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}");
}
}
}
}
