Public API changes and backwards compatibility

This section lists all public API changes introduced in Aspose.OCR for Java 22.9 that may affect the code of existing applications.

Added public APIs:

The following public APIs have been introduced in this release:

Receipt recognition.

Added a method RecognizeReceipt that is specifically tailored for extracting text from printed receipts.

This method uses a special recognition settings object, ReceiptRecognitionSettings, which is a subset of the existing image recognition settings.

Recognition of small fonts

Added a method setUpscaleSmallFont to image recognition setting:

Call	Behavior
`setUpscaleSmallFont(false)`	Use standard recognition flow (default). Very small fonts and dense lines may not be recognized.
`setUpscaleSmallFont(true)`	Activate a special upscaling algorithm that greatly improves small font recognition and line detection.

Updated public APIs:

No changes.

Removed public APIs:

No changes.

Usage examples

The examples below illustrates the changes introduced in this release:

Receipt recognition.

// Create instance of OCR API
AsposeOCR api = new AsposeOCR();
// Recognize Ukrainian text
ReceiptRecognitionSettings recognitionSettings = new ReceiptRecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from receipt
RecognitionResult result = api.RecognizeReceipt("source.png", recognitionSettings);
System.out.println("Recognition result:\n" + result.recognitionText);

Recognition of small fonts

// Create instance of OCR API
AsposeOCR api = new AsposeOCR();
// Activate font upscaling 
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setUpscaleSmallFont(true);
// Extract text from image
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
System.out.println("Recognition result:\n" + result.recognitionText);
