Aspose.OMR Cloud SDK for .NET


Aspose.OMR Cloud SDK for .NET helps developers perform optical mark recognition (OMR) in the cloud. They can seamlessly integrate OMR capabilities in their .NET applications which enable their end-users to generate OMR templates via text mark-up that in turn are used to generate test sheets, surveys, or other quiz-based documents. Aspose.OMR Cloud SDK for .NET lets you take scanned photos and images as input recognize the scanned data from these image-based documents and export the recognized results into CSV format. Aspose.Imaging Cloud SDK lets you define JSON rules for answer grading.

Quickly Get Started with OMR REST API

Aspose.OMR Cloud SDK for .NET is completely independent of your operating system, database system or development language. You can use any language or platform that supports HTTP to interact with our API. However, manually writing client code can be difficult, error-prone and time-consuming. Therefore, we have provided .NET SDK to make it easier to integrate your applications with our cloud OMR SDK. If you use the SDK, it hides the REST API calls and lets you use the features of the API in a native way for your .NET application.

It is easy to get started with Aspose.OMR Cloud SDK for .NET and there is nothing to install. Simply create an account at Aspose for Cloud and get your application information. Once you have the App SID & KEY, you are ready to give the Aspose.OMR Cloud SDK for .NET a try on any supported platforms.

Markup for OMR Template Generation

Aspose.OMR Cloud SDK for .NET allows developers to use markup to generate OMR templates. This markup support several types of elements. These elements include, text, choice box (question), answer sheet (several column of questions), grid (complex values that consist of similar sections), image (e.g. logo), barcode (barcodes, QR-codes, aruco codes).

GUI Application for OMR Template Management

Along with, Aspose.OMR Cloud SDK for .NET, you can also download an MSI package that installs a light-weight OMR client application which lets you create your own OMR templates. Using Aspose OMR client application you can also make corrections to existing OMR templates and perform optical mark recognition via Aspose.OMR Cloud engine. A repository is also provided which contains data and configuration files to be used in our OMR SDK demo project.
