Параметры конвертации – Aspose.HTML Cloud SDK

Aspose.HTML Cloud представляет собой простейший API для преобразования HTML-страницы в форматы документов с фиксированным макетом, включая PDF, XPS, DOC и DOCX; в форматы MD и MHTML; а также в форматы растровых изображений, такие как JPEG, PNG, TIFF, BMP и GIF.

Семейство Aspose.HTML Cloud SDK предоставляет набор классов, которые представляют параметры преобразования. Параметры преобразования позволяют настроить процесс преобразования. Вы можете указать размер страницы файла, поля и т. д. В этой статье описывается набор классов, которые представляют параметры преобразования PDF, XPS и изображений.
