Über GroupDocs.Viewer for .NET

Document Viewer-API für die Darstellung Dokumentenformaten in PDF, HTML oder in Bildern.

GroupDocs.Viewer for .NET helps you create applications that can render and display documents and images in 90+ file ‎formats without installing any external software. The file viewer library rasterizes documents and then converts them to SVG/HTML/CSS for viewing business documents, images, ‎text files, diagrams, graphics, email attachments and PDF files. You can display ‎a whole document, a partial document, a specific page/cell range, an individual document layer, with or ‎without annotations and comments for supported formats.‎ GroupDocs.Viewer for .NET caches the output to the local disk by default. Any type of external cache storage is also supported by implementing appropriate interfaces – Amazon S3, Dropbox, Google Drive, Windows Azure, Redis or any other.
