• Support English, French, Spanish and Portuguese text.
• Detect and read popular font faces such as Arial, Times New Roman, Courier New, Tahoma, Calibri & Verdana.
• Supports regular, bold, and italic font styles.
• Scan the whole image or only a specific portion of the image.
• Scan rotated images.
• Application of various noise removal filters to assist image recognition.

What's new in v22.9.0

Receipt Text Recognition via OCR

Introduced a specialized method RecognizeReceipt that is used to extract text specifically from printed receipts.

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.ReceiptRecognitionSettings recognitionSettings = new Aspose.OCR.ReceiptRecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Ukr;
Aspose.OCR.RecognitionResult result = recognitionEngine.RecognizeReceipt("receipt.png", recognitionSettings);
Console.WriteLine(result.RecognitionText);

Small Fonts Recognition

Introduced a new image detection setting, UpscaleSmallFont, that enhances the recognition accuracy of small fonts and lines.

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.UpscaleSmallFont = true;
Aspose.OCR.RecognitionResult result = recognitionEngine.RecognizeImage("source.png", recognitionSettings);
Console.WriteLine(result.RecognitionText);

Cyrillic Characters Recognition

Improved the image recognition via OCR by adding the ability to recognize all Cyrillic characters.

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Cyrillic;
Aspose.OCR.RecognitionResult result = recognitionEngine.RecognizeImage("source.png", recognitionSettings);
Console.WriteLine(result.RecognitionText);

Batch Image Recognition & Conversion

Added the ability to recognize all images from a specific folder via OCR API and save then all as PDF pages.

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
// Recognize all images from the folder
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.RecognizeMultipleImages("C:/images/", recognitionSettings);
// Save all pages as PDF
Aspose.OCR.AsposeOcr.SaveMultipageDocument("result.pdf", Aspose.OCR.SaveFormat.Pdf, results);
