Easy Integrate GroupDocs.Annotation for .NET Library into Your ASP.NET MVC5 App

GroupDocs.Annotation for .NET Library logoGroupDocs.Annotation for .NET library is a web-based framework which provides features for annotating different types of documents in a web-browser without having to install plugins or middleware on the client. With GroupDocs.Annotation, end users can view and annotate PDF, Microsoft Word, Excel, Outlook, PowerPoint, OpenOffice, AutoCAD and other types of documents and image files. The library comes with a set of commenting and markup tools, including: rectangles, polylines, watermarks, point and area notes, text markup and strikeouts.

In this article I'd like to help you discover the GroupDocs.Annotation for .NET library's basic functionality: how it works, where annotations are stored, how to manage users, etc. I'm also going to show you how to use the library in an ASP.NET MVC application. The sample project described in the article is based on MVC5, but most of the code can be used with any other versions of the MVC framework.

Stripping GroupDocs.Viewer for .NET Functionality Down to a Lightweight Document Embedding Tool

GroupDocs.Viewer for .NET Library logoGroupDocs.Viewer for .NET is a web-oriented framework which provides ample possibilities to view a wide variety of documents in a web-browser, including PDF, Word, Excel, PowerPoint, AutoCAD and many more. However, quite often there are situations when you are looking for a simple and quick solution and don't need all the functionality that comes with a library. In case of GroupDocs.Viewer, for example, you may not want to use iframes on your pages, or add a lot of additional JavaScript and CSS files, which are used by GroupDocs.Viewer. You may also want to limit the number of asynchronous requests/responses through which the viewer works. Or, strip down the UI and just display documents without options to zoom, print, download, etc. In this article I'm going to show you how to implement such scenario using the GroupDocs.Viewer for .NET library.

Using a Network Storage with the GroupDocs.Annotation for .NET Library

Greetings everyone!
GroupDocs.Annotation for .NET Library logo

Not all of you might know that the latest version of the GroupDocs.Annotation for .NET library can read and save annotated documents not only from local storage or web links, but also from network storage. In other words, you can now locate documents on any network machine.

This feature can be useful for businesses who have several machines networked to one main storage, or for customers who use one machine as a server and another one as a file storage. In this article I'd like to show you how to use network storage with the GroupDocs.Annotation for .NET library and how to configure your servers.

Loading Documents from Streams with the GroupDocs.Viewer for .NET Library

Greetings!

As you may noticed, in most of the GroupDocs.Viewer for .NET sample projects, target documents are presented in the form of files. They are placed in the "testfiles" folder usually, which is specified in the Global.asax. So you might think that GroupDocs.Viewer can work with files only.

But this is not true - GroupDocs.Viewer can also load documents from byte streams (System.IO.Stream). Moreover, there are no limitations on the type of stream: whether it's a FileStream, a MemoryStream or a NetworkStream - GroupDocs.Viewer can work with all of them. In this new article I'd like to show you how to load documents from streams in a simple ASP.NET WebForms project.

GroupDocs.Viewer for .NET Module Is Now Available for DNN Users

Good news for DNN users - we've recently released a module which allows you to integrate GroupDocs.Viewer for .NET into DNN CMS. Using the module you can seamlessly embed our HTML5 document viewer into your DNN site and display over 45 types of documents and images on any web page.

Different from our cloud-based module, this version is developed based on the GroupDocs.Viewer for .NET library, which means you can now store and process documents on your own servers. Existing users of the GroupDocs.Viewer for .NET library can use the module for free. In case you don't have a license for the library yet, please contact our sales for a free 30-day evaluation copy.

For more information on the module and installation instructions, please visit this page on the official DNN store.

Manage User Permissions by Replacing HTTP Handlers in GroupDocs.Viewer for .NET Library

Greetings everyone!
As you may know, GroupDocs.Viewer allows you to open and browse different types of documents (PDF, Word, Excel, etc.) in a browser, without any third-party plugins or programs. The viewer simply converts documents to a set of images, HTML, CSS and SVG and combines them to render the documents in HTML pages. GroupDocs.Viewer has several implementations designed for different platforms and forms of distribution. One of them is a .NET library. It is in fact a single DLL file which is easy to use in ASP.NET projects, both WebForms and MVC.

There are a lot of examples and articles showing how to use the standard GroupDocs.Viewer's for .NET functionality already, but this time I want to show you something different. Sometimes you may want to change, extend or supplement Viewer's functionality. For example, you may want to restrict the download, copy or print options. You can disable these by simply configuring Viewer's options, sure. But what if you want a more advanced and intelligent solution? For example, you may need to allow only registered users to be able to download a document, and restrict this option for unregistered users. This article shows you how to achieve this.

GroupDocs.Annotation for Java – Integrating with a Java Web Project

GroupDocs.AnnotationGreetings everyone!
As you may already know, we've recently released the GroupDocs.Annotation for Java library. It is basically an HTML5-based document viewer that comes with a comprehensive set of tools for marking up and commenting on documents of almost 50 file formats. The library provides end users with the ability to view, annotate and collaborate on documents in real time.

Today we'd like to present you with a quick guide on how to set up a basic Java web application with the document annotation capability. In this tutorial you will find out how to initialize and use AnnotationHandler, the main class that represents the GroupDocs.Annotation library itself. Further, you will find a request mapping, so that you can correctly map user actions to the server side code. Another nice feature is the configuration of the SignalR library, the tool that enables real time collaboration mode, when several parties can annotate the same document simultaneously and see each other's comments in real time.

For those of you who would like to try and test the GroupDocs.Annotation for Java web application, but have no time for creating it from scratch, we provide the project source code. So feel free to download, deploy and configure it for your needs.

If you are using NetBeans, you can just create a new "Web Application with Existing Sources", point to the sample sources and start it from the IDE.

GroupDocs.Annotation for Java Library – Annotate PDF, Office and Image Files within Your Java Apps

Java PDF AnnotationWe are pleased to inform developers, especially those of you who prefer the Linux platform, about the release of the GroupDocs.Annotation for Java library. It is an HTML5 standard compliant library that allows you to display PDF, Microsoft Office and image files and comes with a comprehensive set of document commenting and markup tools. The viewer can work two ways: by rasterizing documents or by converting them to a combination of SVG, HTML and CSS. Both methods deliver clear, high-fidelity rendering. Key benefits include: 

  • Seamlessly enable end users to view, annotate, share and print more than 45 document formats, including PDF, Microsoft Office (DOC, DOCX, XLS, XLSX, PPT, PPTX, etc.) and OpenDocument files (ODT, ODS, etc.), plain text documents, CAD and raster images within your Java apps.
  • Documents can be rendered as real text files (HTML5 based technology of HTML, CSS and SVG combination), meaning users can select, mark up, strikeout and comment on text within a document.
  • GroupDocs.Annotation for Java is a 100% native solution - you don't need any 3rd party software.
  • Simplicity of installation - the library can be deployed with a packaged JAR file or hosted within your own servlet container.
  • Using only a few JavaScript lines or an iframe, you can integrate the UI, which can be easily customized to fit the look and style of your own app.
  • GroupDocs.Annotation for Java is set up to work cross-domain using JSONP and CORS, so it's designed to be run external to projects. Thanks to this, PHP and RoR Linux-based applications can use it from within the same server.
  • The library allows end users to view and annotate documents from any web-enabled device, including tablets and mobiles, and using any HTML5 compliant web-browser.

For more information on the GroupDocs.Annotation for Java library, please visit the product page, check out code samples and download a free evaluation copy.

Also, please feel free to contact our sales team for an evaluation license which enables you to test all features without any limits during 30 days for free.
