Конвертировать MHTML в изображение – облачные SDK и REST API MHTML в изображение Aspose.HTML Cloud v4.0 предоставляет простейший API для преобразования документов MHTML в форматы файлов изображений с высоким качеством, просто и быстро.
Формат MHTML приобрел популярность как формат электронных книг на основе XML и предназначен для адаптации представления контента к устройству чтения. Он реализован в виде архивного файла, состоящего из файлов XHTML, несущих контент, изображения и другие вспомогательные файлы. Иногда требуется получить изображение вместо документов MHTML, например сделать их переносимыми и легко распространяемыми на различных устройствах, создать галерею изображений из электронных книг и т. д.
В статье с помощью набора примеров кода объясняется, как преобразовать документ MHTML в форматы файлов изображений, такие как JPEG , PNG , GIF , TIFF или BMP с использованием Aspose.HTML Cloud SDK и вызовов REST API. SDK доступны на PHP, C++, Python, C#, Ruby, Java, Android, Swift и Node.js. Мы рассмотрим различные сценарии преобразования MHTML в изображение: из хранилища в хранилище, из локальной файловой системы в локальную файловую систему и т.д.
Примеры SDK для преобразования MHTML в изображения Широко распространенным вариантом использования функций Aspose.HTML Cloud SDK является обработка и преобразование файлов. Cloud SDK позволяет вам 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 изображение для различных случаев с использованием доступных пакетов SDK.
Пример 1. Конвертировать MHTML в JPG JPG – один из наиболее часто используемых форматов изображений. Его уникальность – контролируемая потеря качества при сжатии. Поэтому он широко используется для хранения и отправки графического контента (фотографии, сканированные копии, оцифрованные изображения) через Интернет. Давайте рассмотрим пример преобразования локального файла MHTML в формат JPG 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 JPG с применением языка C#. Локальный MHTML преобразуется в JPG и сохраняется по локальному пути. Вы можете скачать C# SDK из
репозитория GitHub .

Пример 2. Преобразование MHTML в PNG с явно заданными параметрами Формат изображений PNG широко используется для передачи изображений по сети, отображения фотографий и графики на веб-страницах и резервирования в облачных хранилищах. Преобразование MHTML в PNG может потребоваться, например, если вы хотите добавить веб-страницу в презентацию PowerPoint, вставить ее в блог для своих читателей или отправить по электронной почте. В примере ниже показано, как преобразовать MHTML в PNG с явно заданными параметрами и сохранить результат обратно в локальную файловую систему.

Пример 3. Преобразование MHTML в GIF в облачном хранилище 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 GIF с применением языка C#. Файл MHTML находится в облачном хранилище, преобразуется в GIF и сохраняется обратно в облачное хранилище. Вы можете скачать C# SDK из
репозитория GitHub .
