Gnostice Document Studio .NET is the next-generation multi-format document-processing component suite for .NET developers. It has controls for viewing, printing, and converting PDF, DOCX, DOC, HTML, TXT, XLSX, XLS, ODS, XPS, BMP, JPEG, PNG, WMF, EMF, TIFF and MTIFF. Gnostice Document Studio comes with advanced multi-format document viewer controls for WinForms, WPF, and ASP.NET (WebForms and MVC). It also supports template-based DOCX/DOC mail-merge document creation. It can intelligently reconstruct page elements when converting PDF to DOCX. It can create PDF portfolios.

The ASP.NET Document Viewer supports viewing of PDF, DOCX, DOC, TXT, XLSX, XLS, ODS, BMP, JPEG, PNG, WMF, EMF, TIFF and MTIFF files. Unique features of the viewer include searching text in images using OCR, color inversion, and ability to work with all formats with a common GUI and API. PDF support includes interactive form-filling, annotations, thumbnails view, bookmarks view, and general viewing tools.

Gnostice Document Studio .NET is based on managed code and does not require external software or libraries such as Microsoft Word, Open XML SDK, Word Automation Services, Adobe PDF library or GhostScript. The OCR feature relies on an embedded unmanaged library. It has been tested completely for trouble-free operation under web, mobile and desktop deployments. The OCR feature can be disabled if it is not required.

Gnostice Document Studio .NET is also available as part of our "all-.NET-products-included" Gnostice DevSystem .NET Subscription.
