Public API changes and backwards compatibility

This section lists all public API changes introduced in Aspose.OCR for Python via .NET 23.7.1 that may affect the code of existing applications.

Added public APIs:

The following public APIs have been introduced in this release:

`RecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

This setting is applicable when using one of the following document area detection modes:

DetectAreasMode.PHOTO
DetectAreasMode.COMBINE
DetectAreasMode.TABLE
DetectAreasMode.CURVED_TEXT

`Aspose.OCR.ReceiptRecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background in scanned or photographed receipts.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

`IDCardRecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background in scanned or photographed ID cards.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

`PassportRecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background in scanned or photographed passports.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

`CarPlateRecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background in photographed vehicle license plates.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

`InvoiceRecognitionSettings.automatic_color_inversion`

When set to true, Aspose.OCR for Python via .NET uses a special OCR algorithm for automatic detection and accurate recognition of of white text on a dark/black background in scanned or photographed invoices.

Unless you are optimizing every aspect of recognition (for example, for online applications or entry-level devices), do not disable this setting.

Examples

The examples below illustrates the changes introduced in this release:

Automatic handling of inverted texts

# Instantiate Aspose.OCR API
api = ocr.AsposeOcr()
# Add an image to the recognition batch
input = ocr.OcrInput(ocr.InputType.SINGLE_IMAGE)
input.add("source.png")
# Apply inverted text detection
settings = ocr.RecognitionSettings()
settings.automatic_color_inversion = False
settings.detect_areas_mode = ocr.DetectAreasMode.TABLE
# Extract text from an image
result = api.recognize(input, settings)
# Print recognition result
print(result[0].recognition_text)
