Get Started with Optical Mark Recognition REST API

It is easy to get started with Aspose.OMR Cloud because there is nothing to install. Simply create an account at Aspose for Cloud and get your application information. Once you have acquired the app key & SID, you are ready to use the Aspose.OMR Cloud REST API with any language, on any platform.

.NET Client Application for Learning

Aspose.OMR Cloud comes with a .NET client application, which is provided for demonstration and as a jump start for the developers. The WPF client application allows you to create template markup & save it for later processing or manipulate existing templates. You can also perform basic OMR recognition tasks, and learn how to work with Aspose.OMR Cloud in the process. 

Recognize Marks from Scans or Photos

Aspose.OMR Cloud is equally good for scanned documents as well as photos of the documents because it can process rotated and perspective corrupted images with high accuracy.

Perform OMR on Image - C#


// Instantiate OMR API for accessing OMR functions
OmrApi omrApi = new OmrApi(APIKEY, APPSID, BASEPATH);
// Set task parameters
OMRFunctionParam param = new OMRFunctionParam();
param.FunctionParam = packedTemplateJson;
// Upload source file to aspose cloud storage
storageApi.PutCreate("AnswerSheet.png", "", "", System.IO.File.ReadAllBytes(pathToTheImage + "AnswerSheet.png"));
// Invoke Aspose.OMR Cloud SDK API to run OMR task
Com.Aspose.OMR.Model.OMRResponse response = omrApi.PostRunOmrTask("AnswerSheet.png", "CorrectTemplate", param, "", null);

Generate Template - C#


// Instantiate parameters class and pass Template ID
OMRFunctionParam param = new OMRFunctionParam();
param.FunctionParam = @"{ ""ExtraStoragePath"":""Logos""}";
// call OMR API with specified parameters
omrApi.PostRunOmrTask("AnswerSheet.txt", "GenerateTemplate", param, null, null);

Correct Template - C#


// Instantiate parameters class and pass Template ID
OMRFunctionParam param = new OMRFunctionParam();
param.FunctionParam = packedTemplateJson;
// call OMR API with specified parameters
omrApi.PostRunOmrTask("AnswerSheet.png", "CorrectTemplate", param, null, null);

Finalize Template - C#


// Instantiate parameters class and pass Template ID
OMRFunctionParam param = new OMRFunctionParam();
param.FunctionParam =  "5b535525-72fe-453f-83e8-5a058569620e";
// call OMR API with specified parameters
omrApi.PostRunOmrTask("AnswerSheet.omrcr", "FinalizeTemplate", param, null, null);

Recognize Image - C#


// Instantiate parameters class and pass Template ID
OMRFunctionParam param = new OMRFunctionParam();
param.FunctionParam = "5b535525-72fe-453f-83e8-5a058569620e";
// call OMR API with specified parameters
omrApi.PostRunOmrTask("photo.jpg", "RecognizeImage", param, null, null);

Export Results in CSV Format

Along with JSON based responses, Aspose.OMR Cloud also offers to export the results in CSV format. You can set the API to export the results in a CSV file while saving it in your downloads folder.

Use any Language or any Third Party Storage

Aspose.OMR Cloud can be used with any language or platform which supports HTTP requests and responses. You can also use Aspose.OMR Cloud with many third party storages including Amazon S3, Google Cloud, Google Drive and DropBox.
