Usage examples

The examples below illustrates the changes introduced in this release:

Recognize image with automatic noise removal

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Set license
            License lic = new License();
            lic.SetLicense("Aspose.Total.lic");
            // Image path
            string image = "noisy.jpg";
            // Recognize
            RecognitioResult result = api.RecognizeImage(image, new RecognitionSettings {AutoDenoising = false});
            //Print recognition results
            Console.WriteLine(result.RecognitionText);
        }
    }
}

Recognize image with tabular content

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Set license
            License lic = new License();
            lic.SetLicense("Aspose.Total.lic");
            // Image path
            string image = "table.jpg";
            // Recognize
            RecognitioResult resultTable = api.RecognizeImage(image, new RecognitionSettings {DetectAreasMode = DetectAreasMode.TABLE});
            //Print recognition results
            Console.WriteLine(resultTable.RecognitionText);
        }
    }
}
