Gnostice XtremeDocumentStudio .NET is the next-generation multi-format document-processing component suite for .NET developers. Currently, it supports viewing, printing, and converting PDF, DOCX, DOC, BMP, JPEG, PNG, WMF, EMF, TIFF and MTIFF. More formats will be introduced in future. XtremeDocumentStudio includes multi-format document viewer controls for WinForms, WebForms, MVC, WPF, and HTML5. It can also convert document from one format to another, such as DOCX-to-PDF or PDF to images without requiring any other external software or libraries. It can also intelligently reconstruct page elements when converting PDF to DOCX. Some features such as programmatic document-creation, document-editing, and mail-merge have been introduced as a preview or beta.
XtremeDocumentStudio .NET is 100% managed code. It can natively process supported formats without requiring external software such as Microsoft Word, Open XML SDK, Word Automation Services, Adobe PDF library or GhostScript.
