Get Started with Image Scanning

It is easy to get started with Aspose.OCR 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 a try to Aspose.OCR Cloud SDK for .NET. 

Scan Images via Cloud OCR SDK

Optical character recognition can be performed either on a whole image or on a specific portion of the image. If the required characters are all over the image then scanning the whole image is the better option. If you want to scan partial image then specify a rectangular area containing the characters. Aspose.OCR Cloud SDK for .NET allows passing X and Y coordinates from where the rectangle is supposed to be started as well as its width and height.

Once the character recognition operation is initiated within the specified rectangular area, the cloud OCR SDK will read the characters and font information from that area and return the response in XML or JSON format.

  • Scan whole or partial image for character recognition
  • Recognize text from a rectangular area
  • Specify rectangular area using X and Y coordinates, height and width
  • Optical Character Recognition And Font Attributes Support

Extract OCR or HOCR Text from Images - C#

OcrV2Api target = new OcrV2Api(APIKEY, APPSID, BASEPATH);
storageApi.PutCreate("Sampleocr.bmp", "", "", System.IO.File.ReadAllBytes(Path.Combine(DataFolder, name)));
Com.Aspose.Ocr.Model.OCRResponse actual;
actual = target.OcrV2GetRecognizeDocument("Sampleocr.bmp", storage, folder);

Recognize Characters of Different Languages

The characters of different languages have different representations. If we combine the languages with the font types and styles - it makes a large set of characters to be recognized from an image. Aspose.OCR Cloud SDK for .NET handles this task very elegantly as it can recognize text in English, French and Spanish languages. When talking about specific fonts, this API is capable of extracting text in Arial, Times New Roman, Courier New, Verdana, Tahoma and Calibri fonts with regular, bold or italic styles from images.
