Convierta MHTML en imagen – Cloud SDK y API REST MHTML a imagen Aspose.HTML Cloud v4.0 proporciona la API más sencilla para convertir documentos MHTML a formatos de archivos de imagen con alta calidad, fácil y rápido.
El formato MHTML 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. A veces, es necesario obtener una imagen en lugar de documentos MHTML, como hacerlos portátiles y compartirlos fácilmente en varios dispositivos, crear una galería de imágenes a partir de libros electrónicos, etc.
El artículo explica en un conjunto de ejemplos de código cómo convertir un documento MHTML a formatos de archivo de imagen como JPEG , PNG , GIF , TIFF o BMP usando los SDK de nube Aspose.HTML y llamadas API REST. Los SDK están disponibles en PHP, C++, Python, C#, Ruby, Java, Android, Swift y Node.js. Consideraremos varios escenarios de conversión de MHTML a imagen: de almacenamiento en almacenamiento, de un sistema de archivos local al sistema de archivos local, etc.
Ejemplos de SDK de conversión de MHTML a imagen Un caso de uso generalizado de las funciones de Aspose.HTML Cloud SDK es el procesamiento y la conversión de archivos. Cloud SDK le permite recuperar un documento MHTML 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 su disco local. Los siguientes ejemplos de código demuestran cómo convertir MHTML a imagen para diferentes casos utilizando los SDK disponibles.
Ejemplo 1. Convertir MHTML a JPG JPG es uno de los formatos de imagen más utilizados. Su singularidad es la pérdida controlada de calidad durante la compresión. Por tanto, es muy utilizado para almacenar y enviar contenido gráfico (fotos, copias escaneadas, imágenes digitalizadas) a través de Internet. Veamos un ejemplo de cómo convertir un archivo MHTML local a formato JPG y guardar el resultado en un sistema de archivos local. La conversión se produce con las opciones de conversión predeterminadas.
C# El siguiente ejemplo demuestra la forma más sencilla de convertir MHTML a JPG usando C#. MHTML local convertido a JPG y guardado en la ruta local. Puede descargar el SDK de C# desde el
repositorio de GitHub .

Ejemplo 2. Convertir MHTML a PNG con opciones especificadas explícitamente El formato de imagen PNG se utiliza ampliamente para transmitir imágenes a través de la red, mostrar fotografías y gráficos en páginas web y guardarlas en almacenamientos en la nube. Es posible que sea necesaria la conversión de MHTML a PNG, por ejemplo, si desea agregar una página web en una presentación de PowerPoint, insertarla en un blog para sus lectores o enviarla por correo electrónico. El siguiente ejemplo muestra cómo convertir MHTML a PNG con opciones especificadas explícitamente y guardar el resultado en el sistema de archivos local.
C# El siguiente ejemplo de SDK demuestra cómo convertir MHTML a PNG usando C#. MHTML se toma del sistema de archivos local, se convierte a PNG y se guarda en la unidad local. Puede descargar el SDK de C# desde el
