Gnostice Document Studio .NET 2019 R2

Gnostice Document Studio .NET is the next-generation .NET Core compliant 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 Xamarin, 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.

The Xamarin Document Viewer supports viewing of PDF, DOCX, DOC, TXT, XLSX, XLS, ODS, BMP, JPEG, GIF and PNG files. Unique features of the viewer include multiple page layouting and unlimited zoom.

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.

Version 2019 R2 - September 23, 2019

PDF Engine
A newly designed PDF engine is introduced that works across platforms. Since this engine is not yet at parity with the feature-set of the old PDF engine, it is enabled only for .NET Standard. So it is used by the new Xamarin document viewer control and also can be used in .NET Core / .NET Core 3 frameworks. Once its feature-set matches that of the old PDF engine, the old engine will be replaced with the new one for all platforms.
Features currently supported by the new PDF engine
Supported font types: Type 1, TrueType, CFF, CID
Supported image types: 8 BPC BMP and 8 BPC JPEG
Supported encryption algorithms: RC4 (40 bit & 128 bit) and AES (128 bit & 256 bit)
Stream decompression filter types:
Xamarin Document Viewer Control
A new Document Viewer control is introduced for Xamarin.Forms mobile apps (Android and iOS).

Document Engines
All existing document engines (except PDF) are now supported on .NET Standard compliant frameworks (.NET Core and Xamarin as well).
Updated file format prediction code to improve detection of supported files.
Digitization Engine
The digitization engine (OCR) is now supported on .NET Standard compliant frameworks as well.

Document Viewers
Both the WinForms and WPF viewer controls have been redesigned and rewritten from the ground-up.
The newly introduced Xamarin Document Viewer control, and the rewritten WinForms and WPF Document Viewer controls share bulk of their code via the newly introduced PageManager module. This new design allows for faster introduction of features into all viewers at the same time.
The WPF viewer now supports navigation via thumbnails as well as PDF bookmarks.
