Aspose.HTML Cloud SDK for C++ enables developers to build powerful cloud‑based HTML renderer and converter applications. It offers extensive functionality for converting HTML files into multiple fixed‑layout document formats such as PDF, XPS, and DOCX; raster image formats including JPEG, PNG, TIFF, BMP, and GIF; as well as Markdown and MHTML formats. Additionally, it allows vectorization of images by converting JPEG, PNG, TIFF, BMP, and GIF to SVG. The SDK provides advanced capabilities such as fetching full HTML pages with linked resources as ZIP files, extracting all images from a webpage, performing XPath or CSS‑based HTML fragment queries, and populating HTML templates with data from local files or request bodies. It supports conversion operations directly from cloud storage or stream input, as well as loading HTML from a webpage URL. The SDK requires no installation—developers only need an Aspose Cloud account, App SID, and App Key to start using it across platforms.
