1. Convertir EPUB a XPS

El siguiente ejemplo demuestra la forma más sencilla de convertir EPUB a XPS usando C#. EPUB local convertido a XPS y guardado en la ruta local. Puede descargar el SDK de C# desde el repositorio de GitHub.

CURL

The following example demonstrates how to convert EPUB to XPS using REST API. Local EPUB converted to XPS and saved to the local path. Follow a few required steps:

Upload local file to storage using Storage API.
Call REST API to execute conversion (in the example below).
Download conversion result back from storage using Storage API.

1curl -X POST -v \
2	"https://api.aspose.cloud/v4.0/html/conversion/epub-xps" \
3    -d "{'InputPath': '/testpage.epub', 'OutputFile': 'test.xps'}" \
4    -H "Content-Type: application/json" \
5    -H "Authorization:Bearer <JWT_token>"

La conversión de EPUB a XPS se produce con las opciones de conversión predeterminadas: el ancho y el alto del documento XPS resultante corresponden a A4, y todos los márgenes tienen valor cero.

CURL

The following example demonstrates how to convert EPUB to XPS using REST API. Local EPUB converted to XPS and saved to the local file system. Follow a few required steps:

Upload a local file to storage using Storage API.
Call REST API to execute conversion (in the example below).
Download conversion result back from storage using Storage API.

1curl -X POST -v \
2	"https://api.aspose.cloud/v4.0/html/conversion/epub-xps" \
3    -d "{'InputPath': '/testpage.epub', 'OutputFile': 'test.xps', 'Options': {'Width':1000, 'Height': 800, 'LeftMargin': 10, 'RightMargin': 10, 'TopMargin': 10, 'BottomMargin': 10}}" \
