Added public APIs:
The following public APIs have been introduced in Aspose.OCR for Python via .NET 23.12.1 release:

Examples
The code samples below illustrate the changes introduced in this release:
Recognize handwritten memos
import aspose.ocr as ocr
# Initialize an instance of Aspose.OCR
api = ocr.AsposeOcr()
# Add images to recognition batch
input = ocr.OcrInput(ocr.InputType.SINGLE_IMAGE)
input.add("memo.jpg")
# Extract and show handwritten text
res = api.recognize_handwritten_text(input)
print(res[0].recognition_text)
Enable retrieving properties from Malagasy passports
import aspose.ocr as ocr
# Instantiate Aspose.OCR API
api = AsposeOcr()
# Add image to the recognition batch
input = OcrInput(InputType.SINGLE_IMAGE)
input.add("passport1.png")
input.add("passport2.png")
# Enable retrieving properties from Malagasy passports
recognitionSettings = PassportRecognitionSettings()
recognitionSettings.country = ocr.Country.MADAGASCAR
# Recognize passports
results = api.recognize_passport(input, recognitionSettings)
# Print passport texts
for result in results:
print(result.recognition_text)
