Usage Example

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Get API
            AsposeOcr api = new AsposeOcr();

            // Create license
            License lic = new License();

            // Set license
            lic.SetLicense("Aspose.Total.lic");

            // Get pdf for recognize
            string imagePdf = "D://img.pdf";

            // Recognize pdf from stream           
            using (MemoryStream ms = new MemoryStream())
            {
                using (FileStream file = new FileStream(imagePdf, FileMode.Open, FileAccess.Read))
                {
                    file.CopyTo(ms);

                    DocumentRecognitionSettings set = new DocumentRecognitionSettings();
					List<RecognitionResult> results = api.RecognizePdf(ms, set);     

		            // Print result
					foreach (var result in results)
					{
						Console.WriteLine(result.RecognitionText);
					}
				}
			}

			// Get image for recognize
            string image = "D://img.png";

			// Recognize image
			RecognitionResult result = api.RecognizeImage(imgPath, new RecognitionSettings { DetectAreas = false});

			// Save result to stream
			using (MemoryStream msout = new MemoryStream())
            {
                result.Save(msout, SaveFormat.Text);
				// check
                //using (var fileStream = new FileStream("file_for_check.txt", FileMode.Create))
                //{
                //    msout.Seek(0, SeekOrigin.Begin);
                //    msout.CopyTo(fileStream);
                //}
            }

			// Get words coordinates
			List<Rectangle> resultRectangles = api.GetRectangles(image, AreasType.WORDS, true);
			// Print result
			foreach (Rectangle rectangle in resultRectangles)
			{
				Console.WriteLine($"x={rectangle.X}, y={rectangle.Y}, width={rectangle.Width}, height={rectangle.Height}");
			}		

        }
    }
