Конвертировать MHTML в PDF – облачные SDK и REST API MHTML в PDF PDF – это статический документ, который может содержать текст, изображения, поля формы, мультимедиа, цифровые подписи, гиперссылки и т. д. Преобразование MHTML в PDF сохраняет макет и форматирование, обеспечивая при этом автономный доступ, совместное использование и печать веб-контента. Файлы PDF сохраняют визуальное представление исходного содержимого MHTML, что делает их пригодными для просмотра на различных устройствах и платформах без подключения к Интернету. Широкие возможности совместимости и безопасности PDF также расширяют возможности совместного использования и распространения документов, позволяя пользователям контролировать доступ и защищать конфиденциальную информацию.
Aspose.HTML Cloud v4.0 предоставляет простейший API для преобразования документов MHTML в формат PDF с высоким качеством, просто и быстро.
В статье в наборе примеров кода объясняется, как преобразовать документ MHTML в PDF с помощью клиентских SDK Aspose.HTML Cloud и REST API. SDK доступны на PHP, C++, Python, C#, Ruby, Java, Android, Swift и Node.js. Мы рассмотрим различные сценарии преобразования MHTML в PDF:
Преобразование локального файла MHTML в PDF и сохранение результата в локальной файловой системе. В этом сценарии мы рассмотрим как преобразования с параметрами преобразования по умолчанию, так и с явно заданными параметрами. Преобразование MHTML в PDF в облачном хранилище с параметрами преобразования по умолчанию. Примеры преобразования MHTML в PDF Широко распространенным вариантом использования функций Aspose.HTML Cloud является обработка и преобразование файлов. Cloud SDK позволяет получить документ MHTML из места хранения по его имени или из локального файла на вашем диске, преобразовать его в указанный формат и сохранить в хранилище или на локальном диске. Следующие примеры кода демонстрируют, как преобразовать MHTML в PDF для различных случаев с использованием доступных SDK и REST API.
Пример 1. Конвертировать MHTML в PDF с параметрами сохранения по умолчанию Давайте рассмотрим пример преобразования локального файла MHTML в PDF и сохранения результата в локальную файловую систему. Преобразование происходит с параметрами преобразования по умолчанию.
C# В следующем примере демонстрируется самый простой способ преобразования MHTML в PDF с применением языка C#. Вы можете скачать C# SDK из

Пример 3. Конвертировать MHTML в PDF внутри облачного хранилища Aspose.HTML Cloud позволяет вам получить файл MHTML из вашего облачного хранилища и сохранить результат преобразования обратно в облачное хранилище. Преобразование происходит с параметрами преобразования по умолчанию.
C# В следующем примере показано, как преобразовать MHTML в PDF с применением языка C#. Файл MHTML находится в облачном хранилище, конвертируется в PDF и сохраняется обратно в облачное хранилище. Вы можете скачать C# SDK из
репозитория GitHub .
